Answer:
100
Step-by-step explanation:
In this problem 10 represents 9% of a number. So, to find 90% you must multiply 10 by 10. You do this because 9% times 10 equals 90%; therefore, 100 must be 90%.
This can also be proven through cross multiplication. To set up a proportion put the percent over the number like, 
. Then cross multiply to get the equation, 
. Finally, divide both sides to get x=100.
Answer
2,6,10,14,18,22
Step-by-step explanation:
add 4
There are 3600 seconds in 1 hour.
Multiply feet per second by 3600 to get feet in 1 hour:
150 x 3600 = 540,000 feet in 1 hour.
1 mile = 5280 feet.
Divide feet per hour by 5280 to get miles per hour:
540,000 / 5280 = 102.27 miles per hour.
In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.
Answer: correct choice is B.
