The substance that has changed the most over time from its original plant material is the drug, opium. Opium is a narcotic substance obtained from the poppy plant and has been used as a painkiller for thousands of years. Over time, opium has undergone several transformations to become a more potent substance. The most significant change occurred when it was processed to produce morphine, a much stronger and more addictive substance. Morphine was first isolated from opium in 1804 by the German pharmacist Friedrich Sertürner. Since then, scientists have discovered how to further modify morphine to create an even more potent substance known as heroin.
Heroin is a highly addictive drug that has become a major public health problem. It is derived from morphine, which is derived from opium. The process of converting opium into heroin involves several chemical steps, which are illegal and extremely dangerous. This process often involves the use of toxic chemicals, such as hydrochloric acid and acetic anhydride, which can cause severe health problems and even death. Opium, morphine, and heroin are all examples of substances that have been changed significantly from their original plant material. However, the changes that have occurred over time have had serious consequences for public health and have led to a major epidemic of addiction and overdose deaths.

mile?
A.1/2 of an hour
B. 2/5 of an hour
C. 1/3 of an hour
D. 2/3 of an hour
Emily can walk 3/4 of a mile in 1/4 of an hour. At the same rate, time taken to walk 1 mile =1/3 of an hour.
Mathematical representation
We know that, Emily can walk 3/4 of a mile in 1/4 of an hour.
Meaning,
Time taken to walk 3/4 of a mile = 1/4 of an hour
Distance covered = 3/4 mile
We need to find the time taken by Emily to walk 1 mile.
The rate is defined as the distance covered in unit time. So,
Rate = Distance / Time
We know that Rate of Emily = 3/4 ÷ 1/4
= 3/4 × 4/1
= 3 miles/hour
The rate of walking is 3 miles/hour.
Now we can find the time taken to walk 1 mile using rate formula.
Distance = Rate × Time
We have to walk 1 mile and the rate of walking is 3 miles/hour.
Time = Distance / Rate
Time taken to walk 1 mile = 1 / 3 = 1/3 hour.

We often read that iq scores for large population are centered at 100.What percent of these 78 students have scores above 100?
It is not possible to determine the percentage of students with scores above 100 without additional information, such as the mean and standard deviation of the IQ scores of the population.
To determine the percentage of students with scores above 100, we need to know the mean and standard deviation of the IQ scores of the population. IQ scores are standardized such that the average score is set to 100, with a standard deviation of 15. However, without information about the distribution of the scores, it is not possible to provide an accurate percentage.
Assuming the distribution of IQ scores follows a normal distribution, we can use a table or a statistical calculator to estimate the percentage. For example, if we know the mean and standard deviation of the IQ scores, we can calculate the z-score for an IQ score of 100. The z-score measures the number of standard deviations a particular score is away from the mean.
Once we have the z-score, we can consult a standard normal distribution table or use a statistical calculator to find the corresponding percentage of scores above the given z-score. This percentage represents the proportion of students with IQ scores above 100.

Maija is building a square sandbox with sides 2 feet long. She wants to put sand 1.55 feet deep in the box. How much sand should Maija order?
To calculate the amount of sand Maija should order, we need to find the volume of the sandbox. The sandbox is in the shape of a cube, so its volume is determined by multiplying the length, width, and height.
Given that the sides of the square sandbox are 2 feet long and the desired depth of the sand is 1.55 feet, we can calculate the volume as follows:
[tex]\[ \text{Volume} = \text{Length} \times \text{Width} \times \text{Height} \][/tex]
Since all sides of the sandbox are equal in length (2 feet), the formula simplifies to:
[tex]\[ \text{Volume} = \text{Side}^3 \][/tex]
Substituting the values:
[tex]\[ \text{Volume} = 2 \, \text{ft} \times 2 \, \text{ft} \times 1.55 \, \text{ft} \][/tex]
[tex]\[ \text{Volume} = 6.2 \, \text{cubic feet} \][/tex]
Therefore, Maija should order 6.2 cubic feet of sand for her sandbox.

