The making of the candles is an illustration of unit rates
The minimum amount of wax the store owner needs to make 60 candles is 180 grams
<h3>How to determine the amount of wax needed</h3>
The number of candles is given as:
n = 60
The amount of wax needed for a candle is not given.
So, we make use of an assumed value.
Assume the minimum amount of wax needed to make a candle is 3 grams.
Then, the amount needed for 60 would be:
Amount = 60 * 3
This gives
Amount = 180
Hence, the minimum amount of wax the store owner needs to make 60 candles is 180 grams (using the assumed value)

Answer:
B = 40°
a = 23.0
b = 19.3
Step-by-step explanation:
✔️B = 180° - (90° + 50°) => sum of triangle
B = 40°
✔️Reference angle = 50°
Opp = a
Hypotenuse = 30
Adjacent = b
Find a by applying the trigonometric function, SOH:
Sin 50 = Opp/Hyp
Sin 50 = a/30
30 × Sin 50 = a
23.0 = a
a = 23.0 (nearest tenth)
To find b, apply CAH:
Cos 50 = Adj/Hyp
Cos 50 = b/30
30 × Cos 50 = b
b = 19.3 (nearest tenth)
B, try writing the numbers out and then looking at them.
