Answer:
74-27q
Step-by-step explanation:
8(10 - 6q) + 3(7q - 2)
use the distributive property to get rid of the parenthesis
(8*10) - (8*6q) + (3*7q) - (3*2)
80 - 48q + 21q - 6
combine like terms
(80 - 6) - 48q + 21q
74 - 27q :)
Answer:
The answer is 8 feet.
Step-by-step explanation:
Let x = height where the ladder hits the building
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24 feet
Let x = distance from wall:
x^2 + 20^2 = 25^2
x^2 + 400 = 625
x^2 = 225
x = 15 feet
Answer:
The correct answer is D because for example...
Step-by-step explanation:
If b squared minus 4ac is non-negative, so at 0 or greater, we have at least one real solution. If it's less than 0, if it's negative, we have no real solutions!
Hope I was able to help, and I hope you Have a good day! :)
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.
