You round it by checking the Hundreths and if thr hundreths is larger than 4 its posible to round it ( the tenths)

remember
(x^m)/(x^n)=x^(m-n)
and
(x^m)^n=x^(mn)
and
(xyz)^m=(x^m)(y^m)(z^m)
and
(m/n)^a=(m^a)/(n^a)
and
x^-n=1/(x^n)

so
$( \frac{6mn^{-2}}{3m^{-1}n^2} )^{-3}$ =
$( \frac{6}{3} )^{-3}( \frac{m}{m^{-1}} )^{-3}( \frac{n^{-2}}{n^2} )^{-3}$ =
$(2^{-3})((m^2)^{-3})((n^{-4})^{-3})$ =
$( \frac{1}{2^3})(m^{-6})(n^{12})$ =
$( \frac{1}{8} )( \frac{1}{m^6})(n^{12})$ =
$\frac{n^{12}}{8m^6}$

What is the volume of the cylinder?

Anna007 [38]

Answer:

B. 2010.62 ft³

Step-by-step explanation:

The formula for the volume of a cylinder is ...

V = πr²h . . . . . where r is the radius and h is the height

Filling in the numbers and doing the arithmetic, we get ...

V = π(8 ft)²(10 ft) = 640π ft³ ≈ 2010.6193 ft³ ≈ 2010.62 ft³

The volume of the cylinder is about 2010.62 ft³.

a pool is leaking water at a constant rate. The amount of water in the pool changes by -1 1/4 every hour. what is the total chan

malfutka [58]

The total change in the water in the pool after 2 1/2 hours given the rate of leakage is -3 1/8,

<h3>What are fractions?</h3>

A fraction is a non-integer. It is made up of numerators and denominators. A mixed fraction is made up of a whole number and a proper fraction. An example is 2 1/2.

<h3>What is the total change in the water?</h3>

The total change in the water = -1 1/4 x 2 1/2

= -5/4 x 5/2 = -25/8 = -3 1/8

Which pair of numbers is relatively prime?

Evgen [1.6K]

Answer:

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Step-by-step Explanation:

<u>Answer - A</u>

<u />

Two numbers are relatively prime if they have no common factors (aside from 1). So lets solve for the factors of the number to see if they are relatively prime...

A. Relatively Prime

26=1,2,13,26

99=1,3,9,11,33,99

B. NOT RELATIVELY PRIME

90=1,2,3,5,6,9,10,15,18,30,45,90

117=1,3,9,13,39,117

C. NOT RELATIVELY PRIME

100=1,2,4,5,10,20,25,50,100

202=1,2,101,202

D. NOT RELATIVELY PRIME

201=1,3,67,201

444=1,2,3,4,6,12,37,74,111,148,222,444
