John believes that the amount of sleep he gets the night before a test and his score on that test are inversely related. On his first exam, he got eight hours of sleep and scored 70 on the exam. To the nearest tenth, how many hours does john believe he must sleep the night before his second exam so that the average of his two exam scores is an 80?.
John will need to sleep for 10.3 hours before his second exam so that the
average of his two exam scores is an 80.
We were given
8 hours of sleep = 70
To get average of 80
70+ x = 80
2
Cross multiply:
70+x = 160
x= 160-70
= 90.
If 8 hours of sleep = 70
x hours of sleep = 90
Cross multiply
8× 90 = 70 × x
720 = 70x
x = 720/70
x = 10.2857
≈ 10.3 hours of sleep

Which correctly lists the three features shown in the photo? folds, strike-slip faults, and anticlines anticlines, synclines, and folds synclines, normal faults, and strike-slip faults normal faults, folds, and anticlines.
Anthe answer is A
Explanation:
The correct list of the three features shown in the photo are folds, strike-slip faults, and anticlines. The correct option is A.
What are folds?On a geological timescale, modern folds are those that first appeared in the Tertiary Period (between 65 million and 2.5 million years ago). Geological formations known as faults are the result of internal forces that are inclined or vertical (top-down).
The transcurrent fault, which is also known as a horizontal fault, develops when there is movement in the horizontal plane between two blocks.
It is more prevalent in regions where two tectonic plates converge since these zones also experience horizontal movement. When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Therefore, the correct option is A, folds, strike-slip faults, and anticlines.

Which image do you think best illustrates the tragedy of the fire? why? give at least three reasons for your choice in your response.
9-13 and 17
Pictures 9-13 actually show dead people, who died trying to escape the fire. These were people who had lives, families, etc. who never knew that an ordinary work day would turn tragic. The sheer number of people seen truly shows how horrific of an event this was, with their bodies being broken and lifeless.
17 shows the aftermath of the fire. What was once a busy, bustling workplace full of life was now lonely and deserted, with the ashes of equipment, clothing, and crushed memories. The scorched-black room and messy area really give off that "neglected and forgotten" feel. Even the officer contributes to the empty feel of the room, as he's the only one seen there, all alone.
Pictures 9 through 13 show actual deceased victims who perished while attempting to flee the fire. These were folks with families, lives, and other responsibilities who had no idea that a routine workday would end tragically.
What is Fire?The observable result of the combustion process, a unique kind of chemical reaction, is fire. It happens when some kind of fuel and atmospheric oxygen are combined. The end result of the chemical reaction is entirely distinct from the initial component.
The heat from the heat causes some of the cellulose material that makes up the wood to break down when the wood reaches about 300 degrees Fahrenheit (150 degrees Celsius).
The molecules of the complex disintegrate at a temperature of roughly 500 degrees F (260 degrees C) for wood, at which point the atoms recombine with oxygen to generate water, carbon dioxide, and other products. They burn, in other terms.

What has the smallest effect on the rate of photosynthesis.
Answer:
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
The smallest effect on the rate of photosynthesis is typically the availability of carbon dioxide (CO2).
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen.
Other factors that can influence the rate of photosynthesis to a greater extent than carbon dioxide include:
Light intensity: The rate of photosynthesis increases with higher light intensity, up to a certain point. Beyond that point, called the saturation point, increasing light intensity does not further increase the rate of photosynthesis.
Temperature: Photosynthesis is a temperature-dependent process. Within an optimal temperature range, the rate of photosynthesis increases with higher temperatures.
Water is essential for photosynthesis as it provides the medium for chemical reactions to occur. Inadequate water availability can lead to a decrease in photosynthesis.
Therefore, while all the factors mentioned (light intensity, temperature, water availability) can significantly impact the rate of photosynthesis, the availability of carbon dioxide generally has the smallest effect.

A cart with an unknown mass is at rest on one side of a track. A student must find the mass of the cart by using newton’s second law. The student attaches a force probe to the cart and pulls it while keeping the force constant. A motion detector rests on the opposite end of the track to record the acceleration of the cart as it is pulled. The student uses the measured force and acceleration values and determines that the cart’s mass is 0. 4kg. When placed on a balance, the cart’s mass is found to be 0. 5kg. Which of the following could explain the difference in mass?.

Which presidential campaign slogan best demonstrates an unwarranted extrapolation?.
You wish to earn a return of 13% on each of two stocks, x and y. Stock x is expected to pay a dividend of $3 in the upcoming year while stock y is expected to pay a dividend of $4 in the upcoming year. The expected growth rate of dividends for both stocks is 7%. The intrinsic value of stock x.
Based on the information given, the intrinsic value of stock x will be less than the intrinsic value of stock Y.
Based on the information given above, the intrinsic value of Stock X will be calculated thus:
D1 = Dividend in next year = $3
g = growth rate = 7%
r = = 13%
Therefore, intrinsic value of Stock X will be:
= D1 / (r-g)
= 3 / (13% - 7%)
= 3/6%
= 3 / 0.06
= $50
Therefore, the intrinsic value of stock X is $50.
Intrinsic value of Stock Y will be calculated thus:
D1 = $4
g = 7%
r = 13%
Intrinsic value of Stock Y will be:
= D1 / (r-g)
= 4 / (13% - 7%)
= 4/6%
= 4 / 0.06
= 66.67
Intrinsic value of Stock Y is $66.67
Therefore, the intrinsic value of Stock X will be less than the intrinsic value of Stock Y.
