Answer:
Formula: (x^2 -h) +(y^2 -k)=r^2
The number on the right side of the = is the radius of the circle squared.
(h,k) is the center of the circle.
Answer:
a = c - 3b/2
Step-by-step explanation:
2a + 3b - 3b = c - 3b
2a = c - 3b
2a/2 = c/2 - 3b/2
therefore your answer is a = c - 3b/2
Answer:
It will cost $512.73
Step-by-step explanation:
9 in by 6 in sandbox cost $228
i.e., 9*6 = 54 in²
54 in² cost $228
1 in² will cost $228/54
≈ $4.22
If the new dimension is 13 1/2 in by 9 in
then area will be 13 1/2*9
27*9/2 = 121.5 in²
The cost of 121.5 in² will be
121.5*4.22 = $512.73
Answer:
B. 8³ in. ²
Step-by-step explanation:
The sum of 4³*2³= 512
And the sum of 8³ = 512
Another way to do this if the numbers have the same exponent just multiply the numbers by each other to get the answer.
Example: 4³*2³
Multiply 4*2 = 8
Put the exponent 8³
Hope this helps ya!
