Matrix A order is 4x8.
Matrix B order is 4x16.
AB cannot result because an (m x n) can only be multiplied by an (n x p) matrix and orders don't match the requirements.
BA has the same negative result.
A. 3/5 of the class are girls.
B. 96 of the pupils are boys.
A. To find this answer you subtract 2 from 5 to get 3 (numerator or top of fraction) then use 5 as the denominator or bottom of the fraction.
B. To find this answer, you divide 240 by 5, to show how many pupils are in 1/5 of the class (48). Then multiply 48 by 2, to get the 2/5 of the pupils who are boys (96).
I hope this helps!
The length of the infinite zigzag path is 1
<h3>How to determine the length</h3>
Note that the infinite zigzag path is embedded in an isosceles triangle
Using angle π/4, we have that
Tan π/4 = opposite/ adjacent
To find the longer part 'y', use the Pythagorean theorem
The length of the infinite zigzag path is the same as the length of the longer part of the triangle which equals 1.
Thus, the length of the infinite zigzag path is 1
