the length of a rectangle is twice its width if the perimeter of the rectangle is 72 inches, find its area.

Answers

length = 2 x width

permiter = length x width x 2

perimeter = 72

72 ÷ 2 = 36

36 = 1 length and 1 width

(2 x width) + width = 36

width = x

2x + x = 36

3x = 36

x = 12

width = 12

length = 2 x width = 2 x 12 = 24

so

width = 12

length = 24

A wise man once said, "500 reduced by 4 times my age is 188." What is his age?

Answers

Answer:

125

Step-by-step explanation:

Answer:

He Is 78 Years Old.

Step-by-step explanation:

a = age

Solve for a in 500 - 4a = 188.

Simplify 500−4a=188.

500−4a=188

500+−4a=188

−4a+500=188

Subtract 500 from both sides.

−4a+500−500=188−500

-4a = -312

Divide both sides by -4.

[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]

a = 78

Answer:

He Is 78 Years Old.

What is the volume of the pyramid?
A. 624 cm3
B. 1,872 cm
C. 2, 808 cm
D. 4,212 cm
E. 8, 424 cm

Answers

Answer:

C. 2, 808 cm^3

Step-by-step explanation:

Given that

The base of the pyramid is 18 centimeters

And, the height of the pyramid is 26 centimeters

We need to find out the volume of the pyramid

As we know that

The volume of the pyramid is

= 1 ÷ 3 × base^2 × height

= 1 ÷3 × 18^2 × 26

= 2,808 centimeter^3

Hence, the correct option is c.

You flip a coin 50 times and get 26 tails. What is the experimental probability of flipping heads? Write your answer as a simplified fraction or a percentage.

Answers

Answer:

12/25

Step-by-step explanation:

If you got 26 tails, that means you got 50 - 26 or 24 heads. The experimental  probability can be represented by the desirable flips over the total number of flips. We are looking for heads, so the amount of heads is the amount of desirable flips, and the total is 50. From this, we get the fraction 24/50 which simplifies to 12/25.
