lbvjy [14]

The normal price of each cookie is $1.15 derived from the equation, c =today price of each cookie + 0.75

<u>Solution:</u>

Given, Today each cookie costs 0.75 less than the normal price.

Right now if you buy 7 of them it will only cost you 2.80

We have to write an equation to determine the normal price of each cookie(c)

And, we are given that, today 7 cookies cost 2.80

Let the cost of one cookie today be “n”

Then we get,

Today 7 cookies ⇒ 2.8

Then, 1 cookie ⇒ n

By criss cross multiplication we get,

$\begin{array}{l}{7 \times n=2.8 \times 1} \\\\ {\rightarrow 7 n=2.8} \\\\ {\rightarrow n=0.4}\end{array}$

Which means that, each cookie costs $0.4 today

Now, we know that,

<em>normal price of each cookie, c = today price of each cookie + $ 0.75 </em>

c = 0.4 + 0.75

c= 1.15

Hence, the normal cost of each cookie is $1.15 derived from the equation, c = today price of each cookie + 0.75

$\sf\purple{The\:radius\:of\:the\:cylinder\:is\:approximately \:28 \:ft.}$

<h2><u>Given</u>:-</h2>

$\sf\blue{Height\:of\:the\:cylinder\:(h) }$ = 10 ft.

$\sf\pink{Volume\:of\:the\:cylinder}$ = 25,456 ft³.

$\sf\purple{The\:radius\:of\:the\:cylinder.}$

<h2><u>Step</u>-<u>by</u>-<u>step</u> <u>explanation</u>:-</h2>

We know that,

$\sf\red{Volume\:of\:a\:cylinder}$ = $\pi {r}^{2} h \\ ✒ \: 25456 \: {ft}^{3} = \pi {r}^{2} \times 10 \: ft \\ \: ✒ \: {r}^{2} = \frac{25456 \times 7 \: {ft}^{3} }{22 \times 10 \: ft} \\ ✒ \: {r}^{2} \: = \frac{178192 \: {ft}^{2} }{220} \\ \: ✒ \: {r}^{2} = 809.9636 \: {ft}^{2} \\ \: ✒\: r \: = \sqrt{809.9636 \: {ft}^{2} } \\ ✒ \: r \: = 28.45 \: ft$

Hence, the radius of the cylinder is 28.45 feet.
