Answer:
10%
Step-by-step explanation:
Machine out put power =100 watt
Machine input power=1000 watt
We have to find the efficiency of the machine.
We know that
Efficiency of machine=
Where O.p=Output power
I.p=Input power
By using the formula
Efficiency of machine=
Efficiency of machine (in percent)
10%
Hence, the efficiency of machine=10%
384 squared you are correct
This is because a cube has 6 faces
64x6=384
Answer:
So since the ball is at x=0 at the end.
We plug in it.
h(x) = 16 if you simplify it
Answer:
x = 4, 7
Step-by-step explanation:
We start off with the equation 
. from there, we can add 28 to both sides to get 
. From there, we have to factor the equation. In order to factor it, we have to ask ourselves what 2 numbers would add up to -11 and multiply to 28? In this case, the answer would be -7 and -4. So, we get the equation (x-7)(x-4) = 0. Then, we set each part of the equation = 0 to get the anwsers x = 4 and 7. Hope this helps!
Answer:
28
Explanation:
area of the cloth on the table: 6*4= 24
area of the extra cloth: 4*1=4
4+24=28
