The area of a parallelogram is given by

[tex]A=bh[/tex]

Now, if we consider the 9.9 inches side as the base, then the height is the one labeled with 5.5 inches.

If instead we choose the 11 inches side as the base, the height is h.

So, we can express the area in this two equivalent ways:

[tex]A = 9.9\cdot 5.5 = 11\cdot h[/tex]

Solving for h, we have

[tex]h = \dfrac{9.9\cdot 5.5}{11} = 4.95[/tex]

Answer:

tire A=39 revolutions

tire B=38 revolutions

tire C= 37 revolutions

Step-by-step explanation:

The question is on circumference

Tire A diameter = 15 +4.60+4.60=24.20 inches

Tire B diameter= 16+4.43+4.43=24.86 inches

Tire C diameter=17+4.33+4.33=25.66 inches

Finding the circumference/single revolution

Tire A = 2×3.14×24.20=151.98 inches

Tire B= 2×3.14×24.86=156.12 inches

Tire C=2×3.14×25.66=161.15 inches

Number of revolutions made

Track length=500 feet.............change feet to inches

500×12=6000inches

Revolutions for tire A= 6000/151.98 =39.47⇒39 revolutions

Revolutions for tire B=6000/156.12 =38.43⇒38 revolutions

Revolutions for tire C= 6000/161.15 =37.23⇒37 revolutions

To calculate probabilities of certain observations concerning different variables, we need relevant data pertaining to those variables. Without this data, it's challenging to calculate precise probabilities. In such cases, we use the closest available data or make educated assumptions.

To find the probability of different observations, we need specific data that relates to those situations. For example, to find the probability that an observation is on a Thursday when the temperature is between 90 and 99, we would need historic data that captures temperature observations on Thursdays. Similarly, other probabilities also need specific data. For instance, to know the probability of an observation being on a Monday with temperature less than 90, or a Friday where the temperature is greater than 89, we would need historic temperature measurements for these specific days. However, since the provided information doesn't include specific data needed to calculate the probabilities asked in the question, we can't provide precise probabilities. Probability in statistics is generally calculated based on relevant data that is representative of the situation of interest. In situations where it is necessary to estimate the probability without access to specific data, we might use available data that is as closely matching as possible, or might make educated assumptions.

Answer:

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

Step-by-step explanation:

Profit is the difference between revenue (17.12c +5.40(.5c)) and cost(14.56c+1.20(0.5c)). That difference is expressed by the function shown above.

Answer:

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

Step-by-step explanation:

Let's build the f(c) function by steps.

There are c customers.

John has found that on average, each meal served costs the restaurant $14.56 and takes in $17.12.

So, the costs for the restaurant are negative, and what takes positive.

f(c) =17.12c -14.56c

Now the final part

John has also found that on average, each beverage served costs the restaurant $1.20 and takes in $5.40.

Half of these customers order a beverage, and this is why we multiply by 0.5.

So

f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)

Answer:

  y = (1/2)|x -8| -3

Step-by-step explanation:

The first five points fall on a straight line with a slope of ...

  ∆y/∆x = -0.5/1 = -0.5

The last point is not on that line.

So, several options are available:

Answer: 65 seats in row 20

Step-by-step explanation: 3 = 31, 6 = 37 the difference is 3 rows but 6 seats so its going up 2 every row therefor you need 14 rows after row 6 so 14 * 2 + 37 = 65 seats

By finding a linear equation, we will see that on the row 20 there are 65 seats.

Here we have a linear relationship, that can be written as:

y = a*x + b

Where a is the slope and b the y-intecept.

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂), the slope is:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case, we have points of the form (row, seats), and the two points that we have are:

(3, 31) and (6, 37)

So the slope is:

[tex]a = \frac{37 - 31}{6 - 3} = 2[/tex]

So the equation is:

y = 2*x + b

To find the value of b, we replace one of the points in the equation. If we use the first one, we have x = 3 and y = 31, so:

31 = 2*3 + b

31 = 6 + b

31 - 6 = 25 = b

The equation is:

y = 2x + 25

The number of seats in row 20 is what we get if we replace x by 20, then:

y = 2*20 + 25 = 65

Zeituni should itemize her deductions, as the total of her state taxes and mortgage interest ($5850) is more than her standard deduction ($5700). So the correct answer is B.

To decide whether Zeituni should use her standard deduction or itemize her deductions, we should add up her state taxes and mortgage interest. The total of her state taxes ($4670) and mortgage interest ($1180) comes to $5850. Comparing this with her standard deduction of $5700, we can see that $5850 is more than $5700. Thus, the better option would be for Zeituni to itemize her deductions.

