Answer:
c. 63 toothpicks
Step-by-step explanation:
ok so the base for 16 would be 16 toothpicks
when i first see it that no matter what we would be multiplying 16 by 3 for that triangle shape
16 x 3 = 48
then we would have 15 for the connection toothpicks
48 + 15 = 63
16 would have 63 toothpicks
369
Step-by-step explanation:
Arc length=(π*diameter)*(angle/360°)
88π=π*diameter*80°/360°
diameter=369
Answer: n=3
Step-by-step explanation:
Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.
Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:
5/4(4n+4)=7n-1. Now distribute:
5n+5=7n-1. Now simplify:
6=2n. Now simplify again:
n=3
Hope this helps you with your big ideas math hw!
