Jessica gets her favorite shade of purple by mixing 1/3 cup of blue with 1/2 of red. How many of blue and red paint does Jessica
Vitek1552 [10]

Answer:

8 cup of blue

12 cup of red

Step-by-step explanation:

The first thing is to calculate how much black paint is produced, assuming that the volumes add up, we have to:

1/2 + 1/3 = 5/6

5/6 cup of paint is produced, I want to know how much I need to produce 20 cups, I divide the value I want by the ideal value, that is, 5/6 and thus I obtain the factor that I require:

20 / (5/6) = 24

Now I multiply by 24 each quantity of blue and red paint

1/2 * 24 = 12

1/3 * 24 = 8

Which means you need 12 cups of red paint and 8 cups of blue paint

Help! This is so confusing please
Rus_ich [418]

Given equation is f(x)=6^x

Now it says to find f(2)

that simply means plug x=2 because we see that 2 is written in place of x in f(x) and f(2)

f(2)=6^2

f(2)=6*6

f(2)=36

Hence final answer is f(2)=36
