How deep is a well that takes eight cranks on the six- inch diameter windlass to raise the bucket?

In order to answer this, you would need to find the circumference of the windlass. This would represent the distance of one rotation. When you know the distance of one rotation, you would then multiply it by eight for all eight Kranks. This is knowing each crank is a complete turn. Here is the formula C= pi times the diameter. So, 3.14 x 7 is 18.84 inches for 1 crank. 18.84 inches times 8 equals 150.72 inches. This is an approximation because pi is an approximation.

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of _2?
Crank
The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28

A family is purchasing a house and needs to finance a 195,000 mortgage from the bank with an annual percentage rate (APR) of 5.3
maksim [4K]

Calculate the monthly payment:

195,000 x ( (0.05/12)x1+0.053)^12)/(1+0.053)^12-1)

Monthly payment = 1,082.84

Multiply monthly payment by 12 to get one year: 1082.84x 12 = 12994.08

Now multiply by 30 years:

12994.08 x 30 = 389822.40

The answer is $389,822

Subtract:<br> 7' 5" – 2' 8" =
yKpoI14uk [10]

Answer:

4'9"

Method 1:

First, convert both numbers into inches. Remember that 1' = 12", and the rest is like a remainder.

7'5" = (7*12)+5 = 84+5 = 89

2'8" = (2*12)+8 = 24+8 = 32

Next, subtract the two numbers.

89 - 32 = ?

89 - 32 = 57

There's your answer! You can change it back into feet by dividing it by 12.

57 / 12 = 4.75 = 4'9"

Method 2:

Another way of solving this problem is to borrow from the "feet" place.

7'5" - 2'8"

You can't take 8 away from 5, so you borrow from the "feet" place. Remember that unlike normal borrowing, you need to add 12 instead of adding 10.

6'17" - 2'8" = 4'9"

Whichever method you choose, you should get the same answer!
