Answer:

76

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.

Answer:

x = 13

a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\

Take the square root of both sides

\sqrt{169} = \sqrt{c^2} \\13 = c

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va
Setler79 [48]

Answer:

A)  \frac{x}{8} gallons

B)  Distance between Town A and Town B is 48y  miles


Step-by-step explanation:

A)

We know, number of gallons = \frac{DistanceTravelled}{MilesPerGallon}

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = \frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}


B)

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y
