When added to 2 PM, this gives us a time of 2:17 PM. Thus, Ron returned home at 2:17 PM.
Ron left his home at 7:00 AM. To determine what time he returned home, we need to add 7 hours and 35 minutes to the time he left. This can be done by adding 7 hours to the hours portion of the time and 35 minutes to the minutes portion of the time. In this case, 7 hours added to 7 AM is 2 PM, and 35 minutes added to 0 minutes is 35 minutes, so Ron returned home at 2:35 PM. To be more precise, we can convert the minutes portion of the time to a fraction of an hour, which would give us 2 hours and 35/60 of an hour or 2 hours and 0.5833 hours. When added to 2 PM, this gives us a time of 2:17 PM. Thus, Ron returned home at 2:17 PM.

Jacob and Jordan are training for track season. Jacob did 39 sit-ups in 30 seconds. Jordan did 59
sit-ups in 50 seconds. Who will likely do more sit-ups in 2 1/2 minutes? Explain.
Answer: Jacob
Step-by-step explanation:
Jacob = 39 sit-ups/30 seconds
Jordan = 59 sit-ups/50 seconds
2.5 minutes = 150 seconds
[tex]Jacob=\frac{39}{30} =\frac{195}{150}[/tex]
[tex]Jordan=\frac{59}{50}=\frac{177}{150}[/tex]
[tex]\frac{195}{150} > \frac{177}{150}[/tex]
To compare the number of sit-ups Jacob and Jordan can do in 2 1/2 minutes, we need to convert their current rates to the same unit of time. Since 2 1/2 minutes is the same as 150 seconds, we can use unit rates to find the number of sit-ups they can do per second.
Jacob's rate is 39 sit-ups in 30 seconds, so his unit rate is:
39/30 sit-ups per second
Simplifying the fraction, we get:
13/10 sit-ups per second
Jordan's rate is 59 sit-ups in 50 seconds, so his unit rate is:
59/50 sit-ups per second
Multiplying the numerator and denominator by 3, we get:
177/150 sit-ups per second
Now we can use these unit rates to estimate the number of sit-ups Jacob and Jordan can do in 2 1/2 minutes:
Jacob's estimated number of sit-ups = unit rate × time
= (13/10 sit-ups per second) × (150 seconds)
= 195 sit-ups
Jordan's estimated number of sit-ups = unit rate × time
= (177/150 sit-ups per second) × (150 seconds)
= 177 sit-ups
Based on these estimates, Jacob is likely to do more sit-ups in 2 1/2 minutes than Jordan, since he can do approximately 18 more sit-ups (195 - 177).
Therefore, Jacob is likely to do more sit-ups in 2 1/2 minutes than Jordan.
Cut 5 pieces of string having the following lengths in inches. 2. 99. 55. 74. 27. 6 A subject measures the first length four times by eye. His measurements are 3. 2. 93. 13. 0 Suppose his measurements have a bias of 0. 1 inches. What are the four random errors for his measurements
The four random errors of his measurement are 0.0, 0.1, 0.1, and 0.0.
Random errors are errors in experimental measurements that are caused by unpredictable and unknown changes in the experiment and do not occur in any describable pattern. One example of random errors is Measuring blood pressure.
Bias or systematic errors are due to chance and their source of error is detectable. This type of error can be calculated for an experiment and then it can be added to the measurements that we take.
We know that the Measured value = the Real value of the experiment + Random errors + Systematic errors (Bias). So, to calculate the random error we have to deduct the real value and the systematic error or bias from the measured value of the experiment.
That is,
Random error in 1st observation = 3.0 - 2.9 - 0.1 = 0.0
Random error in 2nd observation = 2.9 - 2.9 - 0.1 = - 0.1
Random error in 3rd observation = 3.1 - 2.9 - 0.1 = 0.1
Random error in 4th observation = 3.0 - 2.9 - 0.1 = 0.0

