Ariver is rising at a rate of 3 inches per hour. if the river rises more than 2 feet, it will exceed flood stage. how long can the river rise at this rate without exceeding flood stage?

8 hours.

Step-by-step explanation:

Given:- A river is rising at a rate of 3 inches per hour.

⇒ In one hour, the increase in the level of river= 3 inches

If the river rises more than 2 feet, it will exceed flood stage.

⇒ the level of river must be less than 2 feet

We know that, 2 feet=2×12 inches [1 foot= 12 inches]

⇒ 2 feet = 24 inches

Thus time taken to rise at the same rate without exceeding flood stage

= i.e. Time taken to reach 24 inches=

= 8 hours.

The Option C shows the y-coordinate of the Point C: 7

The Point C is (-2,7)

Step-by-step explanation:

The area of a triangle can be calculated with this formula:

Where "b" is the base and "h" is the height.

We know that the segment AB, of 5 units long, is on the line , which is a horizontal line.

The point C is on the line , which is vertical.

Then we can say that:

Substituting the area and the lenght of the base into the formula and solving for "h", we get:

Then, the height (or the segment BC) of the triangle (Observe the figure attached) is 5 units long.

Therefore, the point C is: (-2,7)

And the y-coordinate of the point C is: 7
