The Ferris wheel at the Comal County Fair is a three minute ride that takes its riders on a thrilling ride up to a maximum height of 105 feet and a low point of 5 feet. Assuming that the Ferris wheel rotates at 6 revolutions per minute and a rider starts his stopwatch immediately as his ride starts at its low point,
Final answer:
In a Ferris wheel, gravity and normal forces act on riders, affecting circular motion and contributing to centripetal force. Redistribution of mass affects the moment of inertia and could change angular velocity, assuming conservation of angular momentum without external torques.
Explanation:
Understanding the forces acting on people in a Ferris wheel and the effects on angular velocity and angular momentum involves comprehending basic physics concepts of circular motion and rotational dynamics.
Angular velocity is affected by how fast the Ferris wheel rotates. If the wheel accelerates, angular velocity increases. The total angular momentum of the system, a product of moment of inertia and angular velocity, can change due to external torques, like the motor driving the Ferris wheel or resistance due to air. However, in the absence of external torques, the system's angular momentum remains constant.
Considering the positions of people on the Ferris wheel (4 o'clock, 1 o'clock, 9 o'clock, and 6 o'clock), gravity acts downwards on each person, and the normal force acts perpendicular to the wheel's surface. These forces contribute to the centripetal force that keeps the people in circular motion. The redistribution of mass as people move or as the wheel turns can change the wheel's moment of inertia, potentially altering its angular velocity assuming angular momentum is conserved in the absence of external torques.

which property does the equation below represent 17•44+17•56=17•100
The equation represents the distributive property, a fundamental concept in algebra where a number is distributed across an addition inside a parenthesis, and then the individual products are summed.
Explanation:The equation 17⋅44+17⋅56=17⋅100 showcases the distributive property of multiplication over addition. The distributive property allows one to multiply a number by a group of numbers added together by doing each multiplication separately and then adding the results. This property is very useful in algebra and simplifying mathematical expressions. In this case, 17 is multiplied by 44 and 56 individually, and then the products are added to get the same result as multiplying 17 by the sum of 44 and 56, which is 100.

A glass triangular prism for a telescope is 5.5 inches long. each side of the prism´s triangular bases is 4 inches long and about 3 inches high. About how much glass covers the surface of the prism?
The surface area of the glass triangular prism is 78 square inches.
Explanation:To find the surface area of the glass triangular prism, we need to find the area of each face and then sum them up. The prism has two triangular bases and three rectangular faces. The area of each triangular base is given by the formula A = (1/2) * base * height, where the base is 4 inches and the height is 3 inches. Therefore, the area of each base is (1/2) * 4 * 3 = 6 square inches. The total area of both bases is 2 * 6 = 12 square inches.
The area of each rectangular face can be found using the formula A = length * height, where the length is 4 inches and the height is 5.5 inches. Therefore, the area of each rectangular face is 4 * 5.5 = 22 square inches. The total area of all three rectangular faces is 3 * 22 = 66 square inches.
Finally, we can find the total surface area by adding the area of the bases and the area of the faces: 12 + 66 = 78 square inches.

Parker is single and paying off his graduate student loan. The monthly payment is $679.34. He is hoping to receive an income tax refund that is large enough to make at least one monthly payment. His taxable income is $77,911 and his employer withheld $19,458 in federal taxes. a. How much of a refund will Tony receive? b. How many loan payments will Parker be able to make with this refund?
Parker will receive a tax refund of $2,318. With this refund, he can make approximately 3 loan payments.
Explanation:To determine Parker's tax refund and the number of loan payments he can make with this refund, we should consider his income and his withholdings. Since his taxable income is $77,911 and he has had $19,458 in federal taxes withheld, we can calculate his tax liability using the federal tax rates. In the U.S, the marginal tax rates for a single taxpayer range from 10% to 35%, depending on income.
For someone earning $77,911, they would be in the 22% tax bracket according to the 2020 tax tables from the Internal Revenue Service. The tax on income from $80,251 to $171,050 is 22%. Therefore, Parker's expected tax liability is $77,911 * 22% = $17,140.
However, the amount his employer withheld was $19,458. This means Parker has overpaid and is eligible for a refund of $19,458 - $17,140 = $2,318.
In terms of how many loan payments Parker can make with this refund, since his monthly loan payment is $679.34, he can make approximately $2,318/$679.34 = 3.41 payments.
Therefore, Parker will receive a tax refund of $2,318 and will be able to make approximately 3 loan payments with this refund.

