2.	Numerator of a fraction is 5 more than its denominator. If 4 is added to numerator and denominator, the fraction obtained is 6/5. Find the fraction.
Answer» LET denominator = x So, Numerator = ( x + 5 ) $\mathbf{ \textcolor{red}{ \large{fraction \: = \frac{x + 5}{x} }}}$ ACCORDING to the question, if 4 is added to numerator and denominator, fraction BECOMES 6/5 $\mathbf{ \frac{x + 5 + 4}{x + 4} = \frac{6}{5} } \\ \\ \\ \rightarrow5(x + 9) = 6(x + 4) \\ \\ \rightarrow5x + 45 = 6x + 24 \\ \\ \rightarrow \: x \: = 21$ Hence, $\mathbf{fraction = \frac{x + 5}{x} = \frac{21 + 5}{21} = \frac{26}{21} }$

4.	The volume of a cone is 462 m³. Its base radius is 7 m. Find its height.
Answer» HI, ANSWER: height of cone 9 m. Solution: We KNOW that Volume of a cone is expressed as V = $\frac{1}{3} \times b \times h \\$ here b is base area. As base of a cone is circle,so area of base = $\pi {r}^{2}$ Now,the combine formula is given as V cone $= \frac{1}{3} \pi {r}^{2} h$ A.T.Q. V cone = 462 m³ Radius = 7 m $h = \frac{3 \times volume}{\pi {r}^{2} } \\ \\ h = \frac{3 \times 462}{3.14 \times 49} \\ \\ \\h = \frac{1386}{153.9} \\ h = 9.0058 \: m \\ \\ or\\ h = 9 \: m$ hope it helps you.

a bell rings at every 6 seconds. a second bell rings at every 8 seconds. a third bell rings at every 10 seconds. if all the three bells ring at the same time at 9o clock in the morning, at what time will they all ring together again

Answer»

Answer:

At 9:00:02 AM will they all ring together again.

Step-by-step EXPLANATION:

Given : A bell rings at every 6 seconds. a second bell rings at every 8 seconds. a third bell rings at every 10 seconds. If all the three BELLS ring at the same time at 9'o clock in the morning.

To find : At what time will they all ring together again?

Solution :

First we find the LCM of bell rings i.e. 6,8,10

$6=<klux>2</klux>\times 3$

$8=2\times 2\times 2$

$10=2\times 5$

$LCM(6,8,10)=2$

Which means after 2 seconds bell rings.

i.e. At 9:00:02 AM will they all ring together again.

Divide the polynomial (x² + 4x + 4) by the binomial (x + 2). What is the quotient and remainder?

Answer»

ANSWER : remainder = 0 and QUOTIENT = (x + 2)

EXPLANATION : POLYNOMIAL (x² + 4x + 4) is divided by another polynomial (x + 2).

we have to find quotient and remainder.

first of all, resolve (x² + 4x + 4) into SIMPLER form,

x² + 4x + 4 = x² + 2.2.x + (2)²

we know, from algebraic identity, (a + b)² = a² + 2ab + b²

so, x² + 2.2.x + (2)² = (x + 2)²

now, (x² + 4x + 4) = (x + 2)² is divided by (x + 2)

i.e., (x + 2) ) (x + 2)² ( (x + 2)

(x + 2)²

----------------------------------------

0

so, remainder = 0 and quotient = (x + 2)
