A necklace is being made with beads that are each 1.25 centimeters in diameter. How many beads does it take to make a necklace that is 30 centimeters long

$3.60 will be spent on the necklace.

Step-by-step explanation:

to solve this problem we have to divide the length of the necklace (30cm ) by the diameter of each bead (1.25) to obtain the number of beads needed for the necklace.

So, mathematically speaking:

30 cm / 1.25 cm =24 beads

Now, we have to multiply the number of beads by the cost of each one ($0.15).

24 x 0.15=  $3.60

S000, $3.60 will be spent on the necklace.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
