Answer:
Disagree
radius = 7 m
diameter = 14 m
Step-by-step explanation:
Formula
[tex]\sf Area\:of\:a\:circle=\pi r^2[/tex]
Given:
area = 153.88 m²Substitute given value into the formula and solve for r:
[tex]\sf \implies \pi r^2=153.88[/tex]
[tex]\sf \implies r^2=\dfrac{153.88}{\pi}[/tex]
[tex]\sf \implies r=\sqrt{\dfrac{153.88}{\pi}}[/tex]
[tex]\sf \implies r=6.998680253[/tex]
Therefore r ≈ 7 m
So I disagree with Nysean, as from my calculations, the approximate radius of the merry-go-round is 7 m.
Diameter = 2r
⇒ diameter of merry-go-round = 2 x 7 = 14m
So Nysean has actually given the approximate measure of the diameter rather than the radius.

Julie wants to randomly choose two out of three friends, Margarite, Anita, and Sasha, to go with her to a
concert. In which method does one of Julie's friends have more than a fair chance of being chosen?
Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.
There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.
Describing a method which can be used to provide more than a fair chance of selection is as follows:
Julie has 3 friends, so make the total number of slips say n
where n is not a multiple of 3.
If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.
Consider n=5
She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.
Thus, this method may result in more chance of selection of one over other.

According to the question,
Time taken by Jesse to run 1 mile = 7 minutes
Also,
Time taken by Jesse to run 1 mile = 2½ minutes + Michael's time [tex]\;[/tex]
Now, we can say that :
⇒ 7 minutes = 2½ minutes + Michael's time
⇒ (7 - 2½) minutes = Michael's time
⇒ (7 - 5/2) minutes = Michael's time
⇒ (14 - 5)/2 minutes = Michael's time
⇒ 9/2 minutes = Michael's time
⇒ 4½ minutes = Michael's time [Answer]
Step-by-step explanation:
Question:-In track practice, Jesse ran a mile in 7 minutes. His mile time was2.5 minutes faster than Michael's time. Write and solve an equation to calculate Michael's mile time.
Solution
Jessie time 7 minute
Michael’s time is 2.5 times slower
Divide 7 minutes by 2.5 to get answer
Jesse = 7
Michael = 2.5 X
7 = 2.5 X
7/2.5 X = 17.5 to check answer divide 17.5 by the 2.5, your answer is 7.
Or if it was 2.5 more
we subtract 2.5 from 7
=> 7 - 2.5
=> 4.5
=> 4 ½

Hal has just graduated from four years of college. for the last two years, he took out a stafford loan to pay for his tuition. each loan had a duration of ten years and interest compounded monthly, and hal will pay each of them back by making monthly payments, starting as he graduates. hal’s loans are detailed in the table below. year loan amount ($) interest rate (%) subsidized? junior 4,048 5.9 n senior 5,295 7.6 y once all of his loans are paid off, what will hal’s total lifetime cost be? round all dollar values to the nearest cent. a. $9,023.28 b. $8,467.20 c. $11,498.40 d. $13,615.20
Hal's total lifetime cost will be $13,615.20.
Data and Calculations
Table detailing the Loans
1: Year Junior Senior
2: Loan Amount ($) 4,048 5,295
3: Interest Rate (%) 5.9% 7.6%
4: Subsidized? No Yes
5: Future value 4,539.76 5,295
6: Total repayment $6,020.76 $7,575.51
Total lifetime cost = $ 13,596.27 ($6,020.76 + $7,575.51)
What is the future value of the loan?
The future value of the loan is determined based on no subsidy and interest rate compounded for two years for the Junior Loan.
Junior loan Amount after two years = $4,539.76
Loan Term = 10 years
Interest Rate = 5.9%
Compound Monthly (APR) Pay Back Every Month
Therefore, Payment Every Month $50.17
Total of 120 Payments $6,020.76
Total Interest $1,481.00
Loan Amount = $5,295
Loan Term = 10 years
Interest Rate = 7.6%
Compound Monthly (APR)
Pay Back Every Month
Therefore, a Payment Every Month of $63.13
Total of 120 Payments $7,575.51
Total Interest $2,280.51

Which is the equation of a circle whose center is at the origin and that passes through the point (3, 5)?
Answer:
x² + y² = 34
Formula:
(x - h)² + (y - k)² = r² where (h, k) is the centerHere find the radius using distance formula: → origin : (0, 0)
√(x2-x1)²+(y2-y1)²√(3-0)²+(5-0)²√9+25√34Thus the equation of circle:
(x - 0)² + (y - 0)² = (√34)²(x - 0)² + (y - 0)² = 34x² + y² = 34Answer:
H. [tex]x^2+y^2=34[/tex]
Step-by-step explanation:
Equation of a circle (in standard form)
[tex](x-h)^2+(y-k)^2=r^2[/tex]
(where (h, k) is the center and r is the radius of the circle)
Given center = (0, 0):
[tex]\implies (x-0)^2+(y-0)^2=r^2[/tex]
[tex]\implies x^2+y^2=r^2[/tex]
As the circle passes through point (3, 5):
[tex]\implies 3^2+5^2=r^2[/tex]

Use the function f(x) = x2 − 6x 3 and the graph of g(x) to determine the difference between the maximum value of g(x) and the minimum value of f(x). a parabola that opens down and passes through 0 comma 3, 3 comma 12, and 5 comma 8 3 6 12 18
A function assigns values. The difference between the maximum value of g(x) and the minimum value of f(x) is 18.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Since the maximum of the parabola function g(x) will lie at its vertex, therefore, the maximum will be at (3,12). Now, if we try to find the minimum of the function f(x). We need to plot the function on the graph as shown below.
As the minimum of the function f(x) will lie at the vertex of the parabola function, therefore the minimum of the function f(x) will lie at (3,-6).
If we try to find the difference between the maximum value of g(x) and the minimum value of f(x), then we will get,
[tex]\rm Difference=12-(-6)=18[/tex]
Thus, the difference between the maximum value of g(x) and the minimum value of f(x) is 18.
