Answer:
Let the truck is driven X miles per day
Charges of company A will be = 90+0.4X
Charges of company B will be =30+0.7X
Let us find out value of X when charges of both companies are same
which means that 90+0.4 X= 30+0.7X
90-30 = 0.7X-0.4X
60 = 0.3X
60/0.3 = X
X= 200
The charges of both companies will be same if truck is driven 200 miles per day
Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)

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.
