What is the perimiter, in feet, of a square whose area is 121 square feet

Ainat [17]

Square needs to have all equal sides and length and width are the same.

So sqrt the area.

sqrt 121 = 11

11 feet is the length of one side, square has 4.

So

11 * 4 = 44

The perimeter of a square (whose area is 121 feet) is 44 feet.

You design a new app for cell phones. Your revenue for x downloads is given by f(x) = 3x Your profit

Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

<u><em>means</em></u>

$p=90\% f\left( x\right) -20$

<u><em>means</em></u>

<u><em></em></u> $p=\frac{90}{100} \times f\left( x\right) -20$

<u><em>means</em></u>

$p=\frac{9}{10} \times (3x) -20$

<u><em>means</em></u>

$p=\frac{9}{10} \times (3x) -20$

<u><em>means</em></u>

$p=2.7x -20$

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223
