Answer:
3.5 miles
Step-by-step explanation:
We need to convert the fraction into decimal and add up both in decimal form and then make our estimate (closest to the exact answer).
1 and 1/8th means 1.SOMETHING
Dividing 1 by 8 would give us:
1/8 = 0.125
Hence, 1 1/8th = 1.125
Total miles = 2.57 + 1.125 = 3.695
THis is closes to 3.5 miles. THis is the answer.
Answer:
8% increase
Step-by-step explanation:
The length after the increase:
30 x 1.1 = 33cm
The width after the increase:
20 x 1.05 = 21cm
New perimeter:
2(33 + 21) = 108 cm^2
Old perimeter:
2(30 + 20) = 100 cm^2
Percentage increase of area:
108 / 100 = 1.08 = 8% increase
