There’s a problem with chair B. In order to fix it, the mechanics need to know the angle formed at the center of the ferris whee

dybincka [34]

Answer:

60 degrees

Step-by-step explanation:

The wheel is a circunference, so it has a total of 360 degrees. As we have 12 chairs evenly spaced, this 360 degrees will also be divided evenly, so the angle between each pair of chairs is equal to 360 / 12 = 30 degrees.

As we want the angle between chairs B and D, we have two spaces between chairs (the space between B and C and the space between C and D), so the angle is 2 * 30 = 60 degrees

Determine operating cost per mile. Choose the right answer.

SVETLANKA909090 [29]

Answer: $0.1428/mi or about 14 cents per mile

Steps:

While the cost of car = $5,000.00 is not an operating cost, the annual decrease of value is. So, given that the market value after 1 year = $3,800, the value loss is 5000-3800=$1200 for the year.

Add cost of gas and oil = $750.00, Repairs/Maintenance = $250.00, Insurance = $300.00, to get $2500 total operating cost.

The cost per mile is $2500/17500 miles = $0.1428/mi or about 14 cents per mile

The length of a rectangle is 2 Inches less than three times its width, and its perimeter is 36 Inches. Find the width of the

elixir [45]

Answer: Width = 5 inches

Concept:

Here, we need to know the idea of the perimeter.

A perimeter is a path that encompasses/surrounds/outlines a shape.

Perimeter of rectangle = 2 (w + l)

w = width

l = length

If you are still confused, please refer to the attachment below for a graphical explanation.

Solve:

w = w

l = 3w - 2

P = 36 inches

Given formula

P = 2 (w + l)

Substitute the value into the formula

36 = 2 (w + 3w - 2)

Simplify values in the parentheses

36 = 2 (4w -2)

Divide 2 on both sides

36 / 2 = 2 (4w - 2) / 2

18 = 4w - 2

Add 2 on both sides

18 + 2 = 4w - 2 + 2

20 = 4w

Divide 4 on both sides

20 / 4 = 4w / 4

w = 5

Hope this helps!! :)
