In 1998, Journeys sold 15 million pairs of Vans across the
U.S. In 2008, Journeys sold 45 million pairs of Vans. What
was the average rate of change in shoe sales for the store?

Answers

Answer:

3 million/year

Step-by-step explanation:

Average rate of change is the slope in same interval:

(45 million - 15 million)/(2008 - 1998) years=30 million / 10 years =3 million/year

Given:

In 1998, Journeys sold 15 million pairs of Vans.

In 2008, Journeys sold 45 million pairs of Vans.

To Find:

The average rate of change in show sales for the store.

Formula:

Final year : 2008

Initial year : 1998

Final sale : 45 million

Initial sale : 15 million

Average sales = Final sale - Initial sale / Final year - Initial year

Explanation:

Average sales = 45 million - 15 million / 2008 - 1998

Average sales = 30 million / 10 years

Average sales = 3 million / 1 year

Answer:

The average rate of change in show sales for the store is 3 million per year.

The dew point in degrees Fahrenheit can be calculated with the formula DP = T (100 - RH), where DP is
the dew point, T is the dry-bulb temperature, and RH is the relative humidity. Which of these is the equation
solved for RH?
RH = 100 -
(T-DP)
RH = 100 – 2 (DP-1)
RH = 100 – (DP-1)
RH = 100 – 25 (T-DP)

Answers

Answer:

Step-by-step explanation:

I took that same test and i didthe practice test. Believe me.

The equation that can be used to solve for RH is 25/9(DP-T) - 100

Given the formula for the dew point in degrees, Fahrenheit expressed as

DP = T - 9/25(100 - RH)

To solve for the value of RH, we will make RH the subject of the formula;

DP = T - 9/25(100 - RH)

Subtract T from both sides:

DP - T = 9/25(100 - RH)

Multiply both sides by 25

25(DP - T) = 9(100 - RH)

25(DP - T) = 900 - 9RH

25(DP - T) - 900 = 9RH

RH = 25/9(DP-T) - 100

Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100

Answers

Answer:

How many students run TRACK? 210

How many students play BASEBALL? 98

15*14= 210 and 7*14 = 98, 210 - 98 = 112

Answer:

There are 210 students who run track and 98 students who play baseball.

Step-by-step explanation:

15x= Students who run track

7x= Students who play baseball

15x - 7x = 112 (*combine like terms)

8x = 112 (*divide 112 by 8)

X = 14 (*now plug X into both equations stated earlier)

15x = 15 x 14 = 210 (Number of students who run track

7x = 7 x 14 = 98 (Number of students who play baseball)

<=> 4c = 70

<=> c = 70/4 = 35/2 = 17,5

CHECK THE ANSWER:

-9(c+7) = -13c+7
