25 000,000/10,000
Cross out equal amounts of 0's from both numbers:
There are 4 0's in 10,000, so remove 4 0's from both numbers to get:
2500/1
Any number over 1 is that number:
2500/1 = 2500

Answer:
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
Step-by-step explanation:
A square matrix is where the number of rows is equal to the number of columns like order 2x2, 3x3, 4x4, 5x5 etc.
Given options are:-
A) A shoe salesperson wants to use an augmented matrix to represent the quantity of children’s shoes and adult shoes sold at his store for two days.
It is 2x2 times 2x1 = 2x1 matrix.
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
It is 6x1 times 1x6 = 6x6 matrix.
C) A student wants to write a coefficient matrix representing a linear system with two equations and three unknowns.
It is 2x3 times 3x1 = 2x1 matrix
D) A teacher wants to write an augmented matrix representing a linear system with four equations and four unknowns.
It is 4x4 times 4x1 = 4x1 matrix.
Hence option B is correct.
Answer:
28cm^2
Step-by-step explanation:
The first thing we will do is split this shape into three different rectangles. You can see how I split it up by looking at the picture attached to this answer.
You can see that we are missing a measurement at the bottom (I labeled it "x"). In order to find x, we just need to subtract 3cm from 5cm.
Doing this, we find that x = 2cm.
Now you just find the area of the three boxes and add them together.
The area of the box on the top right = 3*2 which = 6cm^2.
The area of the box on the bottom right is the same. 3*2=6cm^2
The area of the box on the left = 8*2 which = 16cm^2.
6 + 6 + 16 = 28cm^2
