A rectangular parking lot has perimeter 250 feet. The length is
five feet more than twice the
width. Find the length and width
of the parking lot

length: 85

width: 40

Step-by-step explanation:

length: 2w + 5

width: w

perimeter = 2L + 2W

250 = 2(2w + 5) + 2w

250 = 4w + 10 + 2w

250 = 6w + 10

240 = 6w

w = 40

length: 2(40) + 5 = 85

width: 40

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
