Hey there,
2 hours = 15 pages
1 hour = 15 / 2
= 7.5 pages
15 pages = $40
1 page = $40 / 15
= $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
= $20
Hope this helps :))

The average fraction of the students in the two classes is 17/20.
<h3>What is a fraction?</h3>
A fraction is a ratio of two integers called the numerator and denominator.
Analysis:
sum of the fraction of both students in the two classes = 4/5 + 9/10 =
LCM of the denominators which are 5 and 10 is 10
so the sum of both fractions = 8/10 + 9/10 = 17/10
The average = 17/10 /2 = 17/10 x 2 = 17/20
In conclusion, the average of the fraction of students on both classes is 17/20.

Answer:
- 1/2
Step-by-step explanation:
turn 2/5 to have the same denominator as 10
2 ( 2 ) = 4
5 ( 2 ) = 10
4/10 - 9/10
= -5/10
simplify
-5/10 = -1/2

Answer:
Option D.The decrease in the value of the car, which is 8%
Step-by-step explanation:
we have a exponential function of the form
where
y is the value of the car
x is the time in years
a is the initial value
b is the base
r is the rate of decrease
b=1+r
In this problem we have
a=$24,000 initial value of the car
b=0.92
so
0.92=1+r
r=0.92-1=-0.08=-8%-----> is negative because is a rate of decrease
