(10 x _) x 6 = _ x (2x6)
(I need help)
Answer:
660
Step-by-step explanation:
(10 x 6) x 6 = 360
and
_ x (2 x 6) = _ x 12
To find the missing value, we need to use the distributive property of multiplication, which states that a(b + c) = ab + ac.
Therefore, we can rewrite the right-hand side of the equation as:
_ x (2 x 6) = _ x 12
_ x 12 = 12_
Now we can substitute this into the original equation:
(10 x 6) x 6 = 360
60 x 6 = 360
360 = 360
So, the missing value is 60.
Therefore,
(10 x 6) x 6 = 360 = 60 x 12 = _ x (2 x 6)
and
_ x (2 x 6) = 60 x 12.

Today, you are retiring. You have a total of R411 016 in retirement savings, and have the funds invested such that you expect to earn an average of 7,10% interest compounded monthly on this money, throughout your retirement years. You want to withdraw R2 500 at the beginning of every month, starting today. How long will it be until you run out of money?
Answer:
Step-by-step explanation:
To determine how long your retirement savings will last when withdrawing R2 500 at the beginning of every month, we need to use a financial formula called the future value of an annuity formula, which calculates the future value of a series of equal withdrawals made at regular intervals over a fixed period of time.
In this case, we want to calculate how many months it will take for your retirement savings to be depleted, given that you will be withdrawing R2 500 at the beginning of every month. The formula is:
n = [log(PMT/(PMT - r*PV))]/[log(1+r)]
where:
PMT = R2 500 (the regular payment you will make every month)
r = 7,10%/12 (the monthly interest rate, which is the annual rate of 7,10% divided by 12)
PV = R411 016 (the present value of your retirement savings)
Using the above values in the formula, we get:
n = [log(2500/(2500-((7.10%/12)*411016))))]/[log(1+(7.10%/12))]
n = 182.1
Therefore, it will take approximately 182.1 months, or 15.2 years, until you run out of money, assuming all other factors remain constant, and you withdraw R2 500 at the beginning of each month.
Ben borrowed $10,000 from the bank. The rate is 12% and he will pay it back in 12 months. How much does he owe the bank?
Answer:
Step-by-step explanation:
Assuming that the interest is compounded monthly, Ben's total amount owed to the bank after 12 months can be calculated using the following formula:
A = P*(1+r/n)^(n*t)
Where:
P = principal amount borrowed = $10,000
r = annual interest rate as a decimal = 0.12
n = number of times the interest is compounded per year = 12 (monthly)
t = time period for which the interest is applied in years = 1
Plugging in the values, we get:
A = 10,000*(1+0.12/12)^(12*1)
A = $11,268.70
Therefore, Ben owes the bank a total of $11,268.70 after 12 months.

The correct answer is B. 9 3/10. An improper fraction is a fraction where the numerator (the top number) is larger than the denominator (the bottom number).
What is a fraction?A fraction is a number that represents a part of a whole. It is a number that is written as two numbers separated by a line, one above the other. The top number is called the numerator and it represents the number of parts being considered.
In the given example, 49/10 is an improper fraction. To convert this improper fraction into a whole number or a mixed number, you need to divide the numerator by the denominator. When you divide 49 by 10, the answer is 4 with a remainder of 9. This is how you get the mixed number 9 3/10 which is the same as 49/10.
9 3/10 is a mixed number which consists of a whole number and a fraction. The whole number is 9 and the fraction is 3/10. The fraction 3/10 can also be written as its simplest form of 1/10 by dividing the numerator and the denominator by 3.
To check if the answer is correct, you can multiply the whole number (9) and the denominator (10) of the mixed number first, and then add the numerator (3) to get the answer of 49. So, 9 x 10 + 3 = 90 + 3 = 93. The answer is 93, which is the same as the numerator of the given improper fraction (49).

