The Utica Boilermaker is a 15-kilometer road race. Sara is signed up to run this race and has done the following training runs:

I. 10 yards
II. 44,880 feet
III. 15,560 yards

Which run(s) are at least 15 kilometers?

Option A: I, only
Option B: II, only
Option C: I and III
Option D: II and III

Answers

the answer to this problem is B, I just converted the value to km

The values of following are 10 yards = 0.009144 km, 44,880 feet = 13.678, 15,560 yards = 14.228

What is kilometer ?

"The kilometer spelt kilometer in American English, is a unit of length in the metric system, equal to one thousand meters (kilo- being the SI prefix for 1000). It is now the measurement unit used for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the United Kingdom where the statute mile is the unit used."

Given,

(i) 10 yards

1 yard = 0.0009144

then 10 yard = 10*0.0009144 = 0.009144 km

(ii) 44,880 feet

1 feet  = 0.00030478

then 44,880 feet = 44,880*0.00030478 = 13.678 km

(iii) 15,560 yards

15,560 yards =  15,560 *0.0009144 = 14.228 km  

Hence, D is the correct option.

A chart labeled table B: effect of mass on temperature with initial temperature as 25 degrees Celsius, mass w is 1.0 kilograms and h is 500 m. The chart is 5 columns and 5 rows. The first column is labeled mass c in kilograms with entries 1.0, 3.0, 6.0, 9.0. The second column is labeled temperature final in degrees celcius with entries 26.17, 28.52, 32.03, 35.55. The third column is labeled change in temperature in degrees celcius with entries 1.17, 3.52, 7.03, 10.55. The fourth column is labeled gravitational potential energy in kilojoules with no entries. The last column is labeled delta H in kilojoules with no entries. Use the data provided to calculate the gravitational potential energy of each cylinder mass. Round your answers to the nearest tenth. 3 kg: kJ 6 kg: kJ 9 kg: kJ

Answers

Answer:

3 kg= 14.7

6 kg= 29.4

9 kg= 44.1

Step-by-step explanation:

The gravitational potential energy of the cylinders as follows:

3 kg: 14.7 kJ, 6 kg: 29.4 kJ, and 9 kg: 44.1 kJ

What is the GPE?

GPE is gravitational potential energy, mass is the mass of the object in kilograms, gravity is the acceleration due to gravity in meters per second squared (usually taken to be 9.8 m/s²), and height is the height of the object above the reference point in meters.

To calculate the gravitational potential energy (GPE) of an object, you need to know its mass, the acceleration due to gravity, and its height above a reference point. You can use the formula:

GPE = mass × gravity × height

In this case, the mass of each cylinder is given in the first column of the chart, and the height of the cylinders is 500 meters. However, the acceleration due to gravity is not given in the chart. We can assume that it is 9.8 m/s², but if you have a different value, you should use that instead.

Using these values, we can calculate the gravitational potential energy of the 3-kilogram cylinder as follows:

GPE = 3 kg × 9.8 m/s² × 500 m = 14700 kg m/s²

Converting this to kilojoules gives us:

GPE = 14700 kgm/s² × (1 J/1 kgm/s²) = 14700 J

Converting this to kilojoules (kJ) gives us:

GPE = 14700 J / 1000 J/kJ = 14.7 kJ

Therefore, the gravitational potential energy of the 3-kilogram cylinder is 14.7 kJ.

You can use the same process to calculate the gravitational potential energy of the 6-kilogram is 29.4 kJ and the 9-kilogram cylinders is 44.1 kJ.

A train is traveling at a constant speed and goes a distance of 7 1/2 kilometers in 6 minutes the train will continue at this speed the train will travel a distance of d kilometers in m minutes write an equation that represents the relationship between d and m

Answers

Answer:

392939939393939399393939393

Step-by-step explanation:

An equation that represents the relationship between d and m can be written as d = 1.25 m.

What is Speed?

Speed of an object is the rate of change of position of an object in any direction.

Speed is a scalar quantity because it does not have any direction, it only has magnitude. Speed with direction is called velocity.

