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
The ratio is always 1:1:√2
the first one is true and the second one is false
Answer:
∠2 = 51°
Step-by-step explanation:
The sum of supplementary angles = 180°
Equate the sum of the angles to 180 and solve for a
11a + 19 + 6a - 9 = 180
17a + 10 = 180 ( subtract 10 from both sides )
17a = 170 ( divide both sides by 17 )
a = 10
Hence
∠2 = (6 × 10) - 9 = 60 - 9 = 51°
You are converting the numbers to a word problem.
1. 5+x = the number five plus x
2. 5-x= the number 5 minus x
3. 5x= five times x
4. 5/x= five divided by x
5. three-fourths of x plus 2
6. two minus three-fourths of x
7. 3 times x plus 10
8. ten times x plus three
