Answer:</h2>
The area of the top surface of the washer is: 160.14 square mm.
<h2>
Step-by-step explanation:</h2>
The top of the surface is in the shape of a annulus with a outer radius of 10 mm and a inner radius of 7 mm ( since the diameter of the hole is: 14 mm and we know that the radius is half of the diameter)
Now, we know that the area of the annulus region is given by:
where R is the outer radius and r is the inner radius.
Here we have:
Hence, we have:
Answer:
Pretty sure that it is False
Step-by-step explanation:
Sampling variation, random samples dont really reflect the population from where i is drawn, but it is close.
Answer:
I think the answer is A.
Step-by-step explanation:
Original shape: 7 x 5 x 225 x 6 x 12 x 45 = 25,515,000
A: 9 x 5 x 225 x 6 x 35 x 12 = 25,515,000
B: 14 x 10 x 255 x 12 x 24 x 45 = 462,672,000
C: 9 x 7 x 225 x 8 x 15 x 45 = 76,545,000
D: 8 x 4 x 225 x 6 x 12 x 35 = 18,144,000
This is probably not the way you would solve it but this is how I did it. Basically I multiplied all the numbers in each shape together.

Answer:
6 yards by 11 yards
Step-by-step explanation:
Factors of 66 are ...
66 = 1·66 = 2·33 = 3·22 = 6·11
The last pair of factors differ by 5, so represent the solution to the problem.
The width of the parking lot is 6 yards; the length is 11 yards.
For this case what you should see is each of the edges of the prism that are parallel.
We then have as parallel edges:
AC and GE
CG and AE
CD and GH
AB and EF
BD and HF
DH and BF
CD and EF
GH and AB
Answer:
8 pairs of parallel lines
