[tex]\frac{2}{243} (82^\frac{3}{2} -1)[/tex] is the required length of the curve y = 4 + 6[tex]x^\frac{3}{2}[/tex]
Given equation of curve:

let 1+81x be t
81dx = dt
as the value of x changes after the substitution of the value.

At center street middle school, 240 scholars voted for their middle school play. the ratio of scholars who voted for annie to scholars who voted for wicked was 5 : 2, and the ratio of scholars who voted for wicked to scholars who voted for the wizard of oz was 2 : 3. how many scholars voted for wicked?
The number of scholars who voted for the play named Wicked will be equal to 48.
This problem can be solved by using the concept of Ratio. It is given that the total number of students are 240. Now, the ratio of Annie to Wicked is equal to 5:2 and ratio of Wicked to Wizard Oz is equal to 2:3. If we assume that the number of people who voted for Annie is 'x', the number of people who voted for Wicked is 'y' and number of people who voted for Wizard Oz is 'z'. Now, we write the expressions as
x/y = 5:2; from this we get x = 5y/2 ....(1)
y/z = 2:3; from this we get z = 3y/2 ....(2)
x + y + z = 240 ....(3)
We use the above values of equation (1) and (2) in equation (3) as
5y/2 + y + 3y/2 = 240
4y + y = 240
5y = 240
y = 48
So, the number of students who voted for Wicked will be 48.

Find the equation of the line, given the following information:
Passes through (-9,3) and is perpendicular to
y=1/2x+6
Answer:
y=2/5x + 33/5
Step-by-step explanation:
To find the equation of the line that passes through the point (-9,3) and is perpendicular to y = 1/2x + 6, we can first find the slope of the given line y = 1/2x + 6. The slope of a line is equal to the rise (the change in the y-coordinate) divided by the run (the change in the x-coordinate), so we can find the slope of the line y = 1/2x + 6 as follows:
Slope = (change in y) / (change in x)
= (1/2 - 6) / (1 - 0)
= -5/2
Since the line we are looking for is perpendicular to the line y = 1/2x + 6, its slope must be the negative reciprocal of the slope of y = 1/2x + 6. The negative reciprocal of a number is equal to the negative of the reciprocal of the number, so the slope of the line we are looking for is equal to -1 / (-5/2) = 2/5.
Next, we can use the point-slope form of a line to find the equation of the line that passes through the point (-9,3) and has a slope of 2/5. The point-slope form of a line is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. Substituting the values for the given point and the slope into this equation, we get:
y - 3 = 2/5(x - (-9))
y - 3 = 2/5(x + 9)
Next, we can distribute the 2/5 on the right-hand side of the equation to get:
y - 3 = 2/5x + 18/5
Finally, we can combine like terms on both sides of the equation to get the final equation of the line:
y=2/5x + 18/5 + 3
y=2/5x + 33/5

The midpoint of AB is M(3,-3). If the coordinates of A are (2, -1), what are the
coordinates of B?
Answer:
The coordinates of B is (4, 7)
Step-by-step explanation:
To find the answer for B, you have to do the inverse of the midpoint formula, which is M equals (x1 multiplied by x2, over 2; y1 multiplied by y2, over 2).
If you substitute in A's coordinates for x1 and y1, you come up with (3, 3) = (2+x, over 2; and -1+y, over 2)
If the x coordinate answer for AB was 3, you can create an equation like this to solve for B's x coordinate: 2+x over 2 equals 3.
you multiply 2 by 3 to get 6---> 2+x=6-----> x=4
If the y coordinate for AB was also three, you can create another equation to solve for B's y coordinate: -1+y over 2 equals 3.
you multiply 2 by 3 to get 6 again---->so -1+y=6---->y=7
so the answer for B's coordinates is (4, 7).
Answer:
B(4, - 5)--------------------------
Given:
A = (2, - 1), Midpoint M = (3, - 3),Find the coordinates of the other end point B.
Use midpoint equation, considering point B as (x, y):
3 = (2 + x)/2 ⇒ 2 + x = 2*3 ⇒ 2 + x = 6 ⇒ x = 4,- 3 = (- 1 + y)/2 ⇒ -1 + y = 2*(-3) ⇒ -1 + y = - 6 ⇒ y = - 5.Therefore the point B has coordinates of (4, - 5).

