Step-by-step explanation:
Answer:
7.5%
Step-by-step explanation:
Approximate distance = 180 miles
Actual distance = 167.5 miles
Percent error = { (approximate value - actual value) / actual value } × 100
= { (180 - 167.5) / 167.5 } × 100
= (12.5 / 167.5) × 100
= 0.075 × 100
= 7.5%
Answer:
length = 37 m
Step-by-step explanation:
let w be width then length = 2w - 7
The opposite sides of a rectangle are congruent
The perimeter is the sum of the 4 sides and is equal to 118 , then
w + w + 2w - 7 + 2w - 7 = 118 , that is
6w - 14 = 118 ( add 14 to both sides )
6w = 132 ( divide both sides by 6 )
w = 22
Then
length = 2w - 7 = 2(22) - 7 = 44 - 7 = 37 m
