If the total amount given the original price and tax or tip are 123.28,7. 5%, the total amount including tax is $132.52.

To find the total amount given the original price and tax or tip, we need to add the amount of tax or tip to the original price.

In this case, the original price is $123.28 and the tax is 7.5%. To find the amount of tax, we can multiply the original price by the tax rate expressed as a decimal.

Tax = 0.075 x $123.28 = $9.24

Therefore, the amount of tax is $9.24. To find the total amount, we simply add the original price and the amount of tax:

Total amount = $123.28 + $9.24 = $132.52

Note that if the 7.5% was a tip instead of a tax, we would calculate it in the same way by multiplying the original price by the tip rate expressed as a decimal.

a) The probability of a randomly selected diner waits less than 8 minutes for a table is 0.4

b) The probability of a randomly selected diner waits more than 1.5 minutes is 0.925

Given, wait times of between 0 and 20 minutes at a local restaurant follow a uniform distribution.

The probability density function of a uniform distribution is given by

f(x) = {1/(b-a)} where a ≤ x ≤ b

where a = 0 and b = 20

Therefore, the probability density function of f(x) = 1/20 for 0 ≤ x ≤ 20

For the  probability that a randomly selected diner waits between 2 and 7.5 minutes for a table, we need to find the area under the curve from x = 2 to x = 7.5

∴ P(2 ≤ x ≤ 7.5) = ∫₂⁷.⁵(1/20) dx

= 5.5/20 ⇒ 0.275

a) We need to find the area under the curve from x = 0 to x = 8

∴ P(x < 8) = ∫₀⁸(1/20) dx

= 8/20 ⇒ 0.4

b) We need to find the area under the curve from x = 1.5 to x = 20

Using the definition of a straight angle, the measure of angle MON is calculated as: 130°.

A straight angle is an angle that measures exactly 180 degrees. It is a flat angle, which means it has no curvature and looks like a straight line.

Therefore, we have:

m∠LOM + m∠MON = 180 [straight angle is equal to 180 degrees]

Substitute:

4x + 30 + 8x + 90 = 180

Solve for x:

12x + 120 = 180

12x = 180 - 120

Answer:

120 ft

Step-by-step explanation:

Let's assume that the length of the field is x feet. Then, according to the problem statement, the width of the field is (x - 20) feet.

The area of a rectangle is given by the formula A = length x width. So, we can write:

x(x - 20) = 12,000

Expanding the left-hand side, we get:

x^2 - 20x = 12,000

Bringing all the terms to one side, we have:

x^2 - 20x - 12,000 = 0

Now, we can solve this quadratic equation using the quadratic formula:

x = (-(-20) ± sqrt((-20)^2 - 4(1)(-12,000))) / (2(1))

x = (20 ± sqrt(20^2 + 48,000)) / 2

x = (20 ± 220) / 2

We discard the negative root, since a length cannot be negative, and we get:

x = 120

Therefore, the length of the field is 120 feet.

Answer:

Let's use variables to represent the number of kittens each person has fostered.

Let x be the number of kittens Kim has fostered.

Then, according to the problem, Preston has fostered one less than one third as many kittens as Kim, so Preston has fostered:

(1/3)x - 1

We know that the total number of kittens fostered is 47. Therefore, we can write an equation:

x + (1/3)x - 1 = 47

Simplifying and solving for x:

(4/3)x = 48

x = 36

So Kim has fostered 36 kittens.

To find out how many kittens Preston has fostered, we can substitute x = 36 into the expression we found earlier:

(1/3)x - 1 = (1/3)(36) - 1 = 11

Therefore, Preston has fostered 11 kittens.

In summary, Kim has fostered 36 kittens and Preston has fostered 11 kittens.

Answer:

36, 11

Step-by-step explanation:

Preston and Kim 47 kittens

Kim has fostered X number of kittens

Preston has fostered X/3 - 1 ( 1/3 of Kim - 1)

Total number of kitten will be Preston +Kim

X +1/3X - 1 = 47

Add 1 to both sides

X + 1/3X = 48

If 4/3X is 48, X is 36

If Kim has 36kittens, Preston fostered 47- 36 =11

To check

1/3 of 36 = 12

Subract 1 = 11

To convert the total time from seconds to minutes, we need to divide by 60. So, the total time in minutes would be: (720 + 420) / 60 = 1140 / 60 = 19 minutes.

To find the total time it takes Andrew to take a shower and eat breakfast, we need to add the time it takes for each activity. Andrew takes 720 seconds to take a shower and 420 seconds to eat breakfast. To convert seconds to minutes, we divide the total time in seconds by 60. So the total time it takes Andrew to take a shower and eat breakfast is (720 + 420) / 60 = 19 minutes. Therefore, it takes Andrew 19 minutes to take a shower and eat breakfast.

Since, that the total interest that will be paid on a 40-year mortgage from a home loan of $100,000 is going to be $480,000. Then,  the payments each month if the payments are to pay off both the loan and the interest will be $1,504.

The 40-year loan has the lowest monthly payment at $1,504. But that only means "saving" $183 per month on the 30-year loan. When considering the total price of the house in this example, adding an additional 10 years to the term of the loan seems overkill, reducing the monthly payment by less than $200.

A 40-year loan doesn't sound like a good deal. But for homeowners struggling to meet their monthly payments and get a 40-year loan modification, the lower payments could have a big impact.

Comparing the 30-year and 15-year numbers is even more extreme. The monthly payment on the 15-year loan is an additional $700. Some buyers can afford higher payments. The advantage of the 15-year loan is that the total interest paid on the loan is $103,218, compared to $289,970 for the 30-year loan. Fifteen years seems to pass so quickly, and it's an exciting feeling to stop paying.

