The compound interest formula is : 
where, A= Future value including the interest,
P= Principle amount, r= rate of interest in decimal form,
t= number of years and n= number of compounding in a year
Here, in this problem P= $ 51,123.21 , t= 20 years and 2 months
So, t= 20 + (2/12) years
t= 20 + 0.17 = 20.17 years
As the amount is compounded daily, so n= (12×30)= 360 [Using the traditional Banker’s rule of 30 days per month]
Thus, 
When the interest rate is given, then we can use this equation for finding the future value.
Answer:
90 degrees, 60 degrees and 30 degrees
Step-by-step explanation:
90/3 = 30
30 x 2 = 60
Complete question is;
An architect plans to build an extension to meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 4(x+8) represents the area of the deck, where 4 is the width, in meters, and (x+8) represents the extended length, in meters. Use distributive property to write an expression that represents the total area of meilings new deck.
Answer:
4x + 32
Step-by-step explanation:
We are told that the expression 4(x+8) represents the area of the deck.
Also, that 4 is the width, in meters, and (x+8) represents the extended length, in meters.
Thus, area is;
A = 4(x+8)
Using distributive property simply means we will distribute the term outside the bracket to each term inside the bracket.
Thus;
A = (4 * x) + (4 × 8)
A = 4x + 32
Answer:
10x9-5(8)=34
Step-by-step explanation:
Cross mutiply. 42*10= 420. 14*g= 14g
14g= 420
divide by 14 for both sides
14g/14= 420/14
g= 30
Check answer by using substitution method
42/30. Divide by 3 . 42/3= 14 , 30/3= 10
14/10 and 14/10 equal to each other by dividing 2.
14/2= 7 , 10/2= 5
7/5= 7/5
Answer: g= 30
