It is estimated that the annual cost of driving a certain new car is given by the formula C = 0.37m + 2600 where m represents th

arsen [322]

Answer:

12000-14000 (in miles)

Step-by-step explanation:

We are given that the annual cost of driving a certain car is given by the formula

$C=0.37m+2600$

Where m=Represents the number of miles driven per year

C=Cost in dollars

We have to find the range of miles that Jane can drive her new car.

Range of budgets=$7040-$7780

Substitute C=$7040 in the given formula

$7040=0.37m+2600$

$7040-2600=0.37m$

$4440=0.37m$

$m=\frac{4440}{0.37}$

$m=12000$

Substitute C=$7780 in the given formula

$7780=0.37m+2600$

$7780-2600=0.37m$

$5180=0.37m$

$m=\frac{5180}{0.37}=14000$

The range of miles that Jane can drive her new car=12000-14000

Pumps A, B, and C operate at their respective constant rates. Pumps A and B, operating simultaneously, can fill a certain tank i

jeka94

Let $a,b,c$ be the time it takes for pumps A, B, and C (respectively) to fill 1 tank. Then

$\begin{cases}\dfrac1a+\dfrac1b=\dfrac1{\frac65}=\dfrac56\\\\\dfrac1a+\dfrac1c=\dfrac1{\frac32}=\dfrac23\\\\\dfrac1b+\dfrac1c=\dfrac12\end{cases}$

Now,

$\left(\dfrac1a+\dfrac1b\right)-\left(\dfrac1a+\dfrac1c\right)=\dfrac56-\dfrac23\implies\dfrac1b-\dfrac1c=\dfrac16$

Then

$\left(\dfrac1b+\dfrac1c\right)+\left(\dfrac1b-\dfrac1c\right)=\dfrac12+\dfrac16\implies\dfrac2b=\dfrac23\implies b=3$

This means

$\dfrac1a+\dfrac13=\dfrac56\implies\dfrac1a=\dfrac12\implies a=2$

and

$\dfrac13+\dfrac1c=\dfrac12\implies\dfrac1c=\dfrac16\implies c=6$

Working together, all 3 pumps would operate at a rate of

$\dfrac1a+\dfrac1b+\dfrac1c=1$

or 1 tank in 1 hour, so the answer is D.
