Bases are squares with sides that measure 27 inches. The height is 12 inches.

Elan Coil [88]

Answer:

Part 1) $V=8,748\ in^3$

Part 2) $SA=2,754\ in^2$

Step-by-step explanation:

The correct question is

Find the volume and the surface area of a rectangular prism. Bases are squares with sides that measure 27 inches. The height is 12 inches.

Part 1) Find the volume of the prism

The volume of the prism is equal to

$V=Bh$

where

B is the area of the base

h is the height of the prism

Find the area of the base B

$B=27^2=729\ in^2$ ---> the base is a square

we have

$h=12\ in$

substitute

$V=(729)(12)=8,748\ in^3$

Part 2) Find the surface area of the prism

The surface area of the prism is equal to

$SA=2B+Ph$

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

Find the perimeter of the base P

$P=4(27)=108\ in$

substitute the values in the formula

$SA=2(729)+108(12)=2,754\ in^2$

A basketball player gets 2 free-throw shots when she is fouled by a player on the opposing team. She misses the first shot 40% o

yan [13]

The probability of missing the first shot is 40%. When she misses the first shot, the probability of missing the second shot is very, very low, only 5%. That means that the probability of missing both shots must be much smaller than the probability of missing the first shot.

40/100 * 5/100
0.4 * 0.05
= 0.02
= 2%

AURORKA [14]

Answer:

(x, y ) → (x + 11, y - 11 )

Step-by-step explanation:

Consider the point U and its image U'

U (- 9, 1 ) → U' (2, - 10 )

This represents a shift of 2 - (- 9) = 2 + 9 = + 11 → in the x- direction and

- 10 - 1 = - 11 ↓ in the y- direction

This can be shown in the translation rule

(x, y ) → (x + 11, y - 11 )
