The average
The data whose average is to be calculated are not given.
However, the formula to calculate the average is:
Assume the data is:
This means that the number of schools is 4
So:
<em>The average of the assumed data is 1238</em>
Answer:
Solution given:
the fractions Four-sevenths=4/7≈0.57
the fractions Five-ninths=5/9≈0.55
Since 0.55 is less than 0.57
<u>least=the fractions Five-ninths</u>
<u>greatest=the fractions Four-sevenths</u>
Set up a proportion:
The numerator represents fluid ounces of milk, and the denominator represents milligrams of calcium.
Simplify the first fraction to make multiplication easier:
Cross multiply the fractions:
Divide both sides by 135 to get x by itself:
2.1 fluid ounces of milk provide 72.5 milligrams of calcium.
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5
5 miles
