Answer:

Step-by-step explanation:
The formula of a volume of a square pyramid:

a - base edge
h - height of a pyramid
We have H = 8in.
Substitute and solve for a:

Answer:
f(2) = 15.5
f(3) = 18
f(4) = 20.5
f(5) = 23
f(6) = 25.5
g(2) = 64
g(3) = 96
g(4) = 128
g(5) = 160
g(6) = 192
Step-by-step explanation:
plug it all in to the equations
.0625 is the answer. Hope this helped
Answer: y= 4 or y= -12
Step-by-step explanation:
Y²-8y+16=64.
Rearrange
Y²-8y+16-64=0
Y²-8y-48=0
(Y²+12y)-(4y-48)=0
Y(y+12)-4(y+12)=0
(Y-4)=0 or (y+12)=0
Y-4=0 or y+12=0
Y=4 or y=-12
Ratios don't have to be "per" something, while rates are "per" something.
Ratios compare 2 or more values, as well as rates.
