2x + 3y = 1200
3x + 2y = 1300
Based on the system of equations above, what is the
value of 5x+ 5y?​

In this situation, where the price of the soda remains constant regardless of the number of refills, the slope of the function representing this scenario is 0.

In mathematics, the slope of a function can be thought of as the rate of change of the dependent variable (in this case, cost) in relation to the independent variable (in this case, number of refills). Given that the price for the soda remains constant at $3 regardless of the number of refills, the slope would be 0. This is because the cost (the y-value) does not change as the number of sodas (the x-value) increases. Thus, the correct answer is 1) 0.

Answer:

The surface area of the rectangular prism is 256

Step-by-step explanation:

Answer:

256 yd2

Step-by-step explanation:

The statement is false because parabolas can also open upwards or downwards if the directrix is horizontal. A parabola's open direction depends on the position of the directrix relative to the focus.

The statement that "All parabolas with vertical directrix open to the left or right" is false. A parabola's orientation is determined by the position of its directrix in relation to its focus. If you have a vertical directrix, the parabola will indeed open to the left or the right, depending on the side of the directrix the focus lies. However, if the directrix is horizontal, the parabola will open upwards or downwards. To help understand this, recall that the directrix serves as a line that, in combination with the focus, defines the set of points that make up the parabola—that is, points equidistant from both the focus and the directrix. Furthermore, the equation of a parabola can change based on the orientation and position of the axis, the focus, and the directrix, as shown in various figures and equations related to parabolic motion and geometry.

Answer:

20% increase

Step-by-step explanation:

1- New number-original number

2- number increased divided by new number then multiply by 100

15-12= 3

3 divided by 15= 0.2

0.2 times 100= 20%

If an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

Given that, an original quantity is 12, and the new quantity is 15.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here,

Percentage increase = (New quantity - Original quantity)/Original quantity ×100

= (15-12)/12 ×100

= 3/12 ×100

= 0.25×100

= 25%

Therefore, if an original quantity is 12, and the new quantity is 15, then the percentage increase is 25%.

Median=12

The data set could be as follow 7,7,12,12,12 which has a mean of 10 and a median of 12.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

we have given the information of the data set with five numbers that have a mean of 10 and a median of 12.

Mean = 10

Let's assume the given data set 7,7,12,12,12 so, this must satisfy the information

7+7+12+12+12=50/5

Mean =10

Also,

Median=12

Thus, the data set could be as follow 7,7,12,12,12 which has a mean of 10 and a median of 12.

Answer:

32 cubic meter

Step-by-step explanation:

Volume  for any pyramid  is given by  following expression

volume of pyramid = 1/3( area of base of pyramid * height of pyramid)

________________________________

In the problem

base area of pyramid = 24 sq. m

height = 4 m

Therefore substituting the above given value in formula for volume of pyramid we have

volume of pyramid = 1/3( 24 sq. m * 4 m) = 8 sq. m * 4 m   (since 24/3 = 8)

volume of pyramid =  32 cubic meter.

Step-by-step explanation:

Those angles are co interior, and thus add up to 180°. So therefore:

(x+72) + 3x = 180

so 180 - 72 = 108

4x = 108

x = 27

choice A:   y = 25*x

Step-by-step explanation:

A proportional relationship between x and y  would be  y = 25*x

because   y/x = 25  (a constant)

We could say that   y = 2x  + 0.5   can be a proportion relationship,  but not between y and x directly.

y=  2* x  +  2* (1/4)  =  2* (x + 1/4)

and get :    y / (x + (1/4) )  = 2     y  and  (x + (1/4)) are in a proportional relationship,  except it would not be y and x  .

Answer:

0.013 M NaOH

Step-by-step explanation:

HCL + NaOH = NaCL + water

The mole ratio of acid and base is 1:1

Molarity is equal to the moles of solute divided by the liters of solution

Solute mole = 12.5 × 10^-3 × 0.3

= 0.003075

To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:

Molarity = 0.00375/285 × 10^-3

Molarity = 0.0131 M

The molarity concentration of the NaOH solution is 0.013M NaOH

The equation of reaction is given as:

[tex]HCl + NaOH >>>>>> NaCl + H_2O[/tex]

Concentration of Hcl, [tex]C_{Hcl}=0.30M[/tex]

Volume of Hcl, [tex]V_{HCl}=12.5mL[/tex]

Concentration of NaOH = [tex]C_{NaOH}[/tex]

Volume of NaOH, [tex]V_NaOH = 285mL[/tex]

From the equation of reaction:

Number of moles of Hcl, [tex]n_{HCl}=1[/tex]

Number of moles of NaOH, [tex]n_{NaOH}=1[/tex]

The formula for neutralization is given as:

[tex]\frac{C_{HCl}V_{HCl}}{C_{NaOH}V_{NaOH}} = \frac{n_{HCl}}{n_{NaOH}}[/tex]

Substitute the values of the parameters

[tex]\frac{0.30(12.5)}{C_{NaOH}(285)} =\frac{1}{1} \\\\C_{NaOH}(285) = 0.30(12.5)\\\\C_{NaOH}(285) = 3.75\\\\C_{NaOH}=\frac{3.75}{285} \\\\C_{NaOH} = 0.013M[/tex]

The molarity concentration of the NaOH solution is 0.013M NaOH

Answer:

  -4, 2, 8, 14, 20

Step-by-step explanation:

The rule is called a "position to term" rule. That means the word "position" is being used to identify the location of a term in the sequence. The first term is in position 1, for example. Using the rule that the position is multiplied by 6, then 10 is subtracted, we find the terms to be as follows.

In position 1, the term is ...

  1×6 -10 = -4

In position 2, the term is ...

  2×6 -10 = 2

In position 3, the term is ...

  3×6 -10 = 8

In position 4, the term is ...

  4×6 -10 = 14

In position 5, the term is ...

  5×6 -10 = 20

The first 5 terms are -4, 2, 8, 14, 20.

12 multiple choice questions

Step-by-step explanation:

The system of equations is:

m + t = 19 (quantity of questions)

6m + 4t = 100 (point value)

We use elimination to solve.

Multiply everything in the first equation by 4.

4m + 4t = 76.

subtract that from the second equation.

2m = 24

Divide both sides by 2.

m = 12

Answer:

Step-by-step explanation:

Let x be the number of true or false questions.

Let y be the  number of multiple choice questions

Total questions = 19

x + y = 19   ---------------(i)

Total points = 100

4x + 6y = 100  ---------------(ii)

Multiply equation (i) by (-4).

(i)*(-4)            -4x - 4y = -76

(ii)                  4x + 6y = 100   {Now add. thus x will get eliminated}

                            2y = 24

y = 24/2

y= 12
