Answer: 
Step-by-step explanation:
For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:

In this case , according to the data given in the exercise, you know that:

Therefore, susbtituting those values into the formula, you get that length of AB is the following:

Answer: 3
Explanation:
She has 18 and uses half, 18/2=9
So now she has 9 eggs left, she uses one third, 9/3=3 (3 eggs is one third)
Now she only has six eggs left, she used half of those six to make dinner 6/2=3
She now has 3 eggs remaining.
There are two ways to find the total with tax
Either you can do
cost + cost x tax rate
or
cost x (1+tax rate)
Since the second one requires less steps, it's easier to do that.

The cost with tax is
$17.27
Answer:
option (A)
central angle = 0.375 rad
Step-by-step explanation:
Given in the question,
radius of the circle = 8 inches
arc of the circle = 3 inches
To find,
measure of a central angle
Central angles are subtended by an arc between those two points.
Formula to use:
<h3> s = (r) (θ)</h3>
<em>where r = radius </em>
<em> s = arc length </em>
<em> θ = angle in radians</em>
<em />
Plug in the values in the equation
<h3>3 = (8) (θ)</h3><h3>θ = 3/8 </h3><h3>0.375 rad</h3>