The length of the longer leg of a 30 60 90 triangle is 6. The hyp is 9.
State the solution in Simple Root Form:
State the solution to the nearest tenth:
Step-by-step explanation:
there is something severely wrong with the problem definition.
when the Hypotenuse = 9, there is no 30-60-90 triangle with a leg = 6.
and when we are just focusing that this is a right-angled triangle with the Hypotenuse = 9, then 6 cannot be the longer leg.
it is also not clear what the solution is supposed to be. the 2nd leg ? the area ? the perimeter ? the height(s) ? ...
what ?
so, all I can do here is to show you why I said what I said :
30-60-90 triangle with Hypotenuse = 9
then the longer leg is opposite of the 60° angle and therefore sin(60)×9 = 7.794228634...
the shorter leg is opposite of the 30° angle and therefore sin(30)×9 = 0.5×9 = 4.5
a right-angled triangle with Hypotenuse = 9, one leg = 6 gives us per Pythagoras for the other leg
9² = 6² + leg²
81 = 36 + leg²
45 = leg²
leg = sqrt(45) = 6.708203932...
so, you see, as stated above, there is no leg with the length 6 in such a 30-60-90 triangle.
and in a more general right-angled triangle, if one leg = 6, then the other leg is actually longer.
therefore, there is everything wrong with the problem definition.

Guitar tabs are generally considered easier to read than regular musical notation because they are written in a language that most guitarists are familiar with.
What is Guitar?Guitar is a stringed musical instrument played with the fingers or a pick. It is one of the most popular instruments in the world and is widely used in genres such as rock, jazz, blues, country, folk, and classical.
Unlike traditional notation, guitar tabs do not require any knowledge of music theory to understand. Instead, they are laid out in a straightforward format that conveys the pitch of a note and the timing of when it should be played. This makes it easier for most guitarists to quickly learn a new piece of music without having to spend time studying the complexities of traditional notation. Additionally, guitar tabs also offer an easy way to determine the fingering of certain chords or techniques.
While guitar tabs are easier to read than traditional notation, they do have some drawbacks. For one, guitar tabs cannot convey the same level of detail about a piece of music as traditional notation can. Additionally, it can be difficult for some to distinguish between rhythm and lead parts when reading guitar tabs. Finally, guitar tabs do not easily convey the dynamics or expression of a piece of music, which are important to consider when playing music.

What is the Alternate Segment Theorem?
The Alternate Segment Theorem is a theorem in geometry that relates the angles formed by a line that is tangent to a circle and a chord of that circle. The theorem states that the angle formed by a tangent and a chord of a circle is equal to the angle that is subtended by the chord in the opposite segment of the circle
In a circle, the angle formed by a chord and a tangent that intersect at a point on the circle is equal to half the measure of the arc intercepted by the chord.
Therefore, if the arc intercepted by the chord is 65 degrees, then the angle formed by the chord and the tangent is half of 65 degrees, which is:
65 degrees / 2 = 32.5 degrees
So, the angle X made by the chord and the tangent is 32.5 degrees.

Point M is a minimum value of the function. What is the equation of a cosine function, using radians, that gives the
volume as a function of time?
Enter your numbers in the boxes to complete the equation.
ANSWER FAST PLEASEEE
Y = 5 cos(0.3185x) + 10 is the volume of oxygen as a function of time can be modeled by this cosine function.
What is cosine function ?
The cosine function is a mathematical function that relates the ratio of the sides of a right triangle. In a right triangle, the cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse in a right triangle. The cosine function is periodic, meaning it repeats itself at regular intervals, and has a range of values between -1 and 1. It is commonly used in mathematics, physics, and engineering to model periodic phenomena such as sound waves, electromagnetic waves, and oscillations.
According to the question:
To find the equation of the cosine function, we need to identify the amplitude, period, phase shift, and vertical shift of the function based on the given information.
Since point M is the minimum value of the function, the vertical shift is 10. This means that the equation of the function is of the form:
Y = A cos(Bx - C) + D
where D = 10.
To find the amplitude, we need to find the distance between the maximum and minimum values of the function. Since the graph of a cosine function oscillates between its maximum and minimum values, the amplitude is half the distance between these values.
From the graph, we can see that the maximum value of the function is 20, so the distance between the maximum and minimum values is:
20 - M = 20 - 10 = 10
Therefore, the amplitude is:
A = 10/2 = 5
To find the period, we need to find the distance between two consecutive peaks or troughs of the function. From the graph, we can see that the distance between two consecutive peaks is approximately 6.28 units. This means that the period is:
P = 6.28
To find the phase shift, we need to find the horizontal shift of the function from its standard form. Since the minimum value of the function occurs at x = 0, the phase shift is:
C =
Therefore, the equation of the cosine function is:
Y = 5 cos((2π/P)x - C) + D
Y = 5 cos((2π/6.28)x) + 10
Simplifying,
Y = 5 cos(0.3185x) + 10
So, the volume of oxygen as a function of time can be modeled by this cosine function.

