The pyramids at Giza include several square-based pyramids that were built in honor of the Egyptian gods. One of these incredibl

e monuments is the Khafre pyramid, built as part of a temple complex, with the famous Sphinx at its base. The base length of this pyramid is seven hundred five feet, and its height is four hundred seventy-one feet. Massive dimensions indeed! Calculate the volume of the Khafre pyramid. Show the steps of your solution and explain your work.

First step: write the equation for the volume of a pyramid V=(LWH)/3
Second: provide the variables V=(700*700*471)/3
Third: Solve V=7.69 * 10^7 or 76,900,000 feet cubed

What is the greatest common factor of 44c^5, 22c^3 and 11c^4
Alexxandr [17]

\text{ GCF of } 44c^5, 22c^3 , 11c^4 \text{ is } 11c^3

<em><u>Solution:</u></em>

Given that, we have to find the greatest common factor of 44c^5, 22c^3 , 11c^4

The greatest number that is a factor of two (or more) other numbers.

When we find all the factors of two or more numbers, and some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor

\underline{\text{ GCF of } 44c^5, 22c^3 , 11c^4 :}

First find the GCF of numbers and then find the GCF of variables and then multiply them together

<em><u>Step 1: GCF of 44, 22 and 11</u></em>

The factors of 11 are: 1, 11

The factors of 22 are: 1, 2, 11, 22

The factors of 44 are: 1, 2, 4, 11, 22, 44

11 is the greatest factor that is common in above three list

Then the greatest common factor is 11

\text{ Step 2: GCF of }c^5, c^3 , c^4

c^5 = c^3 \times c^2\\\\c^3 = c^2 \times c^1 \text{ or } c^3\\\\c^4 = c^3 \times c^1

Thus the greatest common factor is c^3

Step 3: Multiply the GCF of 44, 22, 11 and GCF of c^5, c^3 , c^4

\text{ GCF of } 44c^5, 22c^3 , 11c^4 = 11 \times c^3 = 11c^3

Thus \text{ GCF of } 44c^5, 22c^3 , 11c^4 \text{ is } 11c^3

Hello there &gt;3 i would like explanation for this :)
Blizzard [7]

Answer:

  75

Step-by-step explanation:

Let t and u represent the tens and units digits, respectively.

  t = u + 2 . . . . the tens digit exceeds the units digit by 2

  t + 2u = 17 . . . . the sum of the tens digit and twice the units digit is 17

Substituting for t in the second equation, we get ...

  (u +2) +2u = 17

  3u = 15 . . . . . . . . subtract 2

  u = 5 . . . . . . . . . . divide by 3

  t = u+2 = 7

The number is 75.

_____

<em>Check</em>

7 exceeds 5 by 2. 7 + twice 5 = 7 + 10 = 17.

Why does a horizontal line have a slope of 0, but a vertical line has anundened slope?
aleksley [76]
<span>The slope of a line is defined as the rate of change on the vertical axis, divided by the rate of change on the horizontal axis, Δy/Δx. So for a horizontal line, the rate of change on the y axis is zero, this means that it's slope will be 0/Δx and for vertical line, x-axis does not change, which make the denominator 0 Δy/0.</span>

Jason has 60 cars. 30% is blue. How many are blue?
Dmitriy789 [7]
So to figure out 10% of this would be to remove the 0. that would be six. since 30÷10 is 3, we have to do 6×3. that would be 18, so 30% of 60 is 18

A system of equations and its solution are given below. System A Complete the sentences to explain what steps were followed to o
sergiy2304 [10]

Answer:

To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.

Step-by-step explanation:

A system of equations and it’s solution are given below.

System A.

x-y=3

-2x+4y=-2

Solution: (5,2)

Complete the sentences to explain what steps were followed to option the system of equations below.

System B

x-y=3

2x=10

To get to system B the (first/second) equation in system A was replaced by the sum of that equation and the (first/second) equation multiplied by (4....2.....-3) . The solution to system B (is/ is not) the same as the solution to system A.

Solution:

To get system B:

First write the first equation in system A. x - y = 3

Multiply the second equation in system A by 4 and add to the first equation in system A to get:

2x = 10

x = 10/2 = 5

Put x = 5 in x - y = 3

5 - y = 3

y = 5 - 3 =2

The solution to system B is the sam as that of system A

To get to system B the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 4. The solution to system B is the same as the solution to system A.
