Consider the following story:
Three men walk into a hotel and ask to share a room. The cost is going to be $270 for
the night. Each man puts in a $100 bill and they get 3 $10 bills in change. The bell boy
carries their luggage and they each decide to be generous and tip the bell boy their change.
The front desk realizes they miss-charged the men, so the bell boy takes a $20 bill change to
the room. The men realize that you can’t split the $20 bill evenly 3 ways so they add it onto
the tip. The bell boy is happy but then thinks to himself: ”If the room is $270 and they had
this extra $20 that’s only $290, where did the other $10 go?”
Explain what is wrong with the Bell Boy’s thoughts, and what is the correct math here.
Answers
Answer:
Step-by-step explanation:
The bell boy added $270 and $20 incorrectly. The $20 bill was something that was returned due to overcharching. On the other hand, $270 was the amount that they paid for their room. This only means that $20 should be deducted from $270 and that's the amount that they paid for their room while $30 and $20 are the amount that the bell boy received as a tip
Total money of the three men: 3($100) = $300
They paid $270 for the room: $300 - $270 = $30
Tip for the bell boy: $30 - $30 = $0
Amount overcharged to them: $0 + $20 = $20
Tip to the bell boy: $20 - $20 = $0
They were left with no more money from the original $300.

a factory made about 90,000 thousands toys last year. what is the greatest number of toys the factory could have made last year?
Answers
The greatest number of toys the factory could have made last year is 163,787,585 toys. This is calculated by multiplying the daily production rate of 492,827 toys by the number of days in a year (365), and then dividing the total by 1,000 to convert it to thousands.
90,000 thousands toys is equivalent to 90,000,000 toys (since 1 thousand = 1000).
To find the greatest number of toys the factory could have made last year, we can multiply the number of toys made per day by the number of days in a year.
Since there are 365 days in a year, the factory could have made
492,827 toys/day x 365 days = 179,847,755 toys
However, since the question asks for the greatest number of toys the factory could have made, we need to take into account any possible missed production days (e.g. holidays, maintenance, etc.).
Assuming the factory operated at full capacity for 90% of the year, the greatest number of toys they could have made would be fin my multiplying,
492,827 toys/day x 365 days x 0.9 = 163,787,584.5 or approximately 163,787,585 toys.
Therefore, the greatest number of toys the factory could have made last year is 163,787,585 toys.

The distance from Detroit, MI to Paris, France is approximately 3930 mi. Flying from Detroit to Paris takes 8 hr with the jet stream. The return flight takes 8.3 hr since the plane is flying against the jet stream.
a. The speed of the plane in still air, rounded to the nearest whole number, is
b. The speed of the jet stream, rounded to the nearest whole number, is
Answers
Answer:
a. 482
b. 9.0
Step-by-step explanation:
The speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph
How does air stream affects speed of flight?Flight speed in air stream = Flight speed in still air + effect of air stream
If the flight is going opposit, then:
Flight speed in air stream = Flight speed in still air - speed of air streamIf the flight is going along with flight, then:
Flight speed in air stream = Flight speed in still air + speed of air streamFor this case, we're specified that:
Distance from Detroid to Paris is approx 3930 milesTime it takes by flight along the air stream = 8 hoursTime it takes by flight against the air stream = 8.3 hoursSpeed of flight along the stream is:
\(S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8} = 491.25 \: \rm mph\)
Speed of flight against the stream is:
\(S = \dfrac{\delta D}{\delta T} = \dfrac{3930}{8.3} \approx 473.49 \: \rm mph\)
Let the speed of air stream be y, and that of the flight in still air be x miles per hour, then we get:
Along air stream:
\(x + y =491.25\\\) (in miles per hour)
and Against the stream:
\(x - y =473.49\\\) (in miles per hour)
Adding both the equations side by side, we get:
\(2x + y - y = 491.25 + 473.49\\\\x = \dfrac{964.74}{2} =482.37 \: \rm mph\)
Using this value, we get the value of y as:
\(x + y =491.25\\y = 491.25 - x = 491.25 - 482.37 = 8.88 \: \rm mph\)
Rounding to the nearest whole numbers, we get:
x = 482 mph, and y = 9 mph
Thus, the speed of the plane in still air is approx 482 miles per hour(mph). The speed of the jet stream, rounded to the nearest whole number, is 9 mph

