You cannot half 31 nor 33 anymore so it's in its simplest form. It can no longer divide to make it a lower number.

31/33 is in simplest form because both 31 and 33 do not have a common factor that be used to simplify.

14.12 = 1/2 (3.6x - 12.8)<br><br> show work

Sergio039 [100]

Answer:

x = 11.4

Step-by-step explanation:

14.12 = $\frac{1}{2}$ ( 3.6x - 12.8 )

Rewrite so that the equation is entirely in decimals;

14.12 = 0.5( 3.6x - 12.8 )

Distribute;

14.12 = 1.8x - 6.4

Inverse operations;

14.12 = 1.8x - 6.4

+6.4 +6.4

20.52 = 1.8x

/1.8 /1.8

11.4 = x

Answer:

$difference\hspace{0.2cm} between\hspace{0.2cm} the\hspace{0.2cm} two\hspace{0.2cm} areas\hspace{0.2cm} =\hspace{0.2cm} 9(2\sqrt{3} -\pi)$

Step-by-step explanation:

i) area of circle = $\pi \times r^{2} = 9\pi \hspace{0.1cm} where \hspace{0.1cm}r = 3.$

ii) therefore side of hexagon, $a = 2\sqrt{3}$

iii) therefore area of hexagon, $A = \frac{3\sqrt{3} }{2} a^{2} = \frac{3\sqrt{3} }{2} \times 12 = 18\sqrt{3}$

iv) difference between the two areas in iii) and i) $=9(2\sqrt{3} -\pi)$

describe a real-world situation that can be modeled by the equation y=1/20x. Be sure to describe what each variable represents.

MissTica

Y = 1/20x

In this equation, y is equal to one twentieth times x. Using PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction) from left to right, we would first divide 1 by 20 and then multiply it by x. An example of a real world problem is this:

Georgia is throwing a party for her friends. She has a large cake to split among all of the party guests. She has cut the cake into 20 slices for each of the friends who show up. She wants to know how much cake she will give in total to all of her friends.

In this equation, y is equal to the total amount of cake that will be eaten by Georgia's friends at the party. Because the cake is sliced into 20 pieces, each friend will receive 1/20 of the cake. X is equal to the number of friends who show up to the party.
