Find the volume of the rectangle:

8 x 2 x 4 = 64 cubic inches.

This means the square can have a volume of 64 cubic inches.

The formula for the volume of a square is V = S^# where S is the length of the side.

Replace V with 64 to solve for S:

64 = S^3

To find S, take the cubic root of 64:

S = ∛64

S = 4

The length of a side is 4 inches.

Answer:

The store will sell it for $58.50

Step-by-step explanation:

To find this amount, start by multiplying the cost by the mark up percentage.

$45 * 30% = $13.50

Now that we have the markup amount, we can add it to the original cost to get the store price.

$45.00 + $13.50 = $58.50

Step-by-step explanation:

Caroline can make 804 full pastrami sandwiches with 201 1/4 pounds of pastrami, using 3/8 of a pound for each sandwich.

To find out how many pastrami sandwiches Caroline can make with 201 1/4 pounds of pastrami, we first need to determine the total number of sandwiches that can be made from a single pound of pastrami. As each sandwich uses 3/8 of a pound, we can calculate this as follows:

1 pound / (3/8 pound per sandwich) = 8/3 sandwiches per pound.

Next, we multiply the number of sandwiches that can be made per pound by the total pounds of pastrami:

201 1/4 pounds * 8/3 sandwiches/pound = 804 sandwiches + 2/3 of a sandwich.

Since Caroline can't make 2/3 of a sandwich, she can make a total of 804 full sandwiches with the pastrami she has.

The order of operations in mathematics ensures that the result of a numerical expression is the same regardless of the order in which the operations are performed. - True

In mathematics, the order of operations is a set of rules that dictate the order in which mathematical operations should be performed in an expression. Following these rules ensures that you always get the same result, regardless of the order in which the operations are performed.

The order of operations, also known as PEMDAS, stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). For example, in the expression 4 + 5 × 2, according to the order of operations, you would perform the multiplication first and then the addition. So, the correct way to evaluate this expression would be 4 + (5 × 2) = 4 + 10 = 14.

Step-by-step explanation:

(1)

we are given

[tex]\lim_{x \to 0} \frac{sin(2x)}{x}[/tex]

Since, we are suppose to find limit x-->0

so, we always choose value of x that is  close to 0

At x=-0.03:

[tex]\frac{sin(2\times (-0.03))}{(-0.03)}=1.99880[/tex]

At x=-0.02:

[tex]\frac{sin(2\times (-0.02))}{(-0.02)}=1.99947[/tex]

At x=-0.01:

[tex]\frac{sin(2\times (-0.01))}{(-0.01)}=1.99987[/tex]

At x=0.01:

[tex]\frac{sin(2\times (0.01))}{(0.01)}=1.99987[/tex]

At x=0.02:

[tex]\frac{sin(2\times (0.02))}{(0.02)}=1.99947[/tex]

At x=0.03:

[tex]\frac{sin(2\times (0.03))}{(0.03)}=1.99880[/tex]

(2)

we are given

[tex]f(x)=\frac{x-4}{x+5}[/tex]

Since, we have to check continuity at a=4

So, firstly we will find limit value and then functional value

Limit value:

[tex]\lim_{x \to a}  f(x)=\lim_{x \to a}\frac{x-4}{x+5}[/tex]

now, we can plug a=4

[tex]\lim_{x \to 4}  f(x)=\lim_{x \to 4}\frac{4-4}{4+5}[/tex]

[tex]\lim_{x \to 4}  f(x)=0[/tex]

Functional value:

We can plug x=4 into f(x)

[tex]f(4)=\frac{4-4}{4+5}[/tex]

[tex]f(4)=0[/tex]

So, we can see that

[tex]\lim_{x \to 4}  f(x)=f(4)=0[/tex]

So, limit value is equal to function value

so, f(x) is continuous at a=4.............Answer

Answer: choice C) 60 degrees

The Synthetic Division form of Given Division Problem is :

✿   [tex]-5\;\arrowvert\overline{\;4\;\;\;\;\;-13\;\;\;\;\;\;8}[/tex]

Option C is the Answer

In synthetic division for [tex]\( \frac{4x^2 - 13x + 8}{x + 5} \)[/tex], option C (-5 | 4 -13 8) correctly represents the coefficients, showcasing the division process with a remainder of 8.

