First you have to set up your equation. 5x+80 and x+15.
Feet
_____
second
10 feet
________
16 second
equals
.625 feet per second
Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11
Volume of a pyramid is (L * w * h) / 3
L=10 and w=10
h can be found by using the Pythagorean theorem:
divide the base by 2 and we get 5. Then we have that the hypotenuse is 13 and the bottom of the right triangle we formed is 5. a= sqrt(c^2-b^2)
a=h=12
we plug these numbers into the formula for the volume of a pyramid and get:
400
I'm pretty sure this is correct.