Leo made a 69, 84, 67, and an 81 on the first four tests. What score would he have to make on the 5th test in order to make at least a B in the course? Based on your answer, is it likely that Leo will make a B? Why or why not?
Leo would need to score at least 99 on the 5th test to achieve at least a B in the course. The likelihood of Leo making a B would depend on his individual abilities, preparation, and performance on the 5th test.
To determine what score Leo would need on the 5th test to achieve at least a B in the course, we first need to know the grading scale or criteria for the course. Different educational institutions and instructors may use different grading scales, so without that information, it is not possible to provide an exact answer.
However, assuming a common grading scale where:
A: 90-100
B: 80-89
C: 70-79
D: 60-69
F: Below 60
We can calculate the average score Leo needs to achieve a B. To find the average, we sum up the scores and divide by the total number of tests:
(69 + 84 + 67 + 81 + x) / 5 >= 80
Simplifying the equation:
301 + x >= 400
x >= 400 - 301
x >= 99
Therefore, Leo would need to score at least 99 on the 5th test to achieve at least a B in the course.
As for whether it is likely that Leo will make a B, it depends on various factors. If Leo has consistently performed well in the course and has a history of earning high scores on tests, it is possible that he can achieve a score of 99 or higher on the 5th test. However, if Leo has struggled in the course or has not performed well on previous tests, it may be challenging for him to score high enough on the 5th test to reach a B.

Now only £78
How much was the phone before the discounted price?
The original price of the refurbished phone before the 35% discount was £120. If a refurbished phone is sold at a 35% discount with a final price of £78.
To find the original price of a refurbished phone before the discount of 35%, let's use the following formula:
discount = original price - discounted price
35% of the original price can be represented as 0.35 times the original price. This will result in the equation below:
0.35x = original price - 78
Where x is the original price. So, to find the value of x, we can rearrange the equation to get:
0.35x + 78 = original price
Now we substitute the given values into the equation above:
0.35x + 78 = original price
0.35x + 78 = x - 44.1 (if x represents the original price)
Let's subtract 0.35x from both sides to isolate the x variable:
78 = 0.65x
Then, let's divide both sides by 0.65 to solve for x (the original price):

Santos takes the train into the city five days a week for work. For one work week he kept track of how many minutes the train ride was : 48,51,48,48,50
Calculate the mean median range in the range of the train ride times for the week
The mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes.
The mean, median, and range of Santos' train ride times for the week were as follows:
Mean: 49.4 minutes
The mean is calculated by adding up all the values and dividing the sum by the total number of values. In this case, the sum of the train ride times (48 + 51 + 48 + 48 + 50) is 245 minutes. Dividing this sum by the total number of days (5), we get the mean of 49.4 minutes.
Median: 48 minutes
The median is the middle value in a sorted list of numbers. To find the median, we arrange the train ride times in ascending order: 48, 48, 48, 50, 51. Since there is an odd number of values, the middle value is the median. In this case, the median is 48 minutes.
Range: 3 minutes
The range is the difference between the largest and smallest values in a set. To calculate the range, we subtract the smallest value (48 minutes) from the largest value (51 minutes). In this case, the range of the train ride times for the week is 3 minutes.
In summary, the mean train ride time for the week was 49.4 minutes, with a median of 48 minutes. The range of the train ride times was 3 minutes. These metrics provide insights into the average, central tendency, and variability of Santos' train rides throughout the week.

Suppose a chemist combines a 25% acid solution and a 50% acid solution to make 40 L of 45% acid solution. How many liters of each solution did she use? Use the blanks below to fill in your numerical answers.
__________ L of 50% solution; __________ L of 25% solution
To create a 40 L solution with a 45% acid concentration, a chemist combines a 25% acid solution and a 50% acid solution. Therefore, the chemist used 32 L of the 50% acid solution and (40 - 32) = 8 L of the 25% acid solution to create the 40 L solution with a 45% acid concentration.
Let's assume the chemist uses "x" liters of the 50% acid solution. Since the total volume of the mixture is 40 L, the remaining volume will be (40 - x) liters of the 25% acid solution.
The acid content in the 50% solution is 0.5x, while the acid content in the 25% solution is 0.25(40 - x).
To find the acid content in the final 45% solution, we multiply the acid concentration (0.45) by the total volume (40):
0.45 * 40 = 0.5x + 0.25(40 - x)
Simplifying the equation:
18 = 0.5x + 10 - 0.25x
Combining like terms:
0.25x = 8
Dividing both sides by 0.25:
x = 32
Therefore, the chemist used 32 L of the 50% acid solution and (40 - 32) = 8 L of the 25% acid solution to create the 40 L solution with a 45% acid concentration.

