Well 120 is 1/3 of the square so the 9ft is 2/3 of the square so it is B
It’s 144
You do a^2 + b^2 = c^2
B is 42 and C is 150 since it’s the hypotenuse
You do it all out and get 22,500 - 1764
Then find the square root and end up with 144
Answer:
75.4
Step-by-step explanation:
A=2πrh+2πr2=2·π·2·4+2·π·22≈75.39822
Find the unit rate by dividing.
308/11 = 28
28*3 = 84
Answer: 84 miles in 3 hours
Answer:
Plug in for y the first equation, to get 3(2x-4)=2x, 6x-12=2x, subtract 2x from both sides and get 4x-12=0, add 12 to both sides to get 4x=12, divide both sides by 4 to get x=3 and plug that into the first equation to get y=2(3)-4, y=6-4=2 so x=3 and y=2
