1. Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gal
Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.

Step-by-step explanation:

Consider the provided information.

Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.

This can be written as: \frac{20}{100}(x+y)

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: \frac{40}{100}x+\frac{10}{100}y

Now both the equation are equal.

\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y

0.2(x+y)=0.4x+0.1y

Hence, the required equations which represents the relationship between x and y is 0.2(x+y)=0.4x+0.1y.

Trevor has 3 2/5 pieces of cake left over. If she wants to split it between her and her 9 friends, how much will each
bagirrra123 [75]

Answer:

17/50.

Step-by-step explanation:

If we convert 3 2/5 into an improper fraction, we get 17/5.

If you don't read the question carefully, it's easy to think that the answer would be 17/5 ÷ 9. However, this is wrong.

The question says "her AND her 9 friends," so there are 9+1=10 people total.

Thus, the answer would be

17/5 ÷ 10 = 17/5 * 1/10 = 17/50.
