A flag-shaped like an equilateral triangular has a perimeter of 45 inches. What is the length of each side of the flag?

Answer:

He has 68.8% of his drink left

Step-by-step explanation:

do 32 oz - 10 oz = 22 oz to get how much of his drink is left

To get the percentage, just do what left divided by original amount

so 22/32 = 0.6875 and in percent, that is about 68.8%

Step-by-step explanation:

Since the directrix is vertical, use the equation of a parabola that opens up or down. Find the vertex.

The answer is right angle with leg 3 and 8.

To use the box method to find the area of the parallelogram, we need to divide it into two triangles. One possible way to do this is by drawing a diagonal from (5, 17) to (18, 9), and creating two triangles with vertices (5, 17), (10, 20), and (18, 9), and (5, 17), (13, 6), and (18, 9).

The length of the diagonal can be found using the distance formula:

d = √[(18 - 5)^2 + (9 - 17)^2]

d = √[(13)^2 + (-8)^2]

d = √(169 + 64)

d = √233

Now, the area of the parallelogram is equal to the product of the length of the diagonal and half the height of the parallelogram. One of the cutouts from the box method will be a right triangle with legs equal to half the height and half the length of the diagonal.

Half the height can be found by taking the difference in y-coordinates between (5, 17) and (18, 9) and dividing by 2:

h = (17 - 9)/2

h = 4

Half the length of the diagonal is:

l = √233/2

Using these values, we can check each of the given right triangles to see which one matches the dimensions of the cutout:

A right triangle with legs 5 and 17 does not match, since the legs should be half the diagonal and half the height.

A right triangle with legs 5 and 8 does not match, since the legs should be half the diagonal and half the height.

A right triangle with legs 8 and 11 does not match, since the legs are not proportional to the dimensions of the parallelogram.

A right triangle with legs 3 and 8 matches, since half the diagonal is approximately 7.66 and half the height is 4, and 3 and 8 are proportional to these values.

Therefore, the correct answer is the right triangle with legs of 3 and 8.

Answer:

its the middle one ( 8,11)

Step-by-step explanation:

The area of the sector rounding to the nearest tenth is C. 8377.6 [tex]cm^2[/tex].

The law of cosines is a formula used to find the length of a side or the measure of an angle in a non-right triangle (a triangle that does not have a 90-degree angle).

According to given information:

To find the area of the windshield swept by the wiper blade, we can consider it as a sector of a circle with radius equal to the length of the segment swept by the wiper blade. The length of this segment can be found using the law of cosines:

[tex]c^2 = a^2 + b^2 - 2ab cos(C)[/tex]

where a and b are the lengths of the sides adjacent to the angle C, and c is the length of the side opposite to the angle C.

In this case, we have:

a = 80 cm (length of the wiper blade)

b = 90 cm (length of the swing arm)

C = 120 degrees (angle swept by the swing arm)

Substituting these values, we get:

[tex]c^2 = 80^2 + 90^2 - 2(80)(90)cos(120)[/tex]

[tex]c^2[/tex] ≈ [tex]20418[/tex]

[tex]c[/tex] ≈ [tex]142.8 cm[/tex]

So the radius of the circle is approximately 142.8 cm. The central angle of the sector is 120 degrees, so its measure in radians is 2π/3. Therefore, the area of the sector is:

A = (1/2) * [tex]r^2[/tex] * θ

A = (1/2) * [tex](142.8)^2[/tex] *[tex](2\pi /3)[/tex]

A ≈ 8377.6 [tex]cm^2[/tex]

Rounding to the nearest tenth, we get the answer as C. 8377.6 [tex]cm^2[/tex].

Answer:

Step-by-step explanation:

Let's use a Venn diagram to help us visualize the information given in the problem. We can start with three overlapping circles representing Physics (P), Chemistry (C), and Biology (B), and then fill in the numbers given:

                  P

                /   \

               /     \

              /       \

             CP        BP

              \       /

               \     /

                \   /

                  B

We know that 6 students study pure Chemistry, so we can write this number in the circle for Chemistry (C). We also know that 10 students study pure Physics and 8 students study pure Biology, so we can write these numbers in the circles for Physics (P) and Biology (B), respectively:

                  P (10)

                /   \

               /     \

              /       \

        CP (18)       BP (21)

               \     /

                \   /

                  B (8)

               C (6)

Now we can use the information given in the problem to fill in the remaining numbers:

22 students study Physics and Biology, so this number goes in the overlap between P and B: PB = 22

21 students study Chemistry and Biology, so this number goes in the overlap between C and B: CB = 21

We don't know the number of students who study Physics and Chemistry only, but we can use the fact that 6 students study pure Chemistry to figure it out. Since 18 students study Chemistry and Physics in total, and 6 of them study pure Chemistry, the remaining 18 - 6 = 12 students must study both Chemistry and Physics but not Biology. We can write this number in the overlap between C and P: CP = 12.

                  P (10)

                /   \

               /     \

                  B (8)

               C (6)

Now we can find the total number of students by adding up all the numbers in the Venn diagram:

Total = P + C + B - (CP + CB + PB) + (CPB)

Total = 10 + 6 + 8 - (12 + 21 + 22) + 0

Total = 19

Therefore, the total number of students in the class is 19.

