2 (hundreds place)
0 (tens place)
0 (ones place)
2 in 200 would be the hundreds place.
The 4 7/8 = 39/8 = 13 pieces of string, he needs 20 so he will need to cut 7 more pieces
Answer:
B. Of the people surveyed that were alive at the time, 90% of them knew exactly where they were when they heard the news.
Step-by-step explanation:
Matrix B has dimensions 4x3
Matrix C has dimensions 3x4
Write out those dimensions like so: 4x3 3x4
The inner '3's match up so B*C is possible. The dimensions of B*C is 4x4 as these are the outer dimensions when lining up 4x3 3x4
Since B*C is a square matrix, it is possible that an inverse could exist. Keep in mind that this isn't a guarantee as the determinant of B*C could be zero (which would lead to BC being non-invertible). Though of course we'd need more info.
