Robert ate lunch at 11:am. He ate a snack4and a half hours later. What time did he eat his snack
Answers
If Robert ate lunch at 11:am and he ate a snack 4and a half hours later, Robert ate his snack at 3:30 pm
To find out what time Robert ate his snack, we need to add 4 and a half hours to the time he ate lunch.
Since he ate lunch at 11:00 am, we can convert this time to 24-hour format by adding 12 hours to get 11:00 + 12:00 = 23:00.
Next, we add 4 and a half hours to 23:00 by converting the half hour to minutes and adding it to the minutes portion of the time:
23:00 + 4 hours + 30 minutes = 27:30
However, since there are only 24 hours in a day, we need to convert this time back to 12-hour format. To do this, we subtract 12 hours from 27:30 to get 15:30.
Therefore, Robert ate his snack at 3:30 pm (or 15:30 in 24-hour format).
In summary, we added 4 and a half hours to the time Robert ate lunch, converted the resulting time to 24-hour format, subtracted 12 hours to account for the excess of 24 hours, and then converted the time back to 12-hour format to obtain the time Robert ate his snack.

A football pitch is 128 m long and 52 m wide.
a) What is the area of the pitch?
Answers
The area of the football pitch is 6656 square meters. We can calculate it in the following manner.
To find the area of the football pitch, we need to multiply the length by the width:
Area = Length x Width
In this case, the length is 128 m and the width is 52 m. So we can substitute these values into the formula:
Area = 128 m x 52 m
Area= 6656 square meters.
So, the area of the football pitch is 6656 square meters.

You have a 12-year-old daughter and want to start a savings plan for her education. An insurance company promises to pay 1% interest per month for the next 10 years. How much money should you deposit into the fund each month in order to have $60,000 to cover the cost of education?
a) $500.00
b) $285.00
c) $600.00
d) $261.00
e) ____
Answers
To accumulate $60,000 in 10 years with a monthly interest rate of 1%, you would need to deposit approximately $261.00 per month into the savings fund.
To calculate the monthly deposit needed, we can use the future value of an ordinary annuity formula:
\(FV = P [(1 + r)^n - 1] / r\)
Where:
FV is the desired future value ($60,000)
P is the monthly deposit
r is the monthly interest rate (1% or 0.01)
n is the number of months (10 years * 12 months/year = 120 months)
Rearranging the formula to solve for P, we have:
\(P = FV (r / [(1 + r)^n - 1])\)
Substituting the given values into the formula, we get:
P = $60,000 (0.01 / [\((1 + 0.01)^{120}\) - 1])
P ≈ $261.00

what is the distance of the hyperplane (5 3x1 4x2 = 0) to the origin?
Answers
The distance between the hyperplane (5 + 3x1 + 4x2 = 0) and the origin is 1.
To find the distance between a hyperplane and the origin, we can use the formula for the distance between a point and a plane.
In this case, the hyperplane is defined by the equation 5 + 3x1 + 4x2 = 0.
To find the distance between the hyperplane and the origin, we can substitute the coordinates of the origin (0, 0) into the equation of the hyperplane and calculate the absolute value of the result:
Distance = |5 + 3(0) + 4(0)| / √(3^2 + 4^2)
= |5| / √(9 + 16)
= 5 / √25

For this experiment you have been randomly assigned to a group consisting of you and one other person. You do not know now, nor will you ever know, who this other person is. For this experiment all you have to do is distribute your 10 points into two accounts. One account called KEEP and one account called GIVE. The GIVE account is a group account between you and your group member. For every point that you (or your group member) put in the GIVE account, I will add to it 50% more points and then redistribute these points evenly to you and your group member. The sum of the points you put in KEEP and GIVE must equal the total 10 points. Any points you put in the KEEP account are kept by you and are part of your score on this experiment. Your score on the experiment is the sum of the points from your KEEP account and any amount you get from the GIVE account. For example, suppose that two people are grouped together. Person A and Person B. If A designates 5 points in KEEP and 5 points in GIVE and person B designates 10 points to KEEP and 0 points to GIVE then each person’s experiment grade is calculated in this manner: Person A’s experiment grade = (A’s KEEP) + 1.5(Sum of the two GIVE accounts)/2 = 5 +(1.5)(0+5)/2= 5 + 3.75 = 8.75. Person A’s score then is 8.75 out of 10. Person B’s experiment grade = (B’s KEEP) + 1.5(Sum of the two GIVE accounts)/2 = 10 +(1.5)(0+5)/2 = 10 + 3.75. Person B’s score then is 13.75 out of 10. (you can think of any points over 10 as extra credit) In this module’s activity you were asked to make a decision about how to invest your resources (points). This activity is a classic strategic game where the good of the individual is at odds with the good for the group. These problems are pervasive in risk management. For example, a physician who is trained to treat diseases may be reluctant to discuss alternative treatments with a patient when the physician is sure that a specific treatment is the only truly viable treatment. Nonetheless, you have learned in this course that physicians (or an agent of the physician) must have this discussion and bow to the will of the patient even if, in the physician’s judgment, the patient chooses an alternative treatment which is likely to be superfluous. In this way, informed consent and patient education are nuisances to the physician but are very important to protect the group (maybe a hospital or surgical group) from liability. In light of recent events another example is warranted. Individuals may choose to not get vaccinated since they do not want to bear the risk of any possible adverse side-effects of a vaccine. This is perfectly reasonable to do so. The problem arises when large groups of people choose to not get vaccinated thus making the impact of the disease relatively larger than need be if everyone would choose to take a vaccine (remember our first cost-benefit experiment). This implies that individual’s rights to choose not to vaccinate are at odds with what is good for the group of individuals. These types of problems are common in risk management. Discussion: (If you post your answers to each of the four questions below before the deadline, you will get the full ten points for the discussion. The questions do not need to be answered mathematically or with a calculation. If you feel the need to use mathematics to make a calculation, then you are free to do so but the questions are merely asking you for a number and how you arrived at that number. If you do not do any calculations to arrive at the number, just say how you arrived at the number. (There are no incorrect answers.) 1. In this activity how did you arrive at your decision on the keep-give split? 2. What is the best outcome of this situation for you? 3. What is the best outcome of this situation for the group? 4. Can you see any parallels with this game and how risk management strategies work? Explain.
Answers
1. I based my decision on allocating points to maximize my own score, while also considering the potential benefits of contributing to the group fund.
2. The best outcome for me would be allocating the minimum points required to the GIVE account, while putting the majority in the KEEP account. This would ensure I receive the most points for myself.
3. The best outcome for the group would be if both participants maximized their contributions to the GIVE account. This would create the largest group fund, resulting in the most redistributed points and highest average score.
4. There are parallels with risk management strategies. Individuals may act in their own self-interest, but a larger group benefit could be achieved if more participants contributed to "group" risk management strategies like vaccination, safety protocols, insurance policies, etc. However, some individuals may free ride on others' contributions while benefiting from the overall results. Incentivizing group participation can help align individual and group interests.

