On a 16 scale drawing of a bike, one part is 3 inches long. How long will the actual bike part be?
Arisa [49]
You would multiply 16*3 to get an estimate. 
16*3= 48
The bike would be about 48 units.
I'm assuming you mean a 16:1 scale.
16:1= 16/1 which =16 
Hope this helps!

Complete the sentence.<br><br><br> 7 is 35% of _________.
Sonbull [250]
<span>Okay, pretend the number equals X,
so x is 35%, and that would equal 7, so then 
x is still 35/100 = 7 
x = 7 which is 100/35 
x = 700/35 
x = 20 
then you get the number = 20 
I hope this was helpful, and good luck! :P</span>

The prism has a volume of 120 cm3. What would the volume of the prism be if each dimension were halved? cm3 Triangular prism wit
Citrus2011 [14]
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3
