don't know if this is actually the answers but:

1.) V=4/3pi r^3

3V= 4pi r^3

3V/4pi = r^3

3√3V/4 pi = 3√r^3

Answer: r = 3√3V/4pi

2.) Answer: 1/4V - 532 = 4/3pi 22^3

Solve the system using substitution. 2x + 2y = 30 y - 4x = 0 ( _ , _ )

Kay [80]

Answer:

x = 3

y= 12

Step-by-step explanation:

2x + 2y = 30

y - 4x = 0 /*2

2x + 2y = 30

2y - 8x = 0

-----------------

10x = 30

x = 3

y= 12

What is the measure of EG?

IrinaVladis [17]

The first thing you should know in this case is that a circumference has a total measure in 360 degrees.
We have then that the formula to find EG in this case is:
EG + GF + FE = 360
We cleared EG:
EG = 360-GF-FE
We substitute the values:
EG = 360-83-66
EG = 211
Answer
EG = 211 degrees.

Calculate the alope of the line using two different pairs of points

ycow [4]

Answer:

The slope of the line between two points (-1, 2) and (-2, -4) will be:

$m=6$

Step-by-step explanation:

Considering the points

(-1, 2)

(-2, -4)

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-4\right)$

$m=\frac{-4-2}{-2-\left(-1\right)}$

$m=6$

So, the slope of the line between two points (-1, 2) and (-2, -4) will be:

$m=6$

The sides of a triangle are in the extended ratio 2 colon 6 colon 7. If the perimeter of the triangle is 45 inches, then what is

allsm [11]

Ratio : 2:6:7....for a total of 15. This means that one side is 2/15 of the total perimeter, one side is 6/15 of the total perimeter and one side is 7/15 of the total perimeter.

and if the total perimeter is 45 inches...
2/15 * 45 = 90/15 = 6 inches
6/15 * 45 = 270/15 = 18 inches
7/15 * 45 = 315/15 = 21 inches

and the shortest side is gonna be 6 inches <==