The average overseas trip cost 2708 per visitor. If we assume a normal distribution with a standard deviation of 405 what is the probability that the cost for a randomly selected trip is more than 3000? If we elect a random sample of 30 overseas trips and find the mean of the sample, what is the probability that the mean is greater than 3000
Randomly selected trip: 24.5% chance > $3000. Sample mean of 30 trips: very small chance > $3000.
Utilizing z-score recipe:
z = (x - μ)/σ
where x is the worth we're keen on, μ is the mean, and σ is the standard deviation.For the primary inquiry:
z = (3000 - 2708)/405 = 0.69
Utilizing a standard typical circulation table or number cruncher, we can track down that the likelihood of getting a z-score more prominent than 0.69 is around 0.245. Consequently, the likelihood that the expense for a haphazardly chosen trip is more than 3000 is around 0.245 or 24.5%.
For the subsequent inquiry:
The example size (n) = 30, and the standard deviation (σ) = 405/sqrt(30) = 74.02 (approx.)
z = (3000 - 2708)/74.02 = 3.94
Utilizing a standard typical dissemination table or number cruncher, we can track down that the likelihood of getting a z-score more prominent than 3.94 is tiny, near 0. Consequently, the likelihood that the mean expense of an example of 30 abroad excursions is more noteworthy than 3000 is tiny.

The probability that the mean is greater than 3000 is 24.5%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, the average overseas trip cost 2708 per visitor, assuming a normal distribution with a standard deviation of 405 what is the probability that the cost for a randomly selected trip is more than 3000
z-score:
z = (x - μ)/σ
where μ is the mean, and σ is the standard deviation.
So,
z = (3000 - 2708)/405 = 0.69
Z-score 0.69 = 0.245.
Thus, the likelihood that the expense of the chosen trip is more than 3000 is around 0.245 or 24.5%.
The sample size (n) = 30, and the standard deviation (σ) = 405/√(30) = 74.02 (approx.)
z = (3000 - 2708)/74.02 = 3.94
z-score 3.94 = 0.
Thus, the likelihood that the mean expense of an example of 30 abroad excursions is more noteworthy than 3000 is tiny.

Crysta! is on a bus in France with her family. She sees the top of the Eiffel Tower at an angle of 27° If the tower is 986 feet tall, how far away is the bus?
Answer:
1935.2 ft
Step-by-step explanation:
Picture a right triangle with distance from tower to the bus (x) as the base, and height of the tower 986 ft as the height (y). Find distance from tower to bus using tan27 = y/x =986/x. Solve for x:
x = 986/tan27 = 1935.2 ft
if the mean of a symmetric distribution is 130 which of these values could be the median of the distribution
in a symmetric distribution, the value that could be the median of the distribution must be equal to the mean.
In probability and statistics, the mean and median are two measures of central tendency that are commonly used to describe a data set. The mean, also known as the arithmetic mean or average, is calculated by summing up all the values in the data set and dividing by the total number of values. The median, on the other hand, is the middle value of a data set when the values are arranged in order from lowest to highest.
For a symmetric distribution, the mean and median are the same, because the data values on one side of the mean balance out the values on the other side. In other words, if the distribution is symmetric, then the data values are evenly distributed around the mean.
In this case, if the mean of a symmetric distribution is 130, then the median must also be 130. This is because the median is the middle value of the data set, and in a symmetric distribution, the middle value is the same as the mean.
To illustrate this, consider a simple example of a symmetric distribution with the following values: 125, 130, 135, 140. The mean of this distribution is (125 + 130 + 135 + 140) / 4 = 132.5. However, the median is the middle value of the data set, which is 130. Since the distribution is symmetric, the middle value is the same as the mean.
Therefore, in a symmetric distribution, the value that could be the median of the distribution must be equal to the mean.

