Answer:
First find the area 72*63
A=4536
Then find the area 12*12
A=144
Then divide 4536/144
You would need 31.5 12 by 12in covers to decorate the rectangular region
As for the 6 by 6
You would need 126 album covers
As for the 9 by 9
You would need 51 covers
And as for the 15 by 15
You would need 20.6 covers
Let w be the number of women in the company.
We can write the ratio in dividing forms.
7/4 = 133/w
W = 76
So 76 + 133 is 209
So there r 209 workers in total
In point slope form: (y-y1)=m(x-x1) we have:
y+2=(2/5)(x-5) we want standard form ax+by=k when we finish so:
y+2=(2x-10)/5
5y+10=2x-10
5y+20=2x
2x-5y=20 now it is in standard form...
The answer to this question is true
