Answer: 11/20

Step-by-step explanation: you take the original 60 cookies and take away the 12 and the 15 to get 33. The original whole number was 60/60. Now it would be 33/60, but in simplest form it is 11/20.

The number of watts which is the power of the turbine for each case is respectively; 600 W; 506.25 W; 300 W

We are given;

Density of air; ρ = 1.2 kg/m³

Area; A = r² with r being the blade length

Formula for power in turbine is;

P = ¹/₂ρAv³

1) v = 10 m/s and r = 1 m.

Thus;

P = ¹/₂ * 1.2 * 1² * 10³

P = 600 W

2) v = 15 m/s and r = 0.5 m.

Thus;

Power = ¹/₂ * 1.2 * 0.5² * 15³

P = 506.25 W

3) v = 20 m/s and r = 0.25 m.

Thus;

Power = ¹/₂ * 1.2 * 0.25² * 20³

P = 300 W

Answer:

n = (s + 360)/ 180

Step-by-step explanation:

180(n - 2)= s ? ummm ill try...

180n - 360 = s

180n = s + 360

n = (s + 360)/ 180

Answer:

n = s/180 +2

Step-by-step explanation:

180 (n-2) = s

Step 1: To find n, we need to get rid of 180 from the left side of the equation. Divide 180 by both sides; then we can cross out 180 with itself on the left, leaving (n-2)

180 (n-2) /180 = s/180

Step 2: Now we got rid of 180 on the left, we must isolate n. To do that, we must bring -2 to the other side of the equation. There, it would become positive, and n gets isolated.

n = s/180 + 2

Although, you may or may not be confused with my answer, and I realized that there's two ways to solve this. Let me show you:

Step 1: 180(n-2) = s

Distribute - multiply 180 with every term in the brackets, which then we would end up with:

180n-360 = s

Step 3: Bring -360 to the right side of the equation, where it would become positive.

180n = s+360

Step 4: To isolate n, divide 180 by both sides of the equation:

180n/180 = s+360/180

Step 4: Now you have:

n = s+360/180.

Though you could leave your answer as the one above, you should simplify it.

Step 5: n = s/180 + 360/180

360/180 = 2, therefore the simplified answer is:

n = s/180 +2

The function v(t) is a composite function of the stock functions f(t) and g(t)

The functions are given as:

f(t) = 12(1.20)^t

g(t) = -4.5t

When both functions are added, we have:

v(t) = 12(1.20)^t - 4.5t

See attachment for the graph of the function v(t)

This is the point where t = 0

From the graph of the function, the initial value is 12

This is the point where t = 8

From the graph of the function, the final value at the end of the day is 15.598

From the graph, we can see that the stock value decreases to a minimum and then increases.

From the graph, we can see that the stock value is at t = 3.955

This means that the stock is at the lowest after about 4 hours

Step-by-step explanation:

Since you need it quick, no explanation for now.

Answer:

Length of the garden: 95 m

Width of the window: 86 cm

Step-by-step explanation:

Part A:

We can use the equation for area to find the length of the garden.

[tex]Area = Width * Length[/tex]

If we simply divide both sides of the equation by width, we will be solving for lenght:

[tex]\frac{Area}{Width} = Length[/tex]

Now, plug in the known values for the area and width of the garden:

[tex]\frac{6460}{68}=Length[/tex]

[tex]95=Length[/tex]

Part B:

This time, we'll have to use the equation for perimeter:

[tex]Perimeter = [2(Width)]+[2(Length)][/tex]

Because we want to know the width, and already know the perimeter and length we can once again use algebra to solve for the width:

[tex]Perimeter-[2(Length)] = 2(Width)\\\frac{Perimeter-[2(Length)]}{2} =Width[/tex]

Now, simply plug in the values for the perimeter and the length and solve:

[tex]\frac{370-[2(99)]}{2} =Width\\\\\frac{370-198}{2} =Width\\\\\frac{172}{2}=Width\\\\86=Width[/tex]

Therefore, the width of the window is 86 cm.

The vertices of the square are the coordinates of the endpoints

The third vertex of the square could be (0,7) or (-5,1)

Two vertices of the square are:

(0,-3) and (4,2)

Calculate the distance between these vertices using:

[tex]d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]

Square both sides

[tex]d^2 = (x_2 - x_1)^2+(y_2 - y_1)^2[/tex]

The above expression represents the area of the square.

So, we have:

[tex](x_2 - x_1)^2+(y_2 - y_1)^2 = 41[/tex]

Next, we test the options with the given vertices (0,-3) and (4,2)

So, we have:

A. (0,7)

[tex](0 - 0)^2+(7 + 3)^2 = 41[/tex]

[tex]100 \ne 41[/tex]

[tex](0 - 4)^2+(7 - 2)^2 = 41[/tex]

[tex]41 = 41[/tex]

B. (-5,1)

[tex](-5 - 0)^2+(1 + 3)^2 = 41[/tex]

[tex]41 = 41[/tex]

[tex](-5 - 4)^2+(1 -2)^2 = 41[/tex]

[tex]82 \ne 41[/tex]

C.(5,13)

[tex](5 - 0)^2+(13 + 3)^2 = 41[/tex]

[tex]281 \ne 41[/tex]

[tex](5 - 4)^2+(13 -2)^2 = 41[/tex]

[tex]122 \ne 41[/tex]

D.(-2,-2)

[tex](-2 - 0)^2+(-2 + 3)^2 = 41[/tex]

[tex]5 \ne 41[/tex]

[tex](-2 - 4)^2+(-2 -2)^2 = 41[/tex]

[tex]52 \ne 41[/tex]

E.(4,-6)

[tex](4 - 0)^2+(-6 + 3)^2 = 41[/tex]

[tex](4 - 4)^2+(-6 -2)^2 = 41[/tex]

Step-by-step explanation:

In addition to the fact that she has never kept a diary before, Anne Frank finds it strange that someone like her would do so. She also believes that neither she nor anybody else would find interest in a diary kept by a thirteen-year-old schoolgirl.

The residents are given five minutes to gather their belongings when the military break down the annex door. Nothing else may be taken by them. The scene comes to a close as Anne's voice commands Miep to keep her diary secure.

Frank discussed how people saw her in her final journal post, calling herself "a tangle of paradoxes." "As I've told you many times, I'm torn in two," she wrote. One half of myself is full of excitement, exuberance, flippancy, and, most importantly, the capacity to see the lighter side of things.
