Let be the surface area of 1st sphere and 2nd sphere are 1x and 2x respectively. Then, According to the area of sphere we have, 4πr²=1x. ...(i) And, Similarly, 4πR²=2x ....(ii) From (i) and (ii) equation, (r/R)²=1/2 Hence, R=√2r ....(iii) Now the volume of 1st sphere is 4/3πr³ ....(iv) And, Volume of 2nd sphere is 4/3π(R)³ .....(v) Now put the value of R from (iii) in (v) such that, 4/3π(√2r)³ =4/3π2√2³ = 8√2/3πr³ ....(vi) Now from iv and vi we conclude the ratio of the volumes of given spheres, =1:2√2

Sia ? 4 years, 5 months ago

Given : number should be possible to be constructed from any date of the year by adding the number of the month to the number of the day. with that logic, December 21st would become the number 33, since December is the twelfth month, and 21 + 12 = 33. March 23 would become 26, and so on.

To Find :how many different numbers can be made using dates of a regular calendar.
a. 28
b. 34
c. 42
d. 18​

Solution:
January has 1 to 31 days and month 1 Hence
from 2 to 32
December has 1 to 31 days month 12 Hence
from from 12 to 43
Hence all possible numbers are from
2 to 43
Which counts to be 42
Hence 42 is correct answer
42 different numbers can be made using dates of a regular calendar.

x=23.426... eq.1 1000x=23426.426 1000x=23403+23.426 1000x=23403+x 1000x-x=23403 999x=23403 x=23403/999...eq.2 Putting value of x in eq.2 23.426=23403/999

Anubhav Yadav 4 years, 5 months ago

x=23.426.....(i) 1000x=23426.426 1000x=23403+23.426 1000x=23403+x 1000x-x=23403 999x=23403 x=23403/999......(ii) Putting value of x in (ii) So,23.426=23403/999

Let x = 23.426 (bar on 426) ..... (i) Then, 10x = 234.2666.... ..... (ii) 1000x = 23426.6666.... ...... (iii) Subtracting iii from ii 1000x - 10x = 23426.6666 - 234.2666 990x = 23192.4 x = 231924 / 9900 = 19327/825 Hope it will be right !!

Let A(x1, y1), B(x2, y2) and C(x3, y3) be the vertices of a given triangle as shown in figure.

Now, (3,4) is the mid-point of AB, therefore,
{tex}3=\frac{x_1+x_2}{2}\ {/tex}and {tex}4=\frac{y_1+y_2}{2}{/tex}
x1 + x2 = 6 and y1 + y2 = 8 ..... (i)
(2,0) is the mid-point of BC, then,
{tex}2=\frac{x_2+x_3}{2}{/tex} and {tex} 0=\frac{y_2+y_3}{2}{/tex}
x2 + x3 = 4 and y2 + y3 = 0 ..........(ii)
(4,1) is the mid-point of AC, then,
{tex}4=\frac{x_1+x_3}{2}{/tex} and {tex}1=\frac{y_1+y_3}{2}{/tex}
x1 + x3 = 8 and y1 + y3 = 2 .........(iii)
Subtracting (ii) from (iii), we get,
x1 - x2 = 4 and y1 - y2 = 2 ........ (iv)
Adding (i) and (iv), we get,
2x= 10 and 2y= 10
x1 = 5 and y1 = 5
From (i), we have,
x2 = 6 - 5 = 1 and y2 = 8 - 5 = 3
From (ii), we have,
x3 = 4 - 1 = 3 and y3 = 0 - y2 = 0 - 3 = -3
Thus (5, 5), (1, 3) and (3, -3) are the vertices of triangle.
