You're at a halloween fair with a big ferris wheel. the wheel has ten chairs and people are seated two per chair. every minute a chair passes the exit platorm. the wheel opens at 11 am for thirty minutes -- how many people took a ride in that time?

Answers

Answer 1
The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,

         n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)

Substituting the known values to the equation,

       n = (30 minutes)(1 chair / minute)(2 persons / chair)
                 n = 60 persons

Answer: 60 persons
Answer 2

The number of persons who have taken the ride is 60.

According to the question, a halloween fair with a big ferris wheel. The wheel has 10 chairs and people are seated [tex]2/chair[/tex].

Also, every minute a chair passes the exit platform and the wheel opens at 11 am for thirty minutes so, the rate at which the chair passes the exit platform is [tex]1\;chair\;per\;minute[/tex].

Now, number of persons who have taken the ride is calculated as-

[tex]n= minutes \times (1\;chair\;per\;minute)\times (2\;persons\;per\;chair)\\n=30\times 2\times 1\\n=60[/tex]

Hence, the number of persons who have taken the ride is 60.

A game shop sells marbles in clear plastic cylinders. Four marbles fit across the diameter of the cylinder and 10 marbles fit from the base to the top of the cylinder. Each marble has a diameter of 2 cm. What is the area of the plastic that is needed to make one cylinder?

Answers

To start, you know that this question is asking for the surface area of one of the cylinders, and the formula to finding the surface area of a cylinder is A=2πrh+2πr^2.

Now, to find the surface area, you first need to figure out the height of the plastic cylinder and its radius. 
Since you know that the diameter (twice the radius) of the cylinder is equivalent to 4 marbles, and each marble has a diameter of 2 cm, the diameter of the cylinder would be 8 cm. Then, to find its radius, you divide by 2, so its radius is 4.
Now, since you know that the height of the cylinder is 10 marbles, you multiply 10 by 2 to get that the height is 20 cm tall. 
Since you now have the values of the height and the radius, plug the values into the surface area of a cylinder formula (r is radius and h is height).
A=2π(4)(20)+2π(4)^2.
Assuming that pi is 3.14, when you simplify this using PEMDAS, you get 
502.4+100.48 which then simplifies to 602.88, the area of the plastic to make one cylinder.

A train leaves chicago and travels east at 60 mph. another train at the same depot leaves at the same time and travels west at 72 mph. how long before the two trains are 330 miles apart?

Answers

Final answer:

The two trains will be 330 miles apart after 2.5 hours.

Explanation:

To find how long it takes for the two trains to be 330 miles apart, we can apply the formula for relative velocity:



Relative velocity = sum of their speeds



The first train is moving east at 60 mph, and the second train is moving west at 72 mph. So their relative velocity is 60 mph + 72 mph = 132 mph.



To find the time it takes for the trains to be 330 miles apart, we can use the formula:



Distance = speed × time



330 miles = 132 mph × time



Solving for time, we have:



Time = 330 miles / 132 mph = 2.5 hours

What is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 2 units?

4 units
2 units
Square root of 6 units
Square root of 8 units

Answers

Answer:

square root of 8

Step-by-step explanation:

because it is 8 squared

Final answer:

The length of the hypotenuse of a right triangle with legs of 2 units each is the square root of 8 units.

Explanation:

In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. If each of the two legs is 2 units, then the length of the hypotenuse can be found as follows:

hypotenuse2 = leg12 + leg22

hypotenuse2 = 22 + 22

hypotenuse2 = 4 + 4

hypotenuse2 = 8

Therefore, the length of the hypotenuse is the square root of 8 units.

How do you find a literal equation for d=rt,
solve for t.

Answers

d = rt

d/r = t       divide both sides by r

t = d/r       <<< the equation

hope this helped, God bless!

Answer: [tex]\frac{d}{r} = t[/tex]

Step-by-step explanation: To solve for t in the equation d = rt, all we have to do is get t by itself on the right side of the equation.

Since t is being multiplied by r, we simply divide both sides of the equation by  r. On the right, the r's cancel and we are left with r.

On the left side of the equation we have [tex]\frac{d}{r}[/tex].

Therefore, our answer is [tex]\frac{d}{r} = t[/tex].

What is the equation of a line that passes through the point (4, 2) and is perpendicular to the line whose equation is y=x/3−1 ?

