Answer:
Step-by-step explanation:
If you want the surface area of a rectangular prism, then you'll use a formula resembling this:
A = 2(area of end) + 2(area of top) + 2 (area of side).
Example: suppose the dimensions of the prism are 3 in by 5 in by 8 in.
Then the total surface area is:
A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or
A = 30 + 96 + 80 sq in, or A = 206 sq in
Answer:
$0.5
Step-by-step explanation:
Given data
Cost of 5 pencils= $2.50
Required
The cost per pencil
The cost per pencil is
Cost of 5 pencils divided by 5
=2.5/5
=$0.5
This is the constant of proportionality
For any number of pencils x
The cost is
Cost =0.5x
Hence the cost of one pencil is $0.5
Answer:
A = 101 degrees
Step-by-step explanation:
ok so a traingle has a full degree of 180, and on here we have degress C and B but need to know A
all we have to do is add 24 and 55 which is 79 and then substarct 79 from 180 to know how much is A's degree....which is... 101 degrees YAY!
to make sure u add them all up : 24 + 55 + 101 = 180
