m(x) = - 2 (x - 6)² + 18 ← is in vertex form

Josh went to applebee and enjoyed a delicious steak. He enjoyed his server and wanted to give an extra special tip. Usually josh
Sonbull [250]

Answer:

Josh's total bill is $ 27.825

Step-by-step explanation:

Given:

The subtotal of the Josh Bill =   $21.00

<u>Finding the usual amount Josh gave as Tip To his sever:</u>

Usually josh tips 20% to all servers

So Tip = 20% of his subtotal

=> 20\% \times 21

=>\frac{20}{100} \times 21

=>0.2 \times 21

=>4.2

So Josh usually tips $4.2 to his server

<u>Finding the amount Josh gave 25%</u><u> </u><u>as Tip To his sever:</u>

But now he tips 25% which is

=> 25% of 21

=> \frac{25}{100} \times 21

=> 0.25 \times 21

=> 5.25

Thus the tip amount will be $5.25

So he will be giving (5.25 - 4.2) = $1.05 more than the usual tip

<u>Finding the total bill</u>

The total bill  = subtotal+ 7.5% sales tax +  25% tip

=> 21 + 7.5 % of 21 + 25% of 21

=> 21 + \frac{75}{100} \times 21 +  \frac{25}{100} \times 21

=>21 +0.075 \times 21 +  0.25 \times 21

=> 21 +1.575 +5.25

=>27.825

HELP ASAP:
tekilochka [14]

Answer:

Here's how I would do it.  

Step-by-step explanation:

If two triangles are similar, corresponding sides are in the same ratio.

We know the measures of b and a, so we can calculate the ratio b/a.

d and b are in the same ratio, so

\begin{array}{rcl}\dfrac{d}{c}& = & \dfrac{b}{a}\\d & = & c \times \dfrac{b}{a}\\\end{array}

We know the measures of c, b, and a, so we can calculate the value of d.
