The answer to 275 percent of 4 is 11
For the answer for number one you will multiply 3/4 and 9 and you will get 6.75 then you roun it to 6 for the answer.
For the answer for for number two postive 8 is to the right of zero so the opposite of 8 would be on the left of zero
3:c
Add 40 to both sides
20x = 60
Divide by 20
Answer: x = 3
What are you trying to ask
Answer:
(a) 4.00×10^7 m
(b) 5.10×10^14 m^2
(c) 1.083×10^21 m^3
Step-by-step explanation:
Put the given value of radius into the various formulas and do the arithmetic. Your scientific calculator can show you the results in scientific notation.
C = 2πr = 2π·6.37×10^6 m ≈ 4.00×10^7 m* . . . circumference
A = 4πr^2 = 4π(6.37×10^6 m)^2 ≈ 5.10×10^14 m^2 . . . area
V = (4/3)πr^3 = (4/3)π(6.37×10^6 m)^3 ≈ 1.083×10^21 m^3 . . . volume
_____
* An early definition of the meter was 10^-7 times the distance from the North Pole to the Equator as measured through Paris, France.
