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. (4 points)

im guesing 0 represents the like before you raise the height

the height of the slide is 10 feet higher then 0 because its off of the ground 10 feet

Step-by-step explanation:

Kayla should mark the level 3 whole tick marks to the left of the zero on the number line.  

This would mean the number is negative, for it is on the left of the zero. Another way to say this could be that the absolute value of -3 is three, for it is three whole tick marks from the zero.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
