A train is traveling from New Orleans to Memphis at a constant speed of 79 mph. New Orleans and Tennessee are 395.1 miles apart. How long will the train will the train take to reach Tennessee? Round to the nearest tenth.
Using the formula 'Time = Distance / Speed', the train traveling from New Orleans to Memphis at a constant speed of 79 mph would take approximately 5.0 hours to cover the distance of 395.1 miles.
Explanation:The subject of this task is about calculating travel time given a certain speed and distance. In this case, we have a train traveling from New Orleans to Memphis at a constant speed of 79 mph, and we're asked to find out how long it would take for the train to cover the distance of 395.1 miles between the two cities.
The principle used to find this is a basic mathematical concept involving time, speed, and distance, represented in this formula: Time = Distance/Speed. For this question, the distance is 395.1 miles and the speed is 79 mph.
Applying this information into the formula, the calculation becomes: Time = 395.1 miles / 79 mph = 5 hours. Rounded to the nearest tenth, the time it takes for the train to get to from New Orleans to Memphis at a constant speed of 79 mph is approximately 5.0 hours.

A group of 4people share 1/2 pound of almonds how many pounds of almonds does each person get
Answer:
each person gets 1/8 pounds of almonds
Step-by-step explanation:
Four persons will divide ½ pound of almonds in four pieces, one piece for everyone, so translating this to an equation is:
X = [tex]\frac{1}{2}[/tex] ÷ 4
Where X represent how much of almonds will have everyone.
For divide fractional numbers we do a multiplication in cross, that means that the higher number in the first fraction will be multiplicated with the lowest number of the second fraction ( if the second number is not a fraction, we will assume that have a the number 1 is the lowest part) and the lowest number of the first fraction will be multiplicated with the highest number of the second number.
Then, we can rewrite the initial equation and solve as:
X= [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{4}{1}[/tex]
[tex]X=\frac{1*1}{2*4} = \frac{1}{8}[/tex]
So, each person is going to get 1/8 pounds of almonds.
A hand-held digital music player was marked down by 1/4 of the original price.
a. If the sales price is $128.00, what is the original price?
b. If the item was marked up by 1/2 before it was placed on the sales floor, what was that the store paid for the digital player.?
Answer:
a) The original price of music player is $170.66
b)If the item was marked up by 1/2 before it was placed on the sales floor, the store paid $213.325 for the digital player.
Step-by-step explanation:
Let the original price be x
A hand-held digital music player was marked down by 1/4 of the original price.
So, Discount = [tex]\frac{1}{4}x[/tex]
So, Sale price =[tex]x-\frac{x}{4}=\frac{3x}{4}[/tex]
We are given that the sales price is $128.00
So, [tex]\frac{3x}{4}=128[/tex]
[tex]x=\frac{128 \times 4}{3}[/tex]
[tex]x=170.66[/tex]
a) The original price of music player is $170.66
The item was marked up by 1/2 before it was placed on the sales floor.
So, Cost = [tex]170.66+\frac{1}{4} \times 170.66[/tex]
Cost = [tex]213.325[/tex]
b)If the item was marked up by 1/2 before it was placed on the sales floor, the store paid $213.325 for the digital player.

The table shows the cost (in cents) of producing and distributing each coin for two years.
Quarter- 4.38 in 2000, 9.78 in 2007
Dime- 1.92 in 2000, 4.09 in 2007
Nickel- 3.16 in 2000, 9.53 in 2007
Penny- 0.82 in 2000, 1.67 in 2007
Part A) Which coins costs less to make than they are worth? Which coins cost more than they are worth?
Part B) How much more does it cost to produce 50 of each coin in 2007 than in 2000?
Plz help!!! Due tomorrow!!
In 2000 and 2007, quarters and dimes cost less to produce than they are worth while nickels and pennies cost more in 2007. The increased cost to produce 50 of each coin in 2007 vs 2000 can be calculated by multiplying the increase in production cost for each coin by 50 and summing up the totals.
Explanation:In Part A, you're asked to compare the face value of each coin to its production cost. For a quarter, the face value is 25 cents which is higher than the production cost of 4.38 cents in 2000 and 9.78 cents in 2007. This is true for the dime as well, face value of 10 cents compared to production costs of 1.92 cents in 2000 and 4.09 cents in 2007. Hence, quarters and dimes cost less to make than they are worth. Nickel and Penny cost more than they are worth in 2007 since their production cost exceeds their face value (5 cents for Nickel and 1 cent for Penny).
For Part B, you need to calculate the difference in the production cost for each coin between 2007 and 2000, and then multiply that by 50. For example, the cost for a quarter increased by 5.4 cents from 2000 to 2007 (9.78-4.38). Multiplied by 50, that's an increase of 270 cents (or $2.70). Do the same for each coin and sum up all the increases to get the total increased cost for 50 of each coin.

Which if these are least likely to describe a distance below sea level?
A. Whole number
B. Integer
C. Rational number
D. Real number
Thanks!
The whole numbers are least likely to describe a distance below sea level.
What is a whole number?All the counting numbers starting from zero are called whole number. It is the number which is not represented in the form of a fraction.
Given that, what is least likely to describe below sea level,
Below sea level is a distance which is calculated in negative because it is a distance below the sea level.
A rational number can be negative or positive, hence, it can or can not describe the distance below sea level.
Integers are the collection of negative and positive numbers, so it can also describe above or below both the distance from sea level.
Real numbers are the numbers which are not imaginary and can be found on number scale, so it can be both negative or positive and hence can describe above or below both the distance from sea level.
Whole numbers are numbers starting from zero, and hence not includes negative numbers, therefore, a whole number can not describe the distance from below sea level.
Hence, the correct answer is whole number.

triangles ABC and DEF are similar. what is the length of side EF
Answer:
The length of the side EF is 3cm.
Step-by-step explanation:
As both triangles are similar, their corresponding sides are in proportion.
This means that:
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
[tex]\frac{3}{4.5}=\frac{2}{x}=\frac{5}{7.5}[/tex]
This proportion is called the scale factor.
Knowing this, we can find the value of x
[tex]\frac{3}{4.5}=\frac{2}{x}[/tex]
[tex]x=2 *(\frac{4.5}{3})=\frac{9}{3}=3cm[/tex]
So, the lenght of side EF is 3cm.

Which statements about opposites are true?
Select each correct answer.
The opposite of a number is always a negative number.
The opposite of the opposite of a number is the number itself.
A non-zero number and its opposite are located on opposite sides of zero on a number line.
The opposite of a number is 1 divided by that number.
The opposite of a number is the same distance from zero on the number line but on the other side. Therefore, the opposite of a number is not always negative, the opposite of the opposite of a number is the number itself, and non-zero numbers and their opposites are on opposite sides of zero. The reciprocal of a number (1 divided by that number) is not its opposite.
Explanation:In the realm of mathematics, the term 'opposite' refers to the number that is the same distance from 0 on the number line, but on the other side. With this definition, we can state that:
The opposite of a number is not always a negative number. For example, the opposite of -7 is 7, which is positive.The opposite of the opposite of a number is indeed the number itself. For instance, the opposite of -3 is 3, and the opposite of 3 is -3.A non-zero number and its opposite are indeed located on opposite sides of zero on a number line.The opposite of a number is not 1 divided by that number - this is actually the reciprocal of a number, not its opposite.Learn more about Opposites in Mathematics here:https://brainly.com/question/36830748
