Lots of points due today help

ok

Step-by-step explanation:

11) 75 percent. this is bc 32 - 8 is 24, and 24 of 32 as a percentage is 75 percent.

12) 25 percent, bc 15 percent of 60 is 25 percent

75%

75%

Step-by-step explanation:

11. 32-8=24 boys

24 boys / 32 in the class = 0.75

0.75 x 100 = 75 %

12. 45/60= 0.75 or 75%

(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
