Aleksandr [31]

Candice's bracelet is made from silver because the volume of her bracelet is; 1.72cm³

<h3>Density, Mass and Volume</h3>

By definition, the density of an object is the ratio of its mass per unit volume.

  • Density = Mass/Volume.

Hence, for silver;

  • 10.49 = 18/Volume.

  • Volume = 18/10.49

Volume = 1.72cm³.

What is the Gcf of the number below
never [62]

9514 1404 393

Answer:

  b.  60

Step-by-step explanation:

The list of factors is 2, 3, 5, 7. The list of common factors is 2, 3, 5. The lowest exponents on those factor are ...

  2^2 × 3^1 × 5^1 = 60

The GCF of 720 and 2100 is 60.

_____

<em>Additional comment</em>

You can verify this using Euclid's method of finding the GCF.

  2100/720 = 2 r 660

  720/660 = 1 r 60

  660/60 = 11 r 0 . . . . 60 is the GCF

Find the remainder from the division. If it is zero, the divisor is the GCF. If it is non-zero, replace the largest number with the remainder, and repeat.
