Robin is making a bead necklace .she wants to use 717 beads to make 57 necklaces. of she wants each necklace to have the same number of beads, how many beads will she have left over

First off, I divided 717 and 57. I got the number 12.578...

I then rounded the number down to a whole number and multiplied that by 57. I got 684 beads.

That should be how much beads you use, so subtract the total amount of beads you have and the total amount of beads you'll use.

717- 684 is 33. That should be your answer :)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

no idea
