Answer:
897 liters
Step-by-step explanation:
The motor oil is composed of 8 liters of natural oil and 5 liters of synthetic oil. This means there is a ratio of 8/5. We have 552 liters of natural oil to y liters of synthetic. This is the ratio 552/y. Create a proportion that compares the two ratios.
Solve by cross multiplying.
8y = 5(552)
8y = 2,760
y= 345
345 liters of synthetic oil.
Together 552+345= 897 liters of motor oil.
Answer:
a.
b.
Step-by-step explanation:
Given
The data in the table
Solving (a): The coordinate that represents the unit rate
The unit rate is when its 1 pound
This is so because the unit rate is dollars per pounds.
<em>Hence, the coordinate is </em><em></em>
Solving (b): Equation of the graph
First, we calculate the slope (m)
Where:
The equation is then calculated as thus:
This gives:
Make y the subject
<em>Hence, the equation of the graph is: </em><em></em>
