An Uber driver carries riders to and from a local airport and a neighboring suburb. Due to traffic and the time of day the drive

r works, the trip to the airport takes 60 minutes longer than the trip to the suburb. The car’s average speed in traffic is 30 miles per hour. Without traffic, the car travels 15 miles per hour. The equation can be used to determine how many miles apart the two locations are shown. What is the value of m, the distances between the two locations?
A) 0.5 miles
B) 22.5 miles
C) 30 miles
D) 90 miles

Answer: Choice B) 22.5 miles

--------------------------------------------
--------------------------------------------

To find that answer, we simply solve for m

m/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1) ... multiply both sides by the LCD to clear out fractions
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2 <--- answer as a fraction
m = 22.5 <--- answer in decimal form

Use a calculator or long division to convert from fraction to decimal form.

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

3x+8y=55 -----> equation A

x+y=15

x=15-y -----> equation B

Substitute equation B in equation A

3[15-y]+8y=55

45-3y+8y=55

5y=55-45

5y=10

y=2

Find the value of x

x=15-y

x=15-2=13

therefore

<u>the answer is</u>

the number of multiple choice question are 13

the number of free response question are 2

Step-by-step explanation:

The <u>2x</u> represents the length (x) being half of the width (68)

The <u>-18</u> represents the width (68) being 18 less than twice the length (2x)

nata0808 [166]

9514 1404 393

Answer:

  $13,916.24

Step-by-step explanation:

First, we need to find the value of the CD at maturity.

  A = P(1 +rt) . . . . simple interest rate r for t years

  A = $2500(1 +0.085·3) = $2500×1.255 = $3137.50

__

Now, we can find the value of the account with compound interest.

  A = P(1 +r)^t . . . . . rate r compounded annually for t years

  A = $3137.50 × 1.18^9 = $13,916.24

The mutual fund was worth $13,916.24 after 9 years.

Answer:

angle 9 measures 105 degrees

Step-by-step explanation:

measure of angle 8 is congruent to measure of angle 11 (alternate-interior angles are congruent)

measure of angle 11 is congruent to measure of angle 9 (corresponding angles are congruent)

therefore, measure of angle 8 = measure of angle 9
