First we need to find a common denominator

$\frac{2}{10}$ = $\frac{20}{100}$
now we can add them

$\frac{20}{100}$ + $\frac{9}{100}$ = $\frac{29}{100}$

Sarah ran 2 miles and Jaime ran 15, 840 feet. How many miles did they run together? (The conversion factor is 5280 feet/mile.)

Korvikt [17]

Answer:

C. 5 miles

Step-by-step explanation:

Since we need to find how many miles they ran together, let us convert feet to miles. Sarah's length is already in miles so we'll leave it that way.

Jaime ran 15840 feet. We are given how many feet are there in one mile (5280), so we need to find how many miles are there in 15840 feet.

x = 15840 / 5280 = 3 miles.

So, Jaime ran 3 miles and Sarah ran 2 miles.

That means that together they ran 3 + 2 = 5 miles.

What is the mean of 72,73,86,59,75,58,50,55

Rashid [163]

<h3><u>MEAN</u></h3>

Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.

<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>

The first thing you need to do is add all the numbers. Add:

$72+73+86+59+75+58+50+55 = \bf 528$

Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.

Divide:

$528 \div 8 = \bf 66$

The mean is 66
