Based on the given information, Mike's grandmother deposited $6,000 into the savings account.
What is simple interest?
Simple interest is a method of calculating interest on a principal amount, where the interest is calculated only on the original amount of the loan or investment, without taking into account any interest that may have been previously earned. The formula for calculating simple interest is I = P * r * t, where I is the interest earned, P is the principal amount, r is the annual interest rate as a decimal, and t is the time period in years.
We are given that the interest rate is 8% and the interest earned after 10 years is $4,800. So we can write:
4,800 = P * 0.08 * 10
Simplifying the equation, we get:
4,800 = 0.8P
Dividing both sides by 0.8, we get:
P = 6,000
Therefore, Mike's grandmother deposited $6,000 into the savings account.

The inequality that is true for all values of x is:
√(4x²) ≤ 4x²
Which of the inequalities is true for all values of x?Let's try to find which inequality is true for all real values of x.
For example, let's look at option C, here we have the inequality:
4(x² - 3) ≤ 3(x² - 4)
Let's expand both sides to get:
4x² - 12 ≤ 3x² - 12
4x² ≤ 3x²
4 ≤3
We removed the x-variable, but 4 is not smaller or equal to 3, so this is false.
Now option D, we have:
√(4x²) ≤ 4x²
Notice that bout outcomes are always positive, but in the left side we have a square root.
We can simplify this to get:

What is 3 and 3 over 5 times 2 and 1 over 4? hurry
Answer:81/20 or 4 1/20
Step-by-step explanation:
To solve this problem, we need to use the rules of multiplication and fractions.
First, we need to convert the mixed numbers to improper fractions:
3 and 3/5 = (5 * 3 + 3) / 5 = 18/5
2 and 1/4 = (4 * 2 + 1) / 4 = 9/4
Now we can multiply the two fractions:
(18/5) * (9/4)
To simplify this expression, we can cancel out any common factors between the numerators and denominators:
(18/5) * (9/4) = (2 * 9)/(5 * 2) * (9/4) = 9/5 * 9/4
Then, we can multiply the numerators and denominators separately:
9/5 * 9/4 = (9 * 9) / (5 * 4) = 81/20
Therefore, 3 and 3/5 times 2 and 1/4 is equal to 81/20 or 4 1/20 as a mixed number.

Edwin deposited money into a savings account that pays a simple annual interest rate of 2.4%. He earned $23 in interest after 6 years. How much did he deposit? Round answer to the hundredths place
Edwin deposited $159.72 into the savings account.
What is interest?Interest is the fee paid for having access to borrowed funds. While the interest rate used to compute interest is usually expressed as an annual percentage rate, interest expense or revenue is frequently expressed as a dollar amount.(APR).
We can use the formula for simple interest to solve this problem:
simple interest = principal x rate x time
Where:
principal is the amount of money depositedrate is the annual interest rate (as a decimal)time is the duration of the investment (in years)We know the rate is 2.4% per year, which is equivalent to 0.024 as a decimal. We also know the time is 6 years, and the interest earned is $23. We can plug these values into the formula and solve for the principal:
23 = principal x 0.024 x 6
Simplifying:
23 = 0.144 x principal
Dividing both sides by 0.144:
principal = 23 ÷ 0.144
principal = $159.72 (rounded to the nearest cent)

A bell tolls every 30mins on the journey and at half past the hour. How many times does the bell toll between the times of 11.45am and 3.10pm
The bell tolls 6 times between 11:45 AM and 3:10 PM.
Determine how many times the bell tolls between 11:45 AM and 3:10 PM, follow these steps:
1. Calculate the time interval between 11:45 AM and 3:10 PM:
3:10 PM - 11:45 AM = 3 hours and 25 minutes
2. Find the next bell toll after 11:45 AM:
Since the bell tolls at half past the hour, the next bell toll is at 12:30 PM.
3. Calculate the time interval between 12:30 PM and 3:10 PM:
3:10 PM - 12:30 PM = 2 hours and 40 minutes
4. Divide the time interval by the bell's tolling interval:
2 hours and 40 minutes = 160 minutes
160 minutes / 30 minutes (bell's tolling interval) = 5.33
5. Since the bell can't toll a fraction of a time, round down the result:

