<em>Answer:</em>

<em>The answer is :  </em><em><u>" 1/8 "</u></em><em> . </em>

<em>Step-by-step explanation:</em>

<em>(6 * 3⁻¹) ⁻³ =  (6 / 3¹) ⁻³ = 2⁻³ = 1 / 2³ = </em><u><em>1/8</em></u><em> ; which is answer </em>

<em> </em>

<em><u>Note that n⁰</u></em><em> = 1 ;  regardless  of what "n" is equal to;  </em>

<em>                          and any value, multiplied by "1", equals that same value. </em>

<em> </em>

<em>so "n⁰ " ; which equals "1" ; is simply "canceled out" . </em>

The answer is 2. Here's why:

First if all, anything to the power of 0 is 1.
So n^0=1.
You need to plug in 3 for m, so then 6(3)^-1.
3^-1=1/3.
6 × 1/3= 6/3=2
2×1=2.

Justify each step of the solution by stating the property that was used to get to each step.
trapecia [35]

For this case we have the following expression:

4.5 (8-x) + 36 = 102-2.5 (3x + 24)

Applying distributive property to the terms within parentheses we have:

36-4.5x + 36 = 102-7.5x-60

We add similar terms on both sides of equality considering that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

72-4.5x = 42-7.5x

We add 7.5x to both sides of equality:

72 + 3x = 42

We subtract 72 from both sides of equality:

3x = -30

We divide between 3 on both sides of equality

x = -10

ANswer:

Drag a statement or reason to each box to complete this proof.
alukav5142 [94]

The table to complete the proof is as follows

Equation                                                              statement

1. m∠ABD = 60°, m∠DBC=40°                               Given

2. m∠ABD + m∠DBC = m∠ABC               Angle Addition Postulate

3. 60° +  40° = m∠ABC                           Substitution Property of Equality

4. 100° = m∠ABC                                                  Simplifying

5. ∠ABC is an obtuse angle.                       greater than 90 degrees

6. △ABC is an obtuse triangle.                Definition of obtuse triangle

<h3>What is obtuse angles?</h3>

When an angel is greater than 90 degrees the angle is said to be an obtuse angle.

For the question solved here m∠ABC is greater than 90 degrees hence an obtuse angle.

Andrea has 3 tiles. One is a regular octagon, one is a regular pentagon and one is a regular hexagon. Andrea thinks the 3 tiles
HACTEHA [7]

From calculations, we can say that the given tiles will not fit together perfectly.

<h3>How to find the sum of interior angles of a Polygon?</h3>

If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.

Expression for the measure of the interior angle of a polygon,

Interior angle of a polygon = [(n - 2) * 180]/n

Interior angle of a pentagon = [(5 - 2) * 180]/5 = 108°

Interior angle of a hexagon = [(6 - 2) * 180]/6 = 120°

Interior angle of an octagon = [(8 - 2) * 180]/8 = 135°

To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°

Sum of all interior angles = 108° + 120° + 135° = 363°

Therefore, given tiles will not fit together perfectly.