Answer:

The standard deviation of the heights of the group of trees is 3 feet

Step-by-step explanation:

For a normal distribution, the z-score corresponding to a particular observed value is calculated as;

z-score = (observed value - mean) / (standard deviation)

The mean is given as 14.3

The z-score is 1.9

The observed value is 20 (the given height)

We can make the standard deviation to be the subject of the formula in the above equation;

standard deviation = (observed value - mean) / ( z-score)

We then substitute the given values into this equation;

standard deviation = [tex]\frac{20-14.3}{1.9}=3[/tex]

12x18.2/2=109.2 is the area of the big triangle and also the same area could be found 20 x h=109.2 so

Answer:

The ratio is [tex]\frac{1}{492}[/tex]

Step-by-step explanation:

Remember that

1 ft=12 in

The Eiffel Tower is 984 feet

Convert to inches

984 ft=984*12=11,808 in

Find the ratio of the height of the model to the height of the actual Eiffel Tower

The height of the model is 24 in

The height of the actual Eiffel Tower is 11,808 in

the ratio is equal to

[tex]\frac{24}{11,808}=\frac{1}{492}[/tex]

That means----> The height of the actual Eiffel Tower is 492 times greater than the height of the model

To find the ratio of the height of the model to the actual Eiffel Tower, convert the model's height to feet (24 inches = 2 feet) and then divide by the tower's height (2 feet / 984 feet) to get the simplified ratio of 1:492.

To calculate the ratio of the height of the model Eiffel Tower to the actual Eiffel Tower, we need to ensure both measurements are in the same unit. Since the actual Eiffel Tower's height is given in feet and the model's height is in inches, we will convert one of these measurements so they can be directly compared.

First, we convert the model's height from inches to feet. We know that 1 foot equals 12 inches, so:

24 inches × (1 foot / 12 inches) = 2 feet.

Now we have the model's height in feet, and we can form the ratio:

Height of model / Height of actual Eiffel Tower = 2 feet / 984 feet.

By simplifying this fraction, we get:

1 / 492.

So, the ratio of the height of the model to the height of the actual Eiffel Tower is 1:492.

17 yards. The fence that enclose Sondra's backyard is a right triangle whose sides measuring 8 yards, 15 yards and 17 yards  respectively.

The key to solve this problem is using the Pythagorean Theorem that dictates; In every right triangle the square of the hypotenuse is equal to the sum of the squares of the legs and the equation hypotenuse²=leg1²+leg2².

For this problem we know the measuring of two side, which mean that we can apply Pythagorean Theorem equation as follow:

Let's say that one of the side is a = 8yards, and the other side is b = 15yards. So, we want to know how long the third side c long.

Applying the Pythagorean Theorem:

[tex]c^{2} =a^{2}+b^{2}  \\c=\sqrt{a^{2}+b^{2}}[/tex]

Substituting the values of the sides a and b:

[tex]c=\sqrt{(8yards)^{2}+(15yards)^{2}}\\c=\sqrt{64yards^{2}+225yards^{2}}\\c=\sqrt{289yards^{2}}\\c=17yards[/tex]

Answer:

17 yds

Step-by-step explanation:

Lacking further info about this situation, I will assume that 8 yards and 15 yards represent the two legs of this right triangle, and not the hypotenuse.  If that's the case, then the hypotenuse is found by applying the Pythagorean Theorem:

(8 yd)² + (15 yd)² = hyp², or

64 yd² + 225 yd² = 289 yd²

Taking the square root of this result yields 17 yds.

The third side will be 17 yds long.

Answer:   [tex]32\pi[/tex] cubic units.

Step-by-step explanation:

You can use this formula for calculate the volume of a cone:

[tex]V_{cone}=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" is the height.

You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

[tex]r=\frac{8units}{2}\\\\r=4units[/tex]

Since you already know that height and  the radius, you can substitute them into the formula. Then, the volume of this cone is:

[tex]V_{cone}=\frac{1}{3}\pi (4units)^2(6units)[/tex]

Step-by-step explanation:

We have been given an image of a container. We are asked to find the volume of nuts could the container hold.

We can see that our given container is in form of cuboid, so we will use volume of cuboid formula to solve our given problem.

[tex]\text{Volume of cuboid}=\text{Length*Width*Breadth}[/tex]

Upon substituting our given values in above formula, we will get:

[tex]\text{Volume of container}=18\text{ cm}\times 15\text{ cm}\times 3\text{ cm}[/tex]
