Divide ₹1100 among A,B and C in the ratio 2:3:5

Answer»

HEY!!!


Let the common MULTIPLE be x


Therefore,

2:3:5 = 2X, 3x & 5x


As per condition,


2x+3x+5x = 1100


10x = 1100


x = 1100/10


x = 110



Therefore,


2x = 2×110


=220



3x = 3×110


= 330



& 5x= 5×110


= 550


Therefore, A gets ₹220; B gets ₹330 & C gets ₹550.

Please solve this question ... Find the values of x and y .

Answer»

Hey mate here is your answer.....

X^2 +y^2 -2x +4y +5=0

=>x^2-2x +1+y^2+4y+4=0

=>(x-1)^2+(y+2)^2=0


Now we KNOW that if the sum of two perfect

squares is 0 , then they are INDIVIDUALLY 0.

so, x-1=0

=>x=1

And, y+2=0

=>y=-2.

so, the value of x is 1 and that of y is -2.

It is being that 1 is a zero of the polynomialFind its other zeroes

Answer» LET a and b be other zeros
hence
sum of zeros
=  \frac{ - b}{a}  \\  = 0
and PRODUCT of roots
=  \frac{ - d}{a}  \\  =  \frac{6}{ - 1}  \\  =  - 6
hence
a + b + 1 = 0 \\ ab = -  6
solving this
we get
a =  - 3 \\ b = 2

Formula of percentile

Answer»

I think :

The formula for calculating PERCENTILE ranks is relatively simple and straightforward. Knowing only the distribution of scores, you can easily calculate the percentile rank for any of the scores in the distribution. The percentile rank formula is: R = P / 100 (N + 1). R represents the rank order of the score.




formula for percentile in statistics:


The median is the 50th percentile: the point in the data where 50% of the data fall below that point, and 50% fall above it. To calculate the kth percentile(where K is any NUMBER between zero and one hundred), do the following steps: Order all the values in the data set from smallest to largest.




formula for percentile in excel:


Click on cell "A1" and enter the values in your data set into the cells in column A. Enter the following formula into the cell, excluding quotes: "=PERCENTILE.EXC(A1:AX,k)" where "X" is the last row in column "A" where you have entered data, and "k" is thepercentile value you are looking for.

If many paintings does jill own? (1) if jill sells 5 of her paintings then she will own fewer than 24 paintings. (2) if jill buys 5 more paintings then she will own at least 32 paintings.

Answer»

Set-up equations

x - 5 = 24

x + 5 = 32

Combine

x-5+x+5= 56

-5 + 5 = 0

2x = 56

Solve for x

2x/2 = x

56/2 = 28

Answer

x = 28

The sides of a triangle are in the ratio 1/2 1/3 1/4 its perimeter is 54cm

Answer» HI MATE!!!

LET the SIDES be x/2, x/3,x/4

( x/4 )+( x/3 )+ (x/2) = 54

(3x/4) + ( x/3 ) =54

(13x/12 ) = 54

13x = 54×12

x = 49.98cm

The sides of an equilateral triangle are increasing at the 2cm per sec.Find the rate at which the area increases when the side is 10cm.

Answer»

Side of equilateral ∆ = 10cm.

AREA of equilateral ∆ = √3 a^2 /4 sq.units.

Area of first ∆ = √3 10^2/4 sq. Cm.

= 25√3 sq. Cm.

Side INCREASED by 2 cm. New side=12cm.

Area of second ∆ = √3 12^2 /4 sq. cm.

= 36√3 sq. Cm.

Increase in area

= 36√3 - 25√3=11√3sq.cm.per second

Rate of increase in area

(% in increase) = 11√3 X 100 / 25√3

= 44% per second

✨✨ Hello Friends. Please Answer This Question ✨✨➡️ Find the least perfect square number exactly divisible by 8, 15, 20, 25.

Answer»

To FIND this we need to find the LCM of 8, 15, 20 and 25 which is 1800

Prime factorisation of 1800 is 2*2*2*3*3*5*5

We see that 2 is not in a pair. So 1800 is not a PERFECT square so we need to multiply it by 2 to obtain the answer.

1800*2 = 3600

3600 is the answer.
