Answer:

9.42

Step-by-step explanation:

Hey There!

The first step of this problem is to find the formula for arc length

$arc-length=2\pi r(\frac{0}{360} )$

r=raduis

0 = angle

now we just plug in the values

$arc-length=2\pi 10\frac{54}{360} \\2\pi =6.283185307\\6.283185307x10=62.83185307\\62.83185307\frac{54}{360}=9.424777961$

so the arc length equals 9.424777961

the last step is to round to the nearest hundreth

so your final answer is 9.42

The value of Maggie’s car decreased by 20% since last year when she bought it if the car is not worth 21,000 how much was the ca

leonid [27]

Answer:

Step-by-step explanation:

You would do 21,000×0.20, which equals 4,200. Since 4,200 equals 20% of 21,000, then you would do 21,000-4,200, which equals 16,800. So the car is worth $16,800 dollars this year.

Answer:

$\huge\boxed{\sf No}$

Step-by-step explanation:

<u>The ordered pairs for the given relation are:</u>

=> {(6,2)(-1,2)(-1,-1)(4,3)}

Domain => x-inputs of the ordered pairs

Domain => (6,-1,4)

Range => y-inputs of the ordered pairs

Range = (2,-1,3)

Since, <em>the values in the domain (-1) are being repeated, this relation is not a function.</em>

What is the equation for two thirds of a full turn

wlad13 [49]

Full turn = 360 degrees
2/3 of a full turn.
So 1/3 of a turn is 120 degrees
Since it’s 2/3, you add another 120 to make 240

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200.

worty [1.4K]

On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.

<h3>What is the linear system?</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The linear equation is shown below.

$\rm \dfrac{1}{5}x - \dfrac{2}{3}y = 30$
