Answer:
43200 yd³
Step-by-step explanation:
The water reservoir is a rectangular solid that is a three dimensional shape with six quadrilateral faces (cuboid).
This reservoir has a base of 60 yards by 30 yards, and a vertical height of 30 yards. Therefore:
Volume of the reservoir = area of base * vertical height = 60 * 30 * 30 = 54000 yd³
This reservoir hence have a volume of 54000 yd³ when filled up with water.
After 3 months, the height of the water was down to 6 yards therefore the the volume is:
Volume after 3 months = area of base * vertical height = 60 * 30 * 6 = 10800 yd³
The amount of water used after 3 months = volume of water at beginning - volume of water after 3 months
The amount of water used after 3 months = 54000 - 10800 = 43200 yd³
The relationship between lines m & n is (a) the lines M and N have positive slope
<h3>How to describe the relationship?</h3>
The points are given as:
- Line M: (1, 4) and (2, 7)
- Line N: (1, 3) and (, 5)
From the above points, we can see that:
As x increases, the y values of both lines increase
This is an illustration of positive slope
Hence, the lines M and N have positive slope
