Answer:
- Q6. x = 17
- Q8. Yes, parallel
- Q9. No, not parallel
Step-by-step explanation:
Q6. Solve for x
<u>Use ratios of similar sides</u>
- 28/(82 - 28) = (2x + 8)/(5x - 4)
- 28/54 = (2x + 8)/(5x - 4)
- 14/27 = (2x + 8)/(5x - 4)
- 14(5x - 4) = 27(2x + 8)
- 70x - 56 = 54x + 216
- 70x - 54x = 56 + 216
- 16x = 272
- x = 272/16
- x = 17
Q8
If ratios are same, the lines are parallel
- 41.8/33 = (102 - 45)/45
- 41.8/33 = 57/45
- 41.8*45 = 33*57
- 1881 = 1881
Yes, lines are parallel
Q9
Incorrect, lines are not parallel
<u>Answer:</u>
The ratio of African Americans to Hispanics Americans present is 16 : 5
<u>Explanation:</u>
Given the people attending the soccer game were:
2800 among them are Caucasians
4800 are African Americans
1500 are Hispanics
And, 1400 of those were from other ethnic backgrounds
We have to find the Ratio of African Americans to Hispanics Americans
Therefore,
African Americans : Hispanics Americans = 4800 : 1500
Hence, the ratio of African Americans to Hispanics Americans present in the ratio were 16 : 5
Answer:
Neither
Step-by-step explanation:
To be parallel the lines have to have the same slope. In this case the slopes are not the same.
To be perpendicular, the lines have to have negative reciprocal slopes.
For example, if one slope is 6, then its negative reciprocal i (- 1/6). We do not have this also.
So, the lines are no parallel and no perpendicular.
