Paul is looking at two vacation packages while planning a trip to Cancun, Mexico. In the first vacation package, round-trip airfare costs $799, and it costs $139 per night to stay at the resort. In the second vacation package, it costs $587 per night to stay in the resort and $285 for round-trip airfare. Let x represent the number of nights spent at the resort, and let y represent the total cost of the trip. Which system of equations could be used to find how many nights Paul needs to stay at either resort so that both vacation packages have the same cost? A. B. C. D.
Answers
Answer:
y = 139x + $ 799
y = 587x + $ 285
Step-by-step explanation:
Let x represent the number of days spent at the resort and y represent the total cost.
for the first option
y = 139x + $799 since $ 139 is the amount per night at the resort, $139x must be the cost for x number of days
y = 587x + $285 similarly x number of days should equal $587x

Answers
A. Mr. Babe made a commission of $14.85
B. He makes $15.75 per hour after the raise.
Step-by-step explanation:
A. While he worked there, Mr. Babe earned 3% on how much he sells. If he sold $495 couch, how much commission did he make?
Worth of sold couch = $495
Commission = 3%
Amount of commission = 3% of total worth sold
Amount of commission = [tex]\frac{3}{100}*495[/tex]
Amount of commission = [tex]\frac{1485}{100}=\$14.85[/tex]
Mr. Babe made a commission of $14.85
B. On top of his commission, Mr. Babe made $15 per hour. He eventually got a raise with an increase of 5% per hour. After the raise, how much did he make per hour?
Amount earned per hour = $15
Increase = 5%
As the increment is on per hour amount, therefore,
Amount of increase = 5% of per hour amount
Amount of increase = [tex]\frac{5}{100}*15=\frac{75}{100} = \$0.75[/tex]
New amount per hour = Per hour amount + amount of increase
New amount per hour = 15+0.75 = $15.75
He makes $15.75 per hour after the raise.

Step-by-step explanation:
Given that [tex]g(x) = \frac{x + 1}{x - 2}[/tex] and h(x) = 4 - x
Now, if y = f(x) and y = g(x) then the composite function (f∘g)(x) is given by f[g(x)].

John weighs three times as much as Karen. Two times John’s weight plus Karen’s weight is 875 pounds. How much does John weigh? How much does Karen weigh?
Answers
Answer: Karen's weight = 125 pounds
Step-by-step explanation:
Let Karen's weight be x , this means that John's weight is 3x.
Two times John’s weight = 2(3x)
Two times John’s weight plus Karen’s weight is 875 pounds implies;
2(3x) + x = 875
6x + x = 875
7x = 875
divide through by 7
x = 125
Therefore Karen's weight = 125 pounds
John's weight = 3 x 125 = 375 pounds
Answer:
John weighs 375 pounds, and Karen weighs 125 pounds.
Step-by-step explanation:
The best way to solve this question is to assign the weights to variables.
Let's give variable j to John's weight and k to Karen's.
If John weighs 3 times as much as Karen, j=3k.
If 2x John's weight plus 1x Karen's weight = 875, then 2j + k = 875,
which can also be written as 6k + k = 875 since we established that j=3k and 2*3=6.
Now all we need to do to find k is solve the equation:
6k + k = 875 combine common factors
7k = 875 divide both sides by 7
k = 875/7
k = 125
Now that we know Karen's weight, we can find John's weight by using j=3k.
Plug the now known value of k in:
j=3k
j=3(125)
j=375
Now you have your pair:
j=375, k = 125.

a bedroom measures 13.62 feet long and 11.5 feet wide. what is the most accurate measure of the area of the bedroom, in square feet?
Answers
Answer:
156.63 Square feet
Step-by-step explanation:
Final answer:
The area of a bedroom that is 13.62 feet by 11.5 feet is 156.63 square feet, found by multiplying the length by the width.
Explanation:
The most accurate measure of the area of a bedroom that measures 13.62 feet long and 11.5 feet wide is calculated by multiplying the length by the width. The formula for the area of a rectangle is:
Area = length × width
Thus, the area is:
Area = 13.62 feet × 11.5 feet = 156.63 square feet
This calculation ensures that you have the most accurate measure of the square footage necessary, for example, if you are planning to replace the carpet or perform other renovations that require an accurate measure of the room's floor space.

Step-by-step explanation:
we have
[tex]25x^{2}+4y^{2}-50x-75=0[/tex]
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
[tex](25x^{2}-50x)+4y^{2}=75[/tex]
Factor the leading coefficient of each expression
[tex]25(x^{2}-2x)+4y^{2}=75[/tex]
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
[tex]25(x^{2}-2x+1)+4y^{2}=75+25[/tex]
[tex]25(x^{2}-2x+1)+4y^{2}=100[/tex]
Rewrite as perfect squares
[tex]25(x-1)^{2}+4y^{2}=100[/tex]
Divide both sides by the constant term to place the equation in standard form
[tex]\frac{25(x-1)^{2}}{100}+\frac{4y^{2}}{100}=\frac{100}{100}[/tex]
Simplify

for events A and B, P(A)= 3/14 and P(B)= 1/5. Also, P(A and B)= 3/65. Are A and B independent events?
Answers
No, A and B are not independent events
Step-by-step explanation:
Let us study the meaning independent probability
Two events are independent if the result of the second event is not affected by the result of the first eventIf A and B are independent events, the probability of both events is the product of the probabilities of the both events P (A and B) = P(A) · P(B)∵ P(A) = [tex]\frac{3}{14}[/tex]
∵ P(B) = [tex]\frac{1}{5}[/tex]
∴ P(A) . P(B) = [tex]\frac{3}{14}[/tex] × [tex]\frac{1}{5}[/tex]
∴ P(A) . P(B) = [tex]\frac{3(1)}{14(5)}[/tex]
∴ P(A) . P(B) = [tex]\frac{3}{70}[/tex]
∵ P(A and B) = [tex]\frac{3}{65}[/tex]
∵ P(A) . P(B) = [tex]\frac{3}{70}[/tex]
- The two answers are not equal
∴ P (A and B) ≠ P(A) · P(B)
- In independent events P (A and B) = P(A) · P(B)
∴ A and B are not independent events
No, A and B are not independent events

