Dan ate at Applebee's and his check was 25.75. He wanted to leave a 20% tip. What was the total amount he paid for dinner?

$30.90

Step-by-step explanation:

1st way:

20% of $25.75 = $5.15

Add $25.75 and $5.15 together = $30.90

2nd way:

100% + 20% = 120%

120% of $25.75 = $30.90

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
