Answer: The system of linear equations are

L + W = 45

L = 4W - 5

Step-by-step explanation:

Let L represent the length of the deck.

Let W represent the width of the deck.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2( length + width)

The perimeter of a rectangular wooden deck is 90 feet. This would be expressed as

90 = 2(L + W)

Dividing through by 2

L + W = 45

The deck's length,L is 5 less than 4 times its width, W. This is expressed as

L = 4W - 5

Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.
vfiekz [6]

The measure of the Central Angle indicated is; 45°

<h3>How to find the central angle of a circle?</h3>

The central angle will be the angle subtended at the center by arc FE and arc CB.

Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;

Central Angle = 180° - 135° = 45°

Angle subtended by Arc CD at the center is;

θ = 180 - (81 + 45)

θ = 54°

An automatic doughnut machine can produce 1500 doughnuts in 9 hours.
Svetllana [295]

Answer:

1 hr, 48 minutes

Step-by-step explanation:

you can create a proportion:

doughnuts/hours = doughnut/hours (h)

1500/9 = 300/h

cross-multiply to get:

1500h = 2700

h = 27/15

h = 1 12/15, which is 1 hr, 48 minutes because 12/15 = 48/60
