A. Simplify the fraction of the arcs degree over 360 then multiply by the circumference of the circle
Schach [20]4 years ago

Answer:

<h2>A. Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.</h2>

Step-by-step explanation:

The first choice describes the right way to find the length of an arc in a circle.

The length of an arc is defined as

L=2\pi r (\frac{\theta}{360\°} )

Where 2\pi r represents the circumference of the circle and \theta represents the arc's degree measure.

So, as you can observe through this formula, we need to divide the arc's degree measure by 360°, and then multiply this result with the circumference of the circle, that's the right way based on the definition of arc length.

Therefore, the right answer is A.

Line g is shown on the graph.
alisha [4.7K]

The linear equation that defines the line G can be written as:

y = -(1/3)*x + 5

<h3>How to get the equation of the line G?</h3>

A general linear equation written in the slope-intercept form is:

y = a*x + b

Where a and b are real numbers, a is the slope and b is the y-intercept.

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

In this case we know that the line passes through (-3, 6) and (0, 5), then the slope is:

a = (5 - 6)/(0 - (-3)) = -1/3

The linear equation is something like:

y = (-1/3)*x + b

We know that it passes through (0, 5), then:

5 = (-1/3)*0 + b

5 = b

We conclude that the linear equation can be written as:

y = -(1/3)*x + 5

Lee sells electronics. He earns a 5% commission on each sale he makes. If lee sells the PS5 for 500, how much does lee make in c
babymother [125]

Answer: Lee would make $25 on commission.

Step-by-step explanation: I found this by multiplying 500 by .05 or 5%. Lastly you can check this by taking 25 times 20, because 5% x 20 = 100%, so if 25 was really equal to 5% then it would equal the whole, or 500.

Hope this helps.

5 hockey pucks and three hockey sticks cost $23. 5 hockey pucks and 1 hockey stick cost $20. How much does 1 hockey puck cost?
Andrews [41]

Let P be the cost of pucks, S the cost of sticks.

1.5p+3s=23

2.5p+s=20

subtract eqn 2 from 1,we get

5p+3s-5p-s=23-20

2s=3

s=3/2=1.50

Then from eqn 2,

5p+3/2=20

5p=40/2-3/2

p=37/10=3.70

Therefore,pucks cost $3.70 and sticks cost $1.50
