4.Prove that the product of two odd numbers is odd.

Answer»

Ans :- Let a and b be two odd numbers. A number is odd if 2 will not divide evenly into it. So 2 does not divide into a or b.Look then at the product ab.2 is prime, so the only way 2 could divide into the product ab is if 2 divides into either a or b. It doesn't, so ab is odd.

Look at it another way. If a and b are odd, then a and b can be written as:a=2m+1b=2n+1Where m and n are whole numbers. (Ignore negatives for the moment)Soab=(2m+1)(2n+1)=4mn+2m+2n+1=2(2mn+m+n)+1Which is odd.

oranges are bought at the rate of Rs15 per dozen and sold at the rate of Rs 20 per dozen. find the gain percent

Answer»

1 dozen = 12 pieces

So, cost price of 1 dozen of Oranges = Rs 15

So,cost price, C.P. of 1 Oranges = Rs 15 ÷ 12 = Rs 1.25

It is given that the selling price of 12 Oranges = Rs 20

So, selling price, S.P. of 1 Oranges = Rs 20÷12 = Rs 1.66

It is seen that, C.P. of 1 banana < S.P. of 1 Oranges.

∴ Profit obtained on selling 1 Oranges = S.P.—C.P. = Rs 1.66—Rs 1.25 = Re 0.41

Now,

‎‎Using Formula of Profit%

= (0.41/1.25) * 100

= 32.8%

sorry but it is wrong

answer of this question is 33.33%

s possible to have a triangle with sides3cm 5cmand 75m? explain

Answer»

According to triangle theorem, sum of any two sides of a triangle must be greater than its third side.Here 3+5= 8 which is greater than 7.Similarly 5+7=12 >3 And 3+7 = 10>5.So it is possible to have a triangle with sides 3cm, 4cm and 7cm.

according to triangle gnidg

The sum of any two sides must be greater in any triangle. here the sum of two smaller side = 3+5 = 8which is greater than longest side that is 7 cm.hence it is possible to construct such triangle...

No it is not possible to have a triangle with sides 3cm, 5cm and 7cm because the sum of all triangle is 180 and triangle all sides are equal one side is of 60 so it is not possible to have a triangle with sides 3cm, 5cm and 7cm

motheFor the preparation of cakes, baking powder is used. If at home youruses baking soda instead of baking powder, how will it affect the taste of thecake and why ?How is baking soda be converted into baking powder ?What makes the cake soft and spongy?

Answer»

(a) The advantage of using baking powder is that tartaric acid present in baking powder reacts with sodium carbonate produced during decomposition and neutralizes it. If only sodium hydrogen carbonate (baking soda) is used in making cake, then sodium carbonate formed from it by the action of heat (during baking) give a bitter taste to cake.

(b) By adding tartaric acid to baking soda we can form baking powder.

(c) Tartaric acid neutralises the sodium carbonate formed during decomposition hence, making the cake tasty and not bitter in taste.
