10 men can build a house in 6 months. How long would it take 3 men?
find the value of 8(2e-7f)
16e-56f - correct
If there are 10 numbers in a list where is the number that (a)halfway:
(b)a quarter of the way:
(c)three quarters of the way:
Multiply 8 times 2e and 8 times - 7f.
The houses of parliament are 97.5 metres tall. They are drawn using a scale of 1cm=5m. How tall is the picture?
What is your answer?
16e-56f
18 3x6 month equal 18
To figure out how long it would take 3 men to build a house, we can use the concept of "man-months." A man-month is the amount of work one person can do in one month.
We are given that 10 men can build a house in 6 months, which means they can complete 10 * 6 = 60 man-months of work.
Now, let's find out how many man-months of work are required for 3 men to build the same house. Since the work required remains the same, the ratio of man-months to men should be constant.
So, the number of man-months required for 3 men can be calculated as (number of men) * (number of months).
Therefore, (3 men) * (X months) = (10 men) * (6 months)
We can solve for X by multiplying both sides by 3:
3 * X = 10 * 6
3X = 60
Dividing both sides by 3:
X = 20
Hence, it would take 3 men 20 months to build the house.
1 house/60 man months
1 house = (1 house/ 60 man months )* 3 men * x months
60 = 3 x
x = 20 months
