To find out how many square feet of exterior carpet we will need for this hole, subtract the area of the two interior rectangles from the area of the full green rectangle.

Area of the full green rectangle

$A=12*4=48\ ft^{2}$

Area of the two interior rectangles

$A=3*2+1*2=8\ ft^{2}$

Find the area of outdoor carpet

$A=48-8=40\ ft^{2}$

For what values of b the relation R:{(b^2, 5), (5b, 6)} is not a function?

xenn [34]

Answer:

B=5,0.

Step-by-step explanation:

It's not that hard. It's just that it might throw you off a bit with the R and the other things. Functions if you don't remember are where the coordinates don't have the same x and y. So since the y1 and y2 are different then to make it not a function, you have to make x1 and x2. To make it that b would have to be = to 5 and 0.

Genrish500 [490]

Answer:

660

Step-by-step explanation:

First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660

Hope this helps!