Objections to the 15-year loan could include a missed opportunity. With an interest rate of 4.67% on the 30-year loan, one can expect a higher rate of return in the long run by investing heavily in the stock market. But that raises the question of whether the $700 a month in cash freed up by the 30-year loan will be invested. It might be tempting to spend that money on a more expensive car than the one you would otherwise have purchased.

A family's needs, including space, savings and investment for retirement and education, as well as many household expenses should be considered when deciding which home to buy and the term of the loan. At a minimum, homebuyers need to understand how the different types of loans work.

Answer:

To find the extreme value of the function f(x) = 6x^2 - 180x + 1000, we can first take the derivative of the function and set it equal to zero:

f'(x) = 12x - 180 = 0

Solving for x, we get x = 15. Substituting this value back into the original function, we get:

f(15) = 6(15)^2 - 180(15) + 1000 = 1250

So the extreme value of the function is 1250, which represents the maximum profit in thousands of dollars that can be earned by selling a certain number of items.

More specifically, the value x = 15 is the value of x that maximizes the profit, and the maximum profit is $1,250,000. This means that if the company sells 15 items, they will make the most profit possible.

To solve this equation, we need to consider two cases, one where 2x + 1 is positive and another where it is negative. We will then solve for x in each case and check our solutions to make sure they satisfy the original equation.

Case 1: 2x + 1 ≥ 0

In this case, we have:

|2x + 1| = 2x + 1

and

|3x - 11| = 3x - 11

Substituting these expressions into the original equation, we get:

2x + 1 = 3x - 11

Solving for x, we get:

x = 12

Checking our solution, we have:

|2x + 1| = |2(12) + 1| = 25

and

|3x - 11| = |3(12) - 11| = 25

Therefore, x = 12 is a valid solution to the equation.

Case 2: 2x + 1 < 0

In this case, we have:

|2x + 1| = -(2x + 1) = -2x - 1

and

|3x - 11| = -(3x - 11) = -3x + 11

Substituting these expressions into the original equation, we get:

-2x - 1 = -3x + 11

Solving for x, we get:

x = -10

Checking our solution, we have:

|2x + 1| = |2(-10) + 1| = 21

and

|3x - 11| = |3(-10) - 11| = 41

Therefore, x = -10 is not a valid solution to the equation.

Therefore, the only solution to the equation |2x + 1| = |3x - 11| is x = 12.

To solve this problem, we can use the formula for exponential growth:

N = N0 * (1 + r)^t

Where:

N0 = the initial population size

N = the population size after t time periods

r = the growth rate per time period

t = the number of time periods

In this case, we know that the initial population (N0) is 6000, the growth rate (r) is 15% per day, and we want to find the population size (N) after 10 days (t = 10).

First, we need to convert the growth rate from a percentage to a decimal:

r = 15% / 100% = 0.15

Now we can plug in the values and solve for N:

N = 6000 * (1 + 0.15)^10

N = 6000 * 3.439

N ≈ 20,634

Therefore, the population of bacteria after 10 days would be approximately 20,634.

One bottle of liquid plant food is enough for at least 12 weeks, and potentially a bit more.

William uses 40 milliliters of liquid plant food per week, so to find out how much plant food he needs for 12 weeks, we can simply multiply the weekly usage by the number of weeks:

Amount of plant food needed for 12 weeks = 40 milliliters/week x 12 weeks = 480 milliliters

So, William needs 480 milliliters of liquid plant food for 12 weeks.

Since the bottle of liquid plant food, William purchased contains 0.5 liters or 500 milliliters of liquid plant food, we can see that one bottle is enough for 12 weeks since 480 milliliters is less than the total amount of liquid plant food in the bottle.

In fact, we can calculate how many weeks one bottle of liquid plant food will last William by dividing the total amount of liquid plant food in the bottle by the amount used per week:

Time to use up the liquid plant food = (Total amount of liquid plant food) / (Amount used per week) = 500 ml / 40 ml/week ≈ 12.5 weeks

Step-by-step explanation:

If E is the midpoint of DF then the x-distance between D and E must be the same as that between E and F and similarly for the y-distance

In addition, the x, y coordinates of D must be less than the x, y coordinates for E

x-distance from E to F = 5- 4 = 1

x-distance from D to E = 1 so x-coordinate of D = 4 - 1 = 3

y-distance from E to F = 8 - 3 =  5

y-distance from D to E = 3 - 5 = -2

So coordinate of D is(3, -2)

We can use this fact to draw diagonal BD and label its length as x:

[tex]$\begin{align*}AB &= DC \AD + DB &= BC + DB \AD &= BC\end{align*}[/tex]

Therefore, we can conclude that:

[tex]$\begin{align*}AD &= BC\end{align*}[/tex]

Thus, the length of AD is equal to the length of BC.

Answer: The function y = 7(2/3)^x is an example of exponential decay.

This is because the base of the exponential function, 2/3, is between 0 and 1, which means that the function is decreasing as x increases. As x increases, the value of (2/3)^x becomes smaller and smaller, which causes the overall value of the function y to decrease over time.

Exponential decay is a type of exponential function where the value of the function decreases over time. In contrast, exponential growth is a type of exponential function where the value of the function increases over time, and the base of the function is greater than 1.

Step-by-step explanation:

The equation represents the amount of money, in dollars, Kenny will save in x weeks is y = $10*x

We know that Kenny saved 10 dollars every week.

Then, if we define the variable y as the savings, after one week we know that:

y = 10

After another week:

y = 20

And so on.

We can define x as the number of weeks, and now we know that after x weeks, the amount of money that Kenny has saved is x times $10, this gives the linear equation.

y = $10*x

That is the equation we wanted.