Cindy has scores of 72, 82, 83 and 89 on her Biology tests. The Final Exam counts as two tests and she will receive a C in the course if her average is from 77-84. What score must she receive on her Final Exam to earn a C in Biology?
Cindy has scores of 72, 82, 83 and 89 on her Biology tests. Cindy must score between 68 and 89 on her final exam to earn a C in Biology.
Cindy's current average score in Biology is:
(72 + 82 + 83 + 89) / 4 = 81.5
Since the final exam counts as two tests, we can calculate the total number of points Cindy can earn in the course as follows:
Total points = 4 tests + 2 tests = 6 tests
To earn a C in the course, her average score must be between 77 and 84. Let's assume she needs to score x on her final exam to achieve a C. Then her total points would be:
Total points = 72 + 82 + 83 + 89 + x + x
Simplifying this equation, we get:
Total points = 326 + 2x
To earn a C, Cindy's average score must be between 77 and 84. Therefore, we can set up an inequality:
77 <= (326 + 2x) / 6 <= 84
Multiplying both sides by 6, we get:
462 <= 326 + 2x <= 504
Subtracting 326 from all sides, we get:
136 <= 2x <= 178
Dividing by 2, we get:
68 <= x <= 89
Therefore, Cindy must score between 68 and 89 on her final exam to earn a C in Biology.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76. 9 Mbps. The complete list of 50 data speeds has a mean of x overbar equals17. 21 Mbps and a standard deviation of sequals 32. 78 Mbps. A. What is the difference between carrier's highest data speed and the mean of all 50 data speeds? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the carrier's highest data speed to a z score. D. If we consider data speeds that convert to z scores between minus 2 and 2 to be neither significantly low nor significantly high, is the carrier's highest data speed significant?
a) The difference between the carrier's highest data speed (76.9 Mbps) and the mean of all 50 data speeds (17.21 Mbps) is 59.69 Mbps.
b) To determine how many standard deviations the difference found in part (a) represents, we can use the formula: z = (x - μ) / σ, where z is the number of standard deviations, x is the data point, μ is the mean, and σ is the standard deviation. In this case, the difference of 59.69 Mbps can be divided by the standard deviation of 32.78 Mbps to find the number of standard deviations.
c) To convert the carrier's highest data speed (76.9 Mbps) to a z score, we use the formula: z = (x - μ) / σ. By substituting the values into the formula, we can calculate the z score.
d) If we consider data speeds that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, we can compare the z score calculated in part (c) with this range to determine if the carrier's highest data speed is significant. If the z score falls within the range of -2 to 2, it is not considered significantly low or significantly high.

What are the new diminsions of a 4x6 photo enlarged 2:3
Answer:
Step-by-step explanation:
To enlarge a 4x6 photo with a ratio of 2:3, we can multiply the dimensions of the photo by the enlargement ratio to find the new dimensions.
Original photo dimensions: 4 inches x 6 inches
Enlargement ratio: 2:3
To find the new dimensions, we can multiply the original dimensions by the enlargement ratio:
New width = 4 inches x 2 = 8 inches
New height = 6 inches x 3 = 18 inches
Therefore, the new dimensions of the enlarged photo would be 8 inches x 18 inches.

the line on the graph passes through points (0,6) and (3,0).a - what is the gradient of the line?b - what the gradient of the line perpendicular to this line?c - what is the equation for the line that passes through a and is perpendicular to ab?
a) The gradient of the line passing through the points (0,6) and (3,0) is -2. b) The gradient of the line perpendicular to this line is 1/2. c) The equation for the line passing through point a and perpendicular to the line ab can be determined using the point-slope form of a linear equation.
a) To find the gradient (slope) of the line passing through (0,6) and (3,0), we use the formula: gradient = (change in y) / (change in x). Substituting the coordinates, we get (-6) / (3-0) = -2.
b) The gradient of a line perpendicular to another line is the negative reciprocal of the original gradient. Therefore, the gradient of the line perpendicular to the given line is 1/2.
c) To find the equation of the line passing through point a and perpendicular to line ab, we can use the point-slope form of a linear equation: y - y1 = m(x - x1), where (x1, y1) is point a and m is the gradient of the perpendicular line. Substituting the values, we get y - 6 = (1/2)(x - 0), which simplifies to y = (1/2)x + 6.

There are 640 acres in a square mile, and 5280 feet in 1. 00 mile. What is the length in feet (to the nearest foot) of the side of a square having an area of 1. 00 acre?
The side lengt of the square is approximately 1839 feet.
How to find the side length?To find the length in feet of the side of a square with an area of 1.00 acre, we need to convert the acreage to square feet.
Given:
1 acre = 640 acres/mile² (640 acres in a square mile)
1 mile = 5280 feet (conversion factor from miles to feet)
To convert acres to square feet, we can multiply by the conversion factor:
1 acre = 640 acres/mile² * 1 mile² * 5280 feet
Simplifying the units:
1 acre = 640 * 5280 square feet
Now, to find the length of the side of the square, we can take the square root of the area:
Side length = √(1 acre * 640 * 5280 square feet)
Calculating:
Side length ≈ √(1 * 640 * 5280) ≈ √3379200 ≈ 1839.29 feet
Rounding to the nearest foot, the length of the side of the square with an area of 1.00 acre is approximately 1839 feet.
