Honestly the question doesn’t make sense. Imagine x=7 your saying john is 7 years old now. 5 years ago he was how old he is now (aka 7 for example) how old is he now? He can’t be how old he is now 5 years ago.

Jason's making punch by mixing 1/2 cup of orange juice and 1/5 cup of mango juice. He wants to mix the orange juice and mango ju

Korolek [52]

Answer:

Orange juice cups = 15

Mango juice cups = 6

Step-by-step explanation:

$\text{Fraction of orange cup used in one punch = }\frac{1}{2}\\\\\text{Fraction of mango cup used in one punch = }\frac{1}{5}\\\\\text{Now, to calculate the ratio : lcm of (2,5) = 10}\\\\So, Orange : Mango = \frac{1}{2}\times 10 :\frac{1}{5}\times 10=5:2\\\\\text{Now, required no. of orange juice cups = }\frac{\text{Orange cup ratio}}{\text{Sum of ratios}}\times 21\\\\=\frac{5}{7}\times 21=15\thinspace cups$

$\text{Now, required no. of mango juice cups = }\frac{\text{Mango cup ratio}}{\text{Sum of ratios}}\times 21\\\\=\frac{2}{7}\times 21=6\thinspace cups$

Hence, No. of Orange juice cups needed to make 21 cups = 15 and no. of Mango juice cups needed to make 21 cups = 6

291.87 irrational or rational

aliina [53]

291.87 is rational since the last (decimal) numbers aren't repeating.
If it was repeating (291.877777...) it would be irrational.
