An aquarium measures 61 cm long, 30.5 cm wide, and 30.5 cm high.If the tank is only filled to 80% capacity with water, how much

LiRa [457]

Answer:

$V=45396.2\ cm^3$

Step-by-step explanation:

Given that,

The dimensions of an aquarium are 61 cm long, 30.5 cm wide, and 30.5 cm high.

The tank is filled to 80% capacity with water.

We need to find the water needed for this tank.

The volume of cuboid is given by :

$V=lbh$

As it is filled to 80% capacity, so,

$V=\dfrac{80}{100}\times lbh\\\\=0.8\times 61\times 30.5\times 30.5\\\\V=45396.2\ cm^3$

So, $45396.2\ cm^3$ of water is needed for this tank.

(20+80 divided by 2x8) divided [(54 divided by 9+14)divided by 4]

lesya692 [45]

Answer:

Step-by-step explanation:

Let's write out the equation:

8(20+80/2)/[(54/9+14)/4]

For the first part we get 8(100/2)

Then 50x8

Then 400

For the second part we have (6+14)/4 as we divide 54 by 9. PEMDAS

Then 20/4

Then 5

So our final answer is 400/5 which is 80.

Hope this helps!

What is the value of y? Y Y 60 O A. 120° B. 60° C. 40° O D. 30°

Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

$(y+y)+(60)=180$
$2y + 60 = 180$

Step 2: Subtract 60 from both sides.

$2y + 60 - 60 = 180 - 60$
$2y = 120$

Step 3: Divide both sides by 2.

$\frac{2y}{2}=\frac{120}{2}$
$y = 60$

Step 4: Check if solution is correct.

$(60)+(60)+60 = 180$
$120 + 60 = 180$
$180 = 180$

Therefore, the answer is B. 60°.
