1. A circular swimming pool has a diameter of 60 feet, and is surrounded by a concrete sidewalk that is 5 feet wide. What is the

Ivenika [448]

We first calculate the area of the entire pool and the side walk.

Given that the pool has a diameter of 60 feet and that the side walk surrounds the pool with a width of 5 feet. This means that the diameter of the entire pool and the side walk is 60 + 5 + 5 = 70 feet and the radius is 70 / 2 = 35 feet

Thus the area of the entire pool and the side walk is obtained as follows:

$Area=\pi r^2 \\ \\ =\pi(35)^2=1,225\pi\ square\ feet$

Given that the pool has a diameter of 60 feet, this means that the radius of the pool is 30 feet.

Thus the area of the pool is given by:

$Area_{pool}=\pi r^2 \\ \\ =\pi(30)^2=900\pi\ square\ feet$

Therefore, the area of the sidewark is the area of the entire pool and side walk minus the area of the pool, this is given by:

$Area_{side walk}=1,225\pi-900\pi \\ \\ =325\pi=1,021 \ square\ feet.$

Angie and Kenny play online video games. Angie buys 1 software package and 2 months of game play. Kenny buys 2 software packages

fgiga [73]

Answer:

The cost of one month of game play is $16

Step-by-step explanation:

* Lets change the information in the problem to equation and solve it

- Angie and Kenny play online video games

- Angie buys 1 software package and 2 months of game play

- Kenny buys 2 software packages and 5 months of game play

- Each software package costs $25

- Their total cost is $187

- We need to find the cost of one month of game play

* Lets find the cost of Angie buying and the cost of Kenny buying

- Assume that the cost of one month of game play is $x

∵ The cost of each software package is $25

∵ The cost of each month of game play is $x

∵ Angie buys 1 software package and 2 months of game play

∴ The cost of Angie buying = 25 + 2x

∵ Kenny buys 2 software packages and 5 months of game play

∴ The cost of Kenny buying = 2(25) + 5x = 50 + 5x

- The total cost is the sum of the costs of Angie buying and

Kenny buying

∵ The total cost is $187

∴ 25 + 2x + 50 + 5x = 187

- Add like terms

∴ 7x + 75 = 187

- Subtract 75 from both sides

∴ 7x = 112

- Divide both sides by 7

∴ x = 16

∵ x represents the cost of one month of game play

∴ The cost of one month of game play is $16
