Answer:
10
Step-by-step explanation:
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%
b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
Area of triangle ABC = 80 square units
Step-by-step explanation:
We need to find the area of triangle ABC when we are given:
a= 15, b=12 and C=63°
We can find area of triangle using SAS (Side Angle Side)
The formula used is:
We are given a= 15, b=12 and C=63°, Putting values in the formula
Solving
So, Area = 80.19
Rounding off to nearest whole number:
Area = 80 square units
