On the main floor of a theatre the number of seats per row increases at a constant rate. Jack counts 31 seats in row 3 and 37 seats in row 6. How many seats are there in row 20
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.
How many seats are in row 20?
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

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]
The heights of a group of trees is normally distributed with a mean of 14.3 feet. If the z score for a 20-foot y’all tree is 1.9, what is the standard deviation?
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]

Therefore, the container can hold 810 cubic cm of macadamia nuts.
Write an equation of the line that is parallel to 2x + 4y = 6 and passes through the point (6, 4).
A) y = 2x + 4
B) y = 2x - 8
C) y = -2x + 16
D) y = -12x + 7
Answer:
The answer is D my friends. Good luck.
Step-by-step explanation:
The equation of the line parallel to 2x + 4y = 6 and passing through the point (6, 4) is y = -0.5x + 7.
Explanation:To find an equation of a line parallel to a given line, we need to find a line with the same slope.
First, we need to rewrite the original equation 2x + 4y = 6 in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
By rearranging the equation, we get y = -0.5x + 1.5.
Since the new line is parallel to the original line, it will have the same slope.
Therefore, the equation of the line parallel to 2x + 4y = 6 and passing through the point (6, 4) is y = -0.5x + 7.

7. John's seafood restaurant is trying to estimate its profits. John has found that on average, each meal served costs the restaurant $14.56 and takes in $17.12. John has also found that on average, each beverage served costs the restaurant $1.20 and takes in $5.40. If c customers order a meal, and half of those customers order a beverage, which of the following functions models the restaurant's total profit?
f(c) =17.12c -14.56c + 5.40(.5c) - 1.20(.5c)
f(c) = 17.12c - 14.56c + 5.4c - 1.20c
f(c)=14.56c - 17.12c + 1.20c - 5.40c14.56c - 17.12c + 12(.5c) - 5.40(.5c)
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)

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

The diameter of the base of the cone measures 8 units.
The height measures 6 units.
What is the volume of the cone?
A)240 cubic units
B)321 cubic units
C)48X cubic units
D)647 cubic units
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]
[tex]V_{cone}=32\pi \ units^3[/tex]

The Eiffel Tower is 984 feet. A model of the tower is 24 inches tall. What is the ratio of the height of the model to the height of the actual Eiffel Tower?
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.
Explanation: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.

Sondra wants to put a fence in a triangular area of her backyard as shown in the illustration. The fence will enclose a right triangle, with two of the sides measuring 8 yards and 15 yards long. How long will the third side of the triangle be?
(the question did not contain an illustration)
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.