The formula for calculating speed is,

Speed = Distance / Time

Given distance the train travelled = 7 [tex]\frac{1}{2}[/tex] kilometers

                                                        = 15/2 kilometers

                                                        = 7.5 kilometers

Time taken to travel the distance = 6 minutes

Speed = 7.5 / 6

           = 1.25 kilometers / minute

Given that speed of the train is constant.

Hence for any distance 'd' kilometers in 'm' minutes,

d / m = 1.25

d = 1.25m

Hence d and m can be related by the equation d = 1.25m.

Baylor is #3 with a win to loss ratio of 11-2 for this season while Taylor is #1 with their unbeaten 11-0. Texas hit 294 as a team while Baylor hit 233, Texas Longhorns so far is the best hitting team efficiency wise in the country with a score of .359. Baylor took the lead in the first two sets when they made their first o2 comeback ever since Nov 1st of 2017. Hannah Sedwick, #14 Setter, in Baylor to me, seems like a really focused player, they mentioned how she was out for most of the season due to a fracture in her leg but yet she seems so active and awake, all of the players put in an effort but Hannah actually commits. When blocking the ball, her entire body became stiff and she carried the win for her team. On the other team there's Yossiana Pressley, #32 Outside Hitter, on the Baylor Bears who had 29 kills in the first part, and I have to say she completely dominated Baylor's with her spikes. Nilani Iosia, #12 Libero, in the Texas Longhorn scored 15 digs and an excellent passing percentage while Lauren Harrison, #31 Outside Hitter, Baylor Bears was the second leading attacker in the first part. Another notable player is Jhenna Gabriel, #2 setter, in Texas Longhorns who is the reigning national player of the big 12 player of the year.The Texas Longhorns came through this game with a ratio of 3-2 remaining unbeaten for the 12th time in a row. In one play I remember Butler barely hit the ball over the net and scored. It wasn't such a critical play but it had strategy and reasoning behind it. While Baylor prepared for the worst by upgrading the offense, they left their defense bare. That's why I think it was smart how Butler quickly noticed that and surprised them. This team had a quick dynamic where they would hit the ball before the blockers could completely cover over the net. Somewhere in the beginning, I immediately had a feeling Taylors had something the Bears didnt which helped them stay unbeaten. Id say its how they made sure to make their hits clear so that it can go through the blockers, and they were very efficient with passing the ball to their hitters. They shouldve had a clearer touch with the ball as well even if they won, it looked like both teams couldnt block the ball most of the time.The losing team, Baylor Bears, was honestly close to Texas's score. I couldn't stop focusing on Yossiana Pressley in Baylor, she had perfect momentum and sharp reflexes. Not just because of her kills but I'd say she was the MVP player of this game. The team was always so supportive as well especially whenever a small mistake occurred like a foul for going over the line on a serve. I have to admit, most of their sets were average, and not to mention how their hitters would constantly hit out of the court. It seemed as if they were trying to get it to hit the net so Taylor's would have more difficulty blocking it, if that's the case then it's a very smart move, but otherwise, if they just happened to be lucky then I'd consider it a miracle. This team could always track the ball but when it came to controlling the ball, they were late and had bad momentum. The sad part is, the Baylor Bears are such a good team, I personally liked them more in the beginning where I saw more action, but whenever it came down to the ball constantly being passed back and forth it seemed as if they lost energy which to me, ultimately led to the downfall of their team.

Both have their advantages and disadvantages. Farmers' markets have fresh and local produce, and often you get a chance to meet the people who grow your food. This isn't the case with grocery stores, where you'll never get to meet the farmers. Grocery stores are starting to have more local products, though, and they have a better variety of goods. Another thing to consider is the setting itself. Farmers' markets are usually in more pleasant, open-air locations where there's often live music playing. Grocery stores, on the other hand, can be busy and uncomfortable if you don't like shopping. The pleasant atmosphere comes at a price, though, as your bill at a farmers' market is likely to be 25 percent more than at a grocery store.
