Answer» $\huge\bold{HEY:)-}$ ⭐⭐⭐⭐⭐⭐ ⭐ ⭐ ⭐ ⭐ ⭐ ❤❤❤⭐⭐⭐⭐ $\\ \\ \\ \\ \\$ ⤵⤵⤵⤵ FOLLOW , BRAINLIST ME☺☺PLZZ =========== Answers Golda Ace Solution:- Given : AB = 12 cm, BC = 16 cm and AB is ⊥ to BC Now, applying Pythagoras Theorem, Hypotenuse² = Perpendicular² + Base² ⇒ AC² = AB² + BC² ⇒ AC² = 12² + 16² ⇒ AC² = 144 + 256 ⇒ AC² = 400 ⇒ AC = √400 AC = 20 cm There is a relation between Hypotenuse (AC) and CIRCUMRADIUS (r). The hypotenuse is the diameter of the circle and, and its CENTER is exactly the midpoint of the hypotenuse. So, Hypotenuse = 2r Therefore, r = hypotenuse/2 r = 20/2 Radius of the circle = 10 cm Answer.

Golda Ace

Solution:-

Given : AB = 12 cm, BC = 16 cm and AB is ⊥ to BC

Now, applying Pythagoras Theorem,

Hypotenuse² = Perpendicular² + Base²

⇒ AC² = AB² + BC²

⇒ AC² = 12² + 16²

⇒ AC² = 144 + 256

⇒ AC² = 400

⇒ AC = √400

AC = 20 cm

There is a relation between Hypotenuse (AC) and CIRCUMRADIUS (r).

The hypotenuse is the diameter of the circle and, and its CENTER is exactly the midpoint of the hypotenuse.

So, Hypotenuse = 2r

Therefore,

r = hypotenuse/2

r = 20/2

Radius of the circle = 10 cm

Thier are 255857 persons visited in a zoo in a week . How many people visited the zoo in 2 days

Answer»

Answer:

The number of peoples visited Zoo in 2 days is 73102.

Step-by-step explanation:

Numbers of people visited Zoo in 7 days (a week)= 255857 peoples

So, The number of people visited Zoo in one day = 255857/7

= 36551

Hence, 36551 peoples visit Zoo in one day.

So, in TWO days, people visit= Number of people visit in one day × 2 days

= 36551 × 2

= 73102

Therefore, The number of peoples visited Zoo in 2 days is 73102.

Show that only one out of a a+2 and a+4 is divisible by 3

Answer»

ANSWER:

Step-by-step explanation:

let a be any positive integer and b=3

a =3q+r

where q is the quotient and r is the remainder

0_

so the REMAINDERS may be 0,1 and 2

so a may be in the FORM of 3q, 3q=1,3q+2

CASE-1

IF A=3q

a+4=3q+4

a+2=3q+2

here a is only DIVISIBLE by 3

CASE 2

if a = 3q+1

a+4=3q+5

a+2=3q=3

here only a+2 is divisible by 3

CASE 3

IF a=3q+2

a+2=3q+4

a+4=3q+2+4

=3q+6

here only a+4 is divisible by 3

HENCE IT IS JUSTIFIED THAT ONE AND ONLY ONE AMONG a,a+2,a+4 IS DIVISIBLE BY 3 IN EACH CASE.

y = (10-x)

:

" if 18 be subtracted from it, the digits in the resulting number will be equal."

10x + y - 18 = 10z + z10x + y = 11z + 18

:

SUBSTITUTE (10-x) for y

10x + (10-x) = 11z + 18

10x - x = 11z + 18 - 10

9x = 11z + 8

:

The single digit integer values for x and z are limited to x=7 and z=5 in this equation:

x = 7, y = 3, z = 5

:

The number is 73

:

Check in the statement:

"if 18 be subtracted from it, the digits in the resulting number will be equal."

73 - 18 = 55

Answer» assume that 5-2 root 3 is rational 5-2 root 3 = a/b , where a and b are integers . -2 root 3 = a/b - 5 2 root 3 = 5 - AB 2 root 3 = 5b/b - a/b root 3 = 5b - a / 2b we know that a, b , 2 and 5 are integers and they are also rational THEREFORE root 3 will be rational but we know that root 3 is irrational there is a contradiction so, 5 - 2 root 3 is an irrational number hope it HELPS

Prove 5-2root3 is an irrational no

Answer»

assume that 5-2 root 3 is rational

5-2 root 3 = a/b , where a and b are integers .

-2 root 3 = a/b - 5

2 root 3 = 5 - AB

2 root 3 = 5b/b - a/b

root 3 = 5b - a / 2b

we know that a, b , 2 and 5 are integers and they are also rational

THEREFORE root 3 will be rational

but we know that root 3 is irrational

there is a contradiction

so, 5 - 2 root 3 is an irrational number
