Explain how an enlargement or a reduction in the dimensions of a building would cause a change in the scale factor.

2 answers:

8 0

The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship.

Answer:

It would create an enlarged figure.

Explanation:

A scale factor of

results in a figure of equal dimensions or an isometric figure.

A scale factor of less than

results in a figure of reduced dimensions .

A scale factor of greater than

would result in a figure of enlarged dimensions.

, it would create an enlarged figure.

Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

The size of a cell is typically found by capturing an image under a microscope then using software to measure its diameter. Two

Answer:

7.789×10^-2 = 0.07789 cm

Step-by-step explanation:

Your calculator can find the difference of the two given diameters and express it in any format you like.

The attached image of a calculator display shows the difference of the cell diameters is 0.07789 = 7.789×10^-2 cm.

The difference of two numbers with different exponents is found by first adjusting the exponents so they are the same. Here, we choose to adjust both numbers so they have the highest exponent value.

8.83×10^-2 - 6.01×10^-3

= 8.39×10^-2 - 0.601×10^-2 = (8.39 -0.601)×10^-2 = 7.789×10^-2

Alternatively, you can convert both numbers to standard form and do the subtraction that way.

8.83×10^-2 - 6.01×10^-3

= 0.0883 -0.00601 = 0.07789

<em>Additional comment</em>

The second attachment shows the relationship between place values and their multiplier in scientific notation.

The choice of exponent when computing the sum or difference of numbers in scientific notation is usefully informed by an estimate of the value of the sum or difference. A proper choice can avoid the need to adjust the exponent of the result of the operation. Here, we see the subtraction will change the larger value by less than 10%, so the exponent of the result in scientific notation will be that of the larger value (-2).
