The largest of the Great Pyramids in Egypt was built with a square base, having edges that measured 754 feet and a height of 418
12345 [234]

Answer:

79,213,229 ft3

Step-by-step explanation:

The volume of a pyramid is given by the following formula:

Volume = (1/3) * B * h

Where B is the base area and h is the height.

The side of the base is 754 feet, so the base area is:

B = 754^2 = 568516 ft2

Then, the volume of the pyramid is:

Volume = (1/3) * 568516 * 418 = 79213229.33 ft3

Rounding to the nearest cubic foot, we have:

Volume = 79,213,229 ft3

sammy [17]

Answer:

One atmosphere is also the pressure caused by the weight of a column of fresh water of approximately 10.3 m. A diver 25 m underwater experiences a pressure of about 3.5 atmospheres (1 atm of air plus 2.5 atm of water). The added pressure on tom's chest from the water would make inhaling low pressure air from the surface extremely difficult.

You have invested $12,000 into two different companies company 1 earns you 6% on your investment each year and Company 2 earns y
vovikov84 [41]

The correct questions says 5% each year for Company 2.

The amount invested in companies A and B are; $10,000 and $2000 respectively.

<h3>Percentages on Investment</h3>

Let the amount in Company 1 be; x

Let the amount in Company 2 be; y

Hence, we have the equation;

  • x + y = 12,000

Additionally, 6% is earned on company 1 and 50% on company 2.

Therefore, we have;

  • 0.06x + 0.05y = 700

  • 6x + 5y = 70000

by solving the equation simultaneously;

  • 6(12000 -y) + 5y = 70000

  • 72000 - 6y + 5y = 70000

  • y = $2000

  • x = $12000 - $2000

  • x = 10000

  • x = $10,000
