Answer: D. 2/9 - the reason I knew this was smaller was because the numerator(number in the top part of the fraction) stayed the same, but the denominator increased meaning we are dividing the same amount by a larger number of divisions. This means that it will be a smaller fraction.
Why do none of the other answer choices fit? Well, either the numerator increased or both the numerator and denominator increased by a margin that made the final fraction larger than the original 2/5.
when multiplying matrixes the number of columns of the first matrix must be equal as the number of rows of the second matrix, and since here matrix A has 4 columns but matrix B has 5 rows they can't be multiplied
The tree grows 6cm per year and we need to find out how long it will take to grow 1 meter. We know that 1 meter is equal to 100 centimeters. So: 6x = 100 x = 16.67 It will take 16.67 years (or one and two-thirds of a year) for the tree to reach 1 meter.
