Part A
1) If 1 lap =1/4 mi, the to find length 8 laps we need 
8*1/4=2 mi 
2) 1 mi is 5280 ft, so
2 mi =2*5280=10560 ft

Part B
1) He already run 2 mi. He wants to run 10 mi.
Then he needs run 10-2=8 mi. He needs to run 8 more mi.

1 lap ----1/4 mi
x laps ---8 mi

x=(1*8):1/4=8*4=32 loops
So, Roger needs to run 32 more loops.

A: 8 x 1/4 = 2, so Roger ran 2 miles. 5280 x 2 = 10560, so Roger ran 10560 feet.
B. Roger already ran 2 miles, so he needs to run 8 more miles to reach his goal. 1 lap = 1/4 mile, so divide 1/4 from 8 to get 32. Roger needs to run 32 more laps this week.

Ad libitum [116K]

Answer:

1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:

120 = 20 + 50t

2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.

t ≤ (120 - 20)/50

t ≤ 2 hours

Thus, the domain would be 0 < t ≤ 2.

N76 [4]

Hello from MrBillDoesMath!

Answer:

x >= 7

Discussion:

x + 5 >= 12                  =>  add -5 to both sides

x + 5 -5 >= 12 - 5        => as 5-5 = 0 and 12 =5 = 7

x >= 7

Thank you,

MrB
