Answer:

Step-by-step explanation:

Sin 45 = y/(11√6)

1/√2 = y/(11√6)

y= (11√6)/√2

y= 11√3

tan 60 = x/y

√3 = x/y

x = y√3

= (11√3)√3

= 11(3)

= 33

You leave a 15% tip of $3.12. How much was the bill?

Answer:

$3.61 cents

Step-by-step explanation:

Given the following question:

15% of 3.12

To find the answer we use the formula to calculate percentages, then we add that answer to the initial bill.

$\frac{p\times n}{100}$
$\frac{15\times3.12}{100} =15\times3.12=46.8\div100=0.468$
$=0.468$

<u>Round:</u>
$0.468$
$8 > 5$
$0.47$
$t=0.47$

<u>Now add:</u>
$3.14+0.47=3.61$
$=3.61$

After leaving a 15% tip, the total amount you would pay is "$3.61 cents."

Hope this helps.
