There aré 23 students and a student admission ticket is 8$ how much will the student tickets cost

Answer:

1/6

Step-by-step explanation:

The student's question pertains to calculating fuel economy, which is found by dividing the distance traveled by the amount of fuel used. We find that the first vehicle gets 24 mpg and the second one gets 25.33 mpg. This calculation is useful for comparing vehicle efficiency and managing fuel costs.

The question involves calculating fuel economy, which is a mathematical concept generally taught in high school Algebra or Applied Math classes. Fuel economy is calculated by dividing the distance traveled by the amount of fuel used. For example, for the first vehicle that traveled 96 miles on 4 gallons, the fuel economy is calculated as follows:

Divide the total miles by the gallons used: 96 miles / 4 gallons = 24 miles per gallon (mpg).

Similarly, for the second vehicle that traveled 380 miles on 15 gallons, we calculate fuel economy like this:

Divide the total miles by the gallons used: 380 miles / 15 gallons = 25.33 mpg.

This practice of tracking fuel economy is useful for comparing the efficiency of different vehicles, as shown in the examples of the Toyota Prius and Ford Fusion hybrid. Additionally, knowing your vehicle's fuel economy and the average fuel cost can help you budget for fuel purchases more effectively

y < - 8  or y > 4

inequalities of the form | x | > a always have solutions of the form

x < - a or x > a

we have to solve

y + 2 < - 6 or y + 2 > 6

y + 2 < - 6 ( subtract 2 from both sides )

y < - 8

or

y + 2 > 6 ( subtract 2 from both sides )

y > 4

these can be combined using interval notation

y ∈ (- ∞, - 8 ) ∪ (4, ∞ )

As a check

substitute chosen values of x from each interval

y = - 10 :  | - 10 + 2 | = | - 8 | = 8 > 6 this is true

y = 12 : | 12 + 2 | = | 14 | = 14 > 6 which is also true

Answer:

It will take 4.5 hours for Naomi and Clair to paint an equal number of square feet

Explanation:

 Let the time in hour it will take for Naomi and Clair to paint an equal number of square feet be t hours.

Naomi paints 16.5 square feet of a mural at a rate of 2 square feet per hour, so after t hours the are painted by Naomi = 16.5 + 2 * t

Clair paints 7.5 square feet of the mural at a rate of 4 square feet per hour, so after t hours the are painted by Clair = 7.5 + 4 * t

We know that after hours the area painted by them are equal, so we have

           16.5 + 2 * t = 7.5 + 4 * t

            2 * t = 16.5 - 7.5 = 9

                t = 4.5 hours.

  So it will take 4.5 hours for Naomi and Clair to paint an equal number of square feet.                          

If Naomi and Clair continue to paint at their current rates, it will take approximately 4.5 more hours for both to have painted an equal amount of the mural.

First, let's calculate how much Naomi and Clair have already painted. Naomi has painted 16.5 square feet and Clair has painted 7.5 square feet. Now, calculate the difference which is 9 square feet.

Every hour, Naomi paints 2 square feet and Clair paints 4 square feet. However, since Clair needs to catch up by 9 square feet, we need to consider the extra square feet Clair paints per hour, which is 2 (4 - 2).

So, to find out how many more hours it will take for them to paint an equal number of 2 square feet, simply divide the difference (9 square feet) by the extra square feet Clair paints per hour (2). So, it would take Clair 4.5 more hours to paint an equal amount of mural to Naomi.

Final answer:

Gabe needs to give 25 hours of piano lessons in a month to earn a profit of $326, calculated by setting up an equation that factors in his earnings per hour and the monthly cost of renting the piano.

Explanation:

To find out how many hours of lessons Gabe must give to earn a profit of $326, we need to set up an equation that represents his earnings and costs. Given that Gabe earns $15 per hour giving piano lessons, and his fixed cost for renting the piano is $49 per month, we can create the following equation:

Profit = (Earnings from lessons) - (Cost of renting the piano)

Let h represent the number of hours he teaches. His earnings from giving lessons would be 15h (because he earns $15 for each hour of lessons). The cost of renting the piano is a fixed $49 per month. Therefore, we have:

Profit = (15h) - 49

To make a profit of $326, we substitute this into the equation:

326 = (15h) - 49

Now we solve for h to find out how many hours he needs to teach:

326 + 49 = 15h

375 = 15h

h = 375 / 15

h = 25

Gabe needs to give 25 hours of lessons in a month to earn a profit of $326.

Paula = 6 video games

Myles = 1 video game + Paula(6 video games)

P + M = Total video games

M = 1 + P

P = 6

P + M = 6  + 1 = 7

Final answer:

To find the total number of video games Paula and Myles have, add Paula's 6 games to Myles's 7 games (since he has one more than Paula), which equals 13 games.

Explanation:

To find out how many video games Paula and Myles have in total, we can use a simple addition equation based on the information given. Paula has 6 video games, and Myles has 1 more video game than Paula. Therefore, we can express the number of video games Myles has as 6 games + 1 game, which equals 7 games.

Next, we add the total number of games Paula has to the total number of games Myles has:

Paula's video games: 6 games
Myles's video games: 7 games
Total video games: 6 games + 7 games = 13 games

By adding the two amounts together, we can find the total number of video games they have combined.

