1.5 mm is what I would think the thickness of the penny would be
Answer:
Equations:
3c + 4m = 12.50
3c + 2m = 8.50
-----------------------
Subtract and solve for "m"::
2m = $4

Ans: m = $2.00
Step-by-step explanation:
Answer:
Correct option: D
Step-by-step explanation:
In the figure we have a right triangle, that is, one of the angles is a 90° angle. Therefore, we can use the Pythagoras' theorem to find the relation between the sides of the triangle:
Where b and c are cathetus of the triangle (sides adjacent to the 90° angle) and a is the hypotenuse (opposite side to the 90° angle).
So in our case, we have that x is the hypotenuse, and 40 and 42 are cathetus, so we have:
So the correct option is D.
