Answer:
The percentage of the hot dog decreased by 20%
Step-by-step explanation:
20% of 2.50 is 50 cents, meaning that the price went down by 50 cents.
Hope this helps!
SOH = Sine Opposite Hypotenus
CAH = Cosine Adjacent Hypotenus
TOA = Tangent Opposite Adjacent
Based on the key I wrote above, TOA is what you will use. Starting from angle Z look at the opposite side and adjacent side. (Opposite = 21 and Adjacent = 20) Make sure you're not looking at the hypotenus which is the side that is always across from the 90° angle.
Going by opposite over adjacent, that would be 21/20
The answer is the first choice 21/20
You just add all of the weight of the contents together. 12 3/4+ 8 1/4 +7, which equals 28 pounds.
A = P(1+r%)ⁿ , where P = initial value, A= new value, n = number of years and
r% is the growth or depreciation rate, depending on its sign:
If it's a depreciation, the formula becomes:
A = P(1 - r%)ⁿ
500 = 15000(1-0.3)ⁿ
500/15000 = (0.7)ⁿ
0.033333 = 0.7ⁿ
ln(0.03333) = n.ln(0.7)
n = ln(0.03333)/ln(0.7)
n = 9.5 years
