Answer:

The volume of the ring is 12.6 $cm^{3}$

Step-by-step explanation:

The volume of the ring will be equal to the increase in the volume after the ring is dropped. In order to find by how much volume increased we just subtract the volume before the ring was dropped from the volume that was recorded after the ring was dropped, and so we get...

(9.2 x 7 x 4.5) - (8.8 x 7 x 4.5) = 289.8 - 277.2 = 12.6 $cm^{3}$

Brian scored 92, 87 and 88 on three science tests. Write and solve an equation to find the score Brian will need on the fourth s

Marta_Voda [28]

Answer:

You would need to score a 93% to have an average of 90.

Step-by-step explanation:

Well, to check my work you would need to find the average.

So, 93 + 92 + 88 + 87 = 360. Then you divide by four; 360 / 4 = 90. ^^

Half a number plus 5 is 11.What is the number?

SOVA2 [1]

<h3>Solution :</h3>

<u>Let x be the number</u>

$\small\bold\red{→}\small\bold{(\frac{1}{2} )x + 5 = 11}$

$\small\bold\red{→}\small\bold{(\frac{1}{2})x + 5 - 5 = 11 - 5}$

$\small\bold\red{→}\small\bold{(\frac{1}{2})x = 6}$

$\small\bold\red{→}\small\bold{2 × (\frac{1}{2})x = 6 × 2 }$

$\small\bold\red{→}\small\bold{x = 12}$