Jaylen estimates the side of the square to be 8.5 inches long. The actual length of the side of the square is 8.3 inches long. What is the percent error of the area of the two squares?
Answer:
4.88%
Step-by-step explanation:
All sides of a square are equal
let x = length of a side
Area = x·x = x²
Estimated area = (8.5)² = 72.25 in²
Actual area = (8.3)² = 68.89 in²
percent error = (actual area - estimated area) / (estimated area) x 100
% error = (68.89 - 72.25) / (68.89) x 100 = -4.88% the negative sign means the estimate was higher than the actual.

The tax was 7%, tag fee was $125, and title fee was $75. He bought an extended warranty for $700, which was financed into the total cost of the truck. The interest rate was 6.5% for 5 years. How much are the monthly payments?
The total price of the vehicle would be $18,192.88.
The total deferred price of the car would be $11,191.60.
The length of the financing agreement is 68 months .
The total deferred price after the payments was $19,601.84.
The monthly payments would be $516.92.
How to find the price of the vehicle ?Subtotal = Base price + Options + Destination charges
Subtotal = $14,500 + $982 + $592 = $16,074
Dealer preparation = 5% of subtotal
Dealer preparation = 0.05 x $16,074 = $803.70
Sales tax = 7% of subtotal
Sales tax = 0.07 x $16,074 = $1,125.18
Total price = Subtotal + Dealer preparation + Sales tax + Tag fee + Title fee
Total price = $16,074 + $803.70 + $1,125.18 + $145 + $45 = $18,192.88
How to find the total deferred price ?Tax = 8% of selling price = 0.08 x $8,850 = $708
Tag fee = $130
Title fee = $35
Total amount financed = Amount financed + Tax + Tag fee + Title fee = $7,350 + $708 + $130 + $35 = $8,223
Annual interest rate = 9.5%
Number of years financed = 3
Total finance charges = $8,223 x 0.095 x 3 = $2,341.595
Total financed amount = $8,223 + $2,341.595 = $10,564.595
Monthly payments = Total financed amount / (Number of years financed x 12 months) = $10,564.595 / (3 x 12) = $293.4615
Total deferred price = Selling price + Total finance charges = $8,850 + $2,341.595 = $11,191.595
How to find the length of the financing agreement ?Total deferred price = $28,000
Down payment = $2,100
Total amount financed = Total deferred price - Down payment = $28,000 - $2,100 = $25,900
Monthly payments = $380
Number of months = Total amount financed / Monthly payments = $25,900 / $380 = 68.16
The financing agreement is approximately 68 months long.
How to find the deferred price after the payments ?Sticker price = $19,200
Discount = 6% of sticker price = 0.06 x $19,200 = $1,152
Selling price = Sticker price - Discount = $19,200 - $1,152 = $18,048
Sales tax = 8% of selling price = 0.08 x $18,048 = $1,443.84
Total price = Selling price + Sales tax + Tag fee + Title fee = $18,048 + $1,443.84 + $65 + $45 = $19,601.84
How to find the monthly payments ?Using the formula for monthly payments on a loan:
P = (PV x r x (1 + r)^ n) / ((1 + r) ^ n - 1)
= ($26,515.80 x 0.005265 x (1 + 0.005265) ^ 60 ) / ((1 + 0.005265) ^ 60 - 1) = $516.92

Martha made 2 2/3 pounds of pasta. she divided the pasta into fourths. how much pasta is in each portion?
Each portion of pasta is 2/3 pounds.
What is portion?Prοpοrtiοn or portion, in general, is referred tο as a part, share, οr number cοnsidered in cοmparative relatiοn tο a whοle. Prοpοrtiοn definitiοn says that when twο ratiοs are equivalent, they are in prοpοrtiοn. It is an equatiοn οr statement used tο depict that twο ratiοs οr fractiοns are equal.
To divide 2 2/3 pounds of pasta into fourths, we can first convert the mixed number to an improper fraction:
2 2/3 = (2 x 3 + 2)/3 = 8/3
Then, we can divide 8/3 by 4 to find the amount of pasta in each portion:
8/3 ÷ 4 = (8/3) x (1/4) = 2/3
