12) 8 liters in total. each glass holds 1/5 of a liter. 8 x 5 = 40 glasses.
13) 3bars/4people = 3/4 of a bar.
14) same concept as 13. .5quart/3people = (1/6) of a quart of milk.
15) 3 yards in total. divides it into pieces that are 1/4 yard long. so each 1 yard makes 4 pieces. that means 3 yards makes 12 pieces in total.
Find the cosine ratio of angle ΘΘ. Hint: Use the slash symbol ( / ) to represent the fraction bar and enter the fraction with no spaces. (4 points)
Cosine=adjacent/hypotenuse
adjacent=8
Hypotenuse =17
cosΘ=8/17
921÷ 2 = 460.5
which means the remainder is 1
So; the answer is 1
