The scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.

<h3>What is the scale factor from rectangle Q to rectangle R?</h3>

In geometry, the scale factor is a ratio of the resulting length to the initial length. Since the area of the square is equal to the square of its side length, then the scale factor is equal to:

k² = A' / A

k = √(A' / A)

Where:

  • k - Scale factor
  • A' - Area of the rectangle R.
  • A - Area of the rectangle Q.

If we know that A = 2 and A' = 72, then the scale factor is:

k = √(72 / 2)

k = √36

k = 6

Then, the scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.

The number of chairs on a ski lift is inversely proportional to the distance between them a lift has 70 chairs when there’s spac
zhannawk [14.2K]

Answer:

Space between 80 evenly spaced chairs = 21m

Step-by-step explanation:

So, according to the given statement, we have the following expression:

No. of chairs ∝ \frac{1}{Distance.Between.chairs}

70 chairs are 24m apart, so it can be written as:

70  ∝ \frac{1}{24}

For, 1 chair , we divide both sides by 70

\frac{70}{70} ∝ \frac{1}{24(70)}

1 ∝ \frac{1}{24 (70)}               -----------------------(Equation 1)

<u>For 80 chairs:</u>

Multiply both sides of <em>Equation.1</em> by 80

80  ∝ \frac{80}{24 (70)}      

80  ∝ \frac{1}{21}      

So according to the above relation,

<em>80 evenly spaced chairs will have a space of </em><em>21 m</em><em> between them.</em>

Tre Algebra<br>Assignment Day 4<br>Solve each equation<br>1) -2-4-2<br>-2<br>.1​
Debora [2.8K]

Answer:

If your question is -2 - 4 - 2 - 2.1 then the answer is -10.1

Step-by-step explanation:

-2 - 4 - 2 - 2.1

= (-2 - 4 ) - 2 - 2.1                Combine -2 with -4 or subtract them

=  -6 - 2 - 2.1                        

= (-6 - 2 )- 2.1                       Combine -6 and -2

= -8 -2.1                                Combine -8 and -2.1

= -10.1
