Pease help!!!! Puh leeze help!!!!


The smallest spider, the PATU MARPLES of Samoa, is 0.43 millimeter long. A scale model of this spider is 8 centimeters long. What is the scale of the model? What is the scale FACTOR of the model?

Answer 1

The scale is how many times an object or place (as in a map) has been made larger or smaller. You are comparing millimeters and centimeters, so the first step is to convert one of the numbers to the same unit as the other.
8 cm = ____ mm?
Then divide one length by the other (both in millimeters) to get the scale.

Answer 2

80?

Answer 3

8 cm 10 mm/cm => 8*10 mm = 80 mm
Yes. :)

Answer 4

right

Answer 5

Now the next step is to divide

Answer 6

80 divide by 10?

Answer 7

The model size is 80 mm, the real size is 0.43 mm. Those are the numbers you need to divde.

Answer 8

18.6?

Answer 9

186

Answer 10

as in one hundred eighty six?

Answer 11

yes

Answer 12

Now that you divided, the scale is 186:1 (that meanse the model is 186 times bigger than the real spider), and the scale factor is 186

Answer 13

oh yeah i got tht thanks so uch for you help! wait so 186 is the scale or is it the scale factor?

Answer 14

o thx u vry much

Answer 15

wait... is it 186 mm?

Answer 16

No, it's simply 186. It just means that the object was made 186 times larger to become the model. Since you divided 80 mm by 0.43 mm, or (80 mm)/(0.43 mm), the mm units cancel out. The scale factor has no units.
