Answer:
8.54 units (3s.f.)
Step-by-step explanation:
Distance between 2 points
Identify the coordinates of the 2 endpoints of the line:
(-5, 5) and (-2, -3)
Using the distance formula above,
length of line segment
![= \sqrt{[5 - ( - 3)]^{2} + [ - 5 - ( - 2)]^{2} } \\ = \sqrt{ {(5 + 3)}^{2} + ( -5 + 2)^{2} } \\ = \sqrt{ {8}^{2} + {( - 3)}^{2} } \\ = \sqrt{73} \\ = 8.54 \: units \: (3 \: s.f.)](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%5B5%20-%20%28%20-%203%29%5D%5E%7B2%7D%20%20%2B%20%5B%20-%205%20-%20%28%20-%202%29%5D%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%7B%285%20%2B%203%29%7D%5E%7B2%7D%20%20%2B%20%28%20-5%20%2B%202%29%5E%7B2%7D%20%7D%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B%20%7B8%7D%5E%7B2%7D%20%2B%20%20%7B%28%20-%203%29%7D%5E%7B2%7D%20%20%7D%20%5C%5C%20%20%3D%20%20%5Csqrt%7B73%7D%20%20%5C%5C%20%20%3D%208.54%20%5C%3A%20units%20%5C%3A%20%283%20%5C%3A%20s.f.%29)
I am not positive but it looks like it is 16 feet because you subtract from the length of the ladder which gives you 18-2 which equals 16
Answer:
88 degrees
Step-by-step explanation:
First add up all of your degrees
85+ 87+ 83+ 88+ 91+ 87+ 95= 616
Then divide that amount by the amount of different degrees you had in the question. You have 7 different degrees, so you will divide by 7.
616/7= 88
And boom you have your answer
40 mph
First you have 1200/30. You are trying to get to 1 hour, so in order to get 30 to one, you must divide 30 by 30 and 1200 by thirty as well. You get 40 miles per hour.
