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.

List all the angle measures from least to greatest.<br><br> From the three triangles

dmitriy555 [2]

Answer:

40°, 43°, 60°

Step-by-step explanation:

In each triangle, you are given the measures of two angles. Subtract those two measures from 180° to find the measure of the third angle.

Triangle A:

c = 180° - 90° - 50°

c = 40°

Triangle B:

c = 180° - 112° - 25°

c = 43°

Triangle C:

c = 180° - 70° - 50°

c = 60°

Carmen has $30 in store bucks and a 25% discount coupon for a local department store. What maximum dollar amount can Carmen purc

hram777 [196]

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is $\boxed{\$ 110}.$

Further Explanation:

Given:

Carmen has $\$ 30$ in store bucks.

A $25\%$ discount coupon for a local department store.

The total amount should be less than $\$ 60$ before sales tax.

Explanation:

Consider the amount of the purchase as A.

The Carmen has $\$ 30$ in store bucks.

The new amount will be $\left( {A - 30} \right).$

There is a $25\%$ discount coupon for a local department store.

The amount after discount can be calculated as follows,

$\begin{aligned}{\text{Amount}} &= \left( {1 - 0.25} \right) \times \left( {A - 30} \right) \\&= 0.75\left( {A - 30} \right) \\\end{alignedd}$

The total amount should be less than $\$ 60$ before sales tax.

The maximum amount can Carmen purchases so that after her store bucks and discount are applied can be calculated as follows,

$\begin{aligned}0.75\left( {A - 30} \right) &\leqslant 60 \\\frac{{0.75\left( {A - 30} \right)}}{{0.75}} &\leqslant \frac{{60}}{{0.75}} \\ A - 30 &\leqslant 80 \\A - 30 + 30 &\leqslant 80 + 30 \\A &\leqslant 110 \\\end{aligned}$

The maximum amount can Carmen purchase so that after her store bucks and discount are applied is $\boxed{\$ 110}.$
