Answer:
A
Step-by-step explanation:
This is a sector of a circle measuring 140° and the circle has radius 9 inches.
We can use the formula for the area sector of a circle to figure this out.
Area of a Sector of a Circle = 
Where
is the intercepted angle (here it is 140), and
r is the radius (here it is 9)
<em>plugging into the formula, we get:</em>
<em>
</em>
rounding to nearest tenth, it is 99.0 inches squared.
Option A is right.

Answer:
$12,172
Step-by-step explanation:
The year 2016 is 16 years after the year 2000. So, because x = the number of years since 2000, which we have determined is 16, you need to substitute it for x in the equation.
So,
y = 426(16) + 5,356
REMINDER: The parenthesis tell you to multiply, so:
y = 426 × 16 = 6,816
6,816 + 5,356 = 12,172
