1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
Answer:
53°, 127°, 127°
Step-by-step explanation:
<u>Two intersecting lines form two pairs of angles:</u>
- Pair of vertical angles. They are opposite to each other and are equal
- Pair of adjacent angles which are supplementary angles and their sum is 180°
<u>So if one of the angles is measured 53°, then the other angles are:</u>
- 53°- vertical angle with the first one
- 180° - 53° = 127°
- 180° - 53° = 127°
Maybe if you need to measure a piece of clothing
<span>It can be assumed that the sample mean would would be approximately normal by the mean distribution theorem. The mean distribution theorem states that a large enough sample size will have a distribution and mean approximately the same as the population mean. A sample of 250, half the size of 500, is of sufficient size to assume the distribution mean will be approximately normal like the population mean.</span>
Answer: H. 139.50
Step-by-step explanation:
Multiply 9 by 8 first and you get 72. Then multiply 9 by 7.5 and you get 67.5 then add 72 and 67.5 and you get 139.5 or 139.50
