Answer:
72 parts
Steps:
Convert the 4 hours into minutes. There are 60 minutes in an hour. Therefore, 4 hours = 240 minutes.
Divide 240 minutes by 40 minutes. This equals 6. Therefore, the machinist can produce the 12 parts 6 times in 4 hours.
Finally, multiply the 12 parts by the 6 times he can produce. Therefore, the machinist can produce 72 parts in 4 hours.
Actually Welcome to the Concept of the Angles.
Complementary angles are those which add up to get 90° , hence here
1.) 90-80 = 10° , 10 is complement of 80
2.) 90-(-120) = 210 , hence 210° is complement of -120
3.) 90-400 => 360°
4.) 90-95 = -5°
5.) 90-5 => 85°
6.) 90-(-35) = 125°
7.) 90-8 = 72°
all are the complement angles above.
Since Molly can make 4 pancakes in 6 minutes if you divide 60 by 6 you get 10 so Molly can make 10 pancakes every hour

Answer:
A scale copy of a figure is a figure that is geometrically similar to the original figure. This means that the scale copy and the original figure have the same shape but possibly different sizes. First you have to look at one of the sides of the scaled copy. If they are divisible by the numbers in the original shape, then try and see if the others sides of the scaled copy are scaled by the same factor. If they are, then they are a scaled copy.
