Answer:

Step-by-step explanation:

Use .25 to represent the 1/4 of a mile.

Since it is a given radius around the boulder, we would treat it as such and find the area of the circle around the boulder.

To do this, you do .25² * 3.14

.0625 * 3.14 = .19625

15/.19625 = 76 and some change, but you need to round down to 76

Answer is 76.

A telemarketer earns $150 a week plus $2 for each call that results in sale. Last week she earned a total of $204. How many of h

cluponka [151]

Answer:

27 calls

Step-by-step explanation:

Let T(x) represent total sales.

Then T(x) = $150 + ($2/call)x, where x is the number of calls made.

If T(x) = $204, we can solve for x, the number of calls made:

$204 = $150 + ($2/call)x, or

$ 54

----------- = 27 calls

Josiah traveled 79.5 miles on 3 gallons of gasoline. At this rate, how many gallons of gasoline would he need to travel 265 mile

BigorU [14]

Josiah would need 10 gallons to travel 265 miles.

First we divide 79.5 by 3 to find out how many gallons are needed for one mile.

79.5/3=26.5

For one mile we need 26.5 gallons of gas.

Now we will divide 265 by 26.5 to find the answer to the problem.

265/26.5=10

Josiah will need 10 gallons of gas to travel 265 miles
