Answer:
Step-by-step explanation:
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.
4 : 5 ( = 9 too little )
8 : 10 ( = 18 just right)
12 : 15 ( = 27 too much)
So per necklace, 8 yellow beads and 10 blue beads would be needed.
I hope this helps :-)
C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.
You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer
