Solution:

To make CONCRETE he needs to mix cement, sand and gravel in the ratio 5:4:1 by weight.

Let the cement , sand and gravel NEEDED be 5x , 4x and 1x

HENRY needs to make 110 kg of concrete.

5x + 4x + 1x = 110 kg

10x = 110

x = 11

So,

Cement needed = 5x = 5 * 11 = 55 kg

Sand needed = 4x = 4 * 11 = 44 kg

Gravel needed = 1x = 1 * 11 = 11 kg

Henry is having 50 kg of cement, 55 kg of sand and 15 kg of gravel.

And Henry needs 55 kg of cement, 44 kg of sand and 11 kg of gravel.

This clearly shows that Henry is having a shortage of Cement.

HYY Dude

On the number line the 3 digit NUMBERS are : 100 - 999 So if I would start at 1 - 999 then I have 999 numbers in TOTAL. from those I will take away the one digit numbers : 9 and the two digit numbers: 90 I.e: 999-99 = 900 3 digit numbers.

Answer:

Step-by-step explanation:

1. (i) 225 = 135 x 1 + 120

  135 = 120 x 1 + 15

   120 = 15 x 8 +0

∴ HCF ( 225,135 ) is 15.

(ii) 38220 = 196 x 195 + 0

∴ HCF ( 38220,196 ) is 195.

(iii) 867 = 225 x 3 + 102

     225 = 102 x 2 + 51

      102 = 51 x 2 + 0

∴HCF ( 867,225 ) is 51.

2. Any odd positive integer is ALWAYS of the form (2M + 1) → 1

Let a be the positive odd integer which when divided by 6 gives Q as quotient and r as remainder.

according to Euclid's division lemma

a = bq + r

⇒ a = 6q + r

where r = 0 , 1 , 2 , 3 , 4 , 5

∴When r = 0,

a = 6q + 0

  = 2(3q)

⇒it is an even no as it is of the form 2m where m = 3q.

When r = 1

a = 6q + 1

= 2(3q) + 1

⇒it is an odd no as it is of the form 2m + 1 where m = 3q.

When r = 2

a = 6q + 2

= 2(3q + 1)

⇒it is an even no as it is of the form 2m where m = 3q + 1

When r = 3

a = 6q + 3

a = 6q + 2 + 1

= 2(3q + 1) +1

⇒it is an odd no as it is of the form 2m + 1 where m = 3q+1

When r = 4

a = 6q + 4

= 2(3q + 2)

⇒it is an even no as it is of the form 2m where m = 3q + 1

When r = 5

a = 6q + 5

a = 6q + 4 + 1

= 2(3q + 2) +1

⇒it is an odd no as it is of the form 2m + 1 where m = 3q+2

∴ Hence proved.

3.To get the maximum number column here we always FIND HCF and for minimum number we find LCM

So can use Euclid’s algorithm to find the HCF.

Here 616> 32 so always divide greater number with smaller one

When we divide 616 by 32 we get quotient 19 and remainder 8

So we can write it as

616 = 32 x 19 + 8

32 = 8 x 4 + 0  

As there are no remainder so our HCF will 8.

4. Let us take α as any positive integer and B = 3.

Then using Euclid’s algorithm we get a = 3q + r  here r is remainder and value of q is more than or equal to 0  and r = 0, 1, 2 because 0 < r < b  and the value of b is 3 So our possible values will 3q+0 , 3q+1 and 3q+2

Now find the square of values  

Use the formula (a+b)² = a² + 2ab +b² to open the square bracket  

(3q)² = 9q²  

if we divide by 3 we get no remainder  

we can write it as 3*(3q²)  so it is in form of 3m  here m = 3q²

(3q+1)² = (3q)² + 2 x 3q x 1  + 1²        

=9q² + 6q +1 now divide by 3 we get 1 remainder

so we can write it as 3(3q² + 2q) +1 so we can write it in form of 3m+1 and value of m is 3q² + 2q  here

(3q+2)² = (3q)² + 2*3q*2  + 2²  

=9q² + 12q + 4

now divide by 3 we get 1 remainder

so we can write it as 3(3q² + 4q +1) +1 so we can write it in form of 3m +1 and value of m will 3q² + 4q +1

Square of any positive integer is either of the form 3m or 3m + 1 for some integer m.

∴ Hence proved.

5.According to Euclid’s Division Lemma

Let take a as any positive integer and b = 9.

Then using Euclid’s algorithm we get  a = 9q + r  here r is remainder and value of q is more than or equal to 0  and r = 0, 1, 2, 3, 4, 5 , 6 , 7 , 8, because 0 ≤r < b  and the value of b is 9

Sp possible forms will  9q, 9q+1, 9q+2,9q+3,9q+4,9q+5,9q+6,9q+7 and 9q+8

to get the cube of these values use the formula

(a+b)³           = a³ + 3a²b+ 3ab² + b³

In this formula value of a is always 9q

So plug the value we get

(9q+b)³          = 729q³ + 243q²b + 27qb² + b³

Now divide by 9 we get quotient = 81q³ + 27q²b + 3qb²  and remainder is b³

So we have to consider the value of b³

b = 0

 we get 9m+0  = 9m

b = 1

then  1³  = 1 so we get  9m +1

b = 2

then 2³ = 8 so we get 9m + 8

b = 3

then 3³ = 27  and it is divisible by 9  so we get 9m

b = 4

then 4³ =64 divide by 9 we get 1 as remainder so we get 9m +1

b=6  

 then 6³=216 divide by 9 no remainder there so we get 9m

b=7

then 7³ = 343 divide by 9 we get 1 as remainder so we get 9m+1

b=8

 then 8³ = 512 divide by 9 we get 8 as remainder so we get 9m+8

∴ All values are in form of 9m , 9m+1 or 9m+8 .

13.The fundamental theorem of arithmetic states that every positive integer (except the number 1) can be represented in exactly one way apart from rearrangement as a product of one or more primes This theorem is also called the unique factorization theorem.
