If a paper is 4/1000 inches think, how many of them will it take to equal 1000?
Well... if we take 1000 divided by 4 we get 250.
So 250 sheets of paper would be 1 inch thick...
Answer:
F(n) = 8.5*n yards, where n is the number of windows
Step-by-step explanation:
Suppose the house of Stephen's aunt has n windows.
Since he needs 8.5 yards of fabric for each window, then he needs 8.5 times n yards of fabric for the n windows.
Call F(n) the yards of fabric he needs for the n windows, then
F(n) = 8.5*n
For example, if auntie's house had 4 windows, then
F(4) = 8.5*4 = 34 yards.
If auntie's house had 6 windows
F(6) = 51 yards.
20
Step-by-step explanation:
Step 1:
Let the number be 50 and to find 40% of 50 is given interms of expression as follows
To express the percentage the following strategy is used
Eg: 40% = 
∴ To express 40% of 50 is

Step 2:
On simplification the above expression we could get

= 20
Because we know the leg with the measure is not the hypotenuse, the two legs would be 5 inches each. Using the Pythagorean Theorem, 5^2 + 5^2 = C^2, when C is the length of the hypotenuse. 5^2 is 25, so 25 + 25 = 50. We need to find the square root of 50, and the closest number is 7.07 or 7.1.
