Method One:
Step One: Figure out how long the width is, witch is 19 feet.
Step Two: Multiply 2*19 and 3*11 because it is 2 times as long and three times as wide
Step Three: Add 38+33
The new perimeter will be 71 feet.
Answer:
$0.65
Step-by-step explanation:
x=cost of washcloth
x+1.20=cost of towel
Now,
x+x+1.20=2.50
2x=1.30
x=0.65
So, cost of washcloth is $0.65
Answer:
The perimeter is found by multiply multiplying the length by 2 and adding it to the width multiplied by 2.
Perimeter = 2L +2W
The length is given as twice the width which would be written as 2W
Now you have P = 2(2w) +2w
The perimeter is given as 52 cm:
51 = 2(2w) +2W
Simplify:
51 = 4w +2w
51 = 6w
Divide both sides by 6:
w = 51/6
w = 8.5
The width is 8.5 cm
The length is 2w = 2*8.5 = 17 cm
Answer:
81mm
Step-by-step explanation:
the number of steps is small enough that we can simply list out each step
let the time elapsed be t and the original length be L ( = 1 mm)
when t = 0, L = 1mm
when t = 10, L = 3mm
when t = 20, L = 3 x 3 = 9mm
when t = 30, L = 9 x 3 = 27mm
when t = 40, L = 27 x 3 = 81mm
