333 erasers cost \$4.41$4.41dollar sign, 4, point, 41. Which equation would help determine the cost of 444 erasers? Choose 1 ans

Rudiy27

Answer:

Option D will be correct.

Step-by-step explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be $\frac{333}{4.41} = \frac{444}{x}$

⇒ $\frac{3}{4.41} = \frac{4}{x}$

Therefore, option D will be correct. (Answer)

If y=a sin 3x+ b cos 3x and <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7D%20y%20%7D%7Bdx%5E%7B2%7D%20%7D" id="TexFormu

Step-by-step explanation:

You have to do first and second derivatives :

y = a sin 3x + b cos 3x

dy/dx = 3a cos 3x - 3b sin 3x

d²y/dx² = - 9a sin 3x - 9b cos 3x

Next, you have to compare it :

let d²y/dx² = ky,

-9a sin 3x - 9b cos 3x = k(a sin 3x + b cos 3x)

-9(a sin 3x + b cos 3x) = k(a sin 3x + b cos 3x)

Therefore, k is equals to 9.

A newspaper’s cover page is 3/8 text, and photographs fill the rest. If 2/5 of the text is an article about endangered species,

jolli1 [7]

Answer:

$\frac{3}{20}$

Step-by-step explanation:

Let x be the cover page

We are given that a newspaper 's cover page is $\frac{3}{8}$ text and photograph fill the rest.

We have to find that how much part of cover's page is the article about endangered species

Text = $\frac{3}{8}x$

Remaining part = $x-\frac{3}{8} x$

Remaining part = $\frac{8x-3x}{8}=\frac{5}{8} x$

Therefore, a newspaper;s cover page fill with Photograph = $\frac{5}{8}$

If the article about endangered species= $\frac{2}{5}$ of text

Therefore, the article about endangered species= $\frac{2}{5}\times\frac{3x}{8}=\frac{3}{20}x$

Hence, the article about endangered species is $\frac{3}{20}$ of the cover page.
