Answer:
Step-by-step explanation:
Angle C is ...
C = 180° -A -B = 180° -60° -30° = 90°
This is a right triangle with hypotenuse length 14.
a = c·sin(A) = 14·sin(60°) = 7√3
b = c·sin(B) = 14·sin(30°) = 7
The remaining sides are b=7 and a=7√3.
Answer:
The area after 9 years will be 1,234 km^2
Step-by-step explanation:
In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.
To answer this question, we shall be using an exponential approximation.
Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.
This can be written as;
A = I(1-r)^t
where A is the new area we are looking for
I is the initial area which is 1700 according to the question
r is the rate of decrease which is 3.5% = 3.5/100 = 0.035
t is time which is 9 years according to the question
We plug these values and have the following;
A = 1700(1-0.035)^9
A = 1700(0.965)^9
A = 1,233.66
This is 1,234 km^2 to the nearest square kilometer

Answer:
We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):
0.30*50 = 15 g
There are 15 grams of cocoa in the chocolate bar.
