(a) Find the principal after 1 month.
$

(b) Find the principal after 6 months.
$

(c) Find the principal after 1 year.
$

(d) Find the principal after 20 years.
$

a.  $1010.83

b.$1066.77

c. $1138.00

d.$13,269.22

Step-by-step explanation:

Given the annual rate as 13%(compounded monthly) and the principal amount as $1000.

a. #first we calculate the effective annual rate;

The compounded amount after 1 month is therefore:

Hence, the principle after one month is $1010.83

b. The principal after 6 months:

-From a above we have the effective annual rate as 0.1380 and our time is 6 months:

Hence,  the principal after 6 months is $1066.77

c.The principal after 1 year:

-From a above we have the effective annual rate as 0.1380 and our time is 12 months:

Hence,  the principal after 1 year is $1138.00

d. The principal after 20years:

-From a above we have the effective annual rate as 0.1380 and our time is 20yrs:

Hence,  the principal after 20 years is $13,269.22

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^
