Johnny read 30 pages on Monday. On Tuesday he read 1/8 of the book. On Wednesday he read the remaining 1/4. How many pages did he read in total?To find out how many pages Johnny read in total, we need to first determine the total number of pages in the book. We know that he read 1/8 of the book on Tuesday and the remaining 1/4 on Wednesday. So we can add these two fractions to find out the total fraction of the book that he read:1/8 + 1/4 = 3/8Now we know that Johnny read 3/8 of the book. We can use this information to set up a proportion to find out how many pages he read in total:3/8 = x/total number of pagesTo solve for x, we can cross-multiply and simplify:3/8 * total number of pages = xMultiply both sides by 8/3:total number of pages = x * 8/3Now we need to find out what x is. We know that Johnny read 30 pages on Monday, which is 1/8 of the total number of pages. So we can use this information to set up another proportion:1/8 = 30/total number of pagesTo solve for the total number of pages, we can cross-multiply and simplify:1/8 * total number of pages = 30Multiply both sides by 8:total number of pages = 240Now we can substitute this value for the total number of pages in our previous equation to find out how many pages Johnny read in total:total number of pages = x * 8/3240 = x * 8/3Multiply both sides by 3/8:x = 90Therefore, Johnny read a total of 30 + 90 = 120 pages.

A math class is set up to have assignments worth 45%, quizzes worth 40% and the final exam is worth the rest of the grade. If Serena has 78% on assignments and 65% on quizzes and 96% on the final, what is her overall grade to 2 decimal places?
Serena's overall grade in the course is 75.5%. It's important to note that in a weighted grading system like this, the final exam is often a major determinant of the final grade.
To calculate Serena's overall grade, we need to first determine the weight of the final exam. We know that the assignments are worth 45% and the quizzes are worth 40%, which leaves 100% - 45% - 40% = 15% for the final exam.
Next, we can calculate Serena's grade for each component of the course. Her grade for assignments is 78% and her grade for quizzes is 65%. We can calculate her grade for the final exam by multiplying her score of 96% by the weight of the final, which is 15%:
Final grade = (0.45 * 78%) + (0.4 * 65%) + (0.15 * 96%)
Final grade = 35.1% + 26% + 14.4%
Final grade = 75.5%
Therefore, Serena's overall grade in the course is 75.5%. It's important to note that in a weighted grading system like this, the final exam is often a major determinant of the final grade. In this case, Serena's strong performance on the final exam helped to boost her overall grade, even though her scores on the assignments and quizzes were not as high. It's also worth noting that this calculation assumes that all assignments, quizzes, and the final exam were weighted equally within their respective categories (i.e., each assignment was worth the same percentage of the assignment grade).

You buy 4 small candles and 1 large candle for $18. Your friend buys 5 small candles
and 2 large candles for $27. What is the cost of each small candle? of each large candle?
Answer: The cost of each small candle is $3 and the cost of each large candle is $6.
Step-by-step explanation:
Let's use variables to represent the cost of each small candle and each large candle. Let's call the cost of each small candle "x" and the cost of each large candle "y".
We can set up two equations based on the information given:
4x + 1y = 18 (equation 1)
5x + 2y = 27 (equation 2)
We can solve for one variable in terms of the other by using one equation to eliminate one variable. Let's solve for "y" in terms of "x" by multiplying equation 1 by 2 and subtracting it from equation 2:
5x + 2y = 27
(8x + 2y = 36)
-3x = -9
Dividing both sides by -3, we get:
x = 3
Now that we know the cost of each small candle is $3, we can substitute that value into one of the equations to solve for the cost of each large candle. Let's use equation 1:
4x + 1y = 18
4(3) + 1y = 18
12 + y = 18
y = 6
Therefore, the cost of each small candle is $3 and the cost of each large candle is $6.
four students use different instruments to measure the length of the same pen. which measurement implies the greatest precision?
If four students use different instruments to measure the length of the same pen, the measurement which implies the greatest precision is 160.0 mm. Correct option is A.
To determine which measurement implies the greatest precision, we need to look at the number of significant figures in each measurement. The greater the number of significant figures, the greater the precision of the measurement.
In this case, we have four measurements:
(a) 160.0 mm
(b) 16.0 cm
(c) 0.160 m
(d) 0.00016 km
We can see that all of these measurements represent the same length in different units, and they are all written with the same number of decimal places. However, the number of significant figures is different for each measurement.
Measurement (a) has four significant figures, while measurements (b), (c), and (d) each have three significant figures. Therefore, measurement (a) implies the greatest precision, since it has the most significant figures.
So, the answer is (a) 160.0 mm, which implies the greatest precision among the given measurements.

