Answer:240
Step-by-step explanation:
40 pencils in one minute
2 hours=120 minutes
40*120=480
480/2=240 boxes
Since they are similar, that means they are proportionally the same.
So KL is similar to PN
JL is similar to PM
So,
You need to find how much bigger is the second triangle from first.
It is proportionally scaled up.
KL/JL = PN/ PM
You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)
5/6 = PN / 9
Cross-multiply
PN * 6 = 5*9
6PN = 45
PN =45/6
PN =7.5
First the distributive property actually means "to share"
Second here's how you do it ...
the two numerators are multiplied , same with the denominator
4 x 10 and 25 x 1
this gets you 40/25 as an improper fraction but here is the simplified answer
1 3/5
