180*60%=180*60/100=10800/100=108
180+108=288
So the total population os school is 288 students!

Answer:
The measurement of angle a is 42.5°
The measurement of angle b is 19.5°
Step-by-step explanation:
Angle a = a
Angle b = b
m < a + m < b = 62°
"m <" means "measurement of angle..."
m < a + m < b = 4m < a - 108°
Subtract m < a from both sides of the equation
m < b = 4m < a - 108° - m < a
Simplify
m < b = 3m < a - 108°
Substitute into original equation
3m < a - 108° + m < a = 62°
Add m < a + 3m < a
4m < a - 108° = 62°
Add 108° to both sides of the equation
4m < a = 170°
Divide both sides of the equation by 4
m < a = 42.5°
m < b = 62° - 42.5° = 19.5°

Answer:
6000 CENTIMETER'S
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
It is given that,
Number of $1 bills = 5
Number of $5 bills = 4
Number of $10 bills = 6
Number of $20 bills = 3
So,
Total number of bills = 5 + 4 + 6 + 3 = 18
We need to find the probability of a 1 then a ten (without replacement).
Probability of selecting $1 bill in first draw 
After one draw, the number of remaining bills is 18 - 1 = 17.
Probability of selecting $10 bill in second draw 
The probability of a 1 then a ten is
Therefore, the correct option is B.