Events A and B are not independent.
The events A and B are independent given that P(A) = 3/14, P(B) = 1/5, and P(A AND B) = 3/65. To determine if two events are independent, the product of their individual probabilities, P(A) and P(B), should equal the probability of both events occurring together, P(A and B).
Let's calculate this:
P(A) × P(B) = (3/14) × (1/5) = 3/70
Since P(A AND B) = 3/65, we compare it to the calculated product of P(A)P(B).
P(A AND B) is not equal to P(A)P(B). Therefore, events A and B are not independent because their joint probability is not the product of their individual probabilities.
is √ 4/9 a rational number
Answers
Answer:
yes
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
Recall that a rational number is a number that results from dividing 2 integers
I'm not sure if your question refers to (√4) / 9 or √(4/9), but either way both are rational numbers:
If (√4) / 9, Then,
(√4) / 9
= 2/9
Since both 2 and 9 are integers, then 2/9 is a rational number
If √(4 / 9), Then,
√(4 / 9)
= √4 / √9
= 2/3
Since both 2 and 3 are integers, then 2/3 is also a rational number
You worked the following hours this week: Monday 8 AM to PM, Tuesday 9 AM to 3 PM, Thursday 8:30 AM to 2:15 PM.
You get a 30-minute unpaid lunch break every work day. How many hours will you be paid for this week?
Answers
To calculate the total hours you will be paid for this week, subtract the total lunch break time from the total working hours. Therefore, the total hours you will be paid for this week is 19 hours and 45 minutes.
Explanation:To calculate the number of hours you will be paid for this week, you need to subtract the total lunch break time from the total working hours.
On Monday, you worked from 8 AM to PM, which is 10 hours.
On Tuesday, you worked from 9 AM to 3 PM, which is 6 hours.
On Thursday, you worked from 8:30 AM to 2:15 PM, which is 5 hours and 45 minutes.
Overall, your total working hours for the week are 10 + 6 + 5 hours and 45 minutes.
Each day you have a 30-minute unpaid lunch break, so for the entire week you would have 4 lunch breaks x 30 minutes = 2 hours taken for lunch breaks.
Therefore, the total hours you will be paid for this week are 10 + 6 + 5 hours and 45 minutes - 2 hours = 19 hours and 45 minutes.

a 45-45-90 right triangle is formed when a ____ is cut in half
Answers
A 45-45-90 right triangle is formed when a square is cut in half diagonally. This forms two such right triangles, where the sides are in a specific ratio, with the length of the hypotenuse being root 2 times the length of each leg.
Explanation:A 45-45-90 right triangle is formed when a square is cut in half. This is because when you draw a diagonal on a square, the angles it forms with the sides are all 45 degrees, and the angles at the vertices remain 90 degrees. Therefore, it forms two 45-45-90 right triangles.
In a 45-45-90 triangle, the sides are in a specific ratio. The length of the hypotenuse is root 2 times the length of each leg, which are equal in measure because it is an isosceles triangle. These properties are unique to 45-45-90 right triangles.

covered another half of a mile. If x represents Lindsey's distance, in miles, from the campsite at 2:00p.m., what function could be used to
represent the area of the triangular region formed by the girls' locations and the campsite at 2:30 p.m.?
Answers
Answer:
A. f(x)=x^2+x+0.25
Step-by-step explanation:
If x represents Lindsey's distance at 2:00 PM, then 2x represents Kara's distance at 2:00 PM because she walked twice as far as Lindsey. Then adding on the values we got for 2:30 PM, we get that Kara walked a distance of 2x+1 and Lindsey walked a distance of x+0.5 at the time of 2:30 PM. Now, we know that they have formed a right triangle because we are given the directions they walked in; east and north. This allows us to use a formula for the area of a right triangle: 1/2(L x W). Plugging in our values, we get...
1/2(2x+1)(x+0.5)

Now applying the algebraic sum to the terms on the right hand side of the equation
[tex]5a^2=125[/tex]
[tex]a^2=\frac{125}{5}[/tex]
Now applying the division rule
[tex]a^2=25[/tex]
Therefore [tex]a=\pm 5[/tex]
Therefore option c) is correct
ie, [tex]a=\pm 5[/tex].
Which of the following is not a way to determine if a relation is a function?
A.
Use the vertical line test on a graph of the relation.
B.
Check to see if each input maps to only one output.
C.
There should be no duplicated x-coordinates in the ordered pair set.
D.
Determine if the relations’ graph forms a line.
Answers
D. Determine if the relations’ graph forms a line.
Step-by-step explanation:
A function is a relation if the input values lead to only one output value.The input values, normally x values make up the domain, where as the output values form the domain.A function is a relation where the input values are associated with a single output.The vertical test is used to determine if a curve is a function.The line graph should only hit a single point on the curve.
