A student answered 38 problems on a test correctly and received a grade 95%. How many problems
were on the test, if all the problems were worth the same number of points

40 questions

Step-by-step explanation:

set it up as an equation

38/x = 95/100

cross multiply

95x=3800

solve for x

x=40

(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
