5 % 8,000 decreases to 400 by 5 %
Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
Y(smiths score)= x (Jones elementary score) - 30 (scored 30 less points than Jones)
Y=x-30
The next letter is w because it is the same distance form the middle as d
The answer is 25/28
Explanation:
First you’re gonna want to turn the mixed fractions into improper fractions
5/4 and 7/5
Now to divide fractions you flip the second fraction and then multiply so it will be
5/4x5/7 = 25/28
