Four friends shared 1/2 of one carton of orange juice and 1/4 of another carton of apple juice. What fraction of each carton of
Natalka [10]

Answer:

\dfrac{1}{16}

\dfrac{1}{32}

\dfrac{3}{32}

Step-by-step explanation:

So in the first carton of orange juice 4 friends shared the juice.

This can be shown as:

\dfrac{(\dfrac{1}{2})}{4}

\dfrac{(\dfrac{1}{2})}{4}=\dfrac{1}{16}

The 4 friends got 1/16 of the carton each in the first carton of OJ.

Next for the second carton, it can be shown as:

\dfrac{(\dfrac{1}{4})}{4}

\dfrac{(\dfrac{1}{2})}{4}=\dfrac{1}{32}

The 4 friends got 1/32 of the carton each in the first carton of OJ.

Now to see how much they got in total each, we simply add 1/16 to 1/32

Total OJ each = \dfrac{1}{16}+\dfrac{1}{32}

Total OJ each = \dfrac{3}{32}

Each friend got a total of \dfrac{3}{32} each from both cartons of OJ.

there are 1024 players in a tennis tournament in each round half of the players are eliminated which function can be used to fin
jonny [76]

Answer: f(x) = 1,024(0.50)^x

Step-by-step explanation:

Hi, to answer this question we have to apply a decreasing rate formula:

f(x)= P (1 - r) ^x

Where:  

p = original number of players

r = decreasing rate (decimal form, since half of the players are eliminated the percent decrease is 50%)

x = rounds  

f(x) = number of players after x rounds

Replacing with the values given:

f(x) = 1,024(1-50/100)^x

f(x) = 1,024(1-0.5)^x

f(x) = 1,024(0.5)^x
