Answer:

36 comic books and 339 Pokemon cards

Step-by-step explanation:

Let number of comic books be [tex]x[/tex] and number of Pokemon cards be [tex]y[/tex].

Total number of comic books and Pokemon cards is [tex]375[/tex]. So we get the equation

[tex]x+y=375\\\Rightarrow y=375-x[/tex]

Cost of one comic book is $5.79 and one Pokemon card is $3.35.

They need to make $1345 so we get the equation

[tex]5.79x+3.35y=1345\\\Rightarrow 5.79x+3.35(375-x)=1345\\\Rightarrow 5.79x-3.35x+3.35\times 375=1345\\\Rightarrow x=\dfrac{1345-3.35\times 375}{5.79-3.35}\\\Rightarrow x=36.37\approx 36[/tex]

[tex]y=375-x=375-36\\\Rightarrow y=339[/tex]

So, they need to sell approximately 36 comic books and 339 Pokemon cards.

Step-by-step explanation:

Answer: y = 6; x = 12

Step-by-step explanation:

3x - 30 = y

Change this into an equation where x and y are in the same side.

3x - 30 = y

Subtract y from both sides

3x - y - 30 = 0

Add 30 to both sides

3x - y = 30

7y - 6 = 3x

Do the same thing I did to the first equation

7y - 6 = 3x

Subtract 3x from both sides

-3x + 7y - 6 = 0

Add 6 to both sides

-3x + 7y = 6

We can now use the system of elimination to find x and y.

3x - y = 30

-3x + 7y = 6

After adding both equations, you get:

6y = 36

Divide 6 from both sides

y = 6

Since we now know y, we can solve for x.

3x - 30 = y

Substitute y for 6

3x - 30 = 6

Add 30 to both sides

3x = 36

Divide both sides by 3

x = 12

Hope this helped!

Answer:

[tex]x = 12.y = 6[/tex]

Step-by-step explanation:

Restructuring

[3x - 30 = y

-3x - 6 =7y

[tex] \frac{ - 36}{ - 6} = \frac{ - 6y}{6} [/tex]

y=6

Sub 6 in equ II

7(6)-6=3x

[tex] \frac{36}{3} = \frac{3x}{3} [/tex]

x=12

Please check explanations for answer

Step-by-step explanation:

Here, we want to show that the left hand side equals the right hand side

We can express the left hand side as:

sin A/ cos A * sec A/cosec A

kindly recall that;

sin A/cos A = tan A

Also;

sec A = 1/ cos A

cosec A = 1/ sin A

Thus, we have that ;

tan A * 1/cos A / 1 / sin A

= tan A * sin A/cos A

This is;

tan A * tan A = tan^2 A

Answer:  [tex]\frac{\sqrt{3}}{2}[/tex]

======================================================

Explanation:

The symbol [tex]\theta[/tex] is the greek letter theta. It's often used in trigonometry for angles.

In this case, [tex]\theta = 30^{\circ}[/tex]

So,

[tex]\cos(\theta) = \cos(30^{\circ}) = \frac{\sqrt{3}}{2}[/tex]

You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.

When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how [tex]\frac{\sqrt{3}}{2}[/tex] is the x coordinate of the terminal point. This is due to [tex]x = \cos(\theta)[/tex]

Side note: [tex]\frac{\sqrt{3}}{2} \approx 0.866025[/tex]

Step-by-step explanation:

Equation of circle: (x + 2)² + (y - 2)² = r²

Radius of the circle is 3 (from -2 to 1).

Hence we have

(x + 2)² + (y - 2)² = 3² or (x + 2)² + (y - 2)² = 9.

Answer: A for the first part and B for the second part

Step-by-step explanation:

Answer:

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

Step-by-step explanation:

Given that:

Part A:

Original price of video game = $32.99

Discounted price = $26.39

Amount of discount = 32.99 - 26.39 = $6.60

Discount percent = [tex]\frac{Amount\ of\ discount}{Original\ price}*100[/tex]

Discount percent = [tex]\frac{6.60}{32.99}*100 = 0.20*100[/tex]

Discount percent = 20%

Part B:

Sales tax = 8% of discounted price

Amount of sales tax = [tex]\frac{8}{100}*26.39 = 0.08*26.39[/tex]

Amount of sales tax = $2.11

Total amount = $26.39 + $ 2.11 = $28.50

Hence,

Part A: The percent discount on game is 20%.

Part B: Mario paid a total of $28.50 including sales tax.

Answer:

400 megabytes of data used will make the cost from either company equal.

Step-by-step explanation:

Given that:

Per month charges of Company A = $80

Charges of 100 MB = $5 = [tex]\frac{5}{100}=\$0.05\ per\ MB[/tex]

Let,

x be the number of MBs consumed.

y be the total charges.

y = 0.05x+80

Per month charges of Company B = $60

Charges of 100 MB = $10 = $0.1 per MB

y = 0.1x+60

For equal charges;

0.05x+80 = 0.1x + 60

80-60 = 0.1x-0.05x

20 = 0.05x

[tex]\frac{0.05x}{0.05}=\frac{20}{0.05}\\x=400[/tex]

Hence,

400 megabytes of data used will make the cost from either company equal.

Answer:

that's features that correctly stated.

Answer:

a. Monthly profit is

(x-35)(500-x)

b. given x = 85, the profit is 20,750 pesos

Step-by-step explanation:

a. The monthly profit is the selling price - cost price

The cost price for the number of dolls made will be ;

35(500-x)

The value of the amount we are selling all is;

x(500-x)

So the monthly profit would be;

x(500-x)-35(500-x)

= (x-35)(500-x)

b. Given the selling price we 85 , we want to calculate the monthly profit

From

what we have, x will be 85

Substituting in the equation we have for A above, we have that;

(85-35)(500-85)

= 50* 415 = 20,750 pesos

Answer:

The rule for the linear function wil be:

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points

Finding the slope between (0, 0) and (1, 1)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [1 - 0] / [1 - 0]

                 = 1 / 1

                 = 1

Thus, the slope of the line = m = 1

We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 0

Thus, the y-intercept b = 0

Now, substituting m = 1 and b = 0 in the slope-intercept form of linear function

y = mx+b

y = (1)x + 0         ∵ m = 1, b = 0

y = x

f(x) = x     ∵

Therefore, the rule for the linear function wil be:
