Answer:
C) 12/20
Step-by-step explanation:
Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).
So the probability is:
(10 + 4 − 2) / 20 = 12/20.
Answer:
width=4
length=18
Step-by-step explanation:
length-6=3width
length=3width+6
also:
perimeter of the rectangle=2(length+width)
44/2=width+length
22=width+length
now put the length we found in the 1st equation, in 22=width+length
=>22=width+3width+6
22-6=4width
width=4
now do the exact same thing with one of these equations:
22=width+length
length=3width+6
I'd do it with the 1st one:
22=4+length
22-4= length
length=18
Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
<u><em>The correct question is</em></u>
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

where
B is the area of the base
h is the height of the prism
<em>Find the area of the base B</em>
---> the base is a square
we have

substitute

Part 2) Find the surface area of the prism
The surface area of the prism is equal to

where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
<em>Find the perimeter of the base P</em>
<em></em>
<em></em>
substitute the values in the formula
