Ira build a model of the great pyramid in egypt for a school project. the great pyramid has square base with sides of leght 756 ft. the legth of the great pyramid is 481 ft. ira made his model pryramid using a scale of 1 in. : 20 ft.
1. what is the leght of each side of the base of iras pryramid?
2.what is the area of the base of iras pyramid?
3.what is the height of iras pyramid?
4. ira built model using cross sections that were cut parallel to the base. what shape was each cross section?

1. The length of the base of the pyramid is 37.8 inches.

2. The area of the base is 1,428.84.

3. The height is 24.05

4. The base is a square.

Hope this helps!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
