The volume of a prism = area of the base * height
substitute:
640 = A * 8
base area=80 sq ft<span />
Answer:
79.95
Step-by-step explanation:
The first step is to rewrite the percentages into decimals so they can be added or subtracted easier. To turn a percentage into a decimal, remove the percent sign and move the decimal two spaces to the left (in other words, divide the number by 100).
12% becomes -0.12
8% becomes 0.08
Now, let's solve.
79.99 - 0.12 + 0.08
Evaluating 79.99 - 0.12, the equation becomes 79.87 + 0.08.
Evaluating 79.87 + 0.08, we get the final answer, 79.95.
Answer:
you would place the y-intercept at (0,-16). and then the coordinates would be (-4,0) and (2,0). and the graph would be facing up or positive .
Step-by-step explanation:
Answer:
n = 15
Step-by-step explanation:
This is a right triangle, and so the Pythagorean Theorem applies:
x^2 + 8^2 = 17^2
Solving for x^2: 17^2 - 8^2 = 289 - 64 = 225, and so x = 15.
n = 15
