The volumes of two similar solids are 729 m^3 and 125m^3. The surface area of a larger solid is 324 m^3. What is the surface area of the smaller solid

Answer:

Domain exists on all real values and it is expressed according to the notation:

(-∞, ∞)

Step-by-step explanation:

The domain of a function is the values of the input variables x that will make the function exist.

Given the function f(x)=-16x^2+400

Since the variable x is a perfect square, this means that the function f(x) will exists for all values of x. The domain is expressed as:

(-∞, ∞)

Answer:

The answer is C

Answer:

The equation that relates temperature to depth is y = 28 - 0.065·x

Step-by-step explanation:

Los parámetros dados son;

La temperatura del agua en la superficie = 28 ° C

La temperatura del agua a 200 m por debajo de la superficie = 15 ° C

Dado que la relación es lineal, tenemos;

Sea la pendiente de la relación = m, por lo tanto;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Dónde;

x₁ = 0 m, y₁ = 28 ° C, x₂ = 200 m, y₂ = 15 ° C, tenemos;

[tex]Slope, \, m = \dfrac{15^{\circ}C-28^{\circ}C}{200 \, m-0 \, m} = \dfrac{(-13)^{\circ}C}{200 \, m} = -0.065 ^{\circ}C/m[/tex]

Por lo tanto, la ecuación en forma de pendiente puntual se convierte en;

y - 28 = -0,065 × (x - 0)

y = -0.065 · x + 28 = 28 - 0.065 · x

Por lo tanto, la ecuación que relaciona la temperatura con la profundidad es y = 28 - 0.065 · x.

The net profit of Wayne be when he sells the building is $606000 and this can be determined by using the formula of profit.

Given :

First, determine the annual revenue which is given by:

Annual Revenue = Monthly Rent [tex]\times[/tex] Number of Rooms [tex]\times[/tex] Number of months [tex]\times[/tex] Three-quarters

Annual Revenue = 495 [tex]\times[/tex] 20 [tex]\times[/tex] 12 [tex]\times[/tex] (3/4) = $89100

Total Profit = (Annual Revenue - Annual Cost) [tex]\times[/tex] (Number of years)

                  = (89100 - 26400) [tex]\times[/tex] 15

                  = $940500

Now, the net profit of Wayne when he sells the building is given by:

Net Profit = Value of the building at the end of the 15th year + Total profit from renting - Cost of the building

Net Profit = 424490.38 + 940500 - 759000 = 605990.38

Net Profit [tex]\approx[/tex] $606000

Answer:

12 hours

Step-by-step explanation:

Let's say that our variable is x, where x equals the amount of hours.

You have an upright price of $500 for the first company, as well as an additional $20 an hour.

The second company has an upright price of $620, and charges $10 an hour.

f(x)= 20x+500

g(x)= 10x+620

You want to find how many hours must be worked for the two companies to charge the same amount.

You want to find how many miles it takes to make the two equations equal:

20x+500=10x+620 (Set them equal to each other because you are trying to find when the hours are equal and the cost is equal)

10x+500=620 (Subtract 10x from both sides)

10x=120 (Subtract 500 from both sides)

x=12 (Divide both sides by 10)

Remember that x is the amount of hours, so, the companies would charge the same if they worked for 12 hours.

If Marie rents it for 12 months it'll be 12x34= $408.

If Marie buys a trombone it'll cost her 495 which is more expensive.

Answer:

Buy

Step-by-step explanation:

If it is truly your dream car and you want to keep it for many years to come without an exact amount of time then the best option would be to buy the car, assuming that you have the necessary cash to do so. Leasing a car means you would have to pay a monthly amount every single month, this amount quickly adds up and can become more than what the car is actually worth. Also, regardless of how many payments are made, once you stop making payments you would need to return the car. The car is never going to be owned by you by leasing. If you buy the car, once you decide you no longer want it, it is still yours to do as you wish. This includes selling it.

Answer:

  x  = -12

Step-by-step explanation:

Given expression:

        -45 = 5(x + 3)

the solution of an algebraic expression is the value(s) that makes the expression true.

 In this problem, let us solve for x;

                -45 = 5(x + 3)  

   Applying the distributive property on the right hand side;

                -45  = 5x + 15

  Now, add (-15) to both sides of the expression;

               -45 + (-15) = 5x + 15 + (-15)

                -45 - 15  = 5x

                    -60    = 5x

Then  divide both sides by 5;

                x  = -12

Answer:

d. x = 16

Step-by-step explanation:

From the alternate interior angle theorem, we can see that the sum of the 2 labeled angles is 180. We can therefore set up an equation and solve for x:

7x + (2x + 36) = 180

9x + 36 = 180

9x = 144

x = 16

Therefore, x = 16.

Complete question is;

In addition to his hourly wage, albert earns bonus when the amount of money collected is greater than the cost to print the total number of programs he sold. His bonus is equal to 1/2 of the difference between the amount of money collected M(x) = 2.50x and the cost c(x) = 0.5x + 40

How much does Albert earn as bonus when he sells 309 baseball programs?

Answer:

Bonus earned for selling 309 baseball programs = $289

Step-by-step explanation:

We are given formula for amount collected as;M(x) = 2.50x

Now, if he sells 309 baseball programs, it means, amount collected is;

M(309) = 2.5(309) = $772.5

We are told cost formula is;

c(x) = 0.5x + 40

Thus;

c(309) = 0.5(309) + 40

c(309) = $194.5

We are told that his bonus is when the amount of money collected is greater than the cost to print the total number of programs he sold.

Thus;

Bonus = $772.5 - $194.5

Bonus = $578

We are told he earns ½ of the bonus.

Thus, he earns ; ½ × 578 = $289

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

The the age of Sarah be x and the amount she has be y:

When Sarah was 5 and her amount is $50

When x1 = 5, y1 = $50

Also when Sarah was 6, her amount is $100

When x2 = 6, y2 = $100

Find the slope which is also the constant of proportionality

x= ky

k = y2-y1/x2-x1

k = 100-50/6-5

k = 50/1

k = 50

Substitute the value of k in the formula:

x = 50y

This means that Sarah's age is directly proportional to the amount she have. Hence, it can be concluded that it is a direct relationship

Answer:

X=22

Step-by-step explanation:

Step 1: Subtract 3.5x from both sides.

2.5x+18−3.5x=3.5x−4−3.5x

−x+18=−4

Step 2: Subtract 18 from both sides.

−x+18−18=−4−18

−x=−22

Step 3: Divide both sides by -1.

−x/-2 = -22/-1

x=22

The value of x in the given equation is 22

The given equation;

2.5x + 18 = 3.5x - 4

To find:

The equation is simplified as follows;

2.5x + 18 = 3.5x - 4

collect similar terms together

2.5x - 3.5x = - 4 - 18

- x = - 22

x = 22

Thus, the value of x in the given equation is 22
