Hi There,
----------------------------------------
We Know:
Total Perimeter = 450 feet
Length is 2 times the width.
----------------------------------------
Solution:
Length = 150
Width = 75
75 x 2 = 150
150 + 150 + 75 + 75 = 450
----------------------------------------
Answer:
Length = 150 feet.
Width = 75 feet.
----------------------------------------
Hope This Helps :)
Answer:
611.08
Be sure to treat the two shapes as completely different figures, then add their totals together
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
This is not a function because -2 and 15 are being repeated in the domain and range.