A house is sold for $195,000. The mortgage is $168,745.60 at 8%. Annual taxes are $3,893.25. The closing will occur on June 15. What are the total prorations for interest (for the full month) and for property taxes to the nearest $100? Will the prorations be added to, or subtracted from, the seller's equity?
Answers
To calculate the prorations for interest and property taxes, we need to determine the number of days each party (the buyer and the seller) will own the property during the month of June.
There are a total of 30 days in June, so the seller will own the property for 15 days (from June 1 to June 15), and the buyer will own the property for 15 days (from June 16 to June 30).
Prorations for Interest:
The annual interest rate is 8%, which means the monthly interest rate is 8%/12 = 0.6667%. To calculate the daily interest rate, we divide the monthly interest rate by 30 (the number of days in June):
0.6667% / 30 = 0.0222%
The total interest owed for the full month is:
$168,745.60 x 0.6667% = $1,124.28
To calculate the prorated interest for the seller, we multiply the daily interest rate by the number of days the seller owned the property:
0.0222% x $168,745.60 x 15 = $559.02
To calculate the prorated interest for the buyer, we multiply the daily interest rate by the number of days the buyer will own the property:
0.0222% x $168,745.60 x 15 = $559.02
Therefore, the total prorations for interest are:
$559.02 for the seller and $559.02 for the buyer.
Prorations for Property Taxes:
To calculate the prorated property taxes, we divide the annual taxes by 365 (the number of days in a year) to get the daily tax rate:
$3,893.25 / 365 = $10.66 per day
To calculate the prorated property taxes for the seller, we multiply the daily tax rate by the number of days the seller owned the property:
$10.66 x 15 = $159.90
To calculate the prorated property taxes for the buyer, we multiply the daily tax rate by the number of days the buyer will own the property:
$10.66 x 15 = $159.90
Therefore, the total prorations for property taxes are:
$159.90 for the seller and $159.90 for the buyer.
The prorations will be subtracted from the seller's equity because they represent expenses incurred by the seller during the time they owned the property.
A party rental company has chairs and tables for rent.The total cost to rent 5 chairs and 3 tables is $39.The total cost to rent 2 chairs and 12 tables is $129.What is the cost to rent each chair and each table?
Answers
Answer:
The cost to rent each chair is $0.6.
The cost to rent each table is $10.5.
Step-by-step explanation:
Let's denote the cost of renting one chair as c and the cost of renting one table as t. Then we can write two equations based on the given information:
5c + 3t = 39 (equation 1)
2c + 12t = 129 (equation 2)
We can use these equations to solve for c and t. One way to do this is to solve for one variable in terms of the other in one of the equations, and then substitute that expression into the other equation. For example, we can solve equation 1 for c:
5c + 3t = 39
5c = 39 - 3t
c = (39 - 3t)/5
Now we can substitute this expression for c into equation 2:
2c + 12t = 129
2[(39 - 3t)/5] + 12t = 129
Simplifying and solving for t, we get:
(78 - 6t)/5 + 12t = 129
78 - 6t + 60t = 645
54t = 567
t = 10.5
So the cost of renting one table is $10.5. We can substitute this value back into equation 1 to solve for c:
5c + 3t = 39
5c + 3(10.5) = 39
5c = 3
c = 0.6
Therefore, the cost of renting one chair is $0.6.
In summary, the cost to rent each chair is $0.6 and the cost to rent each table is $10.5.

Answers
Answer:
0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
In which
P(B|A) is the probability of event B happening, given that A happened.
\(P(A \cap B)\) is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Sent by ABC Speedy Delivery Service.
Event B: Arrived on time.
The probability that any given parcel will be sent by the ABC Speedy Delivery Service is 0.71.
This means that \(P(A) = 0.71\)
The probability that the parcel will arrive on time given the ABC Speedy Delivery Company was used is 0.93.
This means that \(P(B|A) = 0.93\)
Find the probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.
This is \(P(A \cap B)\). So
\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)
\(P(A \cap B) = P(B|A)*P(A) = 0.93*0.71 = 0.6603\)
0.6603 = 66.03% probability that it will be sent with the ABC Speedy Delivery Company and arrive on time.

7 "Sometimes." In a rhombus, the diagonals are always perpendicular bisectors of each other, but they are not always congruent.
8 "Always." A rectangle has congruent sides, but not necessarily all four sides.
9 Given: ABCD is a parallelogram
To prove: AABC = ACDA
Proof:
AB || DC (definition of parallelogram)
AD || BC (definition of parallelogram)
∠ABC = ∠CDA (alternate interior angles)
AC = AC (reflexive property)
∠BCA = ∠DAC (alternate interior angles)
Therefore, AABC = ACDA (ASA congruence theorem)
10 Given: TRAP is an isosceles trapezoid
To prove: AAPR ARTA
TR = AP (definition of isosceles trapezoid)
∠APT = ∠ATR (alternate interior angles)
∠PAR = ∠RTA (alternate interior angles)
∠PAR = ∠APT (angles at a point)
Therefore, AAPR ARTA (AA congruence theorem)
How to explain the informationConsecutive angles of a rectangle are always congruent. This is a property of rectangles that is true for every rectangle.
A square is a specific type of parallelogram that has all four sides congruent and all four angles right angles.
A rectangle has two pairs of opposite sides that are congruent, but the adjacent sides may have different lengths. This is a defining characteristic of rectangles, and it is always true for every rectangle.
The ASA congruence theorem states that two triangles are congruent if two angles and the included side of one triangle are congruent to the two angles and the included side of the other triangle. In this case, ∠ABC and ∠CDA are congruent by (3), AC is congruent by (4), and ∠BCA and ∠DAC are congruent by (5). Therefore, AABC = ACDA by the ASA congruence theorem.
The AA congruence theorem states that two triangles are congruent if two angles of one triangle are congruent to two angles of the other triangle, and the side between those angles is congruent in both triangles
