A car rental agency Advertise renting a car for $24.95 per day and $.33 per mile is Kevin rent the car for today how many whole
pychu [463]

Answer:

Kevin can drive 681 miles.

Step-by-step explanation:

In order to find the amount that he can drive in one day and only pay $250, we have to write an equation for the cost. Using x as the miles he drive, we can express the equation as:

y = .33x + 24.95

Now, we can plug in 250 for y.

250 = .33x + 24.95

225.05 = .33x

681.97 = x

Since we are looking for only whole miles, we have to round down to 681.

5 - 2 (a + 3b) / 2 = ? / ?
Semmy [17]

Answer:

(5-2a+6b)/2

Step-by-step explanation:

According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2

The center on a target has a diameter of 5 inches. The whole target has a diameter of 25 inches. The center of the target takes
Komok [63]
4%

To find the percentage, first find the area of both circles. The area formula is \pi  r^{2} . After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up: 

\frac{is}{of} =  \frac{percent}{100}


\frac{19.625}{490.625} =  \frac{percent}{100}


Cross multiplying and dividing by 490.625 will give a total of 4%.
