Please help me please :(

18

Step-by-step explanation:

There is a string that is 3 yards long that is divided into pieces that are 1/6 of yard long.  Divide the total length by the length it was divided into to find the number of pieces.

When dividing with fractions, the second number will be inverted and multiplied by the first number.

3 ÷ (1/6) = 3 × 6 = 18

You will have 18 pieces

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

(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
