Answer:
Markup amount = sellingprice - costprice
=12.50 - 5 = 7.5 is markup
I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!
For the trapezoid, the equation used to solve for the area is,
A = (0.5)(b₁ + b₂)(h)
where b₁ and b₂ are the measure of the bases and h is the height. Substituting the known values above,
1224 = (0.5)(70.5 + 65.5)(h)
h = 18
Thus, the height of the counter top is 18 inches.
Answer:
Step-by-step explanation:
They gave you an easy triangle. You can tell by the coordinates that X and Z are horizontally aligned, and Y and Z are vertically aligned, so Z is a right angle.
Area = 0.5(XZ)(YZ) = 0.5(3)(3) = 4.5 square units.
The given equation is,
It can be rewritten in the form of y=mx+c, where c is the y intercept.
Hence,
Put different values for x and find value of y.
When x=0, y=1.
When x=1,
The graph is,
