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”

means

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

means

$p=\frac{90}{100} \times f\left( x\right) -20$

means

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

means

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

means

$p=2.7x -20$

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223

The dimensions of a conical funnel are shown below:

jasenka [17]

Volume of a conical funnel = π r² h/3
v = 3.14 * (2in)² * 6in/3
v = 3.14 * 4in² * 2in
v = 25.12 in³

25.12 in³ ÷ 10 in³ per minute = 2.512 minutes

It will take 2.51 minutes for all the liquid to pass through the nozzle.
