Answer:
78
Step-by-step explanation:
Let's start by defining a few variables:
x=width of the floor
x+36= length of the floor
Since area = length x width, we can write the equation:
x(x+36)<2040 ft² (this is your mathematical sentence
Make a chart of the possible values:
x | x+36| Area
30 66 = 1980 fits
31 67 = 2077 *too big
So, all dimensions with length smaller than 30 and widths smaller than 66 fit the system.
x(x+36)=144? Let's try smallest numbers - width of 1 ft, length of 37 ft
1(37)=37 too small
3(39)=117 nope
4(40)=160 nope
So, no, 144 ft² is not a realistic answer.
Answer:
Length of arc between two cars = 7 feet (Approx.)
Step-by-step explanation:
Given:
Radius of carinal wheel = 18 feet
Number of car equal distance = 16
Find:
Length of arc between two cars
Computation:
Angle between two cars = 360 / 16
Angle between two cars = 22.5°
Length of arc = [θ/360][2πr]
Length of arc between two cars = [22.5/360][(2)(3.14)(18)]
Length of arc between two cars = [0.0625][(6.28)(18)]
Length of arc between two cars = [0.0625][113.04]
Length of arc between two cars = 7.0625
Length of arc between two cars = 7 feet (Approx.)
