Nate is curious to learn how much elephants eat compared to the largest animal on Earth, the blue whale.
He does some research and finds that a full-grown blue whale eats about 1,460,000 pounds of krill per year.
Write and solve a question about how much food blue whales eat. Use scientific notation in your answer.

The equation representing the number of whales (x) and the krills eaten (y) by them in a year is .

Given information:

A full-grown blue whale eats about 1,460,000 pounds of krill per year.

Let x be the number of blue whales and y be the number of krills eaten by x whales in a year.

So, the general relation between x and y can be written as,

Now, let there are 3 whales in a region. So, the number of krills eaten by them in a year will be,

So, 3 whales will eat 4380000 pounds of krills in a year.

Therefore, the equation representing the number of whales and the krills eaten by them is .

y = 1.46 * 10⁶ x

Step-by-step explanation:

We can write the following equation:

Let x to represent the number of blue whales and,

let y to represent the total krill eaten by x blue whales per year

1'460,000 = 1.46 * 10⁶

y = 1.46 * 10⁶ x

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
