Step-by-step explanation:

draw a triangle then label corners a and b. spread them 120 degrees apart and there you have it.

The vectors orthogonal to v = (5, 0, 0) are of the form w = (0, y, z), where y and z can be any real numbers. An orthogonal basis for R^3 that includes v is {v, u, w} = {(5, 0, 0), (0, 1, 0), (0, 0, 1)}.

The dot product of v and w is given by  v · w = 5x + 0y + 0z = 5x. For v · w to be zero, we set 5x = 0, which implies x = 0. Therefore, any vector w = (0, y, z), where y and z can be any real numbers, will be orthogonal to v. To find an orthogonal basis for R^3 that includes v, we can choose two additional vectors, let's call them u and w, such that they are orthogonal to v and also orthogonal to each other.

Let's choose u = (0, 1, 0) and w = (0, 0, 1). These vectors are orthogonal to v since their dot product with v is zero: v · u = 5(0) + 0(1) + 0(0) = 0 v · w = 5(0) + 0(0) + 0(1) = 0. Furthermore, u and w are orthogonal to each other: u · w = 0(0) + 1(0) + 0(1) = 0. Hence, the vectors {v, u, w} = {(5, 0, 0), (0, 1, 0), (0, 0, 1)} form an orthogonal basis for R^3 that includes v.

Answer:

Part 1: 359,007 ft³

Part 2: 216 times smaller

Part 3: 21600%

Step-by-step explanation:

Part 1:

The parameters for the tank are;

The radius of the tank = 70 feet

The volume of a sphere = 4/3·π·r³

Therefore, the volume of a quarter sphere = 1/4×The volume of a sphere

The volume of a quarter sphere = 1/4×4/3·π·r³ = π·r³/3

Plugging in the value for the radius gives

Volume = π×70³/3 = 114,333.33×3.14 = 359,006.7≈ 359,007 ft³.

Part 2:

The dimension of the scale model  = 1/6 × Actual dimension

Therefore, we have the radius of the sphere of the scale model = 1/6 × 70

Which gives;

The radius of the sphere of the scale model = 35/3 = 11.67 feet

The volume of the scale model = π·r³/3 = (3.14×11.67³)/3 = 1662.07 ≈ 1662 ft³

The number of times smaller the scale model is than the actual volume = (Actual volume)/(Scale model) = (359,007 ft³)/(1662 ft³) = 216 times

The number of times smaller the scale model is than the actual volume =  216 times = (1/Scale of model)³ = (1/(1/6))³ = 6³.

Part 3:

The percentage of the mock-up, x, to the volume of the actual tank is given as follows

x/100 ×  1662  = 359,007

∴ x = 216 × 100 = 21600%

The percentage of the mock-up, to the volume of the actual tank is 21600%.

Answer:

Part 1: 359,007 ft³

Part 2: 216 times smaller

Part 3: 21600%

Step-by-step explanation:

Part 1:

The parameters for the tank are;

The radius of the tank = 70 feet

The volume of a sphere = 4/3·π·r³

Therefore, the volume of a quarter sphere = 1/4×The volume of a sphere

The volume of a quarter sphere = 1/4×4/3·π·r³ = π·r³/3

Plugging in the value for the radius gives

Volume = π×70³/3 = 114,333.33×3.14 = 359,006.7≈ 359,007 ft³.

Part 2:

The dimension of the scale model  = 1/6 × Actual dimension

Therefore, we have the radius of the sphere of the scale model = 1/6 × 70

Which gives;

The radius of the sphere of the scale model = 35/3 = 11.67 feet

The volume of the scale model = π·r³/3 = (3.14×11.67³)/3 = 1662.07 ≈ 1662 ft³

The number of times smaller the scale model is than the actual volume = (Actual volume)/(Scale model) = (359,007 ft³)/(1662 ft³) = 216 times

The number of times smaller the scale model is than the actual volume =  216 times = (1/Scale of model)³ = (1/(1/6))³ = 6³.

Part 3:

The percentage of the mock-up, x, to the volume of the actual tank is given as follows

x/100 ×  1662  = 359,007

∴ x = 216 × 100 = 21600%

The percentage of the mock-up, to the volume of the actual tank is 21600%.

Adrian would need to buy 13 tins of red paint to paint the area of the first wall of the community centre.

The wall of the community center is divided into 11 stripes, and Adrian needs to paint the stripes with red and pink shades. The first stripe is red, and the rest is in the shades of pink made by mixing the red and white paint in different ratios. The last stripe is white.The total area of the wall to be painted is the sum of areas of all the stripes. The area of a stripe is the product of the width of the stripe and the height of the wall. Hence, the area of a stripe is 10 m × 6 m = 60 m².The total area of the wall is the product of the height of the wall and the sum of widths of all the stripes. Hence, the total area of the wall is 6 m × (10 + 9 + 8 + ... + 1) m = 6 m × 55 m = 330 m².The area painted with red paint is 10 m × 6 m = 60 m². The area painted with the first shade of pink is (9/10) × 60 m² = 54 m². The area painted with the second shade of pink is (8/10) × 60 m² = 48 m². Hence, the areas painted with shades of pink decrease by 6 m² for each stripe.The total area painted with shades of pink is the sum of areas painted with all the shades of pink. Hence, the total area painted with shades of pink is 54 m² + 48 m² + ... + 6 m² = (9 + 8 + 7 + ... + 1) × 6 m² = 6 m² × 45 = 270 m².The total area painted with red paint and the shades of pink is 60 m² + 270 m² = 330 m², which is the total area of the wall. Hence, Adrian would not need to paint any area with white paint, and all the paint would be red or pink.The area covered by 1 litre of paint is 12 m². Hence, Adrian would need (330 m²)/(12 m²/litre) ≈ 27.5 litres of paint.Adrian would mix red and white paint in different ratios to make pink shades. Hence, Adrian would need to buy only red paint. The total area painted with red paint is 60 m². Hence, Adrian would need (60 m²)/(12 m²/litre) = 5 litres of red paint. Since Adrian would buy all the paint in 1-litre tins, Adrian would need to buy 5 tins of red paint.

