Abdul will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of and costs an additio
Dafna1 [17]

The question is missing some important details required to answer the question. I found a similar question, so I will answer using this details. If there is any differences in the details, you can still use my working by changing the value given:

Abdul will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an idditional $0.11 per mile driven. The second plan has an initial fee of $49 and costs an additional $0.07 per mile driven.

How many miles would Abdul need to drive for the two plans to cost the same?

Answer:

275 miles

Step-by-step explanation:

Let the distance travel be X

First plan:

Initial fee: 38

Per mile: 0.11

So the total cost is

C1 = 38 + 0.11X

Second plan:

Initial fee: 49

Per mile:0.07

So the total cost is

C2 = 49 + 0.07X

Since the question asked about when the total cost be the same, we can say that C1 = C2

C1 = C2

38 + 0.11X = 49 + 0.07X

0.11X - 0.07X = 49 - 38

0.04X = 11

X = 11/0.04 = 275

At 275 miles, the cost will be the same.

How do you solve these problems?
Fed [463]

Answer:

Step-by-step explanation:

Hello,

a. The area of region P is the area of the rectangle 1 * e minus the

\displaystyle \int\limits^0_1 {e^x} \, dx=[e^x]^{1}_{0}=e-1

So this is e - (e-1) = e - e + 1 = 1

b. The area of region P is the area of the rectangle 1 * e minus P and minus the

\displaystyle \int\limits^0_1 {e^{-x}} \, dx=[-e^{-x}]^{1}_{0}=-e^{-1}+1

So this is

e - 1 - (-e^{-1}+1) = e-1+e^{-1}-1=e+e^{-1}-2

This is around 1.08616127...

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

What is the value of x?
ryzh [129]

Answer:

Step-by-step explanation:

The top triangle is similar to the whole triangle because of AAA

Then we know that the corresponding sides are similar

9/81=(3x-20)/(3x-20+56)

1/9=(3x-20)/(3x+36)

cross multiply

9(3x-20)=3x+36

27x-180=3x+36

24x=216

x=9
