Step-by-step explanation:

Use Compound Intrest Formula

$a = p(1 + \frac{r}{n} ) {}^{nt}$

where p is the original amount.
R is the amount of percentage compounded
N is amount of times compounded per year.
T is how long the interest last.

P is 400,00p

T is 12% or 0.12

N is 4 since it is compounded quarterly

T is 5.

Plug the values in

$400000(1 + \frac{0.12}{4} ) {}^{20}$

Ypu get

$722444.49386776

ASHA 777 [7]

Answer: " b = 3 ⅕ ; or, write as: 3.2 .
_____________________________________
Given: "A = (1/2) * b * h " ;

↔ A = (b * h) / 2

2A = (b*h) ;

2A/ h = b ;

↔ b = (2A) / h ;

Given A = 48 ; and h = 30 ; Plug in these values; and solve for "b" ;

→ b = (2*48) / 30 ;

= 96/30 ;

= (96÷6) / (30÷6) ;

→ b = 16/5 ; = 3 ⅕ ; or, write as: 3.2 .
