Midpoint

We know AC is a segment and B is its midpoint. This means the length of the segment AB is half the length of the segment AC. This also means the length of the segment BC is half the length of AC, and equal to AB.

This can be visualized as follows:

Since AB=7, then BC = 7 and AC=AB+BC = 14

Answer: BC = 7, and AC=!4

According to the equation, which choice represents the fixed cost of
kodGreya [7K]

Answer:

A) 3500

Step-by-step explanation:

C(x) = 0.75x + 3500

C(x) = Total cost

0.75x = variable cost

3,500 = fixed cost

The fixed cost of the function = 3,500

Variable cost refers to cost of production that changes during production such as cost of raw material, wages of workers etc.

Fixed cost are cost of production that remains the same (does not change) with the production process such as building, machineries etc

Total cost is the addition of all cost of production, that is, the addition of fixed cost and variable cost

How can you use mental math to determine that 28,000 divided by 70 equals 400?
Ann [662]
Hello! First I would just look at the numbers without the zeros. So 28/7. This equals 4. Next cross out the same number of zeros on each side of the equation. In this instance, the 7 has one zero and the 28 has three so you can cross out one zero on each side. This leaves you with two zeros left over to add to the end of the 4. So you end up with 400. 

I hope this helps!
