28 men are needed to paint the room in 3 hours
<h3><u>Solution:</u></h3>Given that it takes 12 hours for 7 men to paint a room
We are asked to find number of men required to paint the room in 3 hours
Recognize, "paint the room" is 1 task. One job.
7 men -------- 12 hours ------ 1 job
(7/7) = 1 men ------- 12 x 7 (84) ------- same 1 job
The one men is rate is 84 hours to do the job
We can express this as 1/84 jobs per hour, the one-person rate
Now lets find how many men needed to paint the room in 3 hours
Let the required number of men for 3 hours be "a"
The rates of each person is simply additive.
corresponds to rate x hours = jobs and "a" is a variable for how many men
Thus 28 men are needed to paint the room in 3 hours
Answer:
3645 rabbits after 6 months.
Step-by-step explanation:
The population of a rabbit colony triples each month.
This means that the population of the colony after t months is given by:
In which P(0) is the initial population.
The population started with 5 rabbits.
This means that
So
How many rabbits are there after 6 months?
This is P(6). So
3645 rabbits after 6 months.
Good question!
First of all, you need to be aware of the following trigonometrical ratios\functions:
For angle A:
adjacent=12
opposite=35
hypotenuse=37
Hence:
