Answer:

5 X 5

Step-by-step explanation:

The dimensions of a matrix $$ \implies$ number of rows and columns of that matrix. If it is as an $m \times n$ (read as $m$ by $n$ it means that it has $m$ number of rows and $n$ number of columns.

In the given problem, the rows and columns are 5. So, we write it is a $5 \times 5$ matrix. We call it a Square matrix, since the number of rows equals the number of columns.

Dots sells a total of 277 T-shirts ($2) and shorts ($3). In April, total sales were $656.

icang [17]

Answer:

Shorts = 112 and t shirts = 165

Step-by-step explanation:

Let S = shorts

Let T = t shirts

T + S = 277

$2T + $3S = $656

-2(T + S) = 277 so -2T -2S = -544

2T + 3S = 656 so 2T + 3S = 656

------------------------

SO: (subtract T's cancel out) 1S = 112

divide by 1 so S = 112

Plug S into the top equation: T + s = 277 T + 112 = 277 so T = 165

George bought socks for "$"300 and planned to sell them for $6 a pair. write an inequality to find the minimum number of socks h

Anit [1.1K]

The inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

In the question, we are given that George bought socks for $300.

Therefore, George's total cost = $300.

We assume the number of pairs of socks George sells to be s.

The unit price per pair quoted by George = $6

Therefore, George's total sales = $6s.

We know that the profit over a transaction is given as the difference between sales and costs, that is,

The profit = The total sales - the total costs,

or, profit = 6s - 300.

In the question, we are required to make a profit of more than 210.

This can be shown by the inequality,

6s - 300 > 210.

Thus, the inequality 6s - 300 > 210 represents the minimum number of socks (s) when George bought socks for "$"300 and planned to sell them for $6 a pair, and want to make a profit of more than 210.

I need help to these questions. Convert these fractions to a decimal 7/8 , 4 3/8. Thanks

ehidna [41]

Simple...

you have: $\frac{7}{8}$ and $4 \frac{3}{8}$

Now, the first one is easy just divide it...

$\frac{7}{8} =0.875$

Now....

$4 \frac{3}{8}$ needs to be converted...

Multiply the whole number*denominator...

4*8=32

Now add the numerator....

32+3=35

Now use the original denominator...

$\frac{35}{8}$

Now divide...

$\frac{35}{8}=4.375
$

Thus, your answer.

Find m3 if m5 = 38° and m6 = 62°.

geniusboy [140]

M5 minus M6 will get M1
So 62 - 38 = 24
24 x 3 = 72
So M3 is 72

Solve for x in the diagram below.

max2010maxim [7]

1: Identify the angle.

The following angle is a 90.

2: Set up the equation.

x + (3x + 10) = 90

3: Combine like terms.

4x + 10 = 90

4: Solve for x.

4x + 10 = 90

-10 = - 10

--------------------------

4x = 80

------------------

4 4

x = 20

Your answer is x = 20.

Hope this helps! Have a good day/night! c:
