Given:
Point B is the center of the base.
Each side of the base = 10 cm
To find:
The height of the pyramid.
Solution:
It is given that the measure of each side of the base is 10 cm. It means the base is square. The length of the diagonal of a square is:
Where, a is the side length of the square.
Putting in the above formula, we get
It is given that point B is the center of the base. It means point B bisect each diagonal of a base. So,
In a right angle triangle,
In triangle ABC,
Round the value to the nearest integer.
The height of the pyramid is about 7 cm. Therefore, the correct option is A.
The large tire makes 3 rotations, and the small tire makes 11 rotations.
We must find the circumference of each tire to know how many feet are covered when it makes one complete rotation.
C=πd
For the large tire, this means:
C=3.14(60) = 188.4
Dividing 600/188.4, we get (to the nearest whole number) 3 rotations.
For the small tire, we have:
C= 3.14(2*9) = 3.14(18) = 56.52
Dividing 600/56.52, we get (to the nearest whole number) 11 rotations.

Step-by-step explanation:
Answer:
7x = 9
Step-by-step explanation:
3x -2y = 15
4x+2y = -6
---------------------
7x + 0y = 9
7x = 9
