The number of tickets sold to students by Sam will be 14.

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Sam and Chad are ticket-sellers at their class play. Sam is selling student tickets for $2.00 each, and Chad selling adult tickets for $5.50 each. if their total income for 24 tickets was $83.00.

Let x be the number of tickets sold to students and y be the number of tickets sold to adults. Then the equation is given as,

x + y = 24               ...1

2x + 5.5y = 83       ...2

From equations 1 and 2, then we have

2(24 - y) + 5.5y = 83

48 - 2y + 5.5y = 83

3.5y = 35

y = 10

Then the value of x will be given as,

x + 10 = 24

x = 24 - 10

x = 14

The number of tickets sold to students by Sam will be 14.

To find the initial number of chocolates Jenny had, we solve the equation (x - 2)/2 = 6, which results in x = 14. Therefore, Jenny had 14 chocolates initially.

The question asks to determine how many chocolates Jenny had in the beginning if she eats two and gives half of the remainder to Lisa, who ends up with six chocolates. To solve this, we let x represent the initial number of chocolates Jenny had. After eating two chocolates, Jenny has x - 2 left. She gives half of this remainder to Lisa, which means Lisa receives (x - 2)/2 chocolates. Since Lisa has six chocolates, we set up the equation (x - 2)/2 = 6. Solving this gives us x - 2 = 12 and therefore, x = 14. Hence, Jenny had 14 chocolates in the beginning. The correct answer is option C. 14.

Answer:

A. The ball is at the same height as the building between 8 and 10 seconds after it is thrown.

C. The ball reaches its maximum height about 4 seconds after it is thrown

Step-by-step explanation:    • The ball is at the same height as the building between 8 and 10 seconds after it is thrown. TRUE - the height is zero somewhere in that interval, hence the ball is the same height from which it was thrown, the height of the roof of the building.

• The height of the ball decreases and then increases. FALSE - at t=2, the height is greater than at t=0.

• The ball reaches its maximum height about 4 seconds after it is thrown. TRUE - the largest number in the table corresponds to t=4.

• The ball hits the ground between 8 and 10 seconds after it is thrown. FALSE - see statement 1.

• The height of the building is 81.6 meters. FALSE - the maximum height above the building is 81.6 meters. Since the ball continues its travel to a distance 225.6 meters below the roof of the building, the building is at least that high.

The length of AM is:

                                21 units.

Point M is the midpoint of AB.

AM= 3x+3, and AB=8x−6

Since, the midpoint divides the line segment into two equal parts i.e. it bisects the line segment.

Hence, we have:

                         AM+MB=AB

Also, AM=MB

Hence, we have:

     [tex]3x+3+3x+3=8x-6[/tex]

on combining the like terms in the left hand side of the equation we have:

[tex]3x+3x+3+3=8x-6\\\\6x+6=8x-6[/tex]

Now, on subtracting both side of the equation by 6x we have:

[tex]6=8x-6-6x\\\\6=8x-6x-6\\\\6=2x-6[/tex]

on adding 6 on both side of the equation we have:

[tex]6+6=2x\\\\12=2x\\\\2x=12\\\\x=\dfrac{12}{2}\\\\x=6[/tex]

Hence, we have:

[tex]AM=3\times 6+3\\\\AM=21\ \text{units}[/tex]

a. Probability density function (pdf) of X: 0.247 for 0.20 < x < 4.25.

b. Probability that diameter exceeds 2 mm: 0.556.

c. Probability that diameter is within 2 mm of the mean diameter: 0.988.

(a) Probability density function (pdf) of X:

For a uniform distribution with A = 0.20 and B = 4.25, the pdf is constant within the range A to B and 0 elsewhere. Therefore:

f(x) = 1 / (B - A) = 1 / (4.25 - 0.20) = 1 / 4.05 ≈ 0.247 for 0.20 < x < 4.25

(b) Probability that diameter exceeds 2 mm:

P(X > 2) = (4.25 - 2) * f(x) = 2.25 * 0.247 ≈ 0.556

(c) Probability that diameter is within 2 mm of the mean diameter:

The mean of a uniform distribution is (A + B)/2 = (0.20 + 4.25)/2 = 2.225.

