Answer:
[tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.
Step-by-step explanation:
We are given that in 1995, the USPS approximated that they handled [tex]1.8 \times 10^{11}[/tex] pieces of mail and in 2010, the USPS reported that they handled [tex]1.7 \times 10^{11}[/tex] pieces.
To find how many more pieces of mail were handled in 1995 than in 2010, we do subtraction of the pieces of mail that were handled in both the years.
Pieces of mail handled in 1995 = [tex]1.8 \times 10^{11}[/tex]
Pieces of mail handled in 2010 = [tex]1.7 \times 10^{11}[/tex]
As it is clear that more pieces of mail were handled in 1995.
So, Pieces of mail handled in 1995 - Pieces of mail handled in 2010 = [tex](1.8 \times 10^{11}) -(1.7 \times 10^{11})[/tex]
= [tex]10^{11} \times (1.8 -1.7)[/tex]
= [tex]10^{11} \times 0.1[/tex] = [tex]1 \times 10^{10}[/tex]
Hence, [tex]1 \times 10^{10}[/tex] more pieces of mail were handled in 1995 than in 2010.

NEED MATH HELP NOW. PLEASE HELP.
Answer:
The x-intercepts are (-2, 0) and (4, 0). I know this because it's written in intercept notation. To find the y-intercept we'll expand.
-(x + 2)(x - 4) = -x² + 2x + 8 so the y-int. is (0, 8). To find the rest we'll complete the square.
-x² + 2x + 8 = -(x² - 2x) + 8 = -(x -1)² + 1 + 8 = -(x - 1)² + 9 so the vertex is (1, 9) and the axis of symmetry is x = 1. This means that the domain is all real numbers and the range is y ≤ 9.

D-3
E-2
Step-by-step explanation:
They all have the same explanation u have to find the point where the line coincides with the x and y axis
E.g on how to work out
Note when the value of y is zero u get the x coordinate and when x is zero u get the y coordinate
C=2x+y=4
To get x 2x+0=4 x=2
Y 0+y=4 y=4
After doing so u locate the line that passes through (2,0),(0,4)

Answer:
88 cm²
Step-by-step explanation:
6*2*2+2*2= 28 cm² sides
6*3*2= 36 cm² top and bottom
3*4*2= 24 cm² front and back
28+36+24= 88 cm²
Answer:
[tex]6 \times 2 + 2 \times 2 = 28 \\ \\ 6 \times 3 \times 2 = 36 \\ \\ 3 \times 4 \times 2 = 24 \\ \\ 28 + 36 + 24 = 88cm {}^{2} [/tex]
David worked 7 1/3 hours today and planted 11 trees. It takes him about the same amount of time to plant each tree. How long did it take him to plant each tree?
Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
It takes David 2/3 hours to plant each tree.
Since it takes David 7 1/3 hours today to plant 11 trees.
Therefore time taken to plant 11 trees = 7 1/3 hours = 22/3 hours
The time taken to plant each tree = 22/3 hours ÷ 11 trees = 2/3 hours per tree
Therefore it takes David 2/3 hours to plant each tree.

Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2
If f(x) is a linear function and given f(3)=−3 and f(8)=1, determine the linear function. a.) What is the slope? (Be sure to leave your answer in reduced fraction form.) b.) What is the y-intercept? (Be sure to leave your answer in reduced fraction form.) c.) What is f(x)? f(x)=
Answer:
slope is 4/5
y intercept is -27/5
f(x) = 4/5x -27/5
Step-by-step explanation:
The slope is
f(8) - f(3)
----------------
8-3
1 - -3
------------
8-3
1+3
------------
5
4/5
We can use the slope intercept form to find the y intercept
y = mx+b where m is the slope and b is the y intercept
y = 4/5x +b
Using the point (8,1)
1 = 4/5(8)+b
1 = 32/5 +b
Subtract 32/5 from each side
5/5-32/5 = b
-27/5 = b
y = 4/5x -27/5
f(x) = 4/5x -27/5

