If she is purchasing 7.55 feet of butcher paper and the paper cost 1.89 dollars per foot:
7.55*1.89
=14.2695
round to the nearest cent:
14.3
Thus, the total cost would be $14.3 or $14.30
equation:
7.55 x $1.89 = about $14.30
Answer:
x ≈ 8.66
Step-by-step explanation:
Using the sine ratio in the right triangle
sin60° =
= 
Multiply both sides by 10
10 × sin60° = x, thus
x ≈ 8.66 ( to 2 dec. places )
