Answer:
h = 3.5 in
Step-by-step explanation:
The formula for the volume of a square pyramid is
V = (1/3)(area of base)(height).
Here the base area is (7 in)², or 49 in², and the volume is 171.5 in³.
Substituting these values into the formula above yields:
171.5 in³ = (49 in²)(h), so that
171.5 in³
h = ---------------- = 3.5 in
49 in²
Answer:
−0.171428571 or -6/35
Step-by-step explanation:
This is the Simplest form
We can use algebra.
So, what rate time 1.20 = .80
Let x = the rate (in a decimal form)
1.20x = .80
x = .6666666666
Now, we need to multiply by 100 to get a percentage.
66.66 The price is 66% of the regular price.