Reactive power is 1.152 VARs

Step-by-step explanation:

We are given that in a parallel circuit,[tex]E_{T}=240V[/tex],R=47kΩ and [tex]X_{L}[/tex]=50kΩ.

reactive power means the dissipating power resulting from inductive and capacitive loads measured in volt-amperes reactive(VAR).Since our circuit has inductor only, reactive power will be power dissipated from inductor.

Current through inductor=[tex]\frac{E_{T}}{X_{L}} =\frac{240}{50}=4.8[/tex]milli amps=0.0048 A

Reactive power = (current flowing through inductor)X (Voltage across inductor)

Hence reactive power = 0.0048 X 240=1.152 VARs

Answer: Upper left corner

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

Further Explanation:

The piecewise function is broken down into three parts which I'll refer to as A, B and C (moving down the rows).

Part A is y = -4 but only if x is -3 or smaller. Points on this line include (-3,-4), (-4,-4), (-5,-4), etc. Basically any point where the y value is -4, and the x value is -3 or smaller.

Part B of this piecewise funciton is exactly one point which is (2,0). We plot y = 0 but only when x = 2.

Finally, part C is the horizontal line through y = 3 but we only graph this line if x is larger than 2. Two points on this line are (2,3) and (3,3). The point (2,3) is an open circle because of the fact that x > 2. So x = 2 is not allowed for this piece.

Put this all together, and you get the graph shown in the upper left corner as the final answer.

Note: the bottom left corner is very close to the proper answer, but the presence of an open hole at (-3,-4) is why this is not the actual answer. We are including this point as part of the first piece. This point is included because of the "or equal to" as part of the inequality.

ANSWER 2

Note that point-slope equation is: (y - y₁) = m(x - x₁)

Also note that f(x) = y

Isolate the y. Subtract 7 from both sides:

y + 7 = –(x + 6)

y + 7 (-7) = -(x + 6) - 7

y = -(x + 6) - 7

Note that the equation is really: y = -1(x + 6) - 7

Distribute -1 to all terms within the parenthesis

y = -1(x + 6) - 7

y = -x - 6 - 7

Simplify. Combine like terms

y = -x - 13 ; or f(x) = -x - 13, which is none of the above.

Please check and verify your choices.

To solve the quadratic equation 48x^2 + 44x = 60, one can rearrange it to the standard form, use the quadratic formula, attempt factoring if it is factorable, or multiply by a common factor to simplify. The most common method is the quadratic formula which provides a systematic way to find the solutions.

To solve the equation 48x^2 + 44x = 60, we can use several methods that are commonly used to solve quadratic equations. First, we need to rearrange the equation into the standard quadratic form, which is ax^2 + bx + c = 0. By subtracting 60 from both sides of the equation, we get 48x^2 + 44x - 60 = 0.

One way to solve for x is by using the quadratic formula, which is x = (-b ± √(b^2 - 4ac))/(2a), where a, b, and c are coefficients from the quadratic equation ax^2 + bx + c = 0. In this situation, a = 48, b = 44, and c = -60. By plugging these values into the quadratic formula, we can find the two possible solutions for x.

Alternatively, we can try to factor the quadratic if it can be expressed as a product of two binomials. In some cases, like when the quadratic is a perfect square or can be easily factored, this is a simpler solution. However, if factoring is complicated or not apparent, the quadratic formula can always be used as a reliable method.

Additionally, if the equation has coefficients that are not integers or are difficult to work with, we can multiply both sides by a common factor to simplify the equation into a more manageable form with integer coefficients, after which we can proceed to use the quadratic formula or factor the quadratic, if possible.

The correct expression to find solutions is [tex]\(4(4x + 3)(3x - 5)\)[/tex], as it correctly factors the given quadratic equation.

To find the solutions to the given quadratic equation [tex]\(48x^2 + 44x = 60\)[/tex], we can use factoring. The equation needs to be rearranged to set it equal to zero:

[tex]\[48x^2 + 44x - 60 = 0\][/tex]

Now, we can factor the quadratic expression. The correct factorization is:

[tex]\[4(4x + 3)(3x - 5)\][/tex]

To verify this, distribute the factors:

[tex]\[4(4x + 3)(3x - 5) = 48x^2 + 36x - 60x - 45\][/tex]

Combine like terms:

[tex]\[48x^2 - 24x - 45\][/tex]

This matches the original quadratic expression, confirming the correct factorization.

Therefore, the correct expression that could be used to find the solutions to the given equation is [tex]\(4(4x + 3)(3x - 5)\)[/tex].

Answer:

Average temperature at night -140°C.

Step-by-step explanation:

To find the average temperature at night we have to deduct the drop in temperature from the average temperature at noon.

Average temperature at night = Average temperature at noon - drop in temperature.

                                                  =112°C -  252°C

                                                  = -140°C

The average temperature on the moon's surface at night is -140 degrees Celsius, as calculated by subtracting the temperature drop at night (252 degrees Celsius) from the daytime temperature (112 degrees Celsius).

Your question involves finding out the average temperature on the Moon's surface during the night. The temperature on the Moon at noon is 112 degrees Celsius. However, the temperature drops by 252 degrees Celsius at night. To find the temperature at night, you subtract the drop in temperature from the daytime temperature.

So, let's do the calculation: 112 degrees Celsius (noon temperature) - 252 degrees Celsius (temperature drop) = -140 degrees Celsius. Therefore, the average temperature on the Moon's surface during the night is -140 degrees Celsius.
