[tex]a_{1,3} = 9[/tex]

Step-by-step explanation:

The elements of matrices are represented in the form

[tex]a_{r,c}[/tex]

Here r is the row number and c is the column number.

Given matrix is:

[tex]A = \left[\begin{array}{ccc}3&6&9\\2&4&8\end{array}\right][/tex]

The elements of matrix will be represented by a_{r,c}

We have to find [tex]a_{1,3}[/tex]

Which means that the first row and third column.

The first row is: 3   6    9 and the element in third column is: 9

So,

Answer:

The number of movies that can can fit on shelf of 5 feet is 9 .

Step-by-step explanation:

Given as :

The measure of each movies case = 7 inches wide

Let the number of movies for 5 feet wide = n

Now ,

∵ 1 feet = 12 inches

∴ 5 feet = 12 × 5 = 60 inches

I.e 5 feet = 60 inches

Now, Again

For 7 inches wide  , the number of movies = 1

So, for 1 inch wide case, the number of movies = [tex]\frac{1}{7}[/tex]

∴ For 60 inches wide case, the number of movies = [tex]\frac{1}{7}[/tex] × 60

I.e For 60 inches wide case, the number of movies = 8.57 ≈ 9

Hence the number of movies that can can fit on shelf of 5 feet is 9 . Answer

Answer:

The value of x  in the given figure is  110°

Step-by-step explanation:

Here, In ΔABD,

AB=AD and  ∠ ABD =  35°

Now, ANGLES OPPOSITE TO EQUAL SIDES ARE EQUAL.

      As,  AB=AD

⇒ ∠ ABD =   ∠ ADB =    35°  

Now, In ΔABD,  by ANGLE SUM PROPERTY:

∠ ABD  + ∠ ADB +   ∠ DAB  =  180°

⇒ 35°   + 35°   + x  = 180°  

or,  x = 180°  - 70°  = 110°

⇒ x  = 110°

Hence, the value of x  =  110°

Answer:

110

Step-by-step explanation:

Since AB=AD, AB = 35 so that means AD = 35. 35+35=70. A triangle is 180, so 180-70=110

Answer: [tex]\frac{11}{12}[/tex]

Step-by-step explanation:

Since we are looking for the total fraction completed , all we need do is to add the fraction completed last month and the fraction completed this week , that is

[tex]\frac{2}{3}[/tex] + [tex]\frac{1}{4}[/tex]

The L.C.M is 12 , so we have

[tex]\frac{2}{3}[/tex] + [tex]\frac{1}{4}[/tex] =[tex]\frac{8 +3}{12}[/tex]

= [tex]\frac{11}{12}[/tex]

Therefore 11/12 is completed

Answer:

You completed 11/12 of your project.

Step-by-step explanation:

Change into a common denominator: 2/3 = 8/12 and 1/4 = 3/12

8/12 + 3/12 = 11/12

The slope-intercept form for given equation is:

[tex]y = -\frac{7}{8}x-6[/tex]

Step-by-step explanation:

Given equation is:

[tex]7x+8y = -48[/tex]

The given equation is in standard form. The slope-intercept form is:

[tex]y =mx+b[/tex]

Ao, to convert the given equation to slope-intercept form

Subtracting 7x from both sides

[tex]7x-7x+8y = -7x-48\\8y = -7x-48[/tex]

Dividing both sides by 8

[tex]\frac{8y}{8} = \frac{-7x-48}{8}\\y=-\frac{7}{8}x-\frac{48}{8}\\y = -\frac{7}{8}x-6[/tex]

The slope-intercept form for given equation is:

[tex]y = -\frac{7}{8}x-6[/tex]

There were 26,101 people in the athletic center at the end of game.

Step-by-step explanation:

Number of people entered = 24196

Number of people left during second half = 2914

Remaining people = 24196 - 2914 = 21282

People entered during second half = 4819

Total people at the end of game = Remaining people + People entered during second half

Total people at the end of game = [tex]21282+4819=26101[/tex]

Answer:

The number of roots for  equation [tex]5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex] is 4 .

