If Valerie deposited 12,000 into an account threat earns 15% simple annual interest how much money will she have after 3 years
Ad libitum [116K]

Answer:

The amount which she will have into account after 3 years is  17,400  unit

Step-by-step explanation:

Given as :

The principal which is deposited into an account = 12,000  unit

The rate of interest simple annual = 15%

The Time period = 3 years

Let The amount which she have after 3 years = A  unit

<u>From simple Interest method</u>

Simple Interest = \frac{Principal\times Rate\times Time}{100}

Or , Simple Interest = \frac{12,000\times 15\times 3}{100}

Or,  Simple Interest = \frac{540,000}{100}

∴    Simple Interest = 5,400  unit

Now,

Amount = Principal + Simple Interest

Or, A =  12,000  unit + 5,400  unit

∴   A =  17,400  unit

Hence The amount which she will have into account after 3 years is  17,400  unit . Answer

4. An airplane at T(80,20) needs to fly to both U(20,60) and V(110,85). What is the shortest possible distance for the trip?
damaskus [11]
The distance formula for two points in a plane is 
D=sqrt( (x1-x2)^2 + (y1-y2)^2 ) 
 From T to U
 D= sqrt((80-20)^2 + (20-60)^2) = 72.11 
 Then flying from U to V
 D= sqrt((20-110)^2 + (60-85)^2) = 93.4 
 So T to U to V = 72.11+93.4 = 165.5 
 BUT checking also T to V to U
 From T to V
 D= sqrt((80-110)^2 + (20-85)^2) = 71.6
 Then from V to U
 D= sqrt((110-20)^2 + (85-60)^2) = 93.4 
 So from T to V to U = 165
 Pretty much the same both directions
 So yes the answer is A
