1.
area = L x w = 72
L = 2w
72 = 2w*w = 2w^2
divide by 2
36 = w^2
w = sqrt(36) = 6
l = 2*6 =12
perimeter = 2L +2W = 2*12 + 2*6 = 24+12 = 36
2.
sqrt(40)= 6.324555 cm ( round to 6.32 )
6.32 - 4 = 2.32 cm original length of a side
It is 1/3, add up the total number of kids, which is 30, the number of kids 6-8 is 10. 10/30 is equivalent to 1/3
F<span>irst you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30
or
</span>18/60=x
0.30=x
30
hope this helps!!!!
Answer:
(-2, 0.25)
(-1, 0.5)
(0, 1)
(1, 2)
(2, 4)
Those are the points. I just plugged each x value into the equation to get the y value. Hope it helps!
