Here is your answer
Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.
Given the Scale of the Drawing as 3 : 1000
It means in the Drawing a Length of 3cm is Equal to 1000cm of the Actual Pool
It means in the Drawing a Length of 3cm is Equal to 10m of the Actual Pool
Given the Length of the Pool in the Drawing is 15cm
⇒ Actual Length of the Pool is 5 × 10m = 50m
Given the Width of the Pool in the Drawing is 7.5cm
⇒ Actual Width of the Pool is 2.5 × 10m = 25m
We know that Area of Rectangular Pool is Length × Width
⇒ Area of the Rectangular Pool = 50 × 25 = 1250m²
Answer:
C
Step-by-step explanation:
We want to find the inverse of g(x). One way to do this is to switch the g(x) and x in the original equation and then solve for g(x); that will give you the inverse.
Here, 
. Switch the g(x) and x to become: 
. Now solve for g(x) by isolating it:
Thus, the answer is C.
