At the international space station, a chemist cooled his solution for 20min at a steady rate. The temperature of his solution dropped from +5 degrees Celsius to -55 degrees Celsius. What was the temperature change per minute?
The temperature change per minute during the 20-minute cooling period at a steady rate was -3 degrees Celsius per minute.
To calculate the temperature change per minute, we need to determine the difference in temperature and divide it by the time in minutes. In this case, the initial temperature was +5 degrees Celsius, and the final temperature was -55 degrees Celsius. The temperature change is the difference between these two values: -55 - (+5) = -60 degrees Celsius.
Since the cooling period lasted for 20 minutes, we divide the temperature change by the time: -60 degrees Celsius / 20 minutes = -3 degrees Celsius per minute.

When rolling two standard number cubes, what is the probability of rolling at least one six?
Group of answer choices
6/36
11/36
1/36
12/36
The probability of rolling at least one six when rolling two standard number cubes is 11/36.
To determine the probability, we first need to find the total number of possible outcomes when rolling two standard number cubes. Each cube has 6 faces, numbered from 1 to 6, so the total number of outcomes is 6 multiplied by 6, which equals 36.
Next, we need to calculate the number of favorable outcomes, which is the number of outcomes where at least one six is rolled. There are three possible scenarios:
Rolling a six on the first cube and any number on the second cube.
Rolling any number on the first cube and a six on the second cube.
Rolling a six on both the first and second cubes.
For each scenario, there is a 1/6 probability of rolling a six on a single cube. Therefore, the number of favorable outcomes is 1 + 1 + 1 = 3.
Finally, we divide the number of favorable outcomes (3) by the total number of possible outcomes (36) to calculate the probability:
Probability = Number of favorable outcomes / Total number of possible outcomes
= 3 / 36
= 1 / 12
= 11 / 36
Therefore, the probability of rolling at least one six when rolling two standard number cubes is 11/36.

The heights of the Lincoln High School Boys have a normal distribution with a mean height of 70 inches and a standard deviation of 4 inches
Therefore, the probability of a randomly chosen boy having a height less than 66 inches is 15.87%.
The heights of the Lincoln High School boys have a normal distribution with a mean height of 70 inches and a standard deviation of 4 inches. The probability of a randomly chosen boy having a height less than 66 inches is asked. We can solve this problem by using the standard normal distribution or z-distribution. The standard normal distribution has a mean of zero and a standard deviation of one. It is a normal distribution that has been transformed to have a mean of 0 and a standard deviation of 1. Therefore, we must convert the given values into z-scores. The z-score formula is:
z = (x - μ) / σ
where x is the value we are interested in, μ is the mean, and σ is the standard deviation.
In this problem, we want to find the probability that a boy's height is less than 66 inches, so x = 66. Using the formula above, we get:
z = (66 - 70) / 4 = -1
This means that a boy's height of 66 inches is one standard deviation below the mean. To find the probability of a boy having a height less than 66 inches, we look up the area to the left of the z-score of -1 in the standard normal distribution table. The table gives us the probability of a randomly chosen boy having a height less than 66 inches as 0.1587 or 15.87%.

Aaron ate ½ as much pizza as David. If Aaron ate ¼ of a pie, what fraction of the pie did David eat? Write and solve an equation.
Given that Aaron ate half as much pizza as David and Aaron ate 1/4 of a pie, we can determine the fraction of the pie David ate by setting up an equation and solving for it.
Let's assume that David ate x amount of pizza, which represents the fraction of the pie he consumed. Since Aaron ate half as much pizza as David, we can express Aaron's portion as (1/2)x. We are also given that Aaron ate 1/4 of a pie, so we can set up the equation:
(1/2)x = 1/4
To solve for x, we can multiply both sides of the equation by 2 to eliminate the fraction:
2 * (1/2)x = 2 * (1/4)
x = 1/2
Therefore, David ate 1/2 of the pie. This means that Aaron ate half as much pizza as David, while David consumed the remaining half of the pie.

