Answer:
Using the concept of speed-distance-time, we find that the diameter of the circular path is 12 inches.
Step-by-step explanation:
Given that the object completes one revolution in 8 seconds. So, the circular speed of the object is 2πr/8 = πr/4 inches per seconds, where r is the radius of the circular path. The speed can be written as:
πr/4 inches per seconds = 60πr/4 inches per minute = 15πr inches per minute.
But, it is given that the circular speed of the object is 90π inches per minute. So,
90π = 15πr
r = 6 inches
Since, diameter is the double of radius, d = 2r = 12 inches.

Answer:
4 Units
Step-by-step explanation:
Just count the squares from X to Y or You can do just mental math
It's quite simple. Look:
Lets let S- be the age of Sally and B- can be the age of Beth
S+B=60
S-6=3(B-6)
S-6=3B-18
S=3B-18+6
S=3B-12
3B-12+B=60
4B=60+12
4B=72
B=72/4
B=18
B=60-18
B=42
The ages are (B)18 and (S)42
