stiv31 [10]

Answer:

36290 min = 604.8 hr.

Explanation:

Knowing that:

1 lbs = 453.59237 grams.

∴ 2 lbs = 907.18474 grams.

Using cross multiplication:

500 mg of iron oxide dissolved → 20 minutes.

907184.74 mg of iron oxide dissolved → ??? minutes.

∴ The time needed to dissolve 2 lbs of iron oxide = (907184.74 mg)(20 min)/(500 mg) = 36290 min = 604.8 hr.

If a block has the mass of 15.00 grams and measurements of 5.00cm by 3.00cm by 2.00cm what is the volume of the block?

Natalija [7]

Answer:

Volume = 30cm³

Explanation:

A block is a geometrical figure and its volume, -look at the figure-, follows the equation:

Volume = Width*Length*Height

As the measurements of the block are 5.00cm, 3.00cm and 2.00cm, the volume is:

Volume = 5.00cm*2.00cm*3.00cm

<h3>Volume = 30cm³</h3>

What is the sequence in the formation of the Earth and the Universe?

Bezzdna [24]

Answer:

The Earth formed billions of years after the Universe formed

Explanation:

The "universe" is said to have been formed billions of year ago through an explosion. This was called the "Big Bang Theory." This lead to the expansion of the universe owing to its high temperature and density. After which, the universe cooled down. Galaxies and stars were then formed. Some of the stars died due to explosion, which then led to the creation of planets. Such formation of the planets happened around 4.5 billion years ago. This is 9.3 billions of years later than the universe was formed (13.8 billions of years ago). So, this explains the answer.