If a straight angle is split into two angles and one of
them is twice as big as the other, what are the two
angles
When a straight angle is split into two angles, the sum of those angles is 180 degrees because a straight angle measures 180 degrees.
Let's assume that the smaller angle is represented by x. Since the larger angle is twice as big as the smaller angle, it can be represented as 2x. Therefore, the sum of the two angles can be expressed as:
x + 2x = 180 degrees This simplifies to 3x = 180 degrees.
Dividing both sides by 3, we get: x = 60 degrees.
This means that the smaller angle is 60 degrees and the larger angle is twice as big, or 2(60) = 120 degrees.
Therefore, the two angles are 60 degrees and 120 degrees.

Industrial revolution dbq prompt: identify the issues raised by the growth of Manchester and analyze the reaction of those issues over the course of the nineteenth century
The growth of Manchester during the Industrial Revolution gave rise to several issues that had significant social, economic, and environmental implications.
As a result, reactions to these issues emerged and evolved over the course of the nineteenth century.
One major issue raised by the growth of Manchester was poor working and living conditions for the working class. Rapid industrialization led to the establishment of large factories and mills, which attracted workers from rural areas. These workers often faced long working hours, low wages, and hazardous working conditions. They lived in overcrowded and unsanitary slums, lacking proper housing, sanitation, and access to basic amenities. These harsh conditions resulted in widespread poverty, disease, and social unrest.
In response to these issues, various movements and reforms emerged throughout the nineteenth century. The labor movement gained momentum as workers organized themselves to demand better working conditions, higher wages, and shorter hours. The formation of trade unions aimed to protect workers' rights and negotiate with employers. Additionally, reformers such as Robert Owen and the Chartists advocated for social and political reforms to address the plight of the working class.
Another issue that arose with the growth of Manchester was environmental degradation. The rapid expansion of industries led to pollution of air and water sources. Factories emitted smoke and pollutants, contributing to air pollution and poor air quality. Rivers and streams became contaminated with industrial waste and sewage, leading to water pollution and health hazards.
As awareness of these environmental issues grew, there were efforts to address them. The establishment of legislation and regulations aimed to control pollution and improve public health. For example, the Alkali Act of 1863 imposed restrictions on the emission of harmful gases from factories. These measures, although limited, marked the beginning of environmental consciousness and attempts to mitigate the negative impact of industrialization.
Furthermore, the growth of Manchester highlighted class divisions and inequalities. The wealthy factory owners and industrialists thrived while the working class suffered. This socioeconomic divide led to social tensions and movements advocating for greater equality and social reforms.
Throughout the nineteenth century, the issues raised by the growth of Manchester prompted a gradual transformation in society. Reactions to these issues ranged from grassroots movements to legislative reforms. Although progress was often gradual and incremental, the recognition of the hardships faced by the working class and the need for improved working conditions, social reforms, and environmental conservation laid the groundwork for future advancements in labor rights, social equality, and environmental protection.

Dylan's Velocity is 12 feet per second
Ryan's velocity is -10 feet per second
When is each person at the position -10 feet from the meeting place use each answer in a complete sentence in the context of the problem
Dylan is at a position 10 feet from the meeting place after 5/6 seconds, while Ryan is not at a position 10 feet from the meeting place.
To find when each person is at a position 10 feet from the meeting place, we can use their velocities and the concept of relative motion.
For Dylan:
Dylan's velocity is 12 feet per second. Since Dylan is walking towards the meeting place, his velocity is positive. To find when Dylan is at a position 10 feet from the meeting place, we can set up the following equation:
Distance = Velocity × Time
10 = 12t
Solving for t, we divide both sides of the equation by 12:
t = 10/12
t = 5/6 seconds
Therefore, Dylan is at a position 10 feet from the meeting place after 5/6 seconds.
For Ryan:
Ryan's velocity is -10 feet per second. Since Ryan is walking in the opposite direction, his velocity is negative. To find when Ryan is at a position 10 feet from the meeting place, we can set up the following equation:
Distance = Velocity × Time
10 = (-10)t
Solving for t, we divide both sides of the equation by -10:
t = 10/(-10)
t = -1 second
Since time cannot be negative in this context, we can conclude that Ryan is not at a position 10 feet from the meeting place.
In summary, Dylan is at a position 10 feet from the meeting place after 5/6 seconds, while Ryan is not at a position 10 feet from the meeting place.

