Write an algebraic expression for the perimeter of the swimming pool

1 answer:

6 0

Answer: I don't see that you have a diagram of the swimming pool or any given side measures but assuming it is a rectangle, the algebraic expression would be 2(L+W) where L is the length and W is the width.

Step-by-Step Explanation: So when you are finding the perimeter, you are finding the length of the space surrounding something. So you would add up the length of all its sides to find it. In a rectangle, opposite sides are equal, therefore the length will be equal to the side opposite to it and the width will also be equal to the side opposite to it. So if you were to write the expression like that, you would get L+L+W+W, which can be simplified to 2L+2W, or just 2(L+W).

TiliK225 [7]

Answer:

atleast 385

Step-by-step explanation:

Given that an electrical power company is looking to expand into a new market. Before they commit to supplying the new area with electricity, they would like know the mean daily power usage for homes there.

Population std deviation = $\sigma = 50$

Sample size = $n$

STd error of sample mean = $\frac{50}{\sqrt{n} }$

Margin of error for 95% would be Critical value ( std error)

Here since population std dev is known we can use Z critical value= 1.96

$1.96*\frac{50}{\sqrt{n} }19.6^2\\n>384.16$

Sample size should be atleast 385

3. 5 bananas cost $2. At this rate, how much do 4 bananas cost?

Annette [7]

Answer:

$1.60

Step-by-step explanation:

Write out a proportion.

5 bananas/$2 = 4 bananas/$x

Simplify the proportion, by cross multiplying.

2 times 4 equals 8, then divide 8 by 5, which will give you our variable x.

8/5 is the same as 1.60, so the cost of 4 bananas will cost $1.60.

Hope this helped,

Philip
