I only know the first one well. I don't want to answer the others and maybe give false info.
Step-by-step explanation:
Egyptians were very well known to be very interested in Spirits and Gods.
Their whole dynasty was built on the dawn of their Gods. There were many, like the Greek and Roman Gods. One of the sun, one of the underworld....etc..
The pharaohs believed themselves to be god. (Due to their immense power)
Egyptians believed that after death there was an Afterlife. In that afterlife, there was games, other people (spirits), homes (graves). This might sound weird but in the graves especially of Pharaohs they placed beds, tables, chairs, games..etc..

I think it would land on the coastal section 80 times, because its a 1/3 chance it will land in any section and 1/3 x 240 = 80
The total amount of money they collected for the charity is 29.1 pounds
<h3>How to find the total amount they collected?</h3>
100 pence = 1 pounds
Hence,
52 twenty pence coins = 1040 pence = 1040 / 100 = 10.4 pounds
59 ten pence coins = 590 pence = 590 / 100 = 5.9 pounds
26 five pence coins = 130 pence = 1.3 pounds
5 fifty pence coins = 250 pence = 2.5 pounds
9 £1 coins = 9 pounds
Therefore,
The amount of money collected = 10.4 + 5.9 + 1.3 + 2.5 + 9 = 29.1 pounds

The volume of a cylinder is given by the formula <em>V</em>=π<em>r</em>²<em>h</em>². In this instance, <em>r</em> is 4 and the height is 47-12 (the height of the cone at the bottom is 12 mm and the sand goes up to 47 mm on the top portion of the hourglass, including both the cone and cylinder) or 35 mm.
<em>V</em>=π(4²)(35)=560π mm³.
The volume of a cone is given by the formula <em>V</em>=1/3π<em>r</em>²<em>h</em>². In this instance, <em>r</em> is 4 and the height is 12 mm.
<em>V</em>=1/3π(4²)(12)=π(1/3)(12)(4²)=π(4)(4²)=64π mm³.
This gives a total volume of 560π+64π=624π mm³ of sand.
Since the sand goes down to the bottom at a rate of 10π mm³/second, it will take 624π/10π=62.4 seconds for the sand to all drain out.
