The Great Pyramid of Giza was constructed as a regular pyramid with a square base. It was built with an approximate volume of 2592276 cubic meters and a height of 146.5 meters. What was the length of one side of its base, to the nearest meter?

Answers

Answer 1

Answer: volume of a square-based pyramid = base edge^2 * height/3
so:
2,592,276 = base edge^2 * 146.5/3; therefore the base edge is approximately 230.4m

Answer: 1/2

(y-3)=-2(x-4)
(y-3)= -2x+8
y= -2x+11
perpendicular slopes are always reciprocals and opposite so the slope would be
slope=1/2

Two times the sum of nine and a number is the opposite of 9.
Write an equation and solve.

Answers

The number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Two times the sum of nine and a number is the opposite of 9.

Let the number be x:

2(x + 9) = -9

2x + 18 = -9

2x = - 9 - 18

2x =- 27

x = -27/2

Thus, the number is -27/2 if two times the sum of nine and a number is the opposite of 9 after applying the concept of the linear equation.

Which of these is a simplified form of the equation 7p 4 = − p 9 2p 3p? 13p = 13 3p = 5 7 = 4 11 = 15

Answers

Answer:

$\boxed{\sf{3p=5}}$

Step-by-step explanation:

To find:

The value of p

Given:

7p + 4 = −p + 9 + 2p + 3p

$\sf{7p+4=-p+9+2p+3p}$

Isolate the term of p, from one side of the equation.

Combine like terms.

$\rightarrow \sf{7p+4=-p+2p+3p+9}$

Add the numbers from left to right.

-p+2p+3p=4p

7p+4=4p+9

Then, you subtract by 4 from both sides.

$\sf{7p+4-4=4p+9-4}$

Solve.

7p=4p+5

Subtract by 4p from both sides.

7p-4p=4p+5-4p

Solve.

$\boxed{\sf{3p=5}}$

Divide by 3 from both sides.

3p/3=5/3

Solve.

p=5/3

Divide is another option.

5/3=1.6666

So, the final answer is 3p=5.

I hope this helps, let me know if you have any questions.
