9. Observing the pattern, the decimal digit at position n is 9 when n is even and 0 when n is odd. Because 44 is an even number, the 44th digit after the decimal point is 9.
The diagonal that crosses the interior of the cube is the longest segment. The hypotenuse corresponds to the longest side in a right triangle. In this case, the cube's diagonal serves as the hypotenuse of a right triangle, with the legs being the diagonal of one of its faces and one of its edges. The edges are the shortest sections and function as the legs of a right triangle where the face's diagonal acts as the hypotenuse.
He created a scalene triangle.
A scalene triangle has sides and angles that do not measure alike.
Customers served in 0.5 hours : 3.6 versus x customers served in 7.5 hours
-------------------- = --------------------
0.5 hours 7.5 hours
Applying cross multiplication:
3.6 multiplied by 7.5 equals x times 0.5
Dividing both sides by 0.5:
x = (3.6 * 7.5) / 0.5
x = 54
So, you assisted 54 customers in 7.5 hours.
