Which is equivalent to 80 Superscript one-fourth x?
Neporo4naja [7]

Answer:

The equivalent statement is (\sqrt[4]{80})^{x} ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- Any root can be a fraction power

- Ex: \sqrt{a}=a^{\frac{1}{2}}

   \sqrt[3]{a}=a^{\frac{1}{3}}

   \sqrt[4]{a}=a^{\frac{1}{4}}

   \sqrt[n]{a}=a^{\frac{1}{n}}

* The expression is (80)^{\frac{1}{4}x}

∵ (80)^{\frac{1}{4}x} can be written as (80^{\frac{1}{4}})^{x}

∵ (80)^{\frac{1}{4}}=\sqrt[4]{80}

∴ (80^{\frac{1}{4}})^{x} = (\sqrt[4]{80})^{x}

* The equivalent statement is (\sqrt[4]{80})^{x}

A shelter has enough food to feed an average of 80 hungry people a day for 14 days. If an average of 32 people are at the shelte
Katen [24]

Answer:

  • <u>35 days. </u>

Explanation

The capacity of the shelter is a constant. It is 80 people × 14 days.

That is an inverse relation: the product of the number of people and the number of days will be always the same.

As the number of people decreases the number of days that the food lasts increases, in a proportion such that the product of the days and the number of people is the same.

Thus, for 32 people the number of days the food lasts is x, such that:

  • 32 people × x = 80 people × 14 days

Solving for x:

  • x = 80 people × 14 days / 32 people
  • x = 35 days ← answer

The food will last 35 days.
