Answer= 40%
40% of call are for air conditioners
1/5 of calls are for heaters
First, lets convert 1/5 into a decimal, and then a percent value.
1/5=0.20=20%
20% of calls are for heaters
100% represents the amount of service calls Mike receives.
100%-40%-20%=
100%-60%=40%
40% of the service calls Mike receives are other calls.
A'B'C' is larger than ABC, so the scale factor would be a whole number, scale factor of 2.
A'B'C'is also a morrir image of ABC, notice on ABC A is on the left and B is on the right, but on A'B'C', B" is on the left and A' is on the right.
This means it was reflected across the Y axis.
The first answer is the correct one.
You have to say what each of these costs per pound.
2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
Ab+12b^{2}-6 . The first one
