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:23
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
a). 3y-6x=48
soln
or, 3xy=48
or, xy=48÷3
or, xy=32,,
b). y=3x+11
soln
or, y=13x
or, xy=13,,
(2b² +3b-10) / (b²-2b-8).
This fraction is invalid for all numbers rendering the denominator nil.
We notice that b²-2b-8 is a quadratic equation, so to factorize it let's find its roots:
b'= 4 and x" = -2. FOR THESE VALUES b= - 2 and b = 4 , render the fraction impossible
Answer:
I believe all are correct except for 4. (I would put "No correlation for 4)
Step-by-step explanation:
4 does not seem to be positive or negative rather it seems to be going straight across. It has no correlation.
