What is the arc measure of \stackrel{\LARGE{\frown}}{AC}
algol [13]

Answer:

72°

Step-by-step explanation:

Given that the radius(r) of the circle is 10 units and the length of arc ABC is 16π

The length of arc ABC = \frac{\theta}{360}*2\pi r

Where θ is the central angle in degrees.

Since the length of arc ABC is 16π,

16\pi=\frac{\theta}{360}*2\pi r\\16\pi=\frac{\theta}{360}*2\pi *10\\\theta=\frac{16\pi *360}{2 \pi *10} \\\theta=288^0

The angle in a circle = 360°, therefore:

Central angle for arc AB (θ) = 360 - Central angle for arc ABC = 360 - 288 = 72°

Therefore the arc measure of arc AB is 72°

What is an irrational number between 5.2 and 5.5?
Mila [183]
5.2 \ \textless \  x \ \textless \  5.5 \\  \\ \sqrt{5.2^2} \ \textless \  \sqrt{x^2} \ \textless \  \sqrt{5.5^2} \\  \\ \sqrt{27.04} \ \textless \  \sqrt{x^2} \ \textless \  \sqrt{30.25}

Let x^2 be any whole number between 27.04 and 30.25.

x^2 = 29 \\  \\ x = \sqrt{29}

Write the slope intercept form of the equation of the line through the given point with the given slope through(-3,2), slope = -
Alex17521 [72]
So basycilly slope intercept form is y=mx+b where m=slope and b=y intercept
slope=-1
subsiute
y=-1x+b
y=-x+b
so we are given the point (-3,2)
x=-3 and y=2 is one solution
subsitue and solve for b
2=-(-3)+b
2=3+b
subtract 3 from both sides
-1=b

the slopt inercept form is y=-x-1

What is the unit rate for 108 diapers for 25.18 dollars
Alenkasestr [34]
<span><span>1.       </span>Question: Find the Unit rate for 108 diapers for 25.18 dollars.
Let’s analyze the given question. In a total of 108 diapers for 25.18 dollars.
Thus we need to find the amount of every 1 diaper then.
=> 108 diapers – is the total number of items
=> 25.18 dollars -  the total amount paid
=> Since we are looking for the price of each diapers, we need to divide the amount with the number of diapers.
=> 25.18 / 108 = 0.23 dollars.
Thus the unit rate is 0.23 dollars/ diaper</span>