Answers
The inverse of the statement is "If a number does not have exactly two distinct factors, then the number is not prime." Thus Option 2 is the answer.
When a conditional statement is reversed, the hypothesis and conclusion are both negated. The hypothesis in the original statement is "a number with exactly two distinct factors," while the conclusion is "is prime."
To make the inverse, we negate both sections. "A number does not have exactly two distinct factors" is the antonym of "A number that has exactly two distinct factors." "Is not prime" is the opposite of "is prime."
As a result, the inverse statement is "If a number does not have exactly two distinct factors, then the number is not prime."
It's crucial to remember that a statement's inverse could or might not be accurate. In this instance, the inverse is true since the definition of a prime number is incompatible with the fact that a number has more than two components if it has more than exactly two different factors.

An original oil painting measures 55" x 55". The artist wants to produce prints that are 2.5 times smaller than the original painting. What will be the side length, in inches, of the prints?
Answers
Answer:
The side length of the prints is approximately 34.785 inches.
Step-by-step explanation:
First, we have to calculate the area of the original oil painting (\(A\)), measured in square inches, by the following formula:
\(A = l^{2}\) (1)
Where \(l\) is the length of the side, measured in inches.
And the length of the miniature is determine by means of reduction factor (\(k\)), with no unit:
\(\frac{A}{k} = l'^{2}\) (2)
If we know that \(l = 55\,in\) and \(k = 2.5\), then the side length of the miniatures is:
\(l' = \sqrt{\frac{l^{2}}{k} }\)
\(l' = \frac{l}{\sqrt{k}}\)
\(l' = \frac{55\,in}{\sqrt{2.5}}\)
\(l' \approx 34.785\,in\)
The side length of the prints is approximately 34.785 inches.

Explain about the angles?Angles are measurements that can be expressed in radians or degrees and are formed by two lines as well as segments. The angles that are inscribed are those that are inside a circle that is made up of chords, a radius, a diameter, etc. A number of characteristics, including the theorem about inscribed angles generated by chords, enable us to solve mathematical issues involving circles.For the given question:
∠A = 20°
We know that, tangents drawn from the same external points forms the equal tangents on circle.
AB = AD
And, ∠A is also bisected by the line AC.
Thus,
In ΔABC, (sum of angles is 180)
10 + ∠B + ∠ACB = 180
Tangent form 90 degrees with radius.
10 + 90 + ∠ACB = 180
∠ACB = 180 - 100
∠ACB = 180

A satellite is to be put into an elliptical orbit around a moon as shown below. A vertical ellipse is shown surrounding a spherical object labeled, moon. The moon is a sphere with radius of 1000 km. Determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 953 km to 466 km.
Answers
Answer:
The correct equation will be "\(\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1\)".
Step-by-step explanation:
In the above question, the figure is missing. Please find below the attachment of the figure.
According to the question,
Radius of a moon,
r = 1000 km
The max. distance from moon's surface to the satellite,
a = 953 km
The min. distance from moon's surface to the satellite,
b = 466 km
Now,
As per the question or the diagram,
⇒ \(a_1=a+r\)
\(=953+1000\)
\(=1953 \ km\)
⇒ \(b_1=b+r\)
\(=466+1000\)
\(=1466 \ km\)
hence,
The equation of ellipse will be:
⇒ \(\frac{x^2}{b_1^2} +\frac{y^2}{a_1^2} =1\)
On substituting all the values, we get
⇒ \(\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1\)
