1. If Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
2A. If Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
If Sheryl works 9 hours she will make approximately 117 currency.
Step-by-step explanation:
Step 1:
To calculate how much Sheryl makes if she works 6.5 hours a day, we check the graph to see what the y value of the graph is when .
When , the line falls on
So if Sheryl works 6.5 hours in a day, she makes approximately 85 currency.
Step 2:
The two points on the graph are at (0, 0) and (1, 13).
This means that if Sherly had not worked for a single hour, she would get no money.
If she worked for 1 hour, here wage would approximately be equal to 13 currency.
These two statements explain the two points on the graph.
Step 3:
To calculate how much Sheryl makes if she works 9 hours, we must create an equation that represents how much money she makes.
If she earns approximately 13 currency an hour, her wage is , where x is the number of hours worked and y is the wage.
When ,
So if Sheryl works 9 hours she will make approximately 117 currency.
Answer:
It takes the frog 7 hours to get out of the well.
Step-by-step explanation:
We know that the well is 11 feet deep and the frog can climb 3 feet per hour.
Each time it climbs, it rests for an hour, and decreases its height by 1 foot.
So, if the frog reaches 3 feet in the first hour, then in the next hour it is 2 feet.
Lets calculate with the same pattern:
1st hour: 3 feet
2nd hour: feet
3rd hour: feet
4th hour: feet
5th hour: feet
6th hour: feet
5th hour: feet
6th hour: feet
7th hour: feet
Therefore, it takes the frog 7 hours to get out of the well.
