If a bag contains 10,500 ounces (oz) of sand, about how many pounds (lb) does it contain? [1 pound= 16 ounces] a: 656.25 lb b: 1,500.75 lb c: 105,000 lb d: 168,000 lb

A: 656.25 lb

The bag contains 656.25 lb of sand.

Step-by-step explanation:

Given: A bag contains sand = 10,500 ounces

Also , 1 pound = 16 ounces.

Therefore to convert the given value to pounds, we need to divide the given value of ounces by 16, we get

Hence, the bag contains 656.25 lb of sand.

(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
