Destiny designs necklaces. She uses between 15 and 20 yellow and blue beads in a ratio of 4 yellow beads to 5 blue beads.. how many should she use

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

i agree because i see the other persons thinking is clear

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
