Jamie wants to know the volume of his gold ring in cubic centimeters. He gets a rectangular glass with a base

mixer [17]

Answer:

1.50 cm^3.

Step-by-step explanation:

The ring will displace its own volume of water.

The increase in height of the water = 4.25 - 4 = 0.25 cm.

Therefore the increase in the volume = area of the base of the glass * 0.25

= 3 * 2 * 0.25

= 6 * 0.25

= 1.50 cm^3.

This is also the volume of the ring.

Is 8/5 proportional to 24/15 ?

DiKsa [7]

Hey there!

The answer to your question is, yes, it is

Given:

$\frac{8}{5}$ $and$ $\frac{24}{15}$

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

$8*15=24*5$

Let's solve it and see if it is true:

$8*15=24*5$

$120=120$

Therefore, they are proportional.

Cross products

WORD DEFINITION:

Given two fractions, you can take the numerator of the first fraction multiplied by the denominator of the second fraction and it should equal the denominator of the first fraction multiplied by the numerator of the second fraction.

ALGEBRAIC DEFINITION:

Given two fractions, $\frac{a}{b}$ $and$ $\frac{c}{d}$ , $a*d$ should equal to $b*c$
