A circular swimming pool has diameter 60 feet and is centered in a fenced-in square region measuring 80 feet by 80 feet. a concr
borishaifa [10]
If I read the question correctly, the information about the 80x80 fencing and the grass region are all irrelevant information. 

In order to find the area of the side walk we are going to use the formula A=pi(r^2) where r = the radius. The diameter of the pool is 60 feet and the the sidewalk is 5 feet bigger all around meaning we had 5 feet to both sides of this 60 feet giving you an overall diameter of 70 feet (or 60 + 5*2). To find the radius take half of the diameter. 70/2 = 35. 

Now we plug in 35 to the equation. A = Pi(35^2) = 1225pi. Leave your answer like this as we are not finished and will need to round at the end for an accurate answer. This is NOT the end, that number is the area of the sidewalk AND the pool.

The sidewalk is not a full circle, just a border so we now have to find the area of the actual pool and subtract it from this 1225pi for the sidewalk's area. Same formula, Area = pi(r^2). The diameter of the pool is 60 meaning the radius is 30 (or 60/2). Plug into the equation, pi(30^2) = 900pi.

Now do 1225pi - 900pi to get 325pi. Break out your calculator and hit the approximation button. 325pi is approximately 1021.018 if rounded to 3 decimal places.

The area of the 5-foot wide sidewalk encircling the pool is approximately 1021.018 square feet.

In her first five basketball games, Tara scored 10, 11, 15, 16, and 18 points. What is the mean absolute deviation for this set
Daniel [21]
Hello there, and thank you for posting your question here on brainly.

To find mean absolute deviation, (MAD) you have to add all the numbers together, and then divide by how much numbers are in the set.

So we have to do 10 + 11 + 15 + 16 + 18, and then divide by 5.

10 + 11 + 15 + 16 + 18 ===> 70

Now, divide by 5.

70 / 5 ===> 14

The mean absolute deviation is 14.

Hope this helped! ☺♥

Multiply or divide as indicated. x^-8 • x^-2
gladu [14]

ANSWER

\frac{1}{ {x}^{10} }

EXPLANATION

The given exponentiial expression is

{x}^{ - 8}  \bullet {x}^{ - 2}

We simplify using the rule:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We apply this property to get:

{x}^{ - 8}  \bullet {x}^{ - 2}  = {x}^{  - 8 + - 2}

We simplify to get;

{x}^{ - 8}  \bullet {x}^{ - 2}  = {x}^{  - 10}

We rewrite as a positive index to get;

{x}^{ - 8}  \bullet {x}^{ - 2}  =  \frac{1}{ {x}^{10} }