How do you graph (4,5) and (2,2) to find the distance between the pionts.
The distance between the points (4, 5) and (2, 2) is approximately 3.61 units.
What is the distance?
To find the distance between two points, we can use the distance formula:
distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
Using the given points (4, 5) and (2, 2), we have:
distance = √[(2 - 4)² + (2 - 5)²]
= √[(-2)² + (-3)²]
= √[4 + 9]
= √13
So the distance between the points (4, 5) and (2, 2) is approximately 3.61 units.
To graph these points, we would plot them on a coordinate plane. The point (4, 5) would be two units to the right of the y-axis and five units up from the x-axis.
The point (2, 2) would be two units to the right of the y-axis and two units up from the x-axis. We could then use a ruler to measure the distance between the two points on the graph to verify that it is approximately 3.61 units.

a connected planar graph has $26$ faces and $v$ vertices, and all its vertices have the same degree. what are all possible values of $v$?
All possible values of v are integers greater than or equal to 28.
In a connected planar graph with 26 faces, the number of edges can be found using Euler's formula, which states that v - e + f = 2 for any connected planar graph. Since the graph is connected and planar, we know that e = 3v/2 - 3 (using the handshaking lemma and Euler's formula), and substituting this into Euler's formula gives:
v - (3v/2 - 3) + 26 = 2
Simplifying this equation yields v = 52 - 2f.
Since all vertices have the same degree, each face must have degree at least 3, and the sum of the degrees of the faces is equal to 2 times the number of edges. Therefore, we have:
3f ≤ 2e = 3v - 6
f ≤ (3v - 6)/3 = v - 2
Combining this with the fact that there are 26 faces, we get:
26 ≤ v - 2
v ≥ 28

prove that ∆ABC=8 ∆EFG
Answer:
To prove that ∆ABC=8 ∆EFG, we need to use the concept of similarity of triangles and the ratio of their corresponding sides.
Given that ∆ABC and ∆EFG are similar triangles, we can write:
AB/EF = BC/FG = AC/EG = k (a constant)
Let's assume that AB = x, BC = y, and AC = z. Similarly, let EF = p, FG = q, and EG = r.
From the given information, we can write:
EF = AB/2 (since E is the midpoint of AB)
FG = BC/2 (since F is the midpoint of BC)
EG = AC/2 (since G is the midpoint of AC)
Substituting these values in the above equation, we get:
x/p = y/q = z/r = k
Now, let's consider the area of the triangles.
Area of ∆ABC = (1/2) * AB * BC * sin(∠BAC)
Area of ∆EFG = (1/2) * EF * FG * sin(∠EFG)
Using the values we have assumed earlier, we get:
Area of ∆ABC = (1/2) * x * y * sin(∠BAC)
Area of ∆EFG = (1/2) * (x/2) * (y/2) * sin(∠EFG)
Simplifying these expressions, we get:
Area of ∆ABC = (xy/2) * sin(∠BAC)
Area of ∆EFG = (xy/8) * sin(∠EFG)
Now, since the triangles are similar, their corresponding angles are equal. Therefore,
sin(∠BAC) / sin(∠EFG) = z/r
Substituting the value of k from earlier, we get:
sin(∠BAC) / sin(∠EFG) = 2k
Solving for sin(∠EFG), we get:
sin(∠EFG) = sin(∠BAC) / (2k)
Substituting this value in the expression for the area of ∆EFG, we get:
Area of ∆EFG = (xy/8) * (sin(∠BAC) / (2k))
Area of ∆EFG = (xy/16) * sin(∠BAC)
Now, substituting the value of the area of ∆ABC in this expression, we get:
Area of ∆EFG = (1/2) * Area of ∆ABC * (1/8)
Area of ∆EFG = (1/16) * Area of ∆ABC
Therefore, we have proved that ∆ABC=8 ∆EFG.

