Mrs. Henry bought books during the summer. She bought 5 books for $12.00, 6 books for $10.00, and 4 books for $8.00. What is the average (mean) amount she spent for each book?Answer options with 5 optionsA.$4.00 per bookB.$3.25 per bookC.$3.00 per bookD.$2.75 per bookE.$2.00 per book
Answer: $60.00 (5 books), $60.00 (6 books), $32.00 (4 books) is the data set. The answer, when used in a calculator, is 3.3777777777. From this result, I would say B or $3.25 per book.
The correct answer is option B) $2.75.
How to find mean?
The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.
By applying the formula
= 40/15
≅ 2.75
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

What is the quotient?
Answer:
4 x 10^12
Step-by-step explanation:
4,000,000,000,000
The quotient is 4*10^12.
(6*10^8) / (1.5*10^-4) = 4*10^(8-(-4)) = 4*10^12
6 divided by 1.5 is 4. When the base is the same, and you're dividing, you subtract the exponents. They both have a base of 10, so 8-(-4) gives you 12. So, it would be 10^12.

Craig bought 96 rolls or toilet paper for 48 dollars. What is the cost of a single
roll of toilet paper?
dollars
Check
Explain
HELP ME PLEASE
Final answer:
The cost of a single roll of toilet paper is $0.50, calculated by dividing the total cost of $48 by the number of rolls which is 96.
Explanation:
To find the cost of a single roll of toilet paper, we need to divide the total cost by the number of rolls. Craig bought 96 rolls of toilet paper for $48.
To calculate the cost per roll, we use the formula:
Cost per roll = Total cost / Number of rolls
So,
Cost per roll = $48 / 96 rolls
Cost per roll = $0.50 per roll
Therefore, the cost of a single roll of toilet paper is $0.50.

ms knight wants to throw a pizza party for all the 7th graders.in a random sample 13 ou of 20 7th graders preferred peperonie pizza the other 7 preferred cheeze. Based on the data out of 400 total 7th graders aproaxmently how many prefer peperoni
To estimate how many out of 400 seventh graders prefer pepperoni based on the sample, a proportion is used, resulting in approximately 260 students preferring pepperoni pizza.
Explanation:Ms. Knight wants to throw a pizza party for the seventh graders, and in a random sample, 13 out of 20 seventh graders preferred pepperoni pizza. To estimate how many out of 400 seventh graders would prefer pepperoni, we use a proportion. The proportion of students who prefer pepperoni in the sample is 13/20. To find the number who would prefer pepperoni out of 400, we set up a cross-multiplication:
13/20 = x/400Solving this equation for x (the number of 7th graders who prefer pepperoni out of 400) gives us:
20x = 13 * 40020x = 5200x = 5200 / 20x = 260So, approximately 260 seventh graders would prefer pepperoni pizza out of 400 based on the sample data.
Solve the equation

The answer is
Answer: 1
Step-by-step explanation:
(16+12x)=28
Since 4is a common factor in both terms we take out 4
4(4+3x)=28
Now take 4 to the other side
4+3x = 28/4 = 7
Similarly
3x = 7-4 =3
We end up with 3x=3

