You find a ring with a mass of 107 g. You fill a graduated cylinder up with 10 ml of water and put the ring into the cylinder. The water rises up to the 15 ml mark. What is the ring made of?

Platinum

Step-by-step explanation:

If the water rises by 5 mL then that is the volume of the ring, using this and the mass (107g) we can find the density of the metal using

Density = Mass/Volume

Density = 107g/5mL

Density = 21.4 g/mL

If we look at a density chart on google we can find that the metal with a density of 21.4 g/mL is platinum

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
