Answer:
- 40
Step-by-step explanation:
The absolute value always returns a positive value , that is
- | - 40 | = - | 40 | = - 40
The river will not reach a level of 7 ft. after 5 hours.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the water level after x hours.
Since the river is 1 ft below its average water level and begins to rise by a constant rate of 1.5 ft per hour. Hence:
b = -1, m = 1.5. The equation becomes:
y = 1.5x - 1
To reach a level of 7 ft. That is y = 7:
7 = 1.5x - 1
1.5x = 8
x = 5.3 hours
The river will not reach a level of 7 ft. after 5 hours.

<span>We will consider that the average volume of a cup is 200 ml, that is 0,2 liters.
That means 1 liter of liquid in cups is:
1 liter * 0.2 cup/liter = 5 cups
Then the equivalent of recommended liquid in number of cups is:
2.2 litres * 5 cup / liter = 11 cups of 200 ml each.</span>
that question does not make any sense
