Answer:
Step-by-step explanation:
Given : Casey was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line: −8, which represents the depth of water in the swimming pool +7, which represents the height of the slide at the pool
To Find : What does 0 represent in this situation?
Describe the height of the slide in relation to 0 in the situation
Casey held a pole in the swimming pool. The bottom of the pole was at a depth of 2 feet. How should Casey mark the level of the bottom of the pole on the number line
Solution
0 represent in this situation - Top surface of Swimming pool - Surface matching with ground
height of the slide in relation to 0 in the situation = 7 feet
pole was at a depth of 2 feet = - 2
For this case, we perform the conversions:
First roll:
We make a rule of three to determine the number of "c" boxes that can be packed with 300 meters of adhesive tape.
1 -----------> 4.2
c -----------> 300
You can pack 71 boxes.
Second roll:
We make a rule of three to determine the number of "c" boxes that can be packed with 70 meters of adhesive tape.
1 -----------> 4.2
c -----------> 70
You can pack 16 boxes.
Third roll:
1 -----------> 4.2
c -----------> 50
You can pack 11 boxes.
Thus, in total you can pack
Answer:
98 boxes
1,000 is independent because nothing it changing it.
150x is dependent because 150 relies on the variable x.
