- anonymous

let's say a human was 5 feet tall

- anonymous

but then the human was drawn with a scale factor next to it

- anonymous

and you would use the scale factor next to it to convert the measurements on the drawing to real life

- anonymous

wait but what is a scale factor? and in your own words please :)

- anonymous

it's a type of ratio

- anonymous

for example: A car drawn out had a scale factor of 1:40. For every 1 mm on the drawing, it is really 40 mm in real life

- anonymous

ok

- anonymous

anyways, next question

- anonymous

whats the complete answer with the example in it?

- anonymous

a type of ratio that can be used to convert a drawn out object's measurements on paper to the real life measurements of that object

- anonymous

that's a scale factor

- anonymous

a scale drawing is a drawing of something in real life, with measurements that are either smaller or bigger that the object/thing in real life

- anonymous

there is normally a scale factor next or in the drawing

- anonymous

and that tells you how

- anonymous

to convert the measurements in the picture to the measurements in real life

- anonymous

ok and an example of scale factor?

- anonymous

1:30

- anonymous

for every 1 cm on the paper is 30 cm in real life

- anonymous

not on the paper, but rather on the scale drawing

- anonymous

next question...

- anonymous

but can you give an example of a scale factor in words not in numbers please

- anonymous

a ratio that helps convert the measures of a scale drawing to the measures in real life

- anonymous

thats the example?

- anonymous

no, that's the definition of scale factor in my own words

- anonymous

okay, let's say there was a cow

- anonymous

oh okay :)

- anonymous

and he was drawn out 5 mm

- anonymous

on the drawing there was a scale factor of 1:20

- anonymous

so for every 1 mm in the drawing it was 20 mm in real life

- anonymous

so you would do 5*20

- anonymous

to find the measurement of the cow in real life

- anonymous

so whats the full example ?

- anonymous

what's the question, now I'm getting confused

- anonymous

the question is...
What are scale drawings? Can you give an example?

- anonymous

scale drawing-a scale drawing is a drawing of something in real life, with measurements that are either smaller or bigger that the object/thing in real life

- anonymous

example: a human was drawn 5 cm

- anonymous

every 1 cm on the drawing was really equal to 1 ft in real life

- anonymous

so the person would be 5 feet

- anonymous

so is this the full answer for the question?
A scale drawing is a ratio that helps convert the measures of a scale drawing to the measures in real life. For example, a human was drawn 5 cm. Every 1 cm on the drawing was really equal to 1 ft in real life. So the person would be 5 feet.

- anonymous

no

- anonymous

a scale factor the definition you gave me

- anonymous

I mean you gave me the definition of a scale factor

- anonymous

- anonymous

thats the definition?

- anonymous

yup

- anonymous

no, i need the definition of a scale factor not a scale drawing

- anonymous

"A scale factor is a ratio that helps convert the measures of a scale drawing to the measures in real life."

- anonymous

change drawing to factor

- anonymous

ok so is this the full answer to the question?
A scale factor is a ratio that helps convert the measures of a scale drawing to the measures in real life. For example, a human was drawn 5 cm. Every 1 cm on the drawing was really equal to 1 ft in real life. So the person would be 5 feet.

- anonymous

yes, I think that is correct

- anonymous

please make sure

- anonymous

just to be safe, I'll give you a different example

- anonymous

a cat in a drawing was 22 mm. For every 2 mm in the drawing, it would be 1 inch in real life

- anonymous

so the cat would be 11 inches in real life

- anonymous

ok

- anonymous

next question! :)

- anonymous

Can you describe the difference between complementary and supplementary angles?

- anonymous

complimentary angle: two angles with a sum of 90

- anonymous

supplementary angle: two angles with a sum of 180

- anonymous

so is this the full answer?
A complimentary angle are two angles with a sum of 90. A supplementary angle are two angles with a sum of 180.

- anonymous

yup

- anonymous

ok next!

- anonymous

okay, make it quick

3. Can you find the area and circumference of a circle given the radius or diameter?

- anonymous

yes, you can

- anonymous

how

- anonymous

area of circle:

##### 1 Attachment

- anonymous

r means radius

- anonymous

half of the diameter of a circle is what the radius is

- anonymous

##### 1 Attachment

- anonymous

that's the circumference of a circle formula

- anonymous

how do i put that in words

- anonymous

the area of a circle is pi times radius squared

- anonymous

the circumference of a circle is two times pi times radius

- anonymous

pi is typically approximated to 3.14

- anonymous

so is this the full answer...
yes, you can. The area of a circle is pi times radius squared. The circumference of a circle is two times pi times radius. Pi is typically approximated to 3.14.

- anonymous

Yes, that's correct

- anonymous

sorry I have to go to ballet now... I'll tag someone

- anonymous

@nincompoop @Astrophysics

- anonymous

nooooo! please i only have two more

- anonymous

they are quick
