Juan drove his car on a vacation trip. His odometer Read 1460.3 when he began and 1830.2 at the end. If he used 20 gallons of ga

Aleonysh [2.5K]

Answer:

Juan got 18.50 miles per gallon.

Step-by-step explanation:

We are given the following in the question:

Odometer in the beginning of trip = 1460.3 miles

Odometer at the end of trip = 1830.2

Gallons of gas used for trip = 20 gallons

Distance of trip =

= Odometer at the end of trip - Odometer in the beginning of trip

$=1830.2-1460.3\\=369.9\text{ miles}$

Thus, the trip was of 369.9 miles.

Miles per gallon =

$=\dfrac{\text{Distance cover in trip}}{\text{Gallons of gas used}}\\\\=\dfrac{369.9}{20}\\\\=18.495\approx 18.50\text{ miles per gallon}$

Thus, Juan got 18.50 miles per gallon.

If f(x) = x and g(x) = 2, what is (fºg)(x)?

ICE Princess25 [194]

Step-by-step explanation:

(fog)(x) = f[g(x)]

f(g(x))

f(x-2)

since f(x) = 1 / x

answer: 1/x-2

1/x-2 looks like 1/x but the asymptotes(dips in the graphs) will be at x = 2 since is undefined

In ΔQRS, the measure of ∠S=90°, the measure of ∠Q=54°, and RS = 26 feet. Find the length of QR to the nearest tenth of a foot.

anastassius [24]

You may use the law of sines, that states that in every triangle the ratio between a side and the sine of the opposite angle is constant.

So, in your case, we have

$\dfrac{QR}{\sin(\hat{S})}=\dfrac{RS}{\sin(\hat{Q})}$

We know that $\hat{S}$ is 90 degrees, so its sine is 1. Also, we know that RS=26. So, the equation becomes

$QR=\dfrac{26}{\sin(54)}$
