Answer:

The volume of the fish tank is 48000 cubic centi meter.

Step-by-step explanation:

The volume of a Cuboid is l*b*h (length*breadth*height)

Here,

length(l) =60 cm

breadth(b)= 20 cm

height(h)=40 cm

Volume=l*b*h

Volume= 60cm*20cm*40cm

Volume= 48000 cubic centimeter

Answer:

48000 cm³

Step-by-step explanation:

In this question we are asked to find the volume of the fish tank with a length of 60 cm, width of 20 cm and a height of 40 cm. We need to utilise the formula to work out the volume of this fish tank. We can see that the fish tank is in a cuboid shape so we use the cuboid volume formula which is :

→ Cuboid volume = Length × Width × Height

⇒ Substitute in the values

→ Cuboid volume = 60 × 20 × 40

⇒ Simplify

→ Cuboid volume = 48000

The volume of a cuboid with a length of 60 cm, width of 20 cm and a height of 40 cm is 48000 cm³

Answer:

$v=\sqrt{\frac{E}{m}}$

Step-by-step explanation:

The formula is given as:

$E=mv^2$

We need to solve this formula for v, that means that v to one side and let it be solved in terms of the other variables (E and m). First, we isolate v:

$E=mv^2\\\frac{E}{m}=\frac{mv^2}{m}\\\frac{E}{m}=v^2$

To isolate v, and eliminate the "square", we need to take square roots of both sides, that will give us v in terms of the other variables:

$\frac{E}{m}=v^2\\\sqrt{\frac{E}{m}}=\sqrt{v^2}\\\sqrt{\frac{E}{m}}=v$

Putting v to left side (convention), we finally have:

$v=\sqrt{\frac{E}{m}}$

Lucy's fish tank has 14 liters of water in it. She plans to add 5 liters per minute until the tank has at least 49 liters. What

Vikentia [17]

Answer:

14 + 5t > = 49 (thats a greater then or equal sign)

5t > = 49 - 14

5t > = 35

t > = 35/5

Find the missing angle measures in the triangles

Svetllana [295]

For the first triangle, I believe the given angles are 85 and 53. If I am incorrect, please let me know and I'll resolve it.

The answer for 1 would be 42.

2nd triangle- 69 is the missing angle measurement.

3rd- 64 degrees.

4th- 53

The reasoning behind all of these: The total of all three interior angles should be 180 degrees. So when you add the two GIVEN angles, and subtract that from 180, this answer is your missing angle.
