Rom4ik [11]

X=number of females
47-x=number of males
# of males is 2*(number of females)-7:
47-x= 2x-7
add x to both sides:
47=3x-7
add 7 to both sides:
54=3x
divide both sides by 3:
x= 18 females
47-18= 29 males

Gala2k [10]

Answer:

193 in

Step-by-step explanation:

Volume of a triangular prism:

The volume of a triangular prism is the base area multiplied by the wedge, that is:

$V = A_bw$

The base area is one half times the triangle base times it's height, so:

$V = 0.5*b*h*w$

The wedge of cheese is 7 inches tall.

This means that $w = 7$

The base of the cheese is shaped like a triangle with a base of 11 and a height of 5 inches.

This means that $b = 11, h = 5$

Volume:

$V = 0.5*b*h*w = 0.5*11*5*7 = 192.5$

Rounding, approximately 193 in.
