Lol, bro, 15.68 is your solution
Answer:
B. angle 5
Step-by-step explanation:
Percentage of pages of a book read by Katie = 32%
Total number of pages of the book read by Katie = 80
Let us assume the number of pages that the book has = x
Then
(32/100) * x = 80
32x = 80 * 100
32x = 8000
x = 8000/32
= 250
So the book has a total of 250 pages in it.
Then
The number of pages that Katie still needs to read = 250 - 80
= 170
So Katie needs to read 170 more pages in the book.
15x = 500-50
15x = 450
x = 450/15
x =30
Thus, x is equal to 30.
Answer:
64.73 Watts
Step-by-step explanation:
We are given;
- Work done by the swimmer = 3,560 J
- Time, t = 55 seconds
We are required to calculate the power of the swimmer;
- We need to know that power is the rate of doing work
- That is, Power = Work done ÷ time
Therefore;
Power of the swimmer = 3,560 Joules ÷ 55 seconds
= 64.727 Watts
= 64.73 Watts
Thus, the power output of the swimmer is 64.73 watts
