Answer:
v = 3.64 ft/s
Step-by-step explanation:
Given that,
Radius of a carousel, r = 18 feet
It takes 31 seconds to complete revolution.
We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.
d = 2πr
d = 2π × 18 = 113.09 feet
Let v is the linear speed. It can be given by :
So, the linear speed of the carousel is 3.64 ft/s.
6582 dollars, divided equally amoung 32 employees.
Let's use multiplication to guess and get a close answer, it's a little easier than division:
32 x 100 = 3200 (but we need about twice this amount)
32 x 200 = 6400 (we still have 182 more dollars left over)
So now we know that each employee gets about 200 dollars, but let's get more specific.
Let's try 32 x 5, which equals 160. We can't "fit" any more in, because all that's left is 22 dollars.
We have 32 x 200 and 32 x 5, which together is 32 x 205 (= 6560) and the closest we can get to $6582 if we're splitting all of the money evenly.
Each employee should recieve $205.
Answer:
b=A/h
Step-by-step explanation:
In order to solve for b, we need to isolate b. We can do this by dividing both sides by h:
A = bh
A/h=b
b=A/h

Answer:
- 170 km on the ground
- 15 km over water
Step-by-step explanation:
Let t represent the amount of time spent over level ground. Then 5.75-t is the time spent over water. The total distance covered is ...
distance = speed · time
40(t) + 10(5.75 -t) = 185
30t + 57.5 = 185
30t = 127.5
t = 4.25
40t = 170
185 -170 = 15
The hovercraft covered 170 km on the ground and 15 km on the water.
