The area of a quarter circle is 0.785 square kilometers. What is the quarter circle's perimeter?
To find the perimeter of the quarter circle, the radius is first calculated using the area, and then the perimeter formula for a circle is applied, adjusting the final calculation to include the straight edges of the quarter circle.
The student has provided the area of a quarter circle and is seeking to find its perimeter. The area of the full circle can be found by multiplying the quarter circle area by 4, yielding an area of 3.14 square kilometers (since the area of a quarter circle is 0.785 square kilometers). Using the formula for the area of a circle, A = πr², we can solve for the radius (r).
Let's calculate the radius of the circle:
A = πr² = 3.14 km²r² = A/πr² = (3.14)/(3.1415927)r = 1 km (Here we're considering π to be approximately 3.1415927)Now, the perimeter (or circumference) of the full circle is given by the formula P = 2πr. For a quarter circle, the perimeter includes the arc of the quarter circle and the two radii.
The perimeter of the quarter circle is thus:
P = (1/4) × 2πr + 2rP = (1/4) × 2 × 3.1415927 × 1 km + 2 × 1 kmP = 1.57079635 km + 2 kmP = 3.57079635 kmBut since we know the measurements are to a certain precision, we must adjust our answer accordingly:
The final perimeter of the quarter circle, rounded to an appropriate number of significant figures based on the original measurement given, is approximately 3.57 km.

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.

If the triangle ABC is similar to the triangle DEF, estimate the area of triangle ABC if the area of the triangle DEF is 90
The area of triangle ABC, given that it is similar to triangle DEF with an area of 90, cannot be estimated without the ratio of corresponding sides. Areas of similar triangles are proportional to the square of the ratio of their corresponding sides.
Explanation:To estimate the area of triangle ABC given that triangle ABC is similar to triangle DEF, and the area of triangle DEF is 90, we first need to understand that the areas of similar triangles are proportional to the square of the ratio of their corresponding sides. However, without knowing the specific ratio of the corresponding sides of triangles ABC and DEF, we cannot calculate the exact area of triangle ABC.
For example, if we knew that every side of triangle ABC was twice as long as the corresponding sides of triangle DEF, the area of triangle ABC would be 4 times the area of triangle DEF, because the area is proportional to the square of the side lengths (2 squared is 4). In this case, if the area of DEF is 90, then the area of ABC would be 90 × 4 = 360.
Without the ratio of the sides, we can't directly calculate the area of triangle ABC from the area of triangle DEF. The relationship between similar triangles and their areas illustrates an important geometric principle, but requires specific information about the ratio of corresponding linear dimensions to make an estimation.

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.

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.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.

Write a function in terms of t that represents the situation.
Your starting annual salary of $35,000 increases by
4% each year.
With instructions on how you did it please!!!
To represent the situation, the function can be written as f(t) = 35000 × (1 + 0.04)^t, where t represents the number of years into the future.
Explanation:To write a function in terms of t that represents the situation, we can start with the initial salary of $35,000 and then calculate the annual increase using the 4% growth rate.
We need to multiply the current salary by (1 + 0.04) to get the new salary for each year. The function can be written as:
f(t) = 35000 × (1 + 0.04)^t
Here, t represents the number of years into the future from the initial starting point.
For example, if you want to find the salary after 3 years, you can plug in t = 3 into the function.
A function that represents your annual salary starting at $35,000 and increasing by 4% each year,
[tex]S(t) = 35000 * (1 + 0.04)^t[/tex], where t is the number of years.
To create a function that represents your annual salary starting at $35,000 and increasing by 4% each year,
we use the formula for exponential growth,
[tex]final amount = initial amount * (1 + growth rate)^t^i^m^e.[/tex]
Given that your initial salary is $35,000 and the growth rate is 4% (or 0.04),
let's define the function S(t) where S represents your salary and t represents the number of years:
[tex]S(t) = 35000 * (1 + 0.04)^t[/tex]
the initial salary=$35,000.
Convert the percentage increase to a decimal,
4% becomes 0.04.
Set up the function using the formula for exponential growth,
which is initial amount multiplied by [tex](1 + growth rate) ^t[/tex]
Thus, for any year t, the function [tex]S(t) = 35000 * (1 + 0.04)^t[/tex] calculates your annual salary.