The synthetic division problem given is [tex]\( \frac{4x^2 - 13x + 8}{x + 5} \)[/tex]. Synthetic division is a method used to divide polynomials, particularly when dividing by a linear factor of the form (x - c) . The correct representation in synthetic division form would be:

**C.  -------------

 -  5 | 4   - 13  8**

Here's the breakdown of the synthetic division:

1. The divisor x + 5 corresponds to c = -5, so the root is x = -5.

2. Write down the coefficients of the dividend 4x^2 - 13x + 8 in the synthetic division box.

3. Bring down the leading coefficient, which is 4 in this case.

4. Multiply the root (-5) by the leading coefficient (4) and write the result below the second column. Add the result to the second column.

5. Multiply the root by the result from step 4 and write the result below the third column. Add the result to the third column.

The final result in the bottom row represents the coefficients of the quotient, and the last number (8) is the remainder. The synthetic division in option C accurately reflects this process.

Answer:

Minimum 15 bracelets to be sold to meet the break even.

Step-by-step explanation:

The cost price of bracelets is represented by C(x) =180+8x

The revenue earned (selling price) is represented by R(x) =20x

In these two functions x represents number of bracelets.

If P represents the profit then P = 20x-(180+8x)

P = 20x-180-8x = (12x-180)

For break even profit P = 0

12x-180 =0

12x = 180

x = 180÷12

x = 15

So minimum quantity of bracelets to be sold is 15 for the break even.

2x - 4 > 6    Add 4 on both sides

2x > 10      Divide 2 on both sides

x > 5        (you could stop here and go to the next choice since you know this does not match the graph)

3x < 9     Divide 3 on both sides

x < 3

x > 5 and x < 3

B.)   2x - 4 < 6 and 3x > 9

The compound sentence that has its solution set shown on the graph is 3x + 8 > -7 and -4x < 12.

The solution set for the given compound inequalities is represented by the graph where the shaded region includes the points -1, 0, 1, 2, 3, 4, and 5. The compound sentence that has this solution set is:

3x + 8 > -7 and -4x < 12

Let's break down the compound sentence step by step:

Solve the first inequality: 3x + 8 > -7. Subtract 8 from both sides to get 3x > -15. Divide both sides by 3 to get x > -5.

Solve the second inequality: -4x < 12. Divide both sides by -4 and flip the inequality sign to get x > -3.

Combine the two inequalities by using the word 'and': x > -5 and x > -3.

The solution to this compound sentence is the values of x that satisfy both inequalities, which is x > -3.

Therefore, the compound sentence 3x + 8 > -7 and -4x < 12 has its solution set shown on the given graph.

Answer:

sinB = 8/17

Step-by-step explanation:

sinB = Opposite/Hypotenuse

Here we have to find the opposite side using the Pythagorean theorem.

AB^2 = AC^2 + BC^2

17^2 = AC^2 + 15^2

AC^2 = 17^2 - 15^2

AC^2 = 289-225

AC^2 = 64

Taking the square root on both sides, we get

AC = 8

Opposite side = 8

SinB = 8/17

Answer:

sin B = 8/17

Step-by-step explanation:

sin B can be expressed as the opposite over the hypotenuse in a right triangle.  But we don't know the opposite yet.  We can use the Pythagorean theorem to solve for it

a^2 + b^2 = c^2

15^2 +b^2 = 17^2

225+b^2 = 289

Subtract 225 on each side

225-225 +b^2 = 289-225

b^2 = 64

Take the square root of each side

b=8

The opposite side is 8

sin B = opp/hyp

sin B = 8/17

Answer:

[tex]3m^2+5n^2+8mn[/tex]

[tex]x^2-11x+17[/tex];0

Step-by-step explanation:

We have been given [tex]m^2+3mn−n^2 [/tex] and [tex]4m^2+5mn+6n^2[/tex]

for (1) we will subtract [tex]4m^2+5mn+6n^2[/tex]  from [tex]m^2+3mn−n^2 [/tex]  that is:

[tex]4m^2+5mn+6n^2-m^2+3mn-n^2[/tex]

Now, simplify the like terms we get:

[tex]4m^2-m^2+6n^2-n^2+5mn+3mn[/tex]

After simplification we get:

[tex]3m^2+5n^2+8mn[/tex]

Hence, [tex]3m^2+5n^2+8mn[/tex] is the required result.

