Answer:

9.2yrs

Step-by-step explanation:

Given data:

 Ages of trees in the school property:

         3 years, 8 years, 10 years, 14 years, 11 years

The problem here is finding the mean age of these trees.

The mean is the average of a given data set. It is the sum of all the data given divided by the number of the data.

 Mean  = \frac{Total number of data}{number of data given}  = \frac{3 + 8 + 10 + 14 + 11}{5}    =  9.2yrs

20 men decided to complete a work in 30 days. but after 6 days 8 men left now in how many day the work will be completed​
Serga [27]

First, we convert it into a unit like this

20 workers × 30 days = 600 units work

After leaving the 5 workers, we have 35 days to complete the work.

In 35 days only 15 workers will do the work.

So the work completed in 35 days by 15 workers = 35 ×15 =525 units

Remaining unit = 600 -525 =75 units

This unit would do by 5 workers in (75/5) = 15 days.

So after 15 days, 5 workers should leave the job.

Ms.Rosenbaum buys 5 crates of apples at the market .Each crate cost $12.50 .She also buys one crate of pears for $18.75 .What is
Inga [223]
Ok so she wants but 5 crates of apples. And each crate cost 12.50 so you would multi 12.50 times 5, which is 62.05. She so wants to buy one crate of pears. One crate of pairs is 18.75. Since she is only buying one you don't need to multiply it but anything. But now you have to figure out the cost of the apples and pears together. So just add 62.05 and 18.75 together which is 80.80
