The length of the wire will be equal to the circumference of four semicircles that were made from it. So, if the diameter of one semicircle is 32 cm, then the radius is = 32/2 cm = 16 cm. Now, the circumference of a circle is 2*(pi)*(radius). Here we have a semi-circle, so its circumference is half of of a circle = (pi)*(radius). Then, circumference of 4 semi-circles is = 4*(pi)*(radius). The value of pi is 22/7. So, length of wire is = 4*(22/7)*16 cm = 200 cm (after rounding to the nearest hundreth).

Let x be the no. of questions I got right and y be the no. of question I got wrong. So, x+y=40........(1) & 4x-2y-21=25 4x-2y=46 2x-y=23........(2) comparing equations (1) and (2) 3x=63 x=21......(3) putting the value of equation (3) in equation (1) 21+y=40 y=19 So, 21 questions I got right

47.61 m squared. Thank you.

13.47 m Thank you.

In this case what will be the direction of displacement.

Please advice how it is east when the man is travelling west. Thank you.

Plz advise for this whether you have used displacement= final position - initial position Displacement = 1 - 0

Is it southeast direction.

The question is to prove m-n=1. I myself feel there is typo in the denominator it should 3^3m and not 3^m rest everything is okay. I tried solving i got as m-3n=3.

Hi bob you are correct but i am not able to find all the area. Can you plz plot me the graph and also the area. Thank you.

I am not able to get the answer as 3125/4√2

Please help whether the question is wrong or correct.

Thank you Bob. Can you please explain while I tried finding distance through area of triangles I did not get the same answer. With the given table I got two triangles shapes. One is 2 to 4 with 2 sec and other one is from 4 to 10 with time from 2sec to 5 sec. Rest of the shape I got is rectangles 0 to 4 with time 2 sec to 5 sec and 0 to 2 with time 0 to 2 sec. Plz share your precious time. Thank you.

Hi Bob can u plz reply

Thank you. In the book the gave answer as 75 1/2 i.e. they have obtained after subtracting 1/4 from 303/4.

Yeah I feel it should be 6ab^2

Actually my question was to find coefficient of b from 9b^3.

I need only for particular no -6 not for entire question.

Identify the terms and factors in the expression 12xyz - 6xy

Thank you

Is it 6

Thanks but I have confusion regarding this how valency is 3. We cannot use octet rule as E is unknown. As per calculation it should be 6.

Thank you. My question was to find valency for E from EO3. As per the step valency of E is 6.

My question was to find valency for E from EO3. As per the step for finding valency of E is 6. Is it correct?

That means book answer is wrong. Even I got same as 16%.

Wrong answer is this

Good

Ans is 8.6+or- 0.5