the width of a rectangle is two feet less than the length. the perimeter is 52 feet. find the length and the width.
If the width of a rectangle is two feet less than the length and the perimeter is 52 feet, then the length and width of the rectangle is 14 feet and 12 feet respectively
The width of a rectangle is two feet less than the length
Consider the length of the rectangle as x
Then the width of the rectangle = x - 2
The perimeter of the rectangle = 52 feet
The perimeter of the rectangle = 2(l + w)
Where l is the length and w id the width
Substitute the values in the equation
2(x + x - 2) = 52
2(2x - 2) = 52
2x - 2 = 52/2
2x - 2 = 26
2x = 28
x = 14 feet
Width of the rectangle = 14 - 2

Answer:
c = 52/x
Step-by-step explanation:
We have 52 total cans and x bags of with an equal amount of cans in each.
Thus, we would have c = 52/x cans per bag. This is probably the answer you are looking for.
However, this can evaluate to a fractional number of cans, so you may be looking to round that answer down to an integer. In that case, the answer would be c = ⌊52/x⌋, which is solving for the greatest integer less than the value of 52/x

Property
The property illustrated in the statement "If ∠A ≅ ∠B, ∠B ≅ ∠C, then ∠A ≅ ∠C" is the Transitive Property.
This property states that if two elements are related by a certain relationship, and another element is related to the second element by the same relationship, then the first and third elements are related by the same relationship.
In this statement, the relationship is that of congruency, meaning that each angle has the same measure. Therefore, the Transitive Property states that if angle A is congruent to angle B, and angle B is congruent to angle C, then angle A is congruent to angle C.
The other three properties listed do not apply to this statement. The Reflexive Property states that a given element is related to itself by a certain relationship, which does not apply to this statement.
The Symmetric Property states that if two elements are related by a certain relationship, then the two elements are related to each other in the same way, which is not applicable in this statement.
Lastly, the Addition Property states that the sum of two elements related by a certain relationship is related to the two elements by the same relationship, which is not applicable in this statement.

In a canoe race, the distance y (in miles) that Team A travels in x hours is represented by y = 5.5x. Team B travels 4 miles per hour and is 3 miles ahead of Team A. The teams continue traveling at their current rates for the remainder of the race. Will Team A catch up to Team B? Use a system to solve and explain your answer.
Answer:
Team A catches up to B in 2 hours, at the 11 mile mark
Step-by-step explanation:
(5.5 mi/hr)(x) = (4 mi/hr)(x) + 3 mi
(1.5 mi/hr)(x) = 3 mi
x = 3/1.5 = 2 hours

Earth’s distance from the sun is 1.496 x 108 km. Saturn’s distance from the sun is 1.4246 x 109 km. How many times further from the sun is Saturn?
Saturn's distance is 9.5 farther from the Sun than the earth.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Earth's distance from the sun = 1.496 x [tex]10^8[/tex] km
Saturn's distance from the sun = 1.4246 x [tex]10^9[/tex] km
Divide Saturn's distance by Earth's distance.
= 1.4246 x [tex]10^9[/tex] / 1.496 x [tex]10^8[/tex]
= 9.5
We see that,
Saturn's distance from the sun x 0.95 = Earth's distance from the sun.
Thus,
Saturn's distance is 0.95 farther from the sun.

The number of free throws that adam can expect to make if he attempts 20 free throws is 14.
Probability is a metric used to express the possibility or chance that a particular event will occur. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Given the probability that the person making a free throw is 70%. The question asks to estimate how many of his 20 free throw attempts will be successful.
Then, the number of free throws is calculated as follows,
[tex]\begin{aligned}\text{70\% of 20}&=\frac{70\times20}{100}\\&=14\end{aligned}[/tex]
Then, the number of successful free throws is 14.
