If the scale factor between a scale drawing of a rectangle and the real object is 1:3 what would be the ratio of the areas?

Answer:

The ratio of the areas will be will be 1 : 9

Step-by-step explanation:

The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.

The linear scale factor is quite different from the area scale factor but related to it in the following way:

The area factor can be obtained by squaring the linear scale factor.

This is Area factor = (Linear scale factor) ^2.

Linear scale factor = (1:3)

Area factor = 1^2 : 3^2

Area factor will be 1: 9

Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9

Answer:

  • $22.12
  • $24.51

Step-by-step explanation:

For some growth factor f each year, the growth factor over 20 years is given as ...

  f^20 = 1 +0.51 = 1.51

Then the growth factor in 10 years is ...

  f^10 = (f^20)^(1/2) = √1.51 ≈ 1.22882

__

a) In the 10 years between 1998 and 2008, the price of a basic haircut would rise to ...

  $18 × 1.22882 ≈ $22.12 . . . price in 2008

__

b) In the 10 years between 2003 and 2013, the price of a basic haircut would rise to ...

  $19.95 × 1.22882 ≈ $24.51 . . . price in 2013

Which statement correctly describes the graph of y = x + 7?
Stolb23 [73]

Answer:

see the explanation

The graph in the attached figure

Step-by-step explanation:

we have

y=x+7

This is the equation of a line in slope intercept form

y=mx+b

m=1\\b=7

therefore

The slope is positive

The y-intercept is the point (0,7)--->  (value of x when the value of y is equal to zero)

The x-intercept is the point (-7,0) --->  (value of y when the value of x is equal to zero)

To graph the line plot the intercepts and join the points

see the attached figure
