Answer :
- Total number of people in the room = 18
- Number of people with red hair = 2
- Number of people not with red hair = 18 - 2 = 16
- Probability of picking a person who doesn't have red hair =
Probability = 16/18
Reduce the fraction with 2
Probability = 8/9
Answer: -15p + 41q
Step-by-step explanation:
Problem: -9(4p-6q) + 8q- 7(3q - 3p)
1. Expand by distributing terms
−(36p−54q) + 8q − 7(3q − 3p)
2. Expand by distributing terms
−(36p−54q) + 8q − (21q − 21p)
3. Remove parenthesis
−36p + 54q + 8q − 21q + 21p
4. Collect like terms
(−36p + 21p) + (54q + 8q − 21q)
5. Simplify
-15p + 41q
We have to find the area which multiplied by 160 gives 1 square mile.
We know that : 1 square mile = 0.3867 sq km.
So it is not from the metric system.
The acre is exactly 1/640 of a square mile. 1/4 of the square mile is 160 acres.
1 sq mile = 640 acres
1 sq mile = 160 * 4 acres
Answer: 4 acres.
