To find the initial number of chocolates Jenny had, we solve the equation (x - 2)/2 = 6, which results in x = 14. Therefore, Jenny had 14 chocolates initially.
The question asks to determine how many chocolates Jenny had in the beginning if she eats two and gives half of the remainder to Lisa, who ends up with six chocolates. To solve this, we let x represent the initial number of chocolates Jenny had. After eating two chocolates, Jenny has x - 2 left. She gives half of this remainder to Lisa, which means Lisa receives (x - 2)/2 chocolates. Since Lisa has six chocolates, we set up the equation (x - 2)/2 = 6. Solving this gives us x - 2 = 12 and therefore, x = 14. Hence, Jenny had 14 chocolates in the beginning. The correct answer is option C. 14.

The equation that represents the cost y (in dollars) of renting a jet ski for x hours is y = -87.50x + 525.
Explanation:The equation that represents the cost y (in dollars) of renting a jet ski for x hours can be found by analyzing the given information. Let's break it down step by step:
We are given that it costs $175 to rent a jet ski for 2 hours. This means the cost per hour is $175 / 2 = $87.50.We are also given that it costs $300 to rent a jet ski for 4 hours. This means the cost per hour is $300 / 4 = $75.Based on these two data points, we can see that as the number of hours increases, the cost per hour decreases. Therefore, we can infer that the cost of renting a jet ski is a linear function of the number of hours.Now, let's use the point-slope form of a linear equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.Therefore, the equation that represents the cost y (in dollars) of renting a jet ski for x hours is y = -87.50x + 525.

Point M is the midpoint of AB . AM= 3x+3, and AB=8x−6
What is the length of AM?
The answer is 21 but i don't know the steps to get it. HELP
The length of AM is:
21 units.
Step-by-step explanation:Point M is the midpoint of AB.
AM= 3x+3, and AB=8x−6
Since, the midpoint divides the line segment into two equal parts i.e. it bisects the line segment.
Hence, we have:
AM+MB=AB
Also, AM=MB
Hence, we have:
[tex]3x+3+3x+3=8x-6[/tex]
on combining the like terms in the left hand side of the equation we have:
[tex]3x+3x+3+3=8x-6\\\\6x+6=8x-6[/tex]
Now, on subtracting both side of the equation by 6x we have:
[tex]6=8x-6-6x\\\\6=8x-6x-6\\\\6=2x-6[/tex]
on adding 6 on both side of the equation we have:
[tex]6+6=2x\\\\12=2x\\\\2x=12\\\\x=\dfrac{12}{2}\\\\x=6[/tex]

A bottle of soft drink is two thirds full. Jack drinks one quarter of the remaining soft drink. How full is the bottle now
Charli,
First find what 1/4 of 2/3 is.
1/4 of 2/3 = 1/6
(That is 1/4 times 2/3 = 1/6)
So, the bottle was 2/3 full, it is now ...
2/3 - 1/6
=4/6 - 1/6
= 3/6 or 1/2 full.
We know that the bottle of soft drink has a remaining volume which is 2 / 3 of the original.
Since Jack drank 1 / 4 of the remaining volume, hence only 3 / 4 now finally remains, the total is:
(2 / 3) * (3 / 4) = 6 / 12 = 1 / 2
Hence the bottle is now one half full

A couch, a love seat, and a chair cost $1565. The couch costs twice as much as the chair, and the live seat costs $400 more than the couch. Find the cost of the love seat, the couch, and the chair.
To find the cost of the love seat, couch, and chair, set up a system of equations and solve for the variables.
Explanation:To find the cost of the love seat, the couch, and the chair, we need to set up a system of equations based on the given information. Let's represent the cost of the chair as x. Since the couch costs twice as much as the chair, its cost will be 2x. The love seat costs $400 more than the couch, so its cost will be 2x + $400. The sum of the costs of all three pieces of furniture is $1565. Using these equations, we can solve for x, and then find the costs of the love seat, the couch, and the chair.
Equations:
x + 2x + (2x + $400) = $15655x + $400 = $15655x = $1165x = $233Cost of the Chair: $233
Cost of the Couch: 2x = 2($233) = $466