The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two. Therefore, the answer to the question is B) 25.

We are given the initial value of the Count as 23. The statement Count = Count + 2 assigns the value of the Count variable to itself, incremented by two.

This implies that the value of Count is 23+2= 25 after the statement is executed.

In other words, the right-hand side of the equals sign is evaluated before the value is assigned to the left-hand side of the equals sign.

In this case, the right-hand side is Count + 2, which is equal to 23+2= 25.

The value 25 is then assigned to the variable Count on the left-hand side of the equals sign.

As a result, the value of Count after executing the statement Count = Count + 2 is 25.

Thus, option B) 25 is the correct answer to the given question.

The paired t-test can be used to determine if there is a significant difference in the mean speeds of the two microprocessors. We calculate the t-statistic and find the corresponding 95% confidence interval for the difference in mean speeds.

The differences in speed for each code are as follows: 4.4, -2.7, 7.5, -0.3, -3.2, 7.9. The mean difference is 2.67 seconds, and the standard deviation of the differences is 4.76 seconds. Using the t-distribution with n-1 degrees of freedom (where n is the number of pairs), we can calculate the t-statistic for a two-tailed test at the 0.05 level of significance. The t-statistic is 1.76, which corresponds to a 95% confidence interval for the difference in mean speeds of (-1.47, 6.81) seconds.

Therefore, we can be 95% confident that the true difference in mean speeds between the two processors falls within the range of -1.47 to 6.81 seconds. This means that we cannot reject the null hypothesis that there is no significant difference in mean speeds between the two processors at the 0.05 level of significance. However, it is important to note that the sample size is small and the assumption of normality may not hold, so the results should be interpreted with caution.

Answer:

non-linear, y = -6, x = 2 & x = 6, y = 2 & x = 4, above.

Step-by-step explanation:

The graph is not a straight line so that means that it is linear.

The y-intercept is the point at which the function touches the y-axis, which is at the coordinate point (0, -6), so y = -6.

The x-intercepts are the points at which the function touches the x-axis, which is at x = 2 and x = 6.

The highest y value is y = 2, and it happens when x =4.

Between x = 2 and x = 6, the function is above the x-axis line, so that means it must be above 0.

We can determine how much interior room a cylinder has by measuring its volume. The volume would be the same as how much material would fill the full can if you had one.

Volume of cylinder = π*r²*h

r is the radius and h is the height.

For given cylinder:

r = 4 ft and h = 9 ft

Volume of given cylinder = π*4²*9

Volume of given cylinder = 144π cu. ft.

To have 200 kg of a substance with a moisture content of 11%, the total dry weight required would be approximately 224.72 kg. If you have 200 kg of a substance with a specific gravity of 1.2 and density of 1.3 t/m³, the total amount of the element in the 200 kg would be 240 kg.

To calculate the total dry weight required to have 200 kg of a substance with a moisture content of 11%, you need to account for the moisture content. Since the moisture content is 11%, the dry weight of the substance is 89% (100% - 11%). Therefore, you can calculate the dry weight by dividing the desired weight (200 kg) by the dry weight fraction (0.89): 200 kg / 0.89 = 224.72 kg. So, the total dry weight required to have 200 kg of the substance is approximately 224.72 kg.

If you have 200 kg of a substance with a specific gravity of 1.2 and a density of 1.3 t/m³, you can calculate the total amount of the element by multiplying the mass (200 kg) by the specific gravity: 200 kg * 1.2 = 240 kg. Therefore, you have a total of 240 kg of the element in the 200 kg of the substance.

To have 200 kg of a substance with 11% moisture content, you would need a total dry weight of approximately 224.72 kg. Additionally, if you have 200 kg of a substance with a specific gravity of 1.2 and density of 1.3 t/m³, you would have a total of 240 kg of the element.

Answer:

Yes; they should charge $3.30 for an apple and $2.00 for an orange.

Step-by-step explanation:

We can answer this question by creating some simultaneous equations.

Let \(x\) = an apple and let \(y\) = an orange.

With the information given, we can say that the price for an apple and an orange is equal to $5.30 while the price for an apple and 2 oranges is equal to $7.30.

Therefore:

\(x+y = 5.30\)   (1st equation)

\(x + 2y = 7.30\) (2nd equation)

There are a couple of ways to solve these equations but I'll show you the substitution method. This is when we substitute the value of one of the equation into the other one.

So let's re-arrange one of them.

\(x+y=5.30\) can be re-arranged into \(x= 5.30-y\)

Now we know the value of \(x\), we can replace the \(x\) in the second equation.

Therefore \(5.30-y + 2y=7.30\). We can simplify this to give us \(5.30 + y = 7.30\) and re-arrange to solve for y: \(y = 2\).

Now we know the value of y, let's put it into the first equation:

\(x+2 =5.30\)

and solving for \(x\) we get: \(x = 3.30\).

Therefore the price of an apple (\(x\)) is $3.30 and the price of an orange (\(y\)) is $2.

From the list of answers, there is only one correct option which is:

- Yes; they should charge $3.30 for an apple and $2.00 for an orange.
