Answer:
0%
Step-by-step explanation:
The chemist was tasked with removing 50mL from a stock solution of HCl acid.
Now:
- 1 Litre =1000 mL
- Volume to be removed=50mL=(50/1000)=0.05L
After the task, it was discovered that 2.45L of the stock solution remained.
- Volume removed=2.5L-2.45L=0.05L
Since the volume of acid removed by the chemist is equal to the volume of what the stock solution was reduced by, his percentage error is 0%.
We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.
Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.
y = 3x + 15
Answer: y = 3x + 15
Lets see how much each person pays per hour.
Danny: 75 / 5 = $15 per hour.
Martin: 51 / 3 = $17 per hour.
Danny offers a better deal.
Best of Luck!