Step-by-step explanation:

Here, the given function polynomial is :

[tex]P(x) : 5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex]

The Fundamental Theorem of Algebra says that a polynomial of degree n will have exactly n roots (counting multiplicity).

Now here, the degree if the polynomial is 4 (highest power of variable x).

So, according to the Fundamental Theorem, the given polynomial can have AT MOST 4 roots, counting Multiplicity.

Hence,  the number of roots for  equation [tex]5x^4 + 12x^3 – x^2 + 3x + 5 = 0[/tex] is 4 .

Final answer:

The student's request for fractions between -8/10 and -4/5 cannot be fulfilled because these two fractions are equivalent. To provide a meaningful answer, it's assumed that the intended question is to find fractions between -8/10 and -9/10, for which examples are given.

Explanation:

The question is asking for five fractions that are between -8/10 and -4/5. First, notice that -8/10 is equivalent to -4/5, so we actually need to find fractions between two identical values. This is not possible as no fractions can exist between two identical numbers. However, assuming that the question intends for incremental fractions between two different numerators with the same denominator, we could consider finding fractions between -8/10 and -9/10, or between -7/10 and -8/10.

For simplicity, let's find five fractions between -8/10 and -9/10:

-17/20

-18/20

-19/20

-39/40

-79/80

These fractions are chosen because they simplify to values that lie between -8/10 and -9/10 when reduced to the same denominator.

Answer:

6 people

Step-by-step explanation:

Since the resort has 380 rooms with space for 6 people, only 6 people can be in these rooms at the same time.

Note: It was not said that each room has space for 6 people but the hotel has space for 6 people

Irrespective of the number of rooms available, the space limit is 6, hence not more than 6 people can be accommodated.

Answer:

Step-by-step explanation:

240 / 15 = 16 packs

Answer:

(4, 0)

Step-by-step explanation:

To use elimination, you need to make the coefficients of one of the variables the same in each equation.  For example, we can multiply the first equation by 2 and the second equation by 3:

6x + 4y = 24

6x + 15y = 24

Now we can subtract the equations, eliminating the x terms.

(6x + 15y) − (6x + 4y) = 24 − 24

11y = 0

y = 0

Now plug into either equation to find x.

3x + 2y = 12

3x + 0 = 12

x = 4

the solution is y = 7

Step-by-step explanation:

Given equation is

[tex]8+5y=(8y-6)-7[/tex]

The equation has to be solved for y

So,

Opening brackets first

[tex]8+5y=8y-6-7\\8+5y=8y-13[/tex]

Subtracting 8 from both sides

[tex]8+5y-8=8y-13-8\\5y=8y-21[/tex]

subtracting 8y from both sides

[tex]5y-8y = 8y-21-8y\\-3y=-21y[/tex]

Dividing both sides by -3

[tex]\frac{-3y}{-3} = \frac{-21}{-3}\\y = 7[/tex]

so,

the solution is y = 7

Answer:

Step-by-step explanation:

The last one

The equation 7 - x = 3 is best modeled by the situation where the original price of a book at $7 is lowered by an amount of $4 to reach the final price of $3.

The given equation 7 - x = 3 can be used to model a situation where the price of a book, originally $7, is reduced by some amount to $3. After solving the equation by subtracting 7 from both sides and then multiplying by -1, we get x = 4. This means the amount reduced from the original price is $4, which is consistent with a price reduction scenario: the book's original price was $7, and it was reduced by $4, bringing the final price to $3.

Just make sure that the line goes 4 unit to the right as it goes 3 units up.

y=3/4x: (0,0) and (4,3)

y=3/4x+1: (0,1) and (4,4)

Answer:

No solution.

Step-by-step explanation:

Add similar elements: 2y + 3y = 5y

5y - 6 (y + 2) = -y + 6

Apply the distributive Law:

6y - 6 x 2 = 6y - 12

5y - 6y - 12 = -y + 6

Add similar elements: 5y - 6y = -y

-y - 12 = -y + 6

Add 12 to both sides:

-y - 12 + 12 = -y + 6 + 12

Simplify:

-y = -y + 18

Add y to both side:

-y + y = -y + 18 + y

Simplify:

0 = 18
