Write a descriptive paragraph on 'An Old age Home' with the help of the given hints and along with your own ideas write the paragraph in about 120 words.​

Given:

A : B = 7 : 8

B : C = 9 : 10

C : D = 11 : 12

B = 1584

To find:

A + B + C + D

Solution:

Converting ratios into fraction, we will get these 3 equations

[tex]A/B= 7/8 \\B/C = 9/10\\C/D = 11/12[/tex]

Put the value of B and solve for A in the first equation.

[tex]A/1584= 7/8\\[/tex]

Multiply both sides by 8

[tex]8A/1584=7\\A/198=7\\[/tex]

Multiply both sides by 198

[tex]A= 1386[/tex]

Now put the value of B in 2nd equation and solve for C

[tex]1584/C =9/10[/tex]

Multiply both sides by 10C

[tex]15840=9C\\C=15840/9\\C=1760[/tex]

Put the value of C in 3rd equation and solve for D

[tex]1760/D=11/12[/tex]

Multiply both sides by 12D

[tex]21120=11D\\D=21120/11\\D=1920\\[/tex]

Now that we have the value of A, B, C, and D add them up to get the answer.

[tex]1386+1584+1760+1920\\=6650[/tex]

Therefore, A + B + C + D = 6650

Answer:

a:b=7:8,b:c=9:10,c:d=11:12

a:b:c:d=7×11×9:8×11×9:10×11×8:

152×10×8

b=792x=1584

x=

a+b+c+d= 2(693+ 792+ 880+960)

=6650

Image persists at our retina for 1/16th of second . It is called persistence of vision.

Answer: Persistence of vision is an optical phenomenon where the illusion of objects motion is created because the brain interprets multiple still images as one overlapping another signal of views.

Explanation:

In generally, everything that seems to be in motion and observed as blur could be regarded "persistence of vision".

After the object is removed, the impression or visualization of an object seen by the human eye remains in his memory for for 1/16th of a second. If we see another object before this time the visual of that object disappeared from view. This is an optical illution.
