Emily measures a prize wheel at a carnival and calculates that it has an area of 3.14 square feet. What is the prize wheel's cir
Marizza181 [45]

The circumference of wheel is 6.28 feet.

Step-by-step explanation:

Given,

Area of prize wheel = 3.14 square feet

Area = πr²

3.14 = 3.14(r)^2

Dividing both sides by 3.14

\frac{3.14}{3.14} = \frac{3.14(r)^2}{3.14}\\1=r^2\\r^2=1\\r=1

Circumference = 2πr

Circumference of prize wheel = 2*3.14*1\\

Circumference of prize wheel = 6.28 feet

The circumference of wheel is 6.28 feet.

Tim is painting his storage shed. He buys 4 gallons of white paint, and 3 gallons of blue paint. Each gallon of white paint cost
Alchen [17]

$128.49

<h3>Further explanation</h3>

<u>Given:</u>

  • Tim is painting his storage shed.
  • He buys 4 gallons of white paint and 3 gallons of blue paint.
  • Each gallon of white paint costs $15.72.
  • Each gallon of blue pain costs $21.87.

<u>Question: </u>

How much will Tim spend on the paint?

<u>The Process:</u>

We first calculate the total cost spent on each color of the paint.

Total costs of white paint  \boxed{ \ = 4 \ gallons \times \frac{ \$15.72}{1 \ gallon} = \boxed{ \ \$62.88 \ } \ }

Total costs of blue paint  \boxed{ \ = 3 \ gallons \times \frac{ \$21.87}{1 \ gallon} = \boxed{ \ \$65.61 \ } \ }

The overall cost of painting is \boxed{ \ \$62.88 + \$65.61 = \boxed{ \ \$128.49 \ } \ }

<u>Quick Steps:</u>

Total costs  \boxed{ \ = \bigg(4 \ gallons \times \frac{ \$15.72}{1 \ gallon} \bigg) + \bigg(3 \ gallons \times \frac{ \$21.87}{1 \ gallon} \bigg) \ }

\boxed{ \ \$62.88 + \$65.61 = \boxed{ \ \$128.49 \ } \ }

Therefore, Tim will spend the total costs to paint his storage shed as much $128.49.

How do you solve this
Katen [24]

Answer:

4x^-4/9y^6

Step-by-step explanation:

If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:

(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2

When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4

Going through:

2^2*(x^-2)^2 / 3^2*(y^3)^2

=4*x^-4 / 9*y^6

=4x^-4/9y^6

Hope this helped!