• Write the distance
The midpoint of the line segment connecting two points can be found by averaging their corresponding coordinates. Therefore, to obtain the midpoint of line BC, we add the coordinates of B and C and divide by 2.
Midpoint of line BC is given by:
\[\left(\frac{-1-3}{2},\frac{1-1}{2},\frac{2+0}{2}\right)=(-2,0,1)\]
The length of line AD is found by using the distance formula, which is given as:
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}\]
Thus, we need to find the coordinates of point D and A to determine the length of AD. The coordinates of D are the average of the coordinates of B and C.
\[\left(\frac{-1-3}{2},\frac{1-1}{2},\frac{2+0}{2}\right)=(-2,0,1)\]The coordinates of A are (1,2,-1).
The distance between A and D is found by substituting these values into the distance formula:
\[d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}\] \[d=\sqrt{(1-(-2))^2+(2-0)^2+(-1-1)^2}\] \[d=\sqrt{(3)^2+(2)^2+(-2)^2}\] \[d=\sqrt{9+4+4}\] \[d=\sqrt{17}\]

The amount of cleaning solution a company fills its bottles with has a mean of of 33\,\text{fl oz}33fl oz33, start text, f, l, space, o, z, end text and a standard deviation of 1.5\,\text{fl oz}1.5fl oz1, point, 5, start text, f, l, space, o, z, end text. The company advertises that these bottles have 32\,\text{fl oz}32fl oz32, start text, f, l, space, o, z, end text of cleaning solution.
What will be the mean and standard deviation of the distribution of excess cleaning solution, in milliliters?
(1\,\text{fl oz}(1fl ozleft parenthesis, 1, start text, f, l, space, o, z, end text is approximately 30\,\text{mL}.)30mL.)
To find the mean and standard deviation of the distribution of excess cleaning solution, we need to calculate the difference between the advertised amount of cleaning solution and the actual amount filled in the bottles.
1 fluid ounce (1 fl oz) is approximately equal to 30 milliliters (30 mL), so we can convert the measurements to milliliters for consistency.
Mean:
The mean of the distribution of excess cleaning solution can be calculated as the difference between the mean amount of filling (33 fl oz) and the advertised amount (32 fl oz), both converted to milliliters:
Mean = (33 - 32) fl oz * 30 mL/fl oz = 30 mL
Therefore, the mean of the distribution of excess cleaning solution is 30 milliliters.
Standard Deviation:
The standard deviation of the distribution can be found using the formula for the propagation of uncertainty. Since the standard deviation of the filling amount is given as 1.5 fl oz, we convert it to milliliters as well:
Standard Deviation = 1.5 fl oz * 30 mL/fl oz = 45 mL
Therefore, the standard deviation of the distribution of excess cleaning solution is 45 milliliters.
In summary, the mean of the distribution of excess cleaning solution is 30 milliliters and the standard deviation is 45 milliliters.

A goalie's saves (⋅ ) and goals scored against (x) are shown. What percent of shots did the goalie save?
will name person with correct answer brainlest.
To determine the percentage of shots that the goalie saved, we need the actual numbers of saves and goals scored against the goalie. Since the specific values are not provided in the question, it is not possible to calculate the exact percentage.
However, I can explain the general process for calculating the percentage of savings.
To find the percentage of saves, we need to divide the number of saves by the total number of shots and then multiply by 100. The formula for calculating the percentage is:
Percentage of saves = (Number of saves / Total number of shots) * 100
For example, if the goalie made 30 saves out of 40 total shots, the calculation would be:
Percentage of saves = (30 / 40) * 100 = 75%
In this case, the goalie saved 75% of the shots.
Without the specific values of saves and shots, it is not possible to determine the exact percentage.