Answers

The line y = x/3 - 1, or y = (x/3) - 1, is the same as y = (1/3)x - 1
The slope here is 1/3 as this equation is in y = mx+b form (m = slope, b = y intercept)

Using the starting point of 1/3, we will...
Flip the fraction: 1/3 ----> 3/1 = 3
Then flip the sign from positive to negative:  3 ----> -3

The original slope is 1/3
The perpendicular slope is -3
The two slopes multiply to -1
We'll use m = -3 along with x = 4 and y = 2
We generate those x,y values from (x,y) = (4,2) as the given point

Plug m = -3, x = 4, y = 2 into the equation below. Solve for b
y = mx+b
2 = -3*4 + b
2 = -12 + b
2+12 = -12+b+12
14 = b
b = 14

So because m = -3 and b = 14, we go from y = mx+b to y = -3x+14

--------------------------------------------------------------------------------

Final Answer: y = -3x+14

A college student borrows ​$3,000 for 3 months to pay for a semester of school. If the interest is ​$61.88 find the monthly payment

Answers

Given:
Amount borrowed = $3,000
Interest = $61.88
Duration = 3 months

Obligation = 3000 + 61.88 = 3061.88
Monthly payment = 3061.88/3 = $1,020.63

Answer: $1,020.63

The student must make monthly payments of $1,020.63 to repay the $3,000 loan with $61.88 in interest over 3 months.

The student has borrowed $3,000 for 3 months and the interest incurred on this loan is $61.88. To find the monthly payment, we need to add the total interest to the principal borrowed and then divide it by the number of payments (which is 3 in this case).

The total repayment amount is calculated as $3,000 principal + $61.88 interest = $3,061.88.

Now, we divide the total repayment amount by the number of monthly payments:

Monthly Payment = Total Repayment Amount / Number of Payments

Monthly Payment = $3,061.88 / 3

Monthly Payment = $1,020.63

Therefore, the student will need to make monthly payments of $1,020.63 to repay the $3,000 loan over 3 months.

Assume the ball passes through the points (3,8), (5,20/3), and (6,5) . Use this data to set up a system of three equations and three unknowns (a, b, and c) that will allow you to find the equation of the parabola. Write the system in the space provided.

Answers

A parabola is the shape of the graph of a quadratic function. Quadratic functions have the general form:

[tex]y=ax^2+bx+c[/tex]

Here, you've been given the x and y values for three points on the parabola, and you've been asked to set up a system of equations that include those three points. All this problem is really asking is to plug each of those values into the general equation.

The system should look like:

[tex]\begin{array}{lcl} 3^2a+3b+c & = & 8 \\ 5^2a+5b+c & = & 20/3 \\ 6^2a+6b+c & = & 5 \end{array}[/tex]

Which, when simplified, looks like:

[tex]\begin{array}{lcl} 9a+3b+c & = & 8 \\ 25a+5b+c & = & 20/3 \\ 36a+6b+c & = & 5 \end{array}[/tex]

To solve this question:

First, we need to know the standard equation of a parabola.Then, with the three points given, we can build a system of three equations.

Doing this, we get that the system is, with the 3 equations:

[tex]9a^2 + 3b + c = 8[/tex]

[tex]75a + 15b + 3c = 20[/tex]

[tex]36a + 6b + c = 5[/tex]

Equation of a parabola:

A parabola is a second degree polynomial, having an standard equation of:

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

Point (3,8)

This means that when [tex]x = 3, y = 8[/tex]. So

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]8 = a\times3^2 + 3b + c[/tex]

[tex]9a^2 + 3b + c = 8[/tex]

Thus, [tex]9a^2 + 3b + c = 8[/tex] is the first equation.

(5,20/3)

This means that when [tex]x = 5, y = \frac{20}{3}[/tex]. Thus

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]\frac{20}{3} = a\times5^2 + 5b + c[/tex]

[tex]25a + 5b + c = \frac{20}{3}[/tex]

[tex]75a + 15b + 3c = 20[/tex]

Thus, [tex]75a + 15b + 3c = 20[/tex] is the second equation.

(6,5)

This means that when [tex]x = 6, y = 5[/tex]. Thus

[tex]y = ax^2 + bx + c, a \neq 0[/tex]

[tex]5 = a\times6^2 + 6b + c[/tex]

[tex]36a + 6b + c = 5[/tex]

Thus, [tex]36a + 6b + c = 5[/tex] is the third equation.

After all, the system of equations is:

[tex]9a^2 + 3b + c = 8[/tex]

[tex]75a + 15b + 3c = 20[/tex]

[tex]36a + 6b + c = 5[/tex]
