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.)
Each two digit number has two numbers (duh!). Let's allow the tens digit to be x and the units digit to be y. Tens digit is 3 less than the units digit: x = y-3 Original number is 6 more than 4 times the sum of the digits: 10x+y-6 = 4x + 4y This gives us simultaneous equations!First let's clear the mess: 1. x= y-32. 6x-3y=6 Substitute 1 into 2: 6(y-3) -3y =66y - 18 - 3y = 6
3y = 24y = 8 Our units digit is 8 Substitute y= 8 into 1. x = y - 3x = 5 Our tens digit is 5 Therefore, our number is 58
Answer:
66, 68, 70
Step-by-step explanation:
68 + 70 = 138
138 - 66 = 72