Although the actual amount varies by season and time of day, the average volume of water that flows over the falls each second is 5.25.2 times ×10 Superscript 5105 gallons. How much water flows over the falls in an hour? Write the result in scientific notation. (Hint: 1 hour equals 3600 seconds)
The amount of water flowing each second is:
rate = 5.2 x 10^5 gallons / second
Since we know that:
1 hour = 3600 seconds
Therefore:
rate = (5.2 x 10^5 gallons / second) * (3600 seconds / hour)
rate = 1.872 x 10^9 gallons / hour
Final answer:
The average volume of water that flows over the falls in an hour is 1.89 x 10^9 gallons/hour.
Explanation:
To calculate the amount of water that flows over the falls in an hour, we need to convert the given flow rate from gallons per second to gallons per hour.
There are 3600 seconds in an hour, so we can multiply the flow rate (5.25 x 105 gallons per second) by 3600 to find the flow rate in gallons per hour.
The calculation would be: 5.25 x 105 gallons/s * 3600s/hour = 1.89 x 109 gallons/hour.
The result, in scientific notation, is 1.89 x 109 gallons/hour.

Given F= 9/5C+32, the conversion formula for Fahrenheit to Celsius, solve for C
Answer:
The required equation is [tex]C=\frac{5}{9}(F-32)[/tex]
Step-by-step explanation:
Consider the provided equation.
[tex]F= \frac{9}{5}C+32[/tex]
Solve the formula for C.
Subtract 32 from both sides.
[tex]F-32= \frac{9}{5}C+32-32[/tex]
[tex]F-32= \frac{9}{5}C[/tex]
Multiply both the sides by 5/9.
[tex]\frac{5}{9}(F-32)= \frac{9}{5}C\times \frac{5}{9}[/tex]
[tex]C=\frac{5}{9}(F-32)[/tex]
Hence the required equation is [tex]C=\frac{5}{9}(F-32)[/tex]
The formula to convert Fahrenheit to Celsius is C = 5/9( F - 32 ).
How to solve for a variable in an equation?Given the equation in the question:
F = (9/5)C + 32
To solve for C (Celsius) in the conversion formula F = (9/5)C + 32, first, isolate the terms that contain C on one side of the equation.
F = (9/5)C + 32
Subtract 32 from both sides of the equation:
F - 32 = (9/5)C + 32 - 32
F - 32 = (9/5)C
Next, multiply both sides by the reciprocal of the coefficient of C: 5/9:
5/9( F - 32 ) = 5/9 × (9/5)C
5/9( F - 32 ) = C
C = 5/9( F - 32 )
Therefore, C equals C = 5/9( F - 32 ).

The table represents the height of a ball thrown up from the roof of a building, h(t), in meters, t seconds after it is thrown upward. Which statements are true? Check all that apply.
Answer:
A. The ball is at the same height as the building between 8 and 10 seconds after it is thrown.
C. The ball reaches its maximum height about 4 seconds after it is thrown
Step-by-step explanation: • The ball is at the same height as the building between 8 and 10 seconds after it is thrown. TRUE - the height is zero somewhere in that interval, hence the ball is the same height from which it was thrown, the height of the roof of the building.
• The height of the ball decreases and then increases. FALSE - at t=2, the height is greater than at t=0.
• The ball reaches its maximum height about 4 seconds after it is thrown. TRUE - the largest number in the table corresponds to t=4.
• The ball hits the ground between 8 and 10 seconds after it is thrown. FALSE - see statement 1.
• The height of the building is 81.6 meters. FALSE - the maximum height above the building is 81.6 meters. Since the ball continues its travel to a distance 225.6 meters below the roof of the building, the building is at least that high.

(c) what is the probability that diameter is within 2 mm of the mean diameter? (round your answer to three decimal places.)
a. Probability density function (pdf) of X: 0.247 for 0.20 < x < 4.25.
b. Probability that diameter exceeds 2 mm: 0.556.
c. Probability that diameter is within 2 mm of the mean diameter: 0.988.
(a) Probability density function (pdf) of X:
For a uniform distribution with A = 0.20 and B = 4.25, the pdf is constant within the range A to B and 0 elsewhere. Therefore:
f(x) = 1 / (B - A) = 1 / (4.25 - 0.20) = 1 / 4.05 ≈ 0.247 for 0.20 < x < 4.25
(b) Probability that diameter exceeds 2 mm:
P(X > 2) = (4.25 - 2) * f(x) = 2.25 * 0.247 ≈ 0.556
(c) Probability that diameter is within 2 mm of the mean diameter:
The mean of a uniform distribution is (A + B)/2 = (0.20 + 4.25)/2 = 2.225.
So, we need to find P(2.225 - 2 < X < 2.225 + 2), which is P(0.225 < X < 4.225).
P(0.225 < X < 4.225) = (4.225 - 0.225) * f(x) = 4 * 0.247 ≈ 0.988
