Rebecca is planning to visit relatives in Omaha Nebraska. She will drive 610 miles from her home in Indianapolis. On her trip back home, will she be traveling –610 miles? Use mathematical vocabulary to justify your answer.
Rebecca will travel another 610 miles on her way back from Omaha to Indianapolis, not -610 miles, as distance is a scalar quantity and does not adopt a negative sign. The total round trip distance is therefore 1220 miles.
Explanation:When Rebecca returns home from her trip to Omaha, Nebraska, she will indeed travel another 610 miles. However, the use of -610 miles might be misleading in this context. In mathematics, especially when discussing distance, the concept of negative numbers often represents direction rather than decrement. Therefore, saying Rebecca will travel -610 miles could imply direction, but since she is returning to her starting point, the actual distance traveled is 610 miles, the same as her outbound trip.
Distance, as a quantity, is scalar and therefore always non-negative. When keeping track of total distance travelled, irrespective of direction, the concept of positive and negative doesn’t apply—the distance simply adds up. So, the total distance Rebecca travels (going to Omaha and then back to Indianapolis) would be 1220 miles. This demonstrates the concept of absolute value in mathematics, where the focus is on the magnitude of a number without regard to its sign.

What does it mean to say that a number is a perfect square? Give on example of number that is a perfect square and of one that is not. Explain your examples.
Answer:
A number called a perfect square means that the number has an exact squared root. In other words, the number has an squared power, which is exact.
Other way to see this, it's taking natural number 1, 2, 3, 4... then, applying the squared power to each one, the results of each squared power is what we call a perfect square. For example, 1, 4, 9, 16, 25, 36,..., are all perfect square, because they are the result of a squared power:
[tex]1^{2}=1\\2^{2}=4\\3^{2}=9\\4^{2}=16\\5^{2}=25\\6^{2}=36[/tex]
a story problem for 7 ×6=42
find x on the triangle
Mr. Winkle downloaded 34 more songs than Mrs. Winkle downloaded.
Together they downloaded 220 songs. How many songs did each download?
Please show how you got it...
Mrs. Winkle downloaded 93 songs and Mr. Winkle downloaded 127 songs, which equals the total of 220 songs they downloaded together.
The total number of songs downloaded by Mr. and Mrs. Winkle is 220. If Mr. Winkle downloaded 34 more songs than Mrs. Winkle, we can set up a system of equations to solve for the number of songs each downloaded. Let x represent the number of songs Mrs. Winkle downloaded, so Mr. Winkle downloaded x + 34 songs.
The equation representing the total number of songs downloaded by both is:
x + (x + 34) = 220
Combining like terms gives us:
2x + 34 = 220
Subtracting 34 from both sides, we get:
2x = 186
Dividing both sides by 2, we find:
x = 93
So, Mrs. Winkle downloaded 93 songs and Mr. Winkle downloaded 93 + 34, which is:
Mr. Winkle downloaded 127 songs.

Name the place value to which each number was rounded.0.546 to 0.55
The value of each digit in a number is known as the place value. The place value to which each number was rounded.0.546 to 0.55 is hundredths place value.
What is the place value of a digit in a number?The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.
Identification of the place value of a digit in a number:
The place values on the left of the decimal point start as ones, tens, hundreds, and so on.The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths and so onThe tens mean multiply by 10The tenth means the tenth part of that digit which is that digit divided by 10Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits
Round 0.546 to the nearest hundredths place value.
We have, 0.546
Rounding to the nearest hundredths place value
4 is in hundredths place value
Since 6 is greater than 5 we can write 4 as 5.
0.55 is our answer.
Thus, if we round to the nearest hundredths place value we get 0.55.

7x + 8 = 36
The correct simplification of [tex]7x + 8 =36[/tex] for value of x is 4.
Given expression is:
[tex]7x+8 = 36[/tex]
To simplify the expression,
isolate [tex]x[/tex] on one side of the expression or rearrange the expression rearranging like and unlike terms.
Subtract 8 from both side of the expression:
[tex]7x + 8 -8 = 36 -8[/tex]
[tex]7x = 36-8[/tex]
[tex]7x = 28[/tex]
To solve for [tex]x[/tex] , Divide both side of the equation by 7.
[tex]\dfrac{7x}{x} = \dfrac{28}{7}[/tex]

Step-by-step explanation:
A train leaves a station at 10:40 a.m. and arrives at its destination at 1:20 p.m. Find the distance between the stations if the average speed of the train was 60 mph.
Answer:
160 miles.
Step-by-step explanation:
A train leaves a station at 10 : 40 a.m.
and arrives at its destination at 1 : 20 p.m. = 13 : 20 p.m.
Now we will subtract the time of departure to calculate the total time taken by the train.
13 : 20
- 10 : 40
2 : 40 Train took 2 hours 40 minutes to reach its destination.
Now we will convert 2 hours 40 minutes to decimal form.
2 hours and (40/60) = 2.66 minutes
If the average speed of the train was 60 miles per hour.
Since in one hour train traveled 60 miles
Therefore, in 2.66 hours train traveled = 60 × 2.66
= 159.6 ≈ 160 miles
The distance would be 160 miles.
