Answer:
16, 18, 20
Step-by-step explanation:
We can estimate that the square of the middle integer will be about 1/3 of 980. Then the middle integer is about ...
√(980/3) ≈ 18.09
The integers are 16, 18, 20.
_____
<em>Check</em>
16^2 +18^2 +20^2 = 256 +324 +400 = 980
The answer is 254, but here is the walkthrough: First, I recommend trying to remember the steps of long division by using Daddy, mommy, sister, brother. Daddy for divide, mommy for multiply, sister for subtract, and brother for bring down. Then, simply follow the steps:
Answer:
I got 0.475 hope it helps!
ohh sorry didn't see the answer as a fraction part.
I tried it again and got 19/40 I hope you get it right!
Answer:
=>By the work energy relation:-
=>W = ∆KE
=>Ff.s = 1/2(M+m)v^2
=>µk x N x s = 1/2(M+m)v^2
=>µk x (M+m) x g x s = 1/2(M+m)v^2
=>v = √[2µkgs]
=>v = √[2 x 0.82 x 9.8 x 10.6]
=>v = 13.05 m/s
By the law of momentum conservation:-
=>Mu = (M+m)v
=>9230u = (9230+1250) x 13.05
=>u = 14.82 m/s
Step-by-step explanation:
2x+7+12y+1=180 and
2x+7=3x-7
x+6y=86 and
x=14
so x+6y=86 is 14+6y=86
6y=72
y=12
answer: x=14 and y=12