(2) Now, we need to find how much less than [tex]3x^2-7x+9[/tex] is [tex]2x^2+4x-8[/tex]

Subtract [tex]3x^2-7x+9[/tex] from [tex]2x^2+4x-8[/tex] we get:

[tex]3x^2-7x+9-2x^2-4x+8[/tex]

After simplifying like terms

[tex]x^2-11x+17[/tex]

When x=2 the the above  expression becomes:

[tex](2)^2-11(2)+17[/tex]

[tex]4-22+17=0[/tex]

For the first question, 4m^2+5mn+6n^2 is 3m^2+2mn+7n^2 greater than m^2+3mn-n^2. For the second question, 3x^2-7x+9 is x^2 -11x + 17 less than 2x^2+4x−8 and the value of the result when x=2 is 12.

For the first question, begin by subtracting the given expressions (m^2 + 3mn - n^2) from (4m^2+5mn+6n^2). This equates to:

(4m^2 + 5mn + 6n^2) - (m^2 + 3mn - n^2) = 3m^2 + 2mn + 7n^2

For the second question, we subtract (2x^2+4x−8) from (3x^2−7x+9). This is equal to:

(3x^2−7x+9) - (2x^2+4x−8) = x^2 -11x + 17

To find the value of the result when x=2, simple plug in '2' wherever x is in the equation, giving the result 17 - 22 + 17 = 12

40% of the pieces of fruit in the Bowl are apples.    

Step-by-step explanation:

Given the statement:- There are 15 pieces of fruit in a bowl and six of them are apples.

⇒ Total number of pieces of fruit  in a bowl = 15 pieces

and  

Number of pieces of apple in a bowl = 6 pieces.

To find the percentage of the pieces of fruit in the Bowl are apples.

[tex]Percentage = \frac{Number of pieces of apple in bowl}{Total number of pieces of fruit in Bowl} \times 100[/tex]

                           = [tex]\frac{6}{15} \times 100 = 40\%[/tex]

Therefore, 40% of the pieces of fruit in the Bowl are apples.

The percentage of apples present in the bowl is [tex]40\%[/tex].

According to the question, there are 15 pieces of fruit in a bowl and 6 of them are apples.

So, the percentage of apples present in the bowl is evaluated as-

[tex]Percentage\;of\;apples=\dfrac{Apples}{Total\;number\;of\;fruits}\times 100\%\\Percentage\;of\;apples=\dfrac{6}{15}\times 100\%\\Percentage\;of\;apples=40\%[/tex]

Step-by-step explanation:

Given :  In ΔTRV , TW ,RU and VS are the medians .

             X is the centroid

To Find : RX and XU

Solution:

Since we know that the centroid divides each median in a ratio of 2:1.

Since X is the centroid so RX : XU = 2:1

So, let RX = 2x and XU = x

And we are given that RU = 18

Answer:  $ 16.96      

Step-by-step explanation:

Here, the present value of the loan, PV = $695.20

Annual Interest rate = 17.9%

⇒ Monthly interest rate = 17.9/12 = 1.41666666667

Thus, the monthly interest rate (decimal ) , r = 0.014167 ( approx)

Monthly payment, P = $ 325

Let the time period of the loan = n.

Since, [tex]P= \frac{r(PV)}{1-(1+r)^{-n}}[/tex]

⇒ [tex]325= \frac{0.014167(695.20)}{1-(1+0.014167)^{-n}}[/tex]

⇒  [tex]1-(1+0.014167)^{-n}= \frac{10.37008984}{325}[/tex]

⇒ [tex]1-(1+0.014167)^{-n}= 0.03190796873 [/tex]

⇒  n = 2.19

Thus, her total payment = 2.19 × 325 =  711.75

⇒ Her total interest = 711.75 - 695.20 = $16.55

Since only 16.96 is near to 16.55

Thus, second option is correct.