4. Using Kelly's triangle, what is the slope of
the graph?
You're looking for the slope of the line that forms the triangle's hypotenuse (the diagonal). The slope formula's "rise" and "run" parameters are the two "legs" of the triangle. Slope is a climb or a run.
What is the Slope Triangle?You may determine a line's slope using a slope triangle, which is a visual aid. Slope refers to how steep something is.
Consider ascending 1,000 feet in the air while piloting a plane. You have advanced (horizontally) 3,000 feet when you are 1,000 feet above the ground. You can calculate how steep your rise was using these two measurements.
The inclination is determined by the height at which the plane rises while moving a predetermined distance forward.
To put it another way, it aids in determining the slope of the line linking the plane's starting point and current location.
Triangle with an airplane slope
You may have seen the following slope formula:
Slope: climb / run
The rise is the triangle's vertical distance. Horizontal distance is measured as the run. For our aircraft, we receive:
Slope is equal to 1,000/3,000 feet, or one-third.
In other words, the plane rises one foot vertically for every three feet it moves across the ground.
The ascension of a plane is steeper if it is 2,000 feet above the earth after moving ahead 3,000 feet. It has advanced further vertically for the same horizontal distance. The triangle's slope is less flat in this instance.
Longer is the triangle's horizontal leg.
Slope is defined as: rise/run = 2,000 ft/3,000 ft = 2/3
1/3 is a smaller climb slope for the first airplane than 2/3 is for the second. More steeply ascending is the second aircraft.

The function that represents the arithmetic sequence is an = 18 + (n - 1)(-3). b. The seventh term is 0. c. No, the eight term won't apply as the water trains in 7 hours.
What is arithmetic sequence?The series where the common difference between any two next words stays constant is known as an arithmetic sequence. Let's review what a sequence is. A collection of numbers that follow a pattern is called a sequence.
The given sequence is 18, 15, 12, 9 ...
The common difference between the consecutive terms is:
d = 15 - 18 = -3
d = -3
The sequence is given by the equation:
an = a + (n-1)d
Substituting the value of d= -3 and a = 18 in the equation we have:
an = 18 + (n - 1)(-3)
The function that represents the arithmetic sequence is an = 18 + (n - 1)(-3).
b. The seventh term can be calculated by substituting the value of n = 7.
a(7) = 18 + (7 - 1)(-3).
a(7) = 18 - 18
a(7) = 0
c. No, the eight term won't apply as the water trains in 7 hours.
Hence, The function that represents the arithmetic sequence is an = 18 + (n - 1)(-3). b. The seventh term can be calculated by substituting the value of n = 7is 0. c. No, the eight term won't apply as the water trains in 7 hours.

question content area top part 1 find the volume of the solid generated when the region bounded by and is revolved about the x-axis.
The volume of a solid generated by rotating a region about the x-axis is an important mathematical concept that can be applied in many real-world situations.
The volume of a solid is a measure of the amount of space that the solid takes up in three-dimensional space.
To find the volume of the solid generated when a region is bounded by an equation and revolved around the x-axis, we use a mathematical formula known as the "method of cylindrical shells."
This method involves slicing the solid into thin cylindrical shells, and then finding the volume of each individual shell. The sum of the volumes of the shells will equal the total volume of the solid.
The formula for the volume of a cylindrical shell is given by
=> V = 2πrh,
where r is the radius of the shell, h is the height of the shell, and π is the mathematical constant pi.
To use the method of cylindrical shells, we need to first determine the top and bottom boundaries of the region, and then graph the region.

11) a car travels 5 miles in 20 minutes. how fast was it traveling (in miles/min) (2 pts)
Speed of a car traveling 5 miles in 20 minutes is 0.25 miles/ min.
To calculate the speed of a car, we can divide the total distance it has traveled by the time it took to travel that distance. In this case, the car traveled 5 miles in 20 minutes.
Speed = Distance ÷ Time
Speed = 5 miles ÷ 20 minutes = 0.25 miles/minute
So, the car was traveling at a speed of 0.25 miles per minute, or 15 miles per hour.
It's important to note that this speed only tells us how fast the car was moving at a specific moment in time, and it might have changed throughout its journey. Additionally, this calculation assumes that the car was traveling at a constant speed, which might not always be the case. To get a more accurate representation of the car's speed, we would need to take into account its speed at various points along its route and average those speeds over the entire journey.

what factor(s) enabled spanish conquistadors to seize control of the powerful aztec imperial capital at tenochtitlán in 1521?
The combination of advanced military technology, numerical advantage, and the use of disease as a weapon were critical factors in enabling the Spanish conquistadors to seize control of Tenochtitlán and establish their colonial rule over the Aztec empire.
The Spanish conquest of the Aztec empire in 1521 was a turning point in world history, marking the beginning of Spanish colonial rule in the Americas.
One major factor was the advanced military technology and weaponry of the Spanish. The conquistadors were equipped with steel swords, guns, and armor, while the Aztecs relied on obsidian-tipped weapons and wooden shields.
Another factor was the advantage of numbers. The Spanish arrived in Mexico with a relatively small force of around 500 soldiers, but they were able to recruit indigenous allies and build up their army to around 8,000 soldiers.
