Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
Answer:
607.32
Step-by-step explanation:
two semi circles make a whole circle so use the normal circumfrence formula 2 pi r
circumfrence = 433.32
the perimeter of the rectangle is 87 + 87, because they are on the outside of the field.
The answer is 607.32
We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.
Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.
1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>
We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.
250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left
The graph depicts a linear equation
The equation of the graph is:
From the graph, we have the following points:
So, the slope (m) is:
This gives
The equation is then calculated as:
This gives
Hence, the equation of the graph is:
