A machine puts out 100 watts of power for every 1000 watts put into it. The efficiency of the machine is
1 answer:
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%

The values which completes the table regarding summer camp is option b which is a=15,b=7, c=5, d=10, e=12.
Given that there are 32 campers, 22 of them can swim, 20 play softball and 5 do not play softball or swim.
We have to find the values of a,b,c,d,e so that we can complete the table.
Table is a combination of rows and columns. In our case the third row and third column shows the total.
from the table we can write that 22+d=32-----------1
so d=32-22
=10
d=10
c+5=d-----------2
c=10-5=5
c=5
a+c=20------------------3
a+5=20
a=20-5
a=15
a+b=22--------------3
15+b=22
b=7
20+e=32----------4
e=32-22
e=10.
Hence the values which completes the table is a=15,b=7, c=5, d=10, e=12.
