You start with the initial amount of rain (-11) and then work through the problem. The first part has you adding 1/2 seven times so you end up with -11 + 1/2(7) = -7.5. However it then drops 2 1/4 for three months so you do -7.5 - 2 1/4(3) = -14 1/4

In a naval engagement, one-third of the fleet was captured, one-sixth was sunk, and two ships were destroyed by fire. One-sevent

Otrada [13]

Answer:

60 ships.

Step-by-step explanation:

Let the total number of ships in the naval fleet be represented by x

One-third of the fleet was captured = 1/3x

One-sixth was sunk = 1/6x

Two ships were destroyed by fire = 2

Let surviving ships be represented by y

One-seventh of the surviving ships were lost in a storm after the battle = 1/7y

Finally, the twenty-four remaining ships sailed home

The 24 remaining ships that sailed home =

y - 1/7y = 6/7y of the surviving fleet sailed home.

Hence

24 = 6/7y

24 = 6y/7

24 × 7/ 6

y = 168/6

y = 28

Therefore, total number of ships that survived is 28.

Surviving ships lost in the storm = 1/7y = 1/7 × 28 = 4

Total number of ships in the fleet(x) =

x = 1/3x + 1/6x + 2 + 28

Collect like terms

x - (1/3x + 1/6x) = 30

x - (1/2x) = 30

1/2x = 30

x = 30 ÷ 1/2

x = 30 × 2

x = 60

Therefore, ships that were in the fleet before the engagement were 60 ships.

For a Chinese New Year celebration, James and Zhou are making a dragon costume similar to the one shown above.

Lilit [14]

Answer:

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

Let the length of fabric in meters still required be = $x$

The total length can be given as :

⇒ $(15+17.6+x)\ m$

⇒ $(32.6+x)\ m$

The total fabric required = 56.6 m

So, the equation to find $x$ will be:

$32.6+x=56.6$

Subtracting both sides by 32.6

$32.6+x-32.6=56.6-32.6$

∴ $x=24$

Thus, 24 meters of fabric is still required to make the costume.
