Answer:
The answer to your question is 19.2 feet.
Step-by-step explanation:
With the data given, we can see that we have a right triangle in the middle of the bigger one. Also, we can see that we have four triangles inside the biggest one, and all these triangles have the same size.
Then we can know the length of the three sides of:
BC = DE + DE = 3.2 + 3.2 = 6.4
AB = EF + EF = 4 + 4 = 8
AC = DF + DF = 2.4 + 2.4 = 4.8
Perimeter = BC + AB + AC = 6.4 + 8 + 4.8 = 19.2 feet

OOOKKKKK.........
We all know that a well is circular. So, First, lets find out the circumference of the wheel.
Given :
radius = 10 feet
π = 22 / 7
We know,
Circumference = 2πr
= 2 × (22 / 7) × 10
= 62.9 ft.
Now,
One revolution means the wheel has covered a distance equal to its circumference. So, 22 revolutions per minute means that the wheel is covering 22 times its circumference in 1 minute. So, Lets convert the revolution to feet.
Given,
The wheel is travelling at 22 revolutions per minute.
= 22 * Circumference per minute
= 22 * 62.9 ft. per minute
= 1383.8 ft. per minute
Now, that we know how much feet it is travelling in 1 minute, we can easily find how much it takes it to travel 10 feet.
Using unitary method,
The wheel travels 1383.8 ft. in 1 minute
The wheel travels 1383.8 ft. in 60 seconds.
The wheel travels 1 ft. in (60 / 1383.8) seconds.
The wheel travels 10 ft. in (60 / 1383.8) * 10 seconds.
= 0.4 seconds
So, the answer is 0.4 seconds. Of course...the answer is rounded!!

Step-by-step explanation:
In order to change from 35 to 62, we have to add 27. So, the question becomes: which percentage of 35 is 27?
To answer this question, we set this simple equation
And solving for x we have
So, if you change from 35 to 62, you have an increase of about 77%
