Answer:
1.25 cups
Step-by-step explanation:
The inicial concentration of the 10 cups of mixture is 10% of white vinegar and 90% water. We can then calculate the number of cups of white vinegar in the mixture:
Amount of white vinegar = 10% of 10 cups = 1 cup of white vinegar
Concentration of white vinegar = 1/10 (cups of white vinegar over cups of mixture
So, if we want to add white vinegar (x cups) until the mixture will be 20% white vinegar and 80% water, we have that:
Amount of white vinegar = (1+x) cups of white vinegar
Total number of cups in the mixture = 10+x
Concentration of white vinegar = 20% = (1+x)/(10+x)
(1+x)/(10+x) = 0.2
1 + x = 2 + 0.2x
0.8x = 1
x = 1.25 cups
You need to add 1.25 cups of white vinegar.
Answer:
The area of the dilated square is 196
R + 75 = 200 . You take away 75 from 200 and r = 125 so 125 is the answer
