Answer:

4186.67 cubic mm=V

Step-by-step explanation:

The volume of a sphere can be found using the equation, \frac{4}{3} \pi r^{3}. It gives us the diameter but we need the radius. To find the radius just divde the diameter by 2, so the radius of the sphere is 10mm.

\frac{4}{3} (3.14) (10^{3})=V

\frac{4}{3} (3.14) (1000)=V

\frac{4}{3}(3140)=V

4186.67 cubic mm=V

How can I express this as a single power with positive exponents?
Tamiku [17]

Answer:

5^1

Step-by-step explanation:

\sqrt{5} =5^{\frac{1}{2} } (law of indices - fractional powers)

after converting all the numbers to this form:

\frac{5^{{\frac{2}{3} }  } *  5^{\frac{1}{2} } }{5^{\frac{1}{6} } } \\

combine using law of indices:

5^(2/3+1/2-1/6) = 5^1

A sum of Rs 135 is divided into two parts. If the greater part exceeds the smaller by Rs 25,find the parts of the sum.
Alchen [17]

The parts of the sum are 55 and 80.

Step-by-step explanation:

Let,

'x' be the smaller part and

'y' be the greater part of the number.

The sum is x+y = 135.   --------(1)

The greater part y = x+25.  ---------(2)

Substitute (2) in (1),

⇒ x+(x+25) = 135

⇒ 2x+25 = 135

⇒ 2x = 110

⇒ x= 110/2

x = 55

The smaller part is 55.

Substitute x=55 in (2)

y = 55+25 = 80

The greater part is 80.
