Answer:

Step-by-step explanation:

Since we have given that

Number of styrofoam balls bought by Bradley in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought by Lupe in June = 44

Number  of toy figurines sold in June = 21

So, we need to make a matrix that represents all of their May purchases and their June sales :

So, it is given by

                       May                    June

                    Purchases             Sales     

 Bradley       48                            19

 Lupe            49                           21

Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be

\left[\begin{array}{ccc}48-19\\44-21\end{array}\right]

Step-by-step explanation:

Since we have given that

Number of styrofoam balls bought in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought in June = 44

Number  of toy figurines sold in June = 21

So, we need to make a matrix that represents all of their May purchases and their June sales :

So, it is given by

                        May                    June

                     Purchases             Sales     

 Bradley      48                            19

 Lupe           49                           21

Hence, the proper matrix will be

\begin{bmatrix}48 &19 \\ 49&22 \end{bmatrix}

Which number produces a rational number when added to 0.3?
Monica [59]
A rational number is an algebraic term expressed as a fraction. The fraction can also be in decimals but only if the decimal places are not repeating or not infinitely long. If they aren't, then these are called irrational numbers.

Let's try each of the choices:

A. The term 2/4 is a rational number. Now, when 0.3 or 3/10 is added to it, the sum would be 4/5 or 0.8. This is a rational number.

B. √7 is an irrational number because its exact value is 2.645751311.... Even if you add 0.3 to it, the answer would still be irrational

C. Obviously, this is an irrational number

D. The exact value of π is <span>3.14159...... If 0.3 is added to it, the answer would be 3.441592654. This is irrational.


Therefore, the answer is A.</span>

2. An expression is shown.
laiz [17]

Adding parentheses in the component 9\div 3 of the expression may bring an output of 48.

<h3>Procedure - Application of hierarchy rules in a arithmetic expression</h3>

In this question we should make use of hierarchy rules represented by the use of parentheses. The parentheses oblige to make operations inside it before making it in the rest of the formula.

Now we decide to add parenthesis in the component 9\div 3 such that the result of the entire expression is 48. We proceed to present the proof:

2 \times 8 \times (9\div 3)

2\times 8 \times 3

2\times 24

48

Adding parentheses in the component 9\div 3 of the expression may bring an output of 48. \blacksquare

<h3>Remarks</h3>

The statement presents mistakes and is poorly formatted. Correct form is shown below:

An expression is shown: 2\times 8 \times 9 \div 3

Using the same expression, add parenthesis so that the value of the expression is 48.
