<h3>
Answer: 0.5</h3>
========================================================
Explanation:
The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.
We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.
This leaves sin(B)/b
We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.
The angle opposite side c is 15 degrees, so C = 15.
The lowercase letters represent side lengths, while the uppercase letters are angles.
--------------------------
We have enough to apply the law of sines to solve for side c.
sin(B)/b = sin(C)/c
sin(105)/2 = sin(15)/c
c*sin(105) = 2*sin(15) ............. cross multiply
c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)
c = 0.53589838486224
c = 0.5
Side c is roughly 0.5 cm long.
Make sure your calculator is in degree mode.

Step-by-step explanation:
Answer:
Percentage Profit is 63.63%
Step-by-step explanation:
The man buys 440 eggs at 55 pence a score
i.e. he buys 20 eggs for 55 pence
He buys 1 egg for 55/20 = 2.75 pence
Therefore, he buys 440 eggs for = 440 × 2.75 = 1210 pence
10% eggs are unsaleable
thus he sold = 440 - 440 × 10/100 = 440 - 44 = 396 eggs
Eggs sold in dozen = 396/12 = 33
He sold 1 dozen for = 60 pence
Thus, he sold 33 dozen for = 33 × 60 = 1980 pence
Profit = 1980 - 1210 = 770 pence
% Profit = (770/1210) × 100 = 63.63%
(hope this helps can i plz have brainlist :D hehe)
Answer:
1. The domain for the number of fruit cups is 0 minimum and 20 maximum.
[0 < x < 20].
2. [10 < y < 70]
Step-by-step explanation:
1. The domain is 0 to 20 because there are 20 people total who will each have a fruit cup
2. The range is $10 to $70 because the minimum price is $10 without any fruit cups and $70 when there are 20 fruit cups.
