The volume V of a sphere with radius R is given by formula V=4/3 x 3.14 x r^3
Olin [163]
36(3.14) = 4/3 x 3.14 x r^3
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3

Check: 3^3(\pi)(4/3) = 27(3.14)(4/3) = 113.04

What is the slope of a line that is parallel to the line y=-1/5?
Hitman42 [59]

Answer:

slope = 0

Step-by-step explanation:

y = - \frac{1}{5} is the equation of a horizontal line parallel to the x- axis.

Since it is parallel to the x- axis the slope = 0

Thus any line parallel to it will have a slope = 0

What is the solution to this system?<br> X = 7 - 2y<br> 2x + y = 5<br> LE
Umnica [9.8K]

Answer:

y= 3

Step-by-step explanation:

1. plug in 7 - 2y for X in 2x = y = 5   it would look like this  2(7-2y) = y= 5

2. distribute the 2 with what is in the parenthesis. remember PEMDAS!! it would be 14 - 4y + y = 5

3. get the y alone. to do this subtract 14 from both sides. you will have

-4y + y = -9

4. combine the Y. you will get -3y = -9 (remember there is a 1 in front of alone variables that is how i got - 3)

5. divide to get the Y alone. that will be -9/-3 which is 3

your final answer: Y= 3

hope this helped :)
