Answer:
B. 39.59
Step-by-step explanation:
So 43 degrees, you know the length of the opposite side (27) and the angle (43 degrees), the only unknown is the hypotenuse. So you're looking for a trigonometric ratio that uses the angle (all of them do, except technically the inverse don't), the opposite side, and the hypotenuse. Sine is defined as
. So let's plug in known values:

Multiply both sides by x

divide both sides by sin(43)

Normally I would use a calculator, but in this case I'll use the approximation given in the problem of 0.682

simplify the fraction

Answer:
$2.20
Step-by-step explanation:
11 pounds of rice for $5.
Divide the $5 by 11.
11 divided by 11 is 1.
So 1 pound of rice is $2.20.
(PS i might be wrong, SO SORRY IF I AM)
It is 3 73/99
I just used a fraction calculator lol
You can simplify the fraction to get 2/5. If you convert this into a decimal you will get 0.4, so D is your answer.