Isaac has 21 green marbles and 7 blue marbles. He wants to place them in identical groups without any marbles left over. What is the greatest number of groups Isaac can make? PLEASE ANSWER WITH WORK!!!
Answer:
7 groups.
Step-by-step explanation:
We have been given that Isaac has 21 green marbles and 7 blue marbles. He wants to place them in identical groups without any marbles left over.
To find the greatest number of groups Issac can make we will find the GCF of 7 and 21.
Factors of 7 are: 1, 7.
Factors of 21 are: 1, 7, 3, 21.
We can see that 7 is the greatest common factor of 7 and 21, therefore, Issac can make 7 groups from 21 green marbles and 7 blue marbles.
Let us find number of each type of marble is each group.
[tex]\text{Number of green marbles in each group}=\frac{21}{7}[/tex]
[tex]\text{Number of green marbles in each group}=3[/tex]
Therefore, there will be 3 green marbles in each group.
[tex]\text{Number of blue marbles in each group}=\frac{7}{7}[/tex]
[tex]\text{Number of blue marbles in each group}=1[/tex]
Therefore, there will be 1 blue marble in each group.

A batch of muffins needs to bake in the oven for 22 minutes. They need to cool for at least 15 minutes before they should be eaten. Wade puts the muffins in the oven at 10:17 am. Select true or false for each statement.
a) Wade can eat muffins at 10;39 pm
b) wade can eat muffins at 10:44 am
c)Wade should take the muffins out of the oven at 10:39 pm
d) Wade should take the muffins out of the oven at 10:39 am
Wade placed the muffins in the oven at 10:17 AM; they will be ready to eat after baking and cooling at around 10:54 AM. The statements about eating the muffins at 10:39 PM and taking them out at 10:39 PM are false, while the statement about taking them out at 10:39 AM is true.
Explanation:To calculate when Wade can eat the muffins we must add the baking time and cooling time to the time he put the muffins in the oven. Wade puts the muffins in at 10:17 am and the muffins need to bake for 22 minutes. After baking, they need 15 minutes to cool.
First, the muffins would be done baking at 10:39 am (10:17 am + 22 minutes). Then, after cooling for at least 15 minutes, Wade can eat the muffins at 10:54 am (10:39 am + 15 minutes).
a) False: Wade cannot eat muffins at 10:39 pm because this time is 12 hours after the correct time.b) False: Wade cannot eat muffins at 10:44 am because they will only have cooled for 5 minutes, which is not enough.c) False: Wade should take the muffins out at 10:39 am, not pm.d) True: This is the correct time for Wade to take the muffins out of the oven.Big points+ brainliest
Liv and Ira are throwing balls in the air and catching them. Liv has caught 41 balls. Ira has caught 12 more balls than Liv.
How many balls has Ira caught?
Final answer:
Ira has caught 53 balls, which is found by adding 12 to Liv's total of 41 balls.
Explanation:
The question asks to find out how many balls Ira has caught if Liv has caught 41 balls and Ira has caught 12 more balls than Liv. To solve this, we start with the number of balls Liv has caught, which is 41. Since Ira has caught 12 more balls than Liv, we add 12 to Liv's total. Therefore, the number of balls caught by Ira is calculated as follows:
Liv's total = 41 balls
Ira's total = Liv's total + 12
Ira's total = 41 + 12 = 53 balls
Thus, Ira has caught 53 balls.

Find the area of a circle with a radius of 1.
Three brothers, Justin, Jared, and Jonathan decided to buy a present for their mom's birthday. Justin gave decided to spend 1/4 of his savings on the present, Jared said he will contribute 1/3 of his money, and Jonathan was willing to put in 2/5 of all he had. Each brother invested exactly the same amount of money and they bought a vase that costed $33.00. How much money did each boy have before the purchase?
Final answer:
Each brother spent $11 on the gift. To find their original savings, we calculate 4 * $11 for Justin, which is $44, 3 * $11 for Jared, which is $33, and 5/2 * $11 for Jonathan, which is $27.50.
Explanation:
The question is asking us to find out how much money each of the three brothers, Justin, Jared, and Jonathan, had before they each spent an equal amount on a present for their mom's birthday. They bought a vase for $33, and Justin spent 1/4 of his savings, Jared contributed 1/3 of his, and Jonathan gave 2/5 of his. We can set up an equation for each brother using the fact that they all spent the same amount, which we'll call 'x'. So for Justin, (1/4) * Justin's savings = x, for Jared, (1/3) * Jared's savings = x, and for Jonathan, (2/5) * Jonathan's savings = x. Since the total cost of the vase is $33, we know that 3x = $33 or x = $11. This means each brother spent $11.
Now, we can find out how much each had originally:
Justin's original savings: (1/4) of his savings is $11, so Justin had 4 * $11 = $44 before the purchase.Jared's original savings: (1/3) of his savings is $11, so Jared had 3 * $11 = $33 before the purchase.Jonathan's original savings: (2/5) of his savings is $11, so Jonathan had 5/2 * $11 = $27.50 before the purchase.What is the constant of variation?
