The absolute value is useful in solving problems involving distance, temperature, and error in measurement. The word problem is described below.
A word problem involving absolute value is as following:
John lives 3 blocks away from his school.
One day, he walked to school and noticed that he accidentally left his backpack at home.
He decided to go back home to get it. When John got back home, he realized that he forgot his backpack was actually in his car.
John's car is parked 5 blocks away from his house. How far did John walk in total?
To solve this problem, we need to use absolute value.
John walked 3 blocks to school, then back home, and then 5 blocks to his car.
The total distance he walked would be the absolute value of the difference between the distance from school to home and the distance from home to car:
|3 - 5| = 2
Therefore, John walked a total of 2 blocks that day.

1_9644=100000 rounded to the nearest hundred thousand
When rounding 1,964,400 to the nearest hundred thousand, the answer is 1,900,000.
Explanation:When rounding 1,964,400 to the nearest hundred thousand, we look at the digit in the hundred thousands place. If it is 5 or greater, we round up. If it is less than 5, we round down. In this case, the digit is 4, so we round down. Therefore, 1,964,400 rounded to the nearest hundred thousand is 1,900,000.

x-2.8=9.5 What does x equal ?
Evaluate the function rule for the given value. f(x) = 3x for x = –5
Final answer:
To evaluate the function f(x) = 3x for x = –5, substitute in the value to get f(–5) = –15. For the second part, none of the options perfectly match the description, but y = x² is closer as it is a quadratic function.
Explanation:
To evaluate the given function rule f(x) = 3x for x = –5, you simply substitute –5 in for x in the function. Here is the calculation:
f(–5) = 3 * (–5) = –15
Now, regarding the second part of the question, at x = 3, the function f(x) has a positive value with a positive slope that is decreasing in magnitude with increasing x. The function y = x² fits this description because it is a quadratic function where the slope (the derivative) is 2x. At x = 3, the slope is positive (2 * 3 = 6), and as x increases, the slope increases, but the rate of increase in slope (the second derivative) is constant, not decreasing. Hence, neither option a nor b perfectly fits the condition of a positive slope that is decreasing in magnitude with increasing x. However, option b, y = x², is closer to the description compared to the linear option a, y = 13x, which has a constant slope.
You measure the width of a doorway and find that it is 0.93 m wide. Find the greatest possible error of your measurement
Answer:
0.5 m
Step-by-step explanation:
The greatest possible error is 1/2 of the unit you are measuring in.
We are measuring in meters; this means the greatest possible error is 0.5 m.
Answer:
The right answer is 0.005m
Step-by-step explanation:
The greatest possible error in a measurement is the half of the measuring unit, it is one hald of the precision unit.
To solve it first you should recognize the measurement unit, in this case meters.
Then, because it is 0.93, you should notice that the last decimal occupies the place of the hundredth, so the GPE might be: 0.01/2 equal to 0.005, your answer.

Hope this helps
With the same rate, Aubrey can run 9 miles in 90 minutes and this can be determined by using the unitary method.
Given :
Aubrey can run at a pace of six miles per hour.
The following steps can be used in order to determine the total miles can Aubrey run in ninety minutes at the same rate:
Step 1 - The unitary method can be used in order to determine the total miles can Aubrey run in ninety minutes at the same rate.
Step 2 - Remember in 1 hour there are 60 minutes.
Step 3 - Remember according to the given data, Aubrey can run at a pace of six miles per hour. That means Aubrey can run six miles in 60 minutes.
Step 4 - If Aubrey can run 6 miles in 60 minutes then in 90 minutes she can run:

a spool of ribbon has 18 feet on it. pieces measuring of 8 inches will be cut from the spool of ribbon. how many 8 inch segments will be cut from the spool of ribbon
show work
By dividing the total length by the length of the pieces, we conclude that we can make 2 of these pieces.
How many 8 inch segments will be cut?To get this, we need to divide the total length by the length of the desired pieces, and then round to the next (lowest) whole number.
Then we get:
N = 18ft/8ft = 2.25
Rounding to the next whole number we get 2, so we conclude that with 18t of ribbon we can make 2 pieces of 8ft each.

A machine cuts a strip of carpet into two pieces. The length of the smaller piece is 5 meters greater than the length of the larger piece. If the length of the smaller piece is 12 meters, the length of the bigger piece is meters and the total length of the carpet is meters.
Answer:
The length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.
Step-by-step explanation:
The length of the smaller piece is 5 meters greater than the length of the larger piece.
i.e. Length of larger piece=Length of smaller piece+5
The length of the smaller piece is 12 meters.
So, Length of larger piece=12+5
=17 meters
Total Length of carpet=Length of smaller piece + Length of larger piece
= 12+17
= 29 meters
Hence, the length of the bigger piece is 17 meters
and the total length of the carpet is 29 meters.

identify an equation in point-slope form for the line parallel to y=1/2x-7 that passes through (-3,-2)
To find an equation in point-slope form for a line parallel to y=1/2x-7 that passes through (-3,-2), we can use the fact that parallel lines have the same slope. The equation of the parallel line is y = (1/2)x + 5/2.
Explanation:To find an equation in point-slope form for a line parallel to y = (1/2)x - 7 that passes through the point (-3, -2), we need to use the fact that parallel lines have the same slope.
The given line has a slope of 1/2, so the parallel line will also have a slope of 1/2.
Using the point-slope form y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope, we substitute the values to get the equation y - (-2) = (1/2)(x - (-3)). Simplifying this equation gives us the final answer: y = (1/2)x + 5/2.

A small train at an amusement park is carrying passengers. Half of the passengers are 6 years old, 1 over 10 are 7 years old, 1 fifth are 8 years old, and 1 fifth are 9 years old.
What is the expected age for one of the passengers on the train?
6 years
7.1 years
8 years
8.5 years
The expected age for one of the passengers on the train is 7.1 years. This can be explained by following steps:
Following are the calculation for the expected age given
½ = 6 years old
1/10 = 7 years old
1/5 = 8 years old
1/5 = 9 years old
With the help of the above information, expected age can be calculated as follows:
Expected age = ½*6+1/10*7+1/5*8+1/5*9
= 6/2+7/10+8/5+9/5
=3+0.7+1.6+1.8
= 7.1