What is y-intercept and slope?The graph's intersection with the y-axis is known as the y-intercept. Finding the intercepts for any function with the formula y = f(x) is crucial when graphing the function. An intercept can be one of two different forms for a function. The x-intercept and the y-intercept are what they are. A function's intercept is the location on the axis where the function's graph crosses it.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. whereas there is a net change in the x coordinate, the y coordinate changes just little.
Given the modeled equation for puppy's growth is 2x - y = -2.
The standard equation of line is y = mx + c.
Converting the given model in standard form we have:
2x - y = -2
-y = - 2x - 2
y = 2x + 2
From the equation we see that the y-intercept is 2 and slope is 2.

a box with a square base and no top is to be built with a volume of 6912 6912 in3 3 . find the dimensions of the box that requires the least amount of material. how much material is required at the minimum?
The box requires a minimum of 4032 square inches of material.
Let's assume that the square base of the box has side length 'x', and the height of the box is 'h'. Then the volume of the box is
V = x^2 × h = 6912
We need to find the dimensions of the box that require the least amount of material. This means we need to minimize the surface area of the box. The surface area of the box is given by
S = x^2 + 4xh
We can solve for 'h' in terms of 'x' using the volume equation
h = 6912 / x^2
Substituting this expression for 'h' into the surface area equation, we get
S = x^2 + 4x(6912/x^2)
Simplifying and taking the derivative of 'S' with respect to 'x', we get
dS/dx = 2x - 27744/x^3
Setting this derivative equal to zero to find the critical points
2x - 27744/x^3 = 0
Multiplying both sides by x^3 and solving for 'x', we get
x = (27744/2)^(1/4) = 18
To confirm that this is a minimum, we need to check the second derivative of 'S' with respect to 'x'
d^2S/dx^2 = 2 + 83208/x^4
At x = 18, we have
d^2S/dx^2 = 2 + 83208/18^4 > 0
Therefore, the critical point at x = 18 corresponds to a minimum surface area.
So the dimensions of the box with the least amount of material are
The side length of the base is 18 inches, and
The height of the box is h = 6912 / 18^2 = 32 inches.
The minimum amount of material required is the surface area of the box, which is
S = 18^2 + 4(18)(32) = 1728 + 2304 = 4032 in^2.

in a distribution for which the mean is 25 and the standard deviation is 5, what percentage of all scores occur at 30 or below?
Step-by-step explanation:
30 is 5 below the mean of 25
this is ONE standard deviation BELOW the mean ( the standard deviation is given as 5)
this represents a Z -score of -1
From Z-score table this represents .1587 of the sample or 15.87 %
The percentage of all scores that occur at 30 or below in a distribution with a mean of 25 and a standard deviation of 5 is 84.13%.
To find the percentage of all scores that occur at 30 or below, we need to calculate the z-score first. The z-score formula is (x - μ) / σ, where x is the score of interest, μ is the mean, and σ is the standard deviation.
So, for x = 30, μ = 25, and σ = 5, the z-score is calculated as (30 - 25) / 5 = 1.
We can then use a standard normal distribution table or a calculator to find the proportion of the area under the curve to the left of z = 1. This gives us the percentage of all scores that occur at 30 or below.
Using a standard normal distribution table, we find that the proportion of the area under the curve to the left of z = 1 is 0.8413.
Therefore, the percentage of all scores that occur at 30 or below in this distribution is 84.13%.

Let’s use Bayes’ theorem to solve this problem. Let A be the event that it rains in Spain and B be the event that hurricanes happen in Hartford. We want to find P(A|B). We know that P(B|A) = 0.08 and P(B|A’) = 0.03 where A’ is the complement of A (i.e., it does not rain in Spain). We also know that P(A) = 1/13 and P(A’) = 12/13.

a person 6 feet tall is walking away from a lamppost that is 15 ft tall at a rate of 6 ft/sec. at what rate is the end of the person's shadow moving away from the lamppost
The rate at which the end of the person's shadow is moving from the lamppost is 4ft/sec.
Let us consider the the distance of the person from the bottom of the lamppost is = xft
therefore the length of shadow is = yft
then the formula is
x + y/15 = y/6
or, 6(x + y) = 15y
=> 6x + 6y = 15y
=> 9y = 6x
therefore, y = 2x/3
Differentiation of both sides w.r.t t
dy/dt = 2/3 × dx/dt
we know that,
dx/dt = 6 ft/sec
then,
dy/dt = 2/3 × 6 => 4 ft/sec
The rate at which the end of the person's shadow is moving from the lamppost is 4ft/sec.
