A square measures 8 inches on each side. What is its area rounded off to the nearest square centimeter? (

Answers

Answer 1

Answer: The area of any rectangle is (length) x (width).
Your square is a rectangle, with length=width.

Using 1 inch = 2.54 centimeters, the square's area is

(8 x 2.54 cm) x (8 x 2.54 cm)

= (20.32 cm) x (20.32 cm) = 412.90⁺ cm²

Rounded to the nearest cm², it's 413 cm² .

Fred Johnson total insurance premium is 1,200. His employer pays 60% of the total premium. How much does Fred pay?

Answers

we can set up a proportion to find this

60 x
--- = ----
100 1200

then we cross multiply and divide to solve

60 times 1200 is 72000 divided by 100 is 720

now we know his employer pays 720 out of 1200

we subtract to find out how much he pays

1200-720 is 480

fred pays 480

Which of the following ordered pairs represents the solution to the system given below? x − 4y = 7
5x + 9y = 6

Answers

x − 4y = 7
5x + 9y = 6

5x − 20y = 35 //1st * 5
5x + 9y = 6

5x +9y - 5x + 20y = 6 - 35 //2nd - 1st
5x + 9y = 6

29y=-29
5x=6-9y

y=-1 //1st : 29
5x=6-9*(-1)

y=-1
x=15:5 //2nd : 5

y=-1
x=3

check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok

answer: (3;-1) represents the solution.

A gardener is planting two types of trees:Type A is three feet tall and grows at a rate of 15 inches per year.
Type B is four feet tall and grows at a rate of 10 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.

Answers

First convert the feet to inches:

3 feet= 36 in.; 4 feet=48 in.

Make an equation for each one:

Type A: h=36+15x

Type B: h=48+10x

Since the questions wants the heights to be equal, h=h so you can substitute so you have:

36+15x=48+10x

5x=12

x=2 2/5 years or 2.4 years