in the diagram below chords AB and CD intersects at E. If mAC=72 and mAEC=58. how many degrees are in mDB?
Answer:
44°
Step-by-step explanation:
∠ DEB and ∠ AEC are vertical and congruent
Thus ∠ DEB = 58°
The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] (DB + AC ) = 58° ( multiply both sides by 2 )
DB + AC = 116°, that is
DB + 72° = 116° ( subtract 72° from both sides )
DB = 44°
Answer:
Hey, and also, The Answer to Your question is 44 Degrees.
Step-by-step explanation:
∠ DEB and ∠ AEC are vertical and congruent
Thus ∠ DEB = 58°
The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is
(DB + AC ) = 58° ( multiply both sides by 2 )
DB + AC = 116°, that is
DB + 72° = 116° ( subtract 72° from both sides )
DB = 44°...... Stay safe Guys.
A circle has the equation (x+11)2+(y+6)2=324.
What are the coordinates of the center and the length of the radius?
The coordinates of the center are (11,6), and the length of the radius is 18 units.
The coordinates of the center are (−11,−6), and the length of the radius is 324 units.
The coordinates of the center are (11,6), and the length of the radius is 324 units.
The coordinates of the center are (−11,−6), and the length of the radius is 18 units.
Answer:
The centre is (-11, -6) and the radius = 18 units.
(Option 4).
Step-by-step explanation:
If we compare this with the standard form
(x - h)^2 + (y - k)^2 = r^2
- we see that the center is (-11, -6) and the radius id √324.
The center of the circle is at (−11, −6) and the radius is 18 units.
Explanation:The equation of a circle in general form is (x - h)^2 + (y - k)^2 = r^2 where (h, k) are the coordinates of the center of the circle and r is the radius. Given the equation (x + 11)^2 + (y + 6)^2 = 324, we can see that it is in a similar form but with a positive sign in the brackets. This implies that the center of the circle is at (−11, −6) and that the radius is the square root of 324, which is 18 units.

Write the first four terms of the recursive sequence: If a1=8 and an=a(n-1) -6
Is the recursive sequence arithmetic or geometric? Explain.
Answer:
8, 2, -4, -10.
Step-by-step explanation:
Each term (except the first one) is obtained by subtracting 6 from the previous one - that is what an = a(n -1) -6 means.
First term = a1 = 8 , so the second term = 8-6 = 2.
The first 4 terms are 8, 2, -4, -10.
This is an arithmetic sequence as there is a common difference of -6.

im not sure on how i am supposed to do this
Answer:
BC=15.01
Step-by-step explanation:
Line segment BC can also be represented by '?'. To solve for BC, find the value of '?'
Use the tangent ratio:
[tex]tangentX=\frac{opposite}{adjacent}[/tex]
Because you need the value opposite the given angle and you are given the length of the side adjacent the given angle (hypotenuse does not count as the adjacent side, EVER (btw)). Let 65° be X and let x replace'?'.Insert the appropriate values:
[tex]tan65=\frac{x}{7}[/tex]
Solve by isolating x. Multiply 7 to both sides:
[tex]7*(tan65)=7*(\frac{x}{7})\\\\7*tan65=x\\\\x=7*tan65[/tex]
Insert this equation into a calculator:
[tex]x=15.0115...[/tex]
Round to the nearest hundredth:
[tex]x=15.01[/tex]
So, BC is 15.01
Finito.

Don has an album that holds 500 stamps. Each page of the album holds 5 stamps. If 13% of
the album is empty, how many pages are filled with stamps?
pages are filled with stamps?
Answer:
87 pages are filled with stamps.
Step-by-step explanation:
We need to know how many stamps are in the album. Since it can hold 500 but is missing 13%, we can say that it is 87% (100-13=87) complete.
500*0.87=435
The album has 435 stamps.
A page can hold 5 stamps. Thus, 435/5=87
To find out how many stamp album pages are filled, calculate the total number of album pages, determine the number of empty stamps at 13%, and subtract the number of empty pages from the total to get 87 filled pages.
The mathematics problem presented asks how many pages of a stamp album are filled with stamps if 13% of the album is empty. To solve this, we need to calculate the total number of stamps that can fit in the album and determine how many stamps equivalent to 13% of the album are missing. With 500 stamps able to fit in the album and each page holding 5 stamps, we can first find out the total number of pages in the album.
Total number of pages = Total stamps / Stamps per page = 500 / 5 = 100 pages
Next, we calculate 13% of the total number of stamps to find out how many stamps are missing:
Number of empty stamps = Total stamps [tex]\times[/tex] 0.13 = 500 [tex]\times[/tex] 0.13 = 65 stamps
Now, we find out the number of empty pages:
Number of empty pages = Empty stamps / Stamps per page = 65 / 5 = 13 pages
Thus, the number of filled pages:
Total pages - Empty pages = 100 - 13 = 87 filled pages.
