Math Problem

Hi I don't know how to go about this. If 3.375 = 62 inches what would 2.0625 equal in inches Thanks Gary

Re : Math Problem

What is the mean proportion of 3 and 7?

Re : Math Problem

The answer is 62 / 3.375 then multiply the result of that by 2.0625 and that's all that you need to do to get the answer

Re : Math Problem

That question doesn't make sense Hollie... we need to know how many children there are in the first place to answer that one!

Re : Math Problem

The mean proportion of 3 and 7 is √21.

A solid rectangular block of copper 5cm by 4cm by 2cm is drawn out to make a cylindrical wire of diameter 2mm. Calculate the length of wire, how do i work this out ?

Re : Math Problem

The volume of the rectangular copper block = 4*3*2 = 24 cubic centimeter.
Volume of the cylindrical wire = πr^2l (r = radius of the wire, l = length of the wire )
= 3.142*0.1^2*l
Therefore, 3.142*0.01*l = 24
Or, l = 763.84. Hence, the length of the wire is 190.96 cm.

Please help me.
I'm not sure if the answer to this question is 1/4 x^2-x^3+x^2+C

Simplify
∫x(x-1)(x-2)dx

Sorry if you can't read it well.

Re : Math Problem

Sorry i dont understand the question i think u made a mistake how many children were there?
