Answer:

$60

Step-by-step explanation:

11 identical pairs of Air Jordan cost $660.

To find the cost of one pair, you have simply to divide the total amount paid by the total number of pairs.

Total amount paid = $660

Total number of pairs = 11

The cost of one pair [tex]=\$660 : 11=\$60[/tex]

To find the cost of one pair of Air Jordan sneakers from the total cost of 11 pairs, divide the total cost ($660) by the number of pairs (11), which equals $60 per pair.

The question concerns determining the cost of one pair of Air Jordan sneakers given the total cost for 11 pairs. This is a basic division problem that falls under the category of arithmetic in mathematics. To find the cost of one pair, divide the total cost by the number of pairs. Here is how the calculation is done step-by-step:

Therefore, the cost for one pair of Air Jordan sneakers is $60.

Volume of sphere having radius of 3 inches is 113.04 cubic inches.

Solution:

Given that the radius of a sphere is 3 inches. Need to determine the volume of sphere

Formula for volume of sphere is as follows :

[tex]V=\frac{4}{3} \pi r^{3}[/tex]

Where V is volume of sphere , π is constant value = 3.14 and r = radius of a sphere.

In our case, r = 3 inches

On substituting the value of π as 3.14 and value of r as 3 inches in the formula of volume of sphere, we get

[tex]V=\frac{4}{3} \times 3.14 \times 3^{3}=4 \times 3.14 \times 9=113.04 \text { cubic inches }[/tex]

Hence volume of sphere having radius of 3 inches is 113.04 cubic inches.

Answer:

Option A is correct.

Step-by-step explanation:

See the two graphs given in the diagram attached.

The first graph shows the function f(x) = x²

Hence, it passes through the points (1,1), (-1,1), (2,4) and (-2,4) points.

Now, from the plotted second graph we see the points (2,2), and (-2,2) are on the curve.

Hence, the y-value corresponding to the same x-value reduces by a factor [tex]\frac{1}{2}[/tex] in the second graph i.e. the graph of y = g(x) compared to the first graph.

So, we can conclude that the transformed graph has the equation [tex]g(x) = \frac{1}{2} x^{2}[/tex].

Hence, option A is correct. (Answer)

Answer:

The answer is g(x) = (1/2) x^2

Answer:

45 Miles

Step-by-step explanation:

3 hours * 15mph= 45 Miles in 3 hours

For this case we have the following system of equations:

[tex]x-5y = 33\\5x-6y = 70[/tex]

We multiply the first equation by -5:

[tex]-5x + 25y = -165[/tex]

Thus, we have the equivalent system:

[tex]-5x + 25y = -165\\5x-6y = 70[/tex]

We add the equations:

[tex]-5x + 5x + 25y-6y = -165 + 70\\19y = -95\\y = - \frac {95} {19}\\y = -5[/tex]

We find the value of the variable "x":

[tex]x-5 (-5) = 33\\x + 25 = 33\\x = 33-25\\x = 8[/tex]

Thus, the solution of the system is:

[tex](x, y) :( 8, -5)[/tex]

Answer:

[tex](x, y) :( 8, -5)[/tex]

Answer:

[tex]n = 3[/tex]

Step-by-step explanation:

Given:

The equation given is:

[tex]p^3q^2(p^4q^n\times \frac{r^3}{r^{-4}})=p^7q^5r^7[/tex]

We simplify the given equation using the following law of indices:

[tex]a^m\times a^n=a^{m+n}\\\frac{a^m}{a^n}=a^{m-n}[/tex]

Therefore,

[tex]p^{3+4}q^{n+2}\times r^{3-(-4)})=p^7q^5r^7\\p^7q^{n+2}r^7=p^7q^5r^7\\q^{n+2}=q^5[/tex]

Since the base on both the sides is same, therefore, their exponents must also be same. This gives,

[tex]n+2=5\\n=5-2\\n=3[/tex]

Therefore, the value of 'n' is 3.

Answer:

To find the cost of 24 candy bars, calculate the cost per candy bar (found by dividing $20 by 16, equaling $1.25) and multiply it by 24. Therefore, 24 candy bars would cost $30.

The subject of the question involves unit pricing, a common concept in mathematics. To find the cost of 24 candy bars, first identify the cost per candy bar, then multiply this unit price by the number of candy bars in question.

From the question, we know that 16 candy bars cost $20. So the unit price, or cost per candy bar, is $20 divided by 16, which equals $1.25.

Therefore, the cost of 24 candy bars would be $1.25 (the cost per candy bar) multiplied by 24 (the number of candy bars), which equals $30. Hence, 24 candy bars would cost $30.

Step-by-step explanation:

We have labelled the given diagram and redrawn again in the attachment.

Also from the labelled diagram given below the given details are;

∠CPQ =[tex](5y-4)\°[/tex]

∠RQF =[tex]3y\°[/tex]

∠BRH =[tex](2x+13)\°[/tex]

∠CPQ = ∠PQF  (Alternate Interior Angle)

∠PQF + ∠RQF =180° (Straight angle property)

Now Substituting the values we get;

[tex]5y-4+3y=180\\8y=180+4\\8y=184\\y=\frac{184}{8}=23\°[/tex]

∠RQF =[tex]3y\° = 3\times23 = 69\°[/tex]

∠RQF = ∠BRH (corresponding angles)

[tex]69=2x+13\\2x = 69 -13\\2x=56\\x = \frac{56}{2} = 23\°[/tex]

Answer:

C. y +3 = x +3

Step-by-step explanation:

We need to find in below option x has direct variation with y.

We solve for each;

A. [tex]2y = 3x-7[/tex]

From above equation we can state that 2 times y is equal to 7 less than 3 times of x.

Hence it doesn't represent direct variation.  

B. [tex]y-4 = x+6[/tex]

Solving above expression we get;

[tex]y-4 = x+6\\y = x+6+4\\y=x+10[/tex]

From above equation we can state that y is equal to 10 more than x.

Hence it doesn't represent direct variation.

C. [tex]y+3 = x+3[/tex]

Solving above expression we get;

[tex]y+3 = x+3\\y = x+3-3\\y=x[/tex]

From above equation we can state that y is equal to x.

Hence it represent direct variation.

D. [tex]4y+1 = 4x-1[/tex]

Solving above expression we get;

[tex]4y+1 = 4x-1\\4y = 4x-1-1\\4y=4x-2[/tex]

From above equation we can state that 4 times y is equal to 2 less than 4 times of x.

Hence it doesn't represent direct variation.

Hence the Answer which represent direct variation of x and y is,

C. [tex]y+3 = x+3[/tex]
