Molly played an online game three times. Her scores were 5.5, -3.6, and 12.8. What was her average score for three games?

Ivahew [28]

In order to find the solution you must calculate the mean, or the average by adding the numbers together and dividing by how many numbers there are.

5.5 + -3.6 + 12.8 = 14.7

14.7 ÷ 3 = 4.9

4.9 is Molly's average score.

Hope this helps! <3

The area of a square game board is 144 sq. In. What's the length of the sides of the board?

Black_prince [1.1K]

So we want to know what is the lenght of the sides of the board that has an area of A=144 in^2. Well, we know that the area of a square is A=a^2 where a is the side of a square. So the length of the side is square root of the area: sqrt(144)= 12. So the length of the game board is 12 inches.

Which of the following numbers have a value equal to -5

Keith_Richards [23]

We must find which of the following numbers has a value equal to -5:

$\frac{-5}{1},\frac{5}{1},\frac{10}{-2},\frac{-5}{-1},-\frac{5}{1},-\frac{-5}{1},-\frac{-5}{-1},-\frac{-10}{2}.$

To answer this question, we simplify each number:

$\begin{gathered} \frac{-5}{1}=-5 \\ \frac{5}{1}=5 \\ \frac{10}{-2}=\frac{5\cdot2}{-2}=\frac{5}{-1}=-5 \\ -\frac{5}{1}=-5 \\ -\frac{-5}{1}=-(-5)=5 \\ -\frac{-5}{-1}=-\frac{5}{1}=-5 \\ -\frac{-10}{2}=-\frac{-5\cdot2}{2}=-(-5)=5 \end{gathered}$

Answer

The numbers that are equal to -5 are:

$\begin{gathered} \frac{-5}{1} \\ \frac{10}{-2} \\ -\frac{5}{1} \\ -\frac{-5}{-1} \end{gathered}$
