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:

15

Step-by-step explanation:

All you have to do is plug in the values into the variables.

[tex](-2)^{4} - (-1)^{\frac{2}{5} }[/tex]

Now evaluate.

[tex](-2)^{4} = 16[/tex]

[tex](-1)^{\frac{2}{5} } = 1[/tex]

Now subtract the two numbers.

16 - 1 = 15

The answer is 15.

ED2020

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

Therefore, the correct option is D).

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

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.

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

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:

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.
