A village wishes to measure the quantity of water that is piped to a factory during a typical morning. A gauge on the water line

anzhelika [568]

Answer:

570 m³

Step-by-step explanation:

The volume of water is the product of flow rate of water and the time taken. We are to get the volume of water used between 6 am and 9 am, that is for 3 hours (9 - 6).

We are given the flow rate at 6 am and the flow rate at 9 am, but this flow rate changes between 6 am and 9 am. To get the estimate of the water used, Let us assume that it flows at the same flow rate as it was at 6 am throughout, hence:

$V_L= 100 m^3/h * 3h=300\ m^3$

Also, let us assume that it flows at the same flow rate as it was at 9 am throughout, hence:

$V_R= 280 m^3/h * 3h=840\ m^3$

To get the best estimate of the total volume, let us find the average of the two values, hence:

$Volume=\frac{V_L+V_R}{2} =\frac{300+840}{2}=570\ m^3$

A farmer sells 7.8 kilograms of pears and apples at the farmer's market. 3/4 of this weight is pears, and the rest is apples. Ho

tangare [24]

Answer:

He sold 1.95 kilograms of apples.

Step-by-step explanation:

First we find out what 3/4 of 7.8 is.

3/4 of 7.8 = 5.85

Next we subtract 7.8 by 5.85

7.8 - 5.85 = 1.95

So, the answer is 1.95

Hope this helps! :)

First, you need to find the area of the room.

299×34=10166

Once you found the area of the room, you need to find the cose of the tile.

10166×11=111826

It will cost $111,826 to cover 10166 square feet.
