Answer:
Answer B is correct
Step-by-step explanation:
In this problem, we use the method of ratio and proportion. This technique works by using the concept that there is a fixed ratio of compositions within a mixture. Speaking generally, there is a fixed ratio of the parts of the whole. So, all we have to do is equate both ratios.
5 L natural oil/ 6 L synthetic oil = x L natural oil/498 L synthetic oil
x = 415 L natural oil
So, if petrol oil contains 498 L synthetic oil, it has a corresponding amount of 415 natural oil. Adding these two would be the total volume of the petrol oil. That would be 415+498 = 913 L petrol oil.
Answer:
2 Units
Step-by-step explanation:
THere may be easier ways to do it, but I would just convert them to rectangular and find the distance between those.
(3, -60) becomes (3cos(-60), 3sin(-60)) = (3/2, -3*sqrt(3)/2)
(-5, 105) becomes (-5cos(105), -5sin(105)) = (5/2, -5sqrt(3)/2)
Now just use the distance formula, or in other words think of the two points as being connected by a horizontal and vertical line to form a right triangle. The idea is to find the hypotenuse of that right triangle.
sqrt((3/2 - 5/2)^2 + (-3sqrt(3)/2 + 5sqrt(3)/2)^2)
sqrt((-2/2)^2 + (2*sqrt(3)/2)^2)
sqrt(1 + 3)
sqrt(4)