So, we need to find P(2.225 - 2 < X < 2.225 + 2), which is P(0.225 < X < 4.225).

P(0.225 < X < 4.225) = (4.225 - 0.225) * f(x) = 4 * 0.247 ≈ 0.988

To find the cost of the love seat, couch, and chair, set up a system of equations and solve for the variables.

To find the cost of the love seat, the couch, and the chair, we need to set up a system of equations based on the given information. Let's represent the cost of the chair as x. Since the couch costs twice as much as the chair, its cost will be 2x. The love seat costs $400 more than the couch, so its cost will be 2x + $400. The sum of the costs of all three pieces of furniture is $1565. Using these equations, we can solve for x, and then find the costs of the love seat, the couch, and the chair.

Equations:

Cost of the Chair: $233

Cost of the Couch: 2x = 2($233) = $466

Cost of the Love Seat: 2x + $400 = 2($233) + $400 = $466 + $400 = $866

Answer:

The required equation is [tex]C=\frac{5}{9}(F-32)[/tex]

Step-by-step explanation:

Consider the provided equation.  

[tex]F= \frac{9}{5}C+32[/tex]

Solve the formula for C.

Subtract 32 from both sides.

[tex]F-32= \frac{9}{5}C+32-32[/tex]

[tex]F-32= \frac{9}{5}C[/tex]

Multiply both the sides by 5/9.

[tex]\frac{5}{9}(F-32)= \frac{9}{5}C\times \frac{5}{9}[/tex]

[tex]C=\frac{5}{9}(F-32)[/tex]

Hence the required equation is [tex]C=\frac{5}{9}(F-32)[/tex]

The formula to convert Fahrenheit to Celsius is C = 5/9( F - 32 ).

Given the equation in the question:

F = (9/5)C + 32

To solve for C (Celsius) in the conversion formula F = (9/5)C + 32, first, isolate the terms that contain C on one side of the equation.

F = (9/5)C + 32

Subtract 32 from both sides of the equation:

F - 32 = (9/5)C + 32 - 32

F - 32 = (9/5)C

Next, multiply both sides by the reciprocal of the coefficient of C: 5/9:

5/9( F - 32 ) = 5/9 × (9/5)C

5/9( F - 32 ) = C

C = 5/9( F - 32 )

Therefore, C equals C = 5/9( F - 32 ).

The amount of water flowing each second is:

rate = 5.2 x 10^5 gallons / second

Since we know that:

1 hour = 3600 seconds

Therefore:

rate = (5.2 x 10^5 gallons / second) * (3600 seconds / hour)

rate = 1.872 x 10^9 gallons / hour

Final answer:

The average volume of water that flows over the falls in an hour is 1.89 x 10^9 gallons/hour.

Explanation:

To calculate the amount of water that flows over the falls in an hour, we need to convert the given flow rate from gallons per second to gallons per hour.

There are 3600 seconds in an hour, so we can multiply the flow rate (5.25 x 105 gallons per second) by 3600 to find the flow rate in gallons per hour.

The calculation would be: 5.25 x 105 gallons/s * 3600s/hour = 1.89 x 109 gallons/hour.

The result, in scientific notation, is 1.89 x 109 gallons/hour.

Final answer:

The two-digit number where the tens digit is three more than the units digit and the number is seven times the sum of its digits is 74.

Explanation:

The question involves finding a two-digit number that fits two conditions: it is seven times the sum of its digits, and its tens digit is three more than the units digit. To solve this, we set up the following equations. Let x represent the tens digit and y represent the units digit.

Substituting x from the second equation into the first equation, we get 10(y + 3) + y = 7(y + 3 + y). Solving this, we find y = 4 and therefore x = 4 + 3, which gives x = 7. Thus, the number is 74.
