Answer:
r = 8
Step-by-step explanation:
r = C/2π = 16π/2π = 8
Answer:
The answer is below
Step-by-step explanation:
A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes
Solution:
Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.
Hence:
m + n = 30
60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.
The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time
The total distance ran (D) is:
D = 5.4(m/60) + b(n/60)
Answer:
B. <Q, <P, <R
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given the tables of H(t) an r(t), we want to find:
As stated, this is equivalent to:
Using the r(t) table, we can determine that:
Therefore:
And by using the H(t) table, we can determine that:
So, our answer is C.
I believe it’s 512$
1/4 of 512 is 128
128 * 4 = 512
