How to solve the question step by step

Length = L

New length = L+0.1L= 1.1 L

Width = W

New width = W - (W/100)p= W-pW/100= (100W-pW)/100=W(100-p)/100

Area =A = LW

New area = A - 0.12A = 0.88A

New area = new width*new length = 1.1L*W(100-p)/100 = 1.1A(100-p)/100

New area = 0.88A

New area = 1.1A(100-p)/100

1.1A(100-p)/100 = 0.88A

1.1(100-p)/100 = 0.88

1.1(100 - p) = 88

100 - p = 80

p = 20

Answer C) 20.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
