Answer:
The complete answer is explained below.
Step-by-step explanation:
The problem is demanding to simply determine the number of years each color light would last.
We know the following information from the question:
- As it is clear that a red light remains TURNED ON 50% of the time.
- Green remains TURNED ON 42% of the time
- Yellow remains TURNED ON 8% of the time.
Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.
lets make conversions
As
Dividing 
hours by 
hours would bring 
days
Dividing days by 
days would bring 
years, meaning 11 years and 4 months.

Answer:
19400000/119000000 = 6.84 gallons
19000000/115000000 = 6.94 gallons
Answer:
Reference angle: 
is not defined.
Step-by-step explanation:
The angle 
goes from the positive x-axis to the negative y-axis.
Therefore the reference angle can be calculated as following:
We know that 
is:
If 
then 
, therefore 
is not defined, because the division by 0 is not defined.
A- 98+89+123=310 (boys)
A-102+105+117=324 (girls)
B-324-310=14 I found my answer by subtracting the girls from the boys and I got 14
C-They will need to hire 24 more teachers because if you add the students together you will get 644 then you divide it by 20 and you get 32 but since they already have 8 teachers you would just subtract 8 from 32 wich you get 24
45.3+3.21=48.51 which is greater than,its important to add the decimals because u would never know with what number your working with on decimal occasions.
