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 :))

Answer:
12.5 percent increase
Step-by-step explanation:
so we know from 48 oz to 54 oz, the amount increases by 6 oz
now we just have to determine 6 oz is what percentage of 48 oz
6 goes into 48 eight times
100 divided by 8 is 12.5
6 is 12.5 percent of 48
we can double-check this by multiplying 12.5 x 8 which equals 100 so that confirms its 12.5 percent
we get the 8 by seeing that 6 goes into 48 eight times.
if this is confusing comment below and i'll try to clarify

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to find EF
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
EF² + DF² = DE² ← substitute values
EF² + 12² = 18², that is
EF² + 144 = 324 ( subtract 144 from both sides )
EF² = 180 ( take the square root of both sides )
EF = 
→ A
