Answer:
boiiiiiiiiiiiiiiiiiiiiii
Step-by-step explanation:
P=2L + 2W
88=2(3w) + 2w
88=6w +2w
88=8w
88/8=8w/8
11=w
If the perimeter is 88 and the width is 11 and the length is 3 times the width then the length is 33 and you plug those numbers into the original formula you get the starting perimeter of 88
P=2L + 2W
P=2(33) + 2(11)
P=66+22
P=88
68.54 of the surface of the water
Answer: Thomas spent .15 less
Step-by-step explanation:
Dan: 2.50/2=1.25
Thomas: 3.30/3=1.1
1.25-1.1=.15
"of" means to multiply. Let the unknown number be x.
59.5x = 2.38
Dividing both sides by 59.5,
x = 2.38/59.5
x = 0.04 or 4/100 = 2/50 = 1/25
