Answer: 21
Step-by-step explanation:
we have two simple equations:
1) 70=100%
2) x=30%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
70/x=100%/30%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 30% of 70
70/x=100/30
(70/x)*x=(100/30)*x - we multiply both sides of the equation by
70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
70/3.33333333333=x
The fore, the answer is 21

Step-by-step explanation:
Hello
The sphere volume is:
(4/3)*Pi*r^3
then
36 = (4/3)*Pi*r^3
36/[(4/3)*Pi] = r^3
8,5 = r^3
r = 3

Answer:
Step-by-step explanation:
<h3>Given </h3>
<u>Function f, with </u>
<h3>To find</h3>
<h3>Solution</h3>
<u>Slope-intercept formula</u>
- f(x) = mx + b
- f(0) = -9 means y-intercept b = -9, and the slope is m = - 8
<u>So the function is</u>
