A bill for Rs 3235 was drawn on Feb. 3, 1998 at 6 months and discounted on March 3, 1998 at 8 % p.a. Find the value of the bill
Fantom [35]

Answer:

RS 3127.166

RS 107.834

Step-by-step explanation:

6 month bill :

Drawn date = Feb, 3

Discounted date = March 3,

Difference = 1 month

6 month - 1 month = 5 months = 5 * 30 = 150 days

Value of the bill :

P(1 - rate * time)

3235(1 - 0.08 * 150/360)

3235(1 - 0.08 * 0.4166666)

3235(1 - 0.0333333)

3235(0.9666666)

= Rs3127.1666

Value of bill = 3127.166

Bankers gain = 3235 - 3127.166 = 107.834

A man bought a beautiful horse and needed a paddock to keep it in. He decided on a square shaped area and used 30 poles on each
Aleks04 [339]

Answer:

120poles

Step-by-step explanation:

Given

Length of each poles of the paddock = 30

Since a square has 4 sides, the perimeter of the square shaped paddock is what we are to look for.

Perimeter of a square = 4L

L is the length of each side of the paddock

Perimeter = 4(30)

Perimeter of the square = 120

Hence he used 120poles for the paddock

Given that f(x)= 9x^2-180, find x
hoa [83]
9x^{2}  - 180 = 0

9x^{2}  = 180

Divide both sides by 9

 x^{2} = 20

Square root both sides, and you get

x =  \sqrt{20} --\ \textgreater \  simplified: 2 \sqrt{5}