Can a diagonal of a parallelogram be congruent to one of its sides? Explain your answer.
(I need an actual explanation for this. Like, one I can write down, not just the answer. I will give Brainliest if the answer is actually helpful. )
No, the diagonal of a parallelogram cannot be congruent to one of its side.
Given data,
Let the parallelogram be represented as ABCD
Now , the diagonal is AC and BD
The opposing sides of a parallelogram are parallel and congruent. This implies that the length of every pair of opposing sides is the same.
The parallelogram's opposite sides would be equal in length if one of its diagonals were congruent to one of its sides. However, unless it is a rectangle or a rhombus, this goes against the definition of a parallelogram, which calls for opposing sides to be parallel but not equal in length.
Therefore, a parallelogram's diagonal cannot be congruent to one of its sides by definition.

One diameter makes ____________ parts of the circle .
One diameter makes two parts of the circle. A diameter is a chord that passes through the center of a circle. When a circle is divided into two halves by the diameter, each half is called a semicircle.
When a line segment that passes through the center of a circle is drawn, it is referred to as a diameter. A circle has a diameter, its longest chord, and its endpoints lie on the circle itself. The midpoint of the diameter is the center of the circle. A diameter divides a circle into two equal parts, known as semicircles. A semicircle is the region enclosed by the arc and the diameter.
The semicircle's area is half the circle from which it was derived. The diameter is the longest chord that a circle has, and it passes through the center of the circle. The diameter divides the circle into two halves. Every chord's perpendicular bisector passes through the center of the circle. This property of the diameter is also applicable to chords. The perpendicular bisector of the chord passes through the circle's center, and the chord is divided into two equal parts.
Therefore, one diameter makes two parts of the circle. A diameter is a chord that passes through the center of a circle. When a circle is divided into two halves by the diameter, each half is called a semicircle.

Angles 1 and 2 are vertical angles. If angle 1 is 62 degrees, what is the measurement of angle 2?
If angles 1 and 2 are vertical angles, then they are congruent. If angle 1 measures 62 degrees, then angle 2 will also measure 62 degrees.
Vertical angles are formed by the intersection of two lines. They are opposite each other and have equal measures. In this case, if angle 1 measures 62 degrees, angle 2 will also measure 62 degrees because they are vertical angles.
This property of vertical angles can be understood based on the concept of a straight line. When two lines intersect, they form two pairs of vertical angles. Since a straight line measures 180 degrees, each pair of vertical angles will have a total measure of 180 degrees, and thus, each angle within the pair will have the same measure. Therefore, if angle 1 measures 62 degrees, angle 2 will also measure 62 degrees.

Circle plus circle refers to the sum of the areas of two circles. The formula for the area of a circle is given as: $$A=πr^2$$ where A is the area of the circle and r is its radius. To find the sum of the areas of two circles, we simply add their respective areas.
Therefore, the value of circle plus circle is given by the formula: $$\text{Circle plus Circle} = πr_1^2 + πr_2^2$$ where r1 and r2 are the radii of the two circles respectively. If the values of the radii are provided, then we can substitute them in the above formula to find the value of circle plus circle. To find the value of circle plus circle, we need to add the areas of two circles. The area of a circle is given by the formula A = πr² where A is the area of the circle and r is the radius. Therefore, the formula for the value of circle plus circle is given by Circle plus Circle = πr1² + πr2² where r1 and r2 are the radii of the two circles respectively. As we already know that a circle is a geometric figure having no end. It has many properties. One of its properties is that its area can be measured. When we talk about the area of a circle, we are referring to the region enclosed by it. The area of a circle is given by the formula: A = πr², where A is the area of the circle and r is its radius.
