Answer:
Cathy was driving at a speed of 67 miles per hour.
Step-by-step explanation:
Fined $15 for each mile per hour over the speed limit. Cathy was given a ticket for $105.
We solve this using a rule of three.
1 mile - $15
x miles - $105
Applying cross multiplication:
15x = 105
x = 105/5 = 7.
Cathy was 7 miles above the speed limit.
How fast was Cathy driving?
7 miles above the speed limit of 60 miles per hour, so 60 + 7 = 67 miles per hour.
Cathy was driving at a speed of 67 miles per hour.
Step-by-step explanation:
<em>it's </em><em> </em><em>absolutely </em><em>correct </em><em>.</em><em>.</em>
F= -1 2/3 or 5/3
In order to find the answer all you have to do is multiply both sides by -4/3.
-3/4f × -4/3 = f
-4/3 × 5/4 = -20/12
-20/12 simplified is -5/3 or -1 2/3

Answer:
Step-by-step explanation:
- The height (or altitude) is the perpendicular distance between the bases.
- In the case that the two bases have different lengths (a ≠ b), the height of a trapezoid h can be determined by the length of its four sides using the formula
where c and d are the lengths of the legs.
