The weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles was 3:4

Let 3x and 4x are the seeds from the smaller and bigger pile.

= 4x + 2  (greedy hamster placed another 2 pounds of seeds in the bigger pile)

= 3x - 1/4 (ate 1/4 pound from the smaller pile)

4x + 2 = 5x

Because the quantities of seeds in those piles is in the ratio of 5:16

After solving:

x = 2

Smaller pile weight = 3x = 3(2) = 6

Bigger pile wieght = 4x = 4(2) = 8

Thus, the weight of each pie will be 6 and 8 pounds respectively if the ratio of the seeds in these piles 3:4

goblinko [34]

Answer:

Eggs: 25 cents ea.

Pounds of peanuts: $2.50 ea.

Rolls of toilet paper: 50 cents ea.

Apples: 35 cents ea.

Step-by-step explanation:

This is assuming you meant $3 for 12 eggs, and $2 for 4 rolls of toilet paper.

For the eggs, I did 3 / 12 = .25 (aka 25 cents);

For the peanuts: 7.50 / 3 = $2.50;

For the toilet paper: 2 / 4 = .50 (aka 50 cents);

For the apples: 3.50 / 10 = .35 (aka 35 cents).

Hope this helped ~

:D
