Answer:
11 years ago
Step-by-step explanation:
When Z is 3 times as old as M, the ratio of their ages is ...
M : Z = 1 : 3
The difference in their ages at that time is 3 - 1 = 2 "ratio units". The difference in their current ages is 50 -24 = 26 years, so 1 ratio unit = 26/2 = 13 years. Z was 3 times as old as M when M was 13 years old. (Z was 39.)
That was 24 -13 = 11 years ago.
_____
For most age problems, the difference between two ages is assumed to be a constant.
Answer:
15.7 cm
Step-by-step explanation:
The perimeter of the entire circumference is
entire perimeter = 2п r
п = 3.14 (aprox)
r = radius = 3cm
entire perimeter = 2*3.14*3 = 18.84 cm
the entire perimeter of the circumference corresponds to 360 degrees
then,
proportions:
18.84 cm ⇔ 360°
F cm ⇔ 300°
F = 18.84*300/360
F = 15.7 cm

Answer:
Step-by-step explanation:
The number of adults in the family that is going to the amusement park is 2.
The number of children in the family that is going to the amusement park is 4.
Admission is a 21 point 75 for adults and 15 point 25 for children. This means that the admission cost for each adult is 21.75 and the admission cost for each adult is 15.25. Therefore,
The total cost of admission for the 2 adults would be
21.75 × 2 = 43.5
The total cost of admission for the 4 children would be
15.25 × 4 = 61
Therefore, the total cost of the families admission would be
43.5 + 61 = 104.5
