german

Answer:

Final answer is approx $\cos\left(H\right)=0.4235$ .

Step-by-step explanation:

using given information from the attached picture, we need to find the value of cos(H) so let's apply the formula of cosine.

$\cos\left(\theta\right)=\frac{adjacent}{hypotenuse}$

$\cos\left(H\right)=\frac{GH}{FH}$

$\cos\left(H\right)=\frac{36}{85}$

$\cos\left(H\right)=0.423529411765$

Hence final answer is approx $\cos\left(H\right)=0.4235$ .

A car rental agency rents cars for $26.20 per day plus $0.35 per mile driven. Your travel budget is $200. Write an inequality th

laila [671]

For this case we have to:

x: Represents the number of miles that can be traveled in a day

We have that the cost of daily car rental is given by the following expression:

$26.20 + 0.35x$

If the person has a budget of $200 then we have to:

$26.20+0.35x\leq200\\0.35x\leq200-26.20\\0.35x\leq173.8\\x\leq\frac{173.8}{0.35}\\x\leq496.57$

Thus, you can travel 496 miles in one day.

Answer:

$26.20 + 0.35x \leq200$
