the ratio 6/5 means for every 6 boys there are 5 girls.
Add the ratio: 6+5 = 11
Divide class total by 11: 22/11 = 2
Multiply each ratio number by 2 to find the number of boys and the number of girls:
6 x 2 = 12 boys
5 x 2 = 10 girls.
10 out of the 22 kids are girls.
The probability of picking a girl would be 10/22, which reduces to 5/11
Answer:

Step-by-step explanation:
I look it up
Use the equation I/PT = R I is the interest P is the money before investment and T is the time
3a- 10° 3b- 55°
4a- 135° 4b- 45°
Complementary angles add up to 90°
Supplementary angles add up to 180°
Answer:
x = 13/3
Step-by-step explanation:
4(8x-3) - 30x = 5(x-5)
Distribute
32x - 12 - 30x = 5x -25
Combine like terms
2x -12 = 5x-25
Subtract 2x from each side
2x-12-2x = 5x-2x -25
-12 = 3x-25
Add 25 to each side
-12+25 = 3x-25+25
13 = 3x
Divide each side by 3
13/3 = x
