Answer:
Step-by-step explanation:
274.04/34=8.06(21)=169.26
1: (pi)5^2 = 78.54 then multiply that by 11 and you get 863.94
2: (pi)13^2= 530.93 then multiply that by 8 and you get 47247.44
3. (pi)18^2= 1017.88 then multiply that by 22 and you get 22393.36
Answer:
11.9 mm
Step-by-step explanation:
We can find d by applying the cosine rules.
d² = 21² + 27² - 2(21)(27) cos (25)
d² = 441 + 729 - 1027.75
d² = 142.25
d = √142.25
d = 11.9 mm (nearest tenth)
Divide them both ways.
250 / 8 = 31.25 miles per gallon
8 / 250 = 0.032 gallons per mile
Work out 9/25 of 100
To do this divide 100 by 25 = 4
Then multiply 4 by the numerator : 9*4 = 36
This means 36 people didn't like the book
So if there's 100 students altogether and 36 didn't like the book,
100-36 = 64
64 people liked the book
