What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.
What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?
Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L
Now, add both synthetic oil and natural oil to find amount of petrolyn oil.
355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil
For this case we have the following function:
By power properties we can rewrite the function as follows:
We have then:
Then rewriting the function we have:
Answer:
an equivalent function to 
is:
4^3
You Would Write Is 4x4x4
You Would Verbally Say Four To The Third Or Four Cubed
Answer:
For the first one the diameter is 22. Circumference is 69.08. Area is 379.94
Second question is radius is 12. Circumference is 75.36. Area is 452.16
Step-by-step explanation:
Radius = d/2
Diameter = r*2
Circumference = 3.14*d
Area = r^2*3.14
Answer: 2^(3) equals to 8.
So the x value is 3.
Step-by-step explanation: Hope this Helps!
