There are a couple of ways to do this. The easiest is to take the number of degrees between 42 and - 54 and divide by 12.
Method
the number of degrees is abs(42) + abs(-54) = 42 + 54 = 96
Now divide by 12
Hours = 96 / 12 = 8 hours.
I can't see the picture but, I think you can just look it up on google chrome.
Answer:
0, 8, 16, 24, 32
Step-by-step explanation:
plug in the values given for x into the 8x+8 equation
Example:
8(-1)+8
8(0)+8
The number is fairly easy to come across. The first thing that I see is that there are 45 students at the camp. This means, based on the clues given to me, that the number of 6th graders is odd. Because the number of 6th graders is half the number of 7th graders, and 8th grade equals 7th grade, that you have to use an even number less than 20, but more than ten.This leaves the numbers 14 and 18. Now we use trial and error. Half of 14 is 7. 14+14=28
28+7=35
35≠45
Half of 18 is 9.
18+18=36
36+9=45
45=45
So the answer is as follows:
6th grade: 9
7th grade: 18
8th grade: 18
Answer:
the correct answer would be 30
Step-by-step explanation:
because the side of an angle is the side it's pointing at which is BD. BD = a = 30
