You are making iced tea for a friend who prefers it at 80% strength. The function y=(6)(1.0)+x(0.5)6+x gives the concentration of the tea after adding x fluid ounces of a 50% tea solution to 6 fluid ounces of 100% strength tea. How many fluid ounces of 50% strength tea should you add to 6 fl oz of 100% strength tea?

You should add 4 fluid ounces of 50% strength tea

Step-by-step explanation:

The actual fuction that gives the final concentration should be:

y=[(6)(1.0)+x(0.5)]/(6+x)

Probably it was a typing problem (a missing slash to indicate division). With the function given, the problem has no solution.

We want the strength of the iced tea to be at 80%.

So, to find how many fluid ounces of 50% strength tea (valor of x) you should add, we just need to use the equation of the final concentration with the value of y = 0.8 (y is the concentration of the tea after adding x fluid ounces of 50% strength tea):

0.8 = (6*1 + x*0.5) / (6+x)

0.8 * (6+x) = 6 + 0.5x

4.8 + 0.8x = 6 + 0.5x

0.3x = 1.2

x = 4 fluid ounces

b. the decimal could be two-tenths.

step-by-step explanation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
