It would take Jack $4$ hours to mow the lawn if he works alone. Fortunately, after he mows for $2$ hours, Jill joins him. They finish mowing $90$ minutes later. How many minutes would it have taken for Jill to mow the entire lawn alone? Enter your answer as a number without units.
Answers
Answer:
12 hours
Step-by-step explanation:
In 1 hour jack mows 1/4 of the lawn
Together they mow half a lawn in 1.5 hours
Which is a whole lawn in 3 hours
in one hour together they mow 1/3 of the lawn
It takes Jill x hours to mow the lawn
in one hour Jill mows 1/x of the lawn
Working together in one hour
jack + jill = together
1/4 + 1/x = 1/3
1/x = 1/3 - 1/4
1/x = 4/12 - 3/12
1/x = 1/12
Cross multiply
12 = x
It takes Jill 12 hours to mow the lawn
The number of minutes that it would have taken for Jill to mow the entire lawn alone is 12 hours or 720 minutes.
From the information given, it will takes Jill x hours to mow the lawn. Therefore, in one hour Jill mows 1/x of the lawn
Therefore, the equation to solve the question will be:
1/4 + 1/x = 1/3
1/x = 1/3 - 1/4
1/x = 4/12 - 3/12
1/x = 1/12
Cross multiply
x = 12
Therefore, it takes Jill 12 hours to mow the lawn.

Geraldine invests $2,500 in a retirement account with a fixed annual interest rate of 9.5% compounded
every month. What will the account balance be after 15 years?
Answers
Answer:
FV= $10,342.64
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= $2,500
Interest rate (i)= 0.095/12= 0.00792
Number of periods (n)= 15*12= 180
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1 + i)^n
FV= 2,500*(1.00792^180)
FV= $10,342.64
Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and

$12 per week. How many weeks will pass before Michelle and Pierre have the same
amount of money?
Answers
Answer:
on the 5th week they would both have the same amount of money they would both have a total of 85$
Step-by-step explanation:
The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Let x be the number of the weeks and y be the total amount.
Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.
Then the equations will be
y = 5x + 60 ....1
y = 12x + 25 ....2
Subtract equation 1 from equation 2. Then we have
7x – 35 = 0
7x = 35
x = 5 weeks
Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

Determine the ratio of the note B to middle C.
Express the answer as a simple integer ratio. (Ratios will be approximate due to rounding.)
a. 4 to 3
b. 9 to 8
c. 5 to 3
d. 17 to 9
Please select the best answer from the choices provided
Answers
Answer:
D. 17 to 9
Step-by-step explanation:
I calculated it logically
Answer:
The frequency of B in the C major key can be found in the table, and it is 494 Hz.
The frequency of middle C is 262 Hz.
So the ratio of the frequency of B to middle C is:
494 Hz / 262 Hz ≈ 1.886
To express this as a simple integer ratio, we can divide both 494 and 262 by their greatest common factor, which is 2:
494 Hz / 2 = 247 Hz
262 Hz / 2 = 131 Hz
So the ratio of the frequency of B to middle C is:
247 Hz / 131 Hz = 19/10 ≈ 1.9
This ratio is closest to 2, but we need to express it as a simple integer ratio. The closest simple integer ratio is 19 to 10.
Therefore, the answer is (D) 17 to 9

A statistics student is asked to test the integrity of the spinner using a chi-square goodness-of-fit test. What is the minimum number of times the spinner should be spun to conduct this test
Answers
The minimum number of times the spinner should be spun to conduct a chi-square goodness-of-fit test is 100.
In order to use chi-square goodness-of-fit test, we must have expected frequency at least 5.
In the given table, the minimum probability is 0.05, so to fulfill the requirement of chi-square test we have to choose n such that expected frequency corresponding to 0.05 probability is at least 5.
We will do this by hit and trials.
Let n = 10
then,
expected frequency = n x p = 10 x 0.05 = 0.5 < 5
Let n = 25
then
Expected frequency = nxp = 25 x 0.05 = 1.25 < 5
Let n = 50
then
Expected frequency = nxp = 50 x 0.05 = 2.25 < 5
Let n = 100
then
Expected frequency = n x p = 100x 0.05 = 5
For n=100, expected frequency is 5. That means the spinner should be spun at least 100 times.
Hence, to conduct chi-square goodness of fit test, the spinner should be spun minimum of 100 times.
