Answer:
Rosa is correct
Step-by-step explanation:
Rosa has array (6 rows and 8 columns). She can break this array into two smaller arrays in such ways:
- 1st array
(5 rows and 8 columns) and 2nd array
(1 row and 8 columns);
- 1st array
(4 rows and 8 columns) and 2nd array
(2 rows and 8 columns);
- 1st array
(3 rows and 8 columns) and 2nd array
- 1st array
(6 rows and 1 column) and 2nd array
(6 rows and 7 columns);
- 1st array
(6 rows and 2 columns) and 2nd array
(6 rows and 6 columns);
- 1st array
(6 rows and 3 columns) and 2nd array
(6 rows and 5 columns);
- 1st array
(6 rows and 4 columns) and 2nd array
So, there are even more than 3 different ways.
Hello,
Let C the center of wheel.
P is the Carl's seat
A is the intercept of the horizontal line passing by A and the vertical line passing by P
In the right triangle PAC, sin 72°=AP/CP
==>
≈8.5595....
The height of Carl's seat is 11-8.5595...=2.440491...(m)
