A function is a mapping from a set A to a set B, If, for all a1,a2 in A, where a1=a2, a1 and a2 get mapped to the same b in B
a)
Dimensions: 7.5m x 4.5m
Cost , x= $14.17/m^2.
The area of the rectangular room can be calculated as,

Now, the cost of carpeting the rectangular room is,

Therefore, the cost of carpeting the room with dimensions 7.5m x 4.5m is $478.24.
b)
Dimensions: 17 yd. x 12 yd.
Cost, x= $25/yd^2.
The area of the rectangular room can be calculated as,

Now, the cost of carpeting the rectangular room is,

Therefore, the cost of carpeting the room with dimensions 17 yd. x 12 yd is $5100.
Answer:
B. 4/8 = 5/10 = 1/2
Step-by-step explanation:
I calculated it logically
Don't sweat it. It looks complex but i will try to help explain it.
First all this equation ids saying is 8 times a number k divided by 3=32
So,First we get rid of the three.So it says divide by three so we do the opposite operation. So.So 32*3=96
Now we have 8k=96
So our goal is to get x by it self so we divide by 8 because we need to do do the opposite operation.
We get x=12
Answer:
136
Step-by-step explanation:
Take 68 x 2 since the side lengths are equal.
