Step-by-step explanation:
Volume of a sphere is
[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]
We are given the volume, v, and asked to find the radius, r.
Substitute 4500 ft^3 for v, solve for r.
[tex]4500 = \frac{4}{3} \times \pi \times {r}^{3} [/tex]
Multiply both sides by 3/4 to eliminate 4/3
[tex] \frac{3}{4} \times 4500 = \frac{4}{3} \times \pi \times {r}^{3} \times \frac{3}{4} [/tex]
[tex] \frac{13500}{4} = \pi \times {r}^{3} \: \\ then \: divide \: by \: \pi[/tex]
[tex] \frac{3375}{\pi} = {r}^{3 \: \: take \: the \: cubed \: root \: of \: both \: sides} [/tex]
[tex] \frac{ \sqrt[3]{ {15}^{3} } }{ \sqrt[3]{\pi} } = \sqrt[3]{r} [/tex]
[tex] \frac{15}{ \sqrt[3]{\pi} } = r [/tex]
That approximates to 10.27 ft^3

A car dealership pays $8,350 for a car. They markup the price by 17.4% to get the retail price. What is the retail price of the car at this dealership?
Answer:
I belive its $9,802.9
Step-by-step explanation:
$8,350 x 0.174 ( 17.4 ÷ 100)
= $1,452.9
$8,350 + $1,452.9 = $9,802.9
Determine which function has a greater change of rate.
Be sure to show work as well.
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change

Find the multiplier for 21.6% decay
Answer:
5pts
Step-by-step explanation:
The required multiplier for 21.6% decay is 78.4%.
Given that,
To find the multiplier for 21.6% decay
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay = 1 - r
Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%
Thus, the required multiplier for 21.6% decay is 78.4%.

This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the x-coordinate of one of the endpoints of the dilated segment
The x-coordinate of one of the endpoints of the dilated segment should be 8.
Calculation of x-coordinate:In the case when a coordinate point (x, y) should be dilated by a factor k, so the coordinate should be (kx, ky).Since the coordinate (4,1), so if this coordinate is dilated by a factor of 2 so the new coordinate points should be at (2(4), 2(1))Now
New point = (8, 2)

Find slope intercept form.
(M=1/2) (6,3)
Answer:
y = (1/2)x
Step-by-step explanation:
Start with that form: y = mx + b. Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:
3 = (1/2)(6) + b. Thus, b = 0 and the desired equation is y = (1/2)x.

The height and the slant height of a cone are 24 cm and 25 cm respectively. Find the volume of the cone.
Pls answer with steps :)
Answer:
volume =183.26 cm³
Step-by-step explanation:
volume of a cone = 1/3πrl
l is the slant height
using; l²=h²+r²
r²= l²-h²
r²= 25²-24²= 625-576 =49
r=√49=7cm
volume = 1/3πrl = 1/3 (π×7×25)= 1/3 ×549.78
=183.26 cm³
