So in this case we just want to find the cubic root of this.
Cubic roots:
1: 1
2: 8
3: 27
4: 64
5: 125
6: 216
7: 343
8: 512
9: 729
So each side of the rectangular prism is 9 feet long.
Answer:
Step-by-step explanation:
If diameter is 6 then the radius is half of that or 3.
A = pi * r^2
A = pi * 3^2
A = 9pi ft^2
<h3>Answer:</h3>
a = -2
<h3>Explanation:</h3>
We want (5-a) to be 20 more than (6a-1). Then we can write ...
... (5-a) = (6a-1) +20
If we add (a-19) to both sides, we get
... -14 = 7a
... -2 = a . . . . . divide by 7

<em>Comment on the graph</em>
In the attached, we use the variable x, because this graphing calculator likes variables named x and y. We graph each expression and find the place where they both have the same value for the same value of x (the point of intersection). The value of the variable x at that point is -2, the solution we seek.
Answer:
H.28
Step-by-step explanation:
x : y = 3 : 4
=> 4x=3y => x=3y/4 -----(1)
(x+y)-9=40
=>x+y=49
using (1)
3y/4 +y= 49
y=28
substituting y in (1)
x=21
hence 28 is greater.
