Kayla was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line: −9, which represents the depth of water in the swimming pool
+10, which represents the height of the slide at the pool

Part A: What does 0 represent in this situation? (3 points)

Part B: Describe the height of the slide in relation to 0 in the situation. (3 points)

Part C: Kayla held a pole in the swimming pool. The bottom of the pole was at a depth of 3 feet. How should Kayla mark the level of the bottom of the pole on the number line? Explain how you determined this

Part A:

0 = the surface of the swimming pool

Part B:

Since the height of the slide is measured at +10 feet, then this means

that the top of the slide is 10 feet above the surface of the water (0) in the swimming pool.

Part C:

Since 3 feet of the pole was put in the water, then Kayla should mark the of the bottom of the pole as -3 feet.

A.

It represents the surface of the water.

B.

height of the slide is 10 feet and the,

surface of water is 0 ,

then the relation between the slide and surface of water is of 0:10.

C.

Kayla have to go under 3 feet ( 1/3 of the depth of the pool. And she can mark the bottom of the pole. that is,

1/3 of -9 = -3 feet below the zero, surface of the water.

no
