For 2 red beads, Yasir uses 5 yellow beads,
2+5=7 is less that the total number of beads per bracelet.
so we multiply both (2 and 5) by 2, and get (4 and 10) red beads and yellow beads.
4+10=14, so the total number is between 9 and 15 as required.
Answer:
4 red beads
10 yellow beads
The question "how much space is inside a solid?" is actually asking about the volume of that solid.
The volume of a cone is given by
where h is the height of the cone, and r is its radius.
So, you only need to plug in the values:
-v/9-5/9 I really don't know if it's fully correct, but I hope it is!
First you'd substitute x= y-3 in the first equation.
10(y-3) -10y= 1
10y - 30 -10y= 1
The y's cancel each other out, so you're left with -30= 1. That means there's no solution :)
