Final answer:
The 8 in the number 8.4 has a value that is 100 times greater than the 8 in the number 0.084. The first 8 represents 8 ones, while the second represents 8 hundredths.
Explanation:
The value of the 8 in 8.4 is 100 times greater than the 8 in 0.084. To understand why, let's remember that each position in a decimal number has a place value that is 10 times less than the place value to its left. For instance, in the number 8.4, the 8 is in the ones place, meaning its value is 8 ones or '8'. However, in the number 0.084, the 8 is in the hundredths place, so its value is 8 hundredths or '0.08'.
Therefore, when comparing the two eights, we see that:
The 8 in 8.4 equals 8 ones (8 × 1 = 8).
The 8 in 0.084 equals 8 hundredths (8 × 0.01 = 0.08).
To find a number whose 8 is worth 100 times less than the 8 in 8.4, we need the 8 to be two places to the right of the decimal point, which is the hundredths place. The number 0.084 satisfies this because 8 ones (the value of the 8 in 8.4) are 100 times greater than 8 hundredths (the value of the 8 in 0.084).

Find the expressions that are equal..use the equal expressions to write true number sentences ??
Final answer:
To find equal expressions, identify different expressions that have the same value when evaluated. Write true number sentences using these equal expressions.
Explanation:
In order to find equal expressions, we need to identify different expressions that have the same value when evaluated. For example, the expressions 3 + 4 and 7 are equal because both evaluate to 7. We can use these equal expressions to write true number sentences, such as 3 + 4 = 7.
Another example is the expressions 2 * 5 and 10, which are equal because both evaluate to 10. We can write the true number sentence 2 * 5 = 10 using these equal expressions.
It's important to note that we're looking for expressions that are equal in value, not necessarily in form. For example, the expressions x + 2 and 3 + x are equal because they represent the same value for any given value of x. We can write the true number sentence x + 2 = 3 + x using these equal expressions.

Over the course of a year,a tractor-trailer commutes 160,000 miles across America.Assuming a trucker changes his tires every 40,000 miles,and that he starts with a brand new set of tires,how many sets of tires will he use in a year?
Given that a trucker changes his tires every 40,000 miles, if he drives 160,000 miles in a year, he will use a total of 5 sets of tires.
Explanation:The question is asking us to find out how many sets of tires a trucker will use when he drives 160,000 miles in a year, given that he changes his tires every 40,000 miles. To find out, we need to do some simple division.
First, we need to take the total distance traveled, which is 160,000 miles, and divide it by the distance the trucker can travel on a set of tires, which is 40,000 miles. 160,000 miles divided by 40,000 miles equals 4.
So, if the trucker starts the year with a fresh set of tires, he will need to change his tires 4 times throughout the year, meaning he will use a total of 5 sets of tires.

G find the point on the plane x + 4y + 2z =14 closest to the point (1,1,1)
Answer:
(4/3, 7/3, 5/3)
Step-by-step explanation:
The line perpendicular to the plane through the point will be ...
... (x, y, z) = (1, 1, 1) +t(1, 4, 2)
Using this expression for (x, y, z), we can find the point on the line where it intersects the plane. That point is the one of interest.
... (1 +t) +4(1 +4t) +2(1 +2t) = 14 . . . . . substituting for (x, y, z) in the equation of the plane
... 7 +21t = 14 . . . . . collect terms
... 21t = 7 . . . . . . . . subtract 7
... t = 7/21 = 1/3 . . . divide by 21
The point of interest is ...
... (x, y, z) = (1, 1, 1) + (1/3)(1, 4, 2) = (1 1/3, 2 1/3, 1 2/3)
The senior class has 412 students. They are assigned to different homerooms. There are 28 students in the smallest homeroom and the remaining 12 homerooms have the same number of students. How many students are in each of the remaining 12 homerooms?
There are 32 students in each of the remaining 12 homerooms.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Total students in a senior class = 412 students.
Total number of students in the smallest homeroom = 28
And, 12 homerooms have the same number of students.
Let number of students in each of 12 homerooms = x
So, Total number of students in each of 12 homerooms = 12x
Then, We can formulate;
12x + 28 = 412
Solve for x as;
12x + 28 = 412
Subtract 28 as;
12x + 28 - 28 = 412 - 28
12x = 384
Divide by 12;
x = 32
Thus, There are 32 students in each of the remaining 12 homerooms.

Step-by-step explanation:
A car rents for $250 per week plus $0.50 per mile.find the rental cost for a two-week trip of 500 miles for a group of three people
The total cost of a two-week car rental for a trip of 500 miles, split three ways, is $250 per person.
Explanation:In this calculation, we'll break down the costs into two parts: the weekly rental cost and the mileage cost. The car rents for $250 per week which, for two weeks, is $250 x 2 = $500. The cost for mileage is $0.50 per mile, hence for 500 miles, it will be $0.50 x 500 = $250. Adding these two gives us the total cost, $500 + $250 = $750 for the trip.
It's also mentioned that there are three people sharing this cost. So, the cost per person would be $750 divided by 3 which gives us $250 per person for the two-week trip of 500 miles.

A machine is made up of 3 components: an upper part, a middle part, and a lower part. the machine is then assembled. 5 percent of the upper parts are defective, 4 percent of the middle parts are defective, and 1 percent of the lower parts are defective. what is the probability that a machine is not defective
Final answer:
The probability that a machine with three components (upper, middle, and lower parts) is not defective is found by multiplying the non-defective probabilities of each part. Calculating this gives a probability of 90.24% that the machine is non-defective.
Explanation:
The question asks what is the probability that a machine with three components (upper, middle, and lower parts) is not defective. To calculate this, we first note the probability of each part being non-defective:
Upper part non-defective probability = 95% (since 5% are defective, 100%-5% = 95%)
Middle part non-defective probability = 96% (since 4% are defective, 100%-4% = 96%)
Lower part non-defective probability = 99% (since 1% are defective, 100%-1% = 99%)
Since the machine is not defective only if all three parts are non-defective, we multiply these probabilities together:
Probability(machine is non-defective) = Probability(upper is non-defective) * Probability(middle is non-defective) * Probability(lower is non-defective)
Probability(machine is non-defective) = 0.95 * 0.96 * 0.99 = 0.9024 or 90.24%
You buy 3.17 pounds of apples, 1.25 pounds of pears, and 2.56 pounds of oranges. What is your total bill rounded to the nearest cent?
Answer:
Total bill = 7 pounds .
Step-by-step explanation:
Given : You buy 3.17 pounds of apples, 1.25 pounds of pears, and 2.56 pounds of oranges.
To find : What is your total bill rounded to the nearest cent.
Solution : We have given
Apple = 3.17 pounds
Peas = 1.25 pounds
Orange = 2.56 pounds.
Total bill = 3.17 + 1.25 +2.56 = 6.98

Total bill = 7 pounds .
Therefore, Total bill = 7 pounds .
Without knowing the price per pound of the fruit, it's impossible to calculate the total bill. However, if you knew the individual prices, like in the example, you could add up these amounts together to find the total cost.
Explanation:The question you're asking appears to be missing some important information. Specifically, we would need to know the price per pound of the apples, pears, and oranges in order to calculate your total bill. However, let's use an analogous example. Suppose you buy 10 apples at 50 cents each, 12 bananas at 20 cents each, and 2 bunches of grapes at 65 cents each. Your total cost would be $5.00 for apples, $2.40 for bananas, and $1.30 for grape.