The argument "[tex]2x + 3 = 9,[/tex]" for example, states that the sentence "[tex]2x + 3[/tex]" equals the value "9." The goal of solving equations is to find the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complex, linear or nonlinear, and contain one or more parts. In the equation "[tex]x2 + 2x - 3 = 0[/tex]," the variable x is raised to the second power. Lines are used in many areas of mathematics, including algebra, calculus, and geometry.

  [tex]-kdt=(DT/(T-Ts)[/tex][tex])[/tex]

When both sides are combined, the following results:

[tex]-kt + C = ln|T - Ts|[/tex]

where C is the integration constant. To calculate C, we can start with the assumption that the turkey is 185 degrees Fahrenheit when it comes out of the oven:

[tex]ln|185 - 75| = -k(0) + C[/tex]

[tex]C = ln(110) (110)[/tex]

As a result, the equation relating the temperature of the turkey to time is:

[tex]-kt+In|T-75|=-kt+In(110)[/tex]

[tex]T=e(-ktIn(110)+75[/tex]

[tex]T=110e(-0.5k)+75[/tex]

[tex]T=110e(-0.75k+75 T134.43[/tex] degrees Fahrenheit

Buying a car for $2,500 in 1960 would be like buying a car for $539.23 in 2004 dollars .we can solve by using formula by substituting all details along with consumer price index

what is consumer price index ?

The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a basket of goods and services. The CPI is often used as an indicator of inflation

In the given question,

To compare the dollar amounts over time, we can use the formula V = (A/S) x (C/C'), where:

V = the current value of the old dollar amount

A = the old dollar amount ($2,500 in this case)

S = the starting year's consumer price index (CPI) for the old dollar amount (1960 CPI)

C = the converting year's CPI (2004 CPI)

C' = the starting year's CPI for the converting year (1960 CPI)

Using the formula, we can calculate the current value of $2,500 in 1960 dollars as:

V = (A/S) x (C/C')

V = (2,500/29.6) x (188.9/29.6)

V = 84.46 x 6.380

V = $539.23

The sequence of the function is -34,-34 -8

In mathematics, the common difference is a term used in arithmetic sequences to refer to the fixed difference between any two consecutive terms in the sequence.

An arithmetic sequence is a sequence of numbers in which each term is obtained by adding a fixed value, called the common difference, to the preceding term.

-34 -21 -8 5 ...

f(1) = -34

f(n) = f(n-1) + [n-2]*13 for n = 2, 3, 4, ...

The common difference between consecutive terms of the sequence is 13.

The first term of the sequence is -34, which is f(1).

To get the nth term of the sequence, we add (n-2)*13 to the (n-1)th term of the sequence.

For example, to get the 2nd term of the sequence, we add (2-2)*13 = 0 to the 1st term, -34, which gives us -34.

To get the 3rd term, we add (3-2)*13 = 13 to the 2nd term, which gives us -21+13 = -8.

Answer:

a) To find the probability that the length of the croaker fish is less than 7 inches, we need to calculate the z-score of 7 inches using the formula:

z = (x - mu) / sigma

where x is the length of the fish we are interested in, mu is the mean length of the population, and sigma is the standard deviation of the population.

In this case, x = 7, mu = 10, and sigma = 2. So the z-score is:

z = (7 - 10) / 2 = -1.5

We can look up the probability of a z-score less than -1.5 in a standard normal distribution table or use a calculator. The probability is approximately 0.0668 or 6.68%.

Therefore, the probability that the length of the croaker fish is less than 7 inches is 0.0668 or 6.68%.

b) To find the probability that the length of the fish is between 7 and 15 inches, we need to calculate the z-scores of 7 inches and 15 inches using the same formula as above:

z1 = (7 - 10) / 2 = -1.5

z2 = (15 - 10) / 2 = 2.5

We can look up the probability of a z-score between -1.5 and 2.5 in a standard normal distribution table or use a calculator. The probability is approximately 0.9332 or 93.32%.

Therefore, the probability that the length of the fish is between 7 and 15 inches is 0.9332 or 93.32%.

Maker spent $48,000 on a brand-new rolling press. Its value has decreased at a pace of 18% per two years. Seven years after the initial purchase, the rolling press is worth $18,687.53.

We can solve this problem by using the formula for exponential decay:

V = [tex]P * (1 - r)^n[/tex]

where V is the value of the rolling press after n years, P is the initial purchase price, r is the depreciation rate per period, and n is the number of periods.

In this case, we have:

P = $48,000 (the initial purchase price)

r = 18% every 2 years = 0.09 per year (since there are 2 two-year periods in 1 year)

n = 7 years (the number of years that have passed)

These values are entered into the formula to produce the following results:

V = [tex]$48,000 * (1 - 0.09)^7[/tex]

V ≈ $18,687.53

The vertex of the parabola is (h, k) = (3, -8), The graph in red has vertex (3, -8), thus, the red parabola is correct.

A quadratic function is a polynomial function of the form f(x) = ax² + bx + c, where a, b, and c are constants and a is not equal to 0.

We know that the standard form of the parabola is y=ax²+bx+c. Thus, the vertex form of a parabola is y = a(x-h)² + k, and the vertex is given by (h, k)

here,  y = −(x − (3))² (−8) is already in vertex form.
