Answer:

[tex]x=\dfrac{y}{0.62}[/tex]

Step-by-step explanation:

[tex]5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{3.1}{5}=0.62\ \text{miles}[/tex]

[tex]10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{6.2}{10}=0.62\ \text{miles}[/tex]

Let [tex]y[/tex] be the distance in miles. So distance in km is given by

[tex]x=\dfrac{y}{0.62}[/tex].

The equation that shows the approximate distance in kilometers as a function if the distance in miles is [tex]x=\dfrac{y}{0.62}[/tex].

Step-by-step explanation:

900(1.03)^t = 1200

(1.03)^t= 1.33

( 1.03)^t= ( 1.03)^9

So, t= 9

Answer:

∠ B = 123°, ∠ D = 57°

Step-by-step explanation:

Each lower base angle is supplementary to the upper base angle on the same side.

∠ A and ∠ D are on the same side, then

6x + 12 + 2x + 20 = 180

8x + 32 = 180 ( subtract 32 from both sides )

8x = 148 ( divide both sides by 8 )

x = 18.5

Thus

∠ A = 6x + 12 = 6(18.5) + 12 = 111 + 12 = 123°

∠ D = 2x + 20 = 2(18.5) + 20 = 37 + 20 = 57°

The lower base angles and the upper base angles are congruent, so

∠ B = ∠ A = 123°

∠ C = ∠ D = 57°

Answer:

Step-by-step explanation:

#1). It could be good to provide us with the picture, because the answer depends from the angle we choose for letter A.

--- If angle A is acute, then m∠A = m∠D

and

6x + 12 = 2x + 20 ⇒ x = 2

m∠A = m∠D = 24°

m∠B = m∠C = 180° - 24° = 156°

--- If angle A is obtuse, then m∠A + m∠D = 180°

and

6x + 12 + 2x + 20 = 180 ⇒ x = 18.5

m∠A = m∠B = 6(18.5) + 12 = 123°

m∠D = m∠C = 2(18.5) + 20 = 57°

#2). 12k + 5 = 145

12k = 140

Answer:

4000 cm^3

Step-by-step explanation:

Note that no image was attached for reference purposes

Step one:

We are given that the original length and width of the cube is 20cm

if the cut part is 10cm

hence the dimension of the cut part is

lenght = 20cm

Width= 20cm

Hieght= 10cm

Step two:

the volume of the cut part will be

Volume= 20*20*10

Volume= 4000 cm^3

Given:

[tex]R^2=0.92,a=8000,b=0.9[/tex].

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]

To find:

The exponential regression representing the population of Lazy Town as a function of time in years.

Solution:

We have, [tex]a=8000,b=0.9[/tex].

Exponential regression model is

[tex]y_1\sim a(b)^{x_1}[/tex]        ...(i)

Putting [tex]a=8000[/tex] and [tex]b=0.9[/tex] in (i), we get.

[tex]y_1\sim 8000(0.9)^{x_1}[/tex]

Thus, [tex]y_1\sim 8000(0.9)^{x_1}[/tex] is the required exponential regression representing the population of Lazy Town as a function of time in years.

Answer:

Yes

Step-by-step explanation:

Yes. 72 divided by 4 would be 18, so it is a factor

Answer:

Yes

Step-by-step explanation:

Yes because 4 x 18 = 72

72 divided by 18 = 4

I know this because if you multiply 4 x 18 you will get 72. To check you can do the inverse operation, which is division, so with that being said,  72 divided by 18 = 4.

I explained to so you can have a better understanding. Have a great day!

Answer:

The equation of the graphed line is:

Step-by-step explanation:

From the graph, it is clear that the line is a horizontal line at y = 2.

We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.

In other words, the equation of the horizontal line would always get the form:

y = k

where k is the y-intercept of the line.

Determining the y-intercept of the line:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept k = 2

Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation

y = 2

Therefore, the equation of the graphed line is:
