Mathematics

Answer:

Step-by-step explanation:

Density of copper = 9.86 g / cm^3 = 9860 kg / m^3

= 9.86 x 1 / 1000 kg / cm^3 = 9.86 / 1000 Kg / cm^3

= 0.00986 kg / cm^3

= 9.86 x 1 / 1000 kg (1 / 100 m)^3

= 9.86 x 1000000 / 1000 kg / cm^3

Mass "m" = 9860 kg / m^3

thus the mass of copper in solid form is m =  9860 kg / m^3

Help me please i need this urgent

In pythagoras's theorem, generally a is the shortest side, b is the second shortest and c is the hypotenuse: a^{2} +  b^{2} = c^{2}. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.

Answer:

around 13.18

Step-by-step explanation:

the middle square is 2*2 = 4

the triangle then is 2^2 + 6^2 = 40  -> sqrt40 = 6.325

and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828

4+6.325+2.828 = 13.18
