QUESTION 2

(10 Marks)

a) Find the amount on Simple Interest when N$ 4000 is lent at 5% p. a for 5

years. (2 Marks)

b) Find the compound interest on N$ 4500 for 3 years at 6% per annum.

(2 Marks)

c) In case interest is paid half yearly, then the interest is divided by 2, and used

as (R/2) in the formula and the time is multiplied by 2, and used as 2T in the

formula, given by A=P( 1+ (R/200))2T. (2 Marks)

d) In the case interest is paid quarterly, then the interest is divided by 4, and

used as (R/4) in the formula and the time is multiplied by 4, and used as 4T in

the formula, given by A=P(1+(R/400))4T payable quarterly (rate=R/4,

time=4T) (4 M​

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

i think the length is 12 and the width is 17

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
