Answer: Choice A
This is a 3 by 1 matrix, which can be written "3 x 1 matrix".
There are 3 rows and 1 column. The number of rows is listed first.
Multiply 32X 9 = 288kg
they asked you to convert the kilograms to grams so divide the 288kg by a 1000= 0.288grams
After striking a pair of arcs from each endpoint of a line segment, just join the intersection point of the 1st pair (above the segment) with the intersection point
of the 2nd pair (under the segment)
And this is how you construct the segment's perpendicular bisector
The ratio of 2:9 has to be 2:9 do to the fact you can't simplify the fraction 2/9.
Hoped I helped.