To locate the percentile for a given observation in a data set, the data must be ___________. Select one: a. Displayed in a histogram b. Sorted and listed from the minimum to the maximum values c. Distributed symmetrically around the mean d. Summarized in a frequency distribution
Answer:
b. Sorted and listed from the minimum to the maximum values
Step-by-step explanation:
A percentile can be defined a measure that is made use of statistics.
A percentile is a statistical measure that indicates or shows comparison amongst a given set of data.
A percentile tells us the value or scores below which a percentage of a given observation in a data set falls.
In other to be able to effectively obtain the percentile if a given set of data, the following steps must be taken.
Step 1: Arrange, sort and list the values of the given the data set in order from lowest to the highest
Step 2: Multiply the percentage (also represented by P ) by total number of values in the data set( also represented by N)
Step 3: The value obtained from step 3 is know as the rank and this would helps us to find the percentile f a given data set.
The formula for calculating a percentiles is given as
= (P/100) x N,
where
P = percentile
N = number of values in a data set (sorted or arranged from lowest to highest)
n = Rank of a given value.

Which answer choice shows the correct calculation by using the Pythagorean Theorem for the distance of
between Elibri's apartment and Elibri's school, namely HE?
Answer:
|AC| = 4.47 units (question attached as image)
Step-by-step explanation:
The question lacks sufficient details. We wil however consider a similar example (image attached) to understand how to solve questions using Pythagoras theorem.
We will calculate for |AC| using Pythagoras theorem, we have:
|AC|² = |AB|² + |BC|²
|AC| = ?, |AB| = 4 units, |BC| = 2 units
|AC|² = 4² + 2² = 16 + 4
|AC|² = 20 ⇒ |AC| = [tex]\sqrt{20}[/tex]
|AC| = 4.472135955 ≈ 4.47
|AC| = 4.47 units
What is the product? One-eighth times three-elevenths 3 over 88 1 over 22 4 over 19 35 over 88
Answer:
[tex]\frac{3}{88}[/tex]
Step-by-step explanation:
Given
One-eighth times three-elevenths
Required
Solve
One-eighth means 1/8
Three-elevenths means 3/11
So, mathematically; the above expression is represented as thus:
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
To solve this, we simply multiply the numerator and the denominator together.
After multiplying these together, the next is to check if the resulting can be simplified
If yes,we simplify it and if otherwise, we live it like that.
So,
[tex]\frac{1}{8} * \frac{3}{11}[/tex]
[tex]=\frac{1 * 3}{8 * 11}[/tex]
[tex]= \frac{3}{88}[/tex]
At this point, the fraction can't be simplified any further.
Hence,
[tex]\frac{1}{8} * \frac{3}{11} = \frac{3}{88}[/tex]

Answer:
C
Step-by-step explanation:
you were told to draw a graph
f(x) or y is 4 when x less than or equal to 3. so you must draw straight horizontal line at y = 4 start from x = 3 to the left
(fx) or y is 2 when x bigger than 3. so, 3 is not included. so you must draw straight horizontal line at y = 2 start from x = 3 to the right with empty circle first (it means 3 not included)
The average reading score on a certain test is given by y=0.150x +255.34 where x is the number of years past 1970 . In what year would the average reading score be 259.24 if this model was accurate
Answer:
The average was 259.24 in 1996.
Step-by-step explanation:
In order to find the year that the average, "y", is 259.24 we need to apply this value on the given expression, as done below:
[tex]259.24 = 0.15*x + 255.34\\0.15*x = 259.24 - 255.34\\0.15*x =3.9\\x = \frac{3.9}{0.15}\\x = 26[/tex]
The average was 259.24 after 26 years, therefore it was in 1996.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. What is the output of the function f(x) = x + 21 if the input is 4? When the input is 4, the output of f(x) = x + 21 is .
Answer:
When the input is 4, the output of f(x) = x + 21 is 25.
Step-by-step explanation:
The given function is
[tex]f(x)=x+21[/tex]
Here, x is input and f(x) is output.
We need to find the output of the given function f(x) if the input is 4.
Substitute x=4 in the given function.
[tex]f(4)=4+21[/tex]
[tex]f(4)=25[/tex]
So, the output value is 25.
When the input is 4, the output of f(x) = x + 21 is 25.