how many simple paths of nonzero length are there in a tree with vertices, where ? (regard two simple paths as the same if they have the same edges.)
there are n(n-1)(n-2)/2 simple paths of nonzero length in a tree with n vertices, where two simple paths are regarded as the same if they have the same edges.
In a tree with n vertices, there are (n-1) edges, since a tree is a connected acyclic graph.
To count the number of simple paths of nonzero length in the tree, we can consider each vertex as a starting point for a path and count the number of possible paths from that vertex.
Starting from any vertex, there are at most (n-1) paths that can be formed by moving to any of the neighboring vertices. From each of these neighboring vertices, there are at most (n-2) paths that can be formed by moving to a new neighboring vertex (excluding the vertex that was just visited).
This process can be continued until there are no more vertices to visit. However, to avoid counting the same path twice, we should only consider paths that do not backtrack on themselves.
Therefore, the total number of simple paths of nonzero length in the tree is the sum of all simple paths that start from each vertex:
(number of paths starting from vertex 1) + (number of paths starting from vertex 2) + ... + (number of paths starting from vertex n)
Using the reasoning above, we can see that the number of paths starting from each vertex is at most (n-1) * (n-2), since each path can visit at most (n-2) additional vertices after the starting vertex, and there are at most (n-1) vertices to choose from as the next vertex on the path.
Therefore, the total number of simple paths of nonzero length in the tree is at most n(n-1)(n-2).
However, we have counted each simple path twice (once in each direction), so the actual number of distinct simple paths of nonzero length is half of this maximum value, which is:
n(n-1)(n-2)/2
So, there are n(n-1)(n-2)/2 simple paths of nonzero length in a tree with n vertices, where two simple paths are regarded as the same if they have the same edges.

The distance from Elena's chin to the top of her head is 150
mm in an image. For a U.S. passport photo, this
measurement needs to be between 25 mm and 35 mm.
The height of the image after being scaled down by 80% three times is 76.8mm, which is not within the required range for a U.S. passport photo.
What is scaling?Scaling is the process of increasing or decreasing the size of a picture by dividing or multiplying its dimensions. An picture is expanded when it is scaled up, and its size is decreased when it is scaled down. An picture is affected by scaling when its size and, consequently, appearance, are altered. An picture may become pixelated or fuzzy if it is scaled up or down excessively, and information may be lost if it is scaled down too much. The aspect ratio of an image—the proportion of its width to its height—can also be impacted by scaling. The picture could look stretched or squished if the aspect ratio is modified.
Given that the image is 150 mm in height.
Thus, 80% of the image is:
150mm x 0.8 = 120mm
The scaling is performed 3 times, thus:
120mm x 0.8 = 96mm
96mm x 0.8 = 76.8mm
Hence, the height of the image after being scaled down by 80% three times is 76.8mm, which is within the required range for a U.S. passport photo.

2 1/4 pounds of turkey is equivalent to 9/4 pounds of turkey.
2/3 pound of cheddar cheese is equivalent to 0.67 pounds of cheddar cheese.
So the cost of each item is:
American cheese: (4/3) x $6.99 = $9.32 (rounded to the nearest cent)
Turkey: (9/4) x $5.99 = $13.48 (rounded to the nearest cent)
Cheddar cheese: 0.67 x $3.99 = $2.67 (rounded to the nearest cent)

What is the vertical distance between (2, 11/3)
and (2, - 4/3)?
The vertical distance between (2, 11/3) and (2, -4/3) is -5 units.
Define distance formulaThe distance formula is a mathematical equation used to find the distance between two points in a plane. It is derived from the Pythagorean theorem and is expressed as:
d = √((x₂- x₁)²+ (y₂ - y₁)²)
The distance formula can also be extended to three-dimensional space by adding an additional term to the equation.
The two points (2, 11/3) and (2, -4/3) have the same x-coordinate, which means they lie on a vertical line. To find the vertical distance between these two points, we simply subtract their y-coordinates:
Vertical distance = (y-coordinate of second point) - (y-coordinate of first point)
= (-4/3) - (11/3)
= -15/3
= -5
Therefore, the vertical distance between (2, 11/3) and (2, -4/3) is -5 units. Since this is a negative value, it means that the second point is located 5 units below the first point.
