14.	Why mathematicians use radicals instead of decimals?For instance: √350 in exact form is: 5√14: While in decimals its: 18.708So why not use 18.708 over 5√14 since both will yield the same result?
Answer» In most of the cases, calculations become easier when decimals are AVOIDED. For EG, if radius of CIRCLE is given as 7 cm and you are asked to find the area, you USE π=22/7 instead of 3.14, you're free to use anything but why to make things complicated rather than keeping it simple? Secondly, another disadvantage of using decimals is most of the times, the decimals are of the TYPE non-repeating recurring. Lets take the same example again, π = 3.14159265358979323846, this is never ending. Hence, 22/7 is short, sweet and simple. Hope it helps!!! :)

The average of boys is 18 years in a class of 30 if 10 more boys jion the class the average of the whole class gets increasedby a years what is the average age of newcomers

Answer»

ANSWER:

let sum of age of 30 students of class = x

then AVERAGE of these 30 students = x / 30

also average given = 18

so x/30 = 18

solving for x gives = 18 * 30

x=540

let sum of age of NEW 10 students = y

average of these 40 students = (x+y) / 40

also average of these 40 students = 19

putting value of x = (540 + y) / 40

solving for y = (540 + y) / 40 = 19

540+y = 40 * 19

540 + y = 760

y = 220

then average of these 10 students = ( sum of their age) / 10

average = y/10

average = 22

What is the equation of the line perpendicular to the line 2x + 3y= -6 and having y-intercept 3?

Answer»

Answer:

2y = 3x + 6

Step-by-step explanation:

Slope of line 2X + 3y = -6 is -2/3 (m')

Let slope of other line be m"

If two lines are parallel, then the PRODUCT of their SLOPES is -1

m'm"= -1

-2/3 .m" = -1

m" = 3/2

One point on this line is given, i.e., (0,3)

So, by Slope intercept form

y-y' = m"(x-x')

y-3 = 3/2 . (x-0)

2y - 6 = 3x

2y = 3x + 6
