55 if you mean one half
5500 if you mean 50 times 110
60 if you mean 50 from 110
Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.
<h3>What is a
circle? </h3>
A circle is the locus of a point, such that the distance from a fixed point (center) is always constant.
The circumference of a circle is given by:
Circumference = π * diameter

Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.
x+y=170 (We know that soda + dogs is 170)
x-50=y (We know that dogs is equal to 50 less than sodas)
We can use substitution to solve this system of equations.
x+y=170
Sub in the value of y from the second equation
x+(x-50)=170
2x-50=170
2x=220
x=110
We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.
x+y=170
110+y=170
y=60
So, there were 60 hotdogs sold and 110 sodas sold.
The horizontal line has equation 
. The line is solid, and everything below it is shaded, which translates to the inequality 
. (so not B nor D)
The dashed line must have equation 
. Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both 
and 
, so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be 
.
This means the answer is A.
