You need to ride an average of at least 35 miles per day for five consecutive days to qualify for a cross country biking expedition. The
distances (in miles) of your rides in the first four days are 45, 33, 27, and
26. What distances on the fifth day will allow you to qualify for the
competition? You just need to give the inequality for the correct solution.

44 miles

Step-by-step explanation:

Given that:

Required average = 35 miles

The distances (in miles) of your rides in the first four days are 45, 33, 27, and 26

Distance needed on the 5th day to qualify:

Let 5th distance required = x

Take the Average of all 5 distances:

(45 + 33 + 27 + 26 + x) / 5 = 35

(131 + x) / 5 = 35

131 + x = 35 * 5

131 + x = 175

x = 175 - 131

x = 44

  A  f(n)=8(0.75)^n

Step-by-step explanation:

After the first bounce, the height is 8·0.75 = 6 ft. Each subsequent bounce multiplies the previous height by 0.75, so the height after n bounces is ...

  f(n) = 8·0.75^n . . . . matches choice A
