-4-12 percent
-0-12 percent
-0-100 percent
-4-25 percent
Water vapor is an important component of the Earth's atmosphere, and it plays a crucial role in regulating the climate. water vapor makes up about 0-4% of the Earth's atmosphere by volume . So the correct option is A.
It is a greenhouse gas, which means that it can trap heat in the atmosphere and contribute to global warming. The amount of water vapor in the atmosphere can vary depending on location, temperature, and weather conditions. On average, water vapor makes up about 0-4% of the Earth's atmosphere by volume. This may seem like a small amount, but it has a significant impact on weather patterns and climate. As temperatures rise due to climate change, the amount of water vapor in the atmosphere is expected to increase, which could have further impacts on global climate.

Back in ye olden days, cell phone companies charged for texting. A cell phone company charges 10 cents per text message if a customer sends up to 100 messages per month, 8 cents for 101-200 messages, and 6 cents for 201-300 messages. If today is the last day of the month, and you've sent 200 texts, is it worth it to send 1 more text message?
Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
If you send 1 more text, it will be worth it because you will save:
= 16 - 12.06
= $3.94
the side lenghts of a triangle are 14,15, and x units
9514 1404 393
Answer:
1 < x < 29
Step-by-step explanation:
The triangle inequality requires the sum of the two shortest sides exceed the longest side.
When x and 14 are the shortest:
x + 14 > 15
x > 1
When 14 and 15 are the shortest:
14 +15 > x
29 > x
Then the requirement for the length of x is ...
1 < x < 29
_____
Additional comment
The length of the third side of a triangle can be between the difference and sum of the two given sides.

a painter used 3/4 of a gallon of paint to cover 1/4 of the wall. How much paint does a painter need to cover a whole wall?
Answer:
Step-by-step explanation:
3 gallons because 3/4 of a gallon covers 1/4 of a wall so you multiply the amount of gallons used for a wall times 4 which is 12/4 (keep the denominator the same ) and then divide 12 by 4 which is 3 gallons
Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
The solution of the equation ( x - 7 ) × 2 = 36 is x = 25
The equation is
( x - 7 ) × 2 = 36
To solve this equation we have to rearrange the terms and do the arithmetic operations
The arithmetic operation is a branch of mathematics. The basic arithmetic operations are addition, subtraction, division and multiplication.
Move the 2 to the right hand side of the equation
x - 7 = 36 / 2
Divide the term
x - 7 = 18
Move the 7 to the right hand side of the equation
x = 18 + 7
Add the term
x = 25
Hence, the solution of the equation ( x - 7 ) × 2 = 36 is x = 25

You are to construct an appropriate statistical process control chart for the average time (in seconds) taken in the execution of a set of computerized protocols. Data was collected for 30 samples each of size 40, and the mean of all sample means was found to be 50. What is the LCL of a 3.6 control chart? The standard deviation of the sample-means was known to be 4.5 seconds.
The Lower Control Limit (LCL) of a 3.6 control chart is 44.1.
To construct an appropriate statistical process control chart for the average time taken in the execution of a set of computerized protocols, data was collected for 30 samples each of size 40, and the mean of all sample means was found to be 50. The standard deviation of the sample-means was known to be 4.5 seconds.
A control chart is a statistical tool used to differentiate between common-cause variation and assignable-cause variation in a process. Control charts are designed to detect when process performance is stable, indicating that the process is under control. When the process is in a stable state, decision-makers can make informed judgments and decisions on whether or not to change the process.
For a sample size of 40, the LCL formula for the x-bar chart is: LCL = x-bar-bar - 3.6 * σ/√n
Where: x-bar-bar is the mean of the means
σ is the standard deviation of the mean
n is the sample size
Putting the values, we have: LCL = 50 - 3.6 * 4.5/√40
LCL = 50 - 2.138
LCL = 47.862 or 44.1 (approximated to one decimal place)
Therefore, the LCL of a 3.6 control chart is 44.1.

From the question, we are to determine which table is a function
For a table of values to represent a function, the x values on the table must have exactly one y value
This in other words mean that:
The value of age can only have one corresponding height value
Using the above as a guide, we have the following:
Zelda's: Age 12 have more than one heightMaya's: Age 12 have more than one heightJason's: Age 12 have more than one heightThis means that the above results cannot be said a function.

Answer:
the answer is C 803.8 in2
Step-by-step explanation:
2/5 - 4 1/8 / (-2 1/4)
Step-by-step explanation:
let's first transform these terms into real fractions :
2/5 = 2/5
4 1/8 = (4×8 + 1)/8 = 33/8
2 1/4 = (2×4 + 1)/4 = 9/4
first we need to handle the division (remember the priorities of arithmetic operations) :
-33/8 / -9/4 = (-33×4) / (-9×8) = 33 / (9×2) = 33/18
then we have to calculate
2/5 + 33/18
to do that we have to bring both fractions to the same denominator (must be divisible by 18 and by 5, so in this case it is 5×18 = 90) :
2/5 = 2/5 × 18/18 = 36/90
33/18 = 33/18 × 5/5 = 165/90
so,
36/90 + 165/90 = 201/90 = 67/30 = 2 7/30

in your own words explain the relationship of the properties of a parrallelogram to the construction of the house above
the properties of a parallelogram can be applied to construction and design to ensure consistency, symmetry, and aesthetics in the structure.
Without a specific picture or description of the house above, I cannot provide a detailed answer on how the properties of a parallelogram relate to its construction. However, I can explain how the properties of a parallelogram relate to construction and design in general.
A parallelogram is a type of quadrilateral that has two pairs of parallel sides. The properties of a parallelogram include equal opposite sides, equal opposite angles, and parallel opposite sides. These properties can be useful in construction and design because they provide a way to ensure that certain features of a structure are consistent and parallel.
For example, in the construction of a rectangular room, the properties of a parallelogram can be used to ensure that the opposite walls are parallel and the adjacent walls are perpendicular. This can be achieved by measuring the lengths of the opposite sides and checking that they are equal, and measuring the angles between the adjacent sides and checking that they are 90 degrees. By doing so, we can ensure that the room is rectangular and has consistent dimensions.
Additionally, the properties of a parallelogram can be used to create aesthetically pleasing designs in architecture, such as the use of parallel lines and symmetry. For instance, a series of parallel arches can be used to create a visually appealing entrance to a building, and the use of parallel lines can be used to create a sense of order and balance in the design.

Express your answer to three decimal places and include the appropriate units.
The average speed of the car is 28.6 mph
Given data:
To calculate the average speed of your car, we need to determine the total distance traveled and the total time taken. Based on the information provided in the table:
Initial time: 3:00 PM
Initial mile marker: 18
Final time: 8:00 PM
Final mile marker: 161
To calculate the total distance traveled, we subtract the initial mile marker from the final mile marker:
Total distance = Final mile marker - Initial mile marker
Total distance = 161 mi - 18 mi
Total distance = 143 mi
To calculate the total time taken, we subtract the initial time from the final time:
Total time = Final time - Initial time
Total time = 8:00 PM - 3:00 PM
Total time = 5 hours
Now, calculate the average speed using the formula:
Average speed = Total distance / Total time
Average speed = 143 mi / 5 h
Average speed ≈ 28.6 mph
Hence, the average speed of your car on the road trip is approximately 28.6 mph (miles per hour).
