Answer:
28 g
3.4 g
Explanation:
These problems only make sense if the percentage is by weight. To find the amount of salt, multiply the amount of solution by the percentage that is salt:
a) (80 g)(35%) = 28 g . . . . weight of salt
__
b) (20 g)(17%) = 3.4 g . . . . weight of salt
_____
Comment on percent
You know that % means /100, so 35% = 35/100 = 0.35.

What are the equations of the asymptotes of the hyperbola? (y+4)236−(x−6)249=1 enter your answer in point-slope form by filling in the boxes. Enter the slope as a simplified fraction.
The point slope form of the asymptote of the hyperbola is; y - 4 = ±(6/7)(x - 6)
We are given the equation of the hyperbola as;[(y + 4)²/36] - [(x - 6)²/49] = 1
We can rewrite this equation as;[(y + 1)²/6²] - [(x - 6)²/7²] = 1
The general equation form of hyperbola is;[(y - k)²/a²] - [(x - h)²/b²] = 1
Comparing this general form to our given equation we can see that;k = -4
h = 6
a = 6
b = 7
Now the equation of the asymptote of a hyperbola follows the general formula;y = ±[a(x - h)/b] + k
Plugging in the relevant values gives us;y = ±(6/7)(x - 6) - 4
>> y - 4 = ±(6/7)(x - 6)

A group of campers walked at a speed of 4. 5 mph from their campsite to a rest area. Their return trip to the campsite took 15 minutes longer because their speed was only 4 mph. What is the distance between the campsite and the rest area?.
The distance between the campsite and the rest area is 9 miles.
The given parameters:
Initial speed of the campers, u = 4.5 mphFinal speed of the campers, v = 4 mphLet the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.

A food worker takes three hours to reheat a pot of soup for a buffet to 165°f (74°c).
An action the food worker must take next is to throw the soup out.
Food preservation is an art that typically involves the process of preventing food spoilage by mitigating or reducing the activities (growth) of microbial organisms and other external factors while maintaining the nutritional value, flavor and texture of a food.
Some of the common factors that result in food spoilage include the following:
TemperatureOxidationMoisture contentPathogens (microorganisms) such as yeast, molds, bacteria, etc.A soup is an example of a time/temperature control for safety (TCS) foods because they are more susceptible to the growth of pathogens (microorganisms) such as yeast, molds, bacteria, etc.
For TCS foods, it is important that they are cooled from 135 Fahrenheit (°F) to 70 Fahrenheit (°F) within two (2) hours, else, it must be thrown out. Since this food worker took three (3) hours to reheat the pot of soup to 165°F (74°C), he or she must throw the soup out because it has exceeded the minimum time required for TCS foods.

Which main problem is being solved by the hubble space telescope?.
The Hubble Space Telescope's primary problem is option D, i.e., trying to identify the brightest stars in the galaxy.
What is a Hubble Space Telescope?The Hubble Space Telescope is a space telescope that was initiated into low Earth orbit in 1990 and is still active today.
It was not the first space telescope, but it is one of the biggest and most versatile, known for its importance as a research tool as well as a public relations boon for astronomy.
Hubble was intended to be a multi-purpose observatory capable of exploring the universe in visible, ultraviolet, and infrared wavelengths.
To date, the telescope has studied over 40,000 cosmic objects, providing views that astronomers could not obtain from the ground.
The primary challenge for the Hubble Space Telescope is identifying the brightest stars in the galaxy.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.
Answer:
The first law describes how thermal energy is conserved but not the direction it moves.
Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).
As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.
Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

A spring with a spring constant of 150 n/m has an equilibrium length of 8. 0 cm. What is the change in spring potential energy when the spring is stretched from a length of 11. 0 cm to 14. 0 cm?.
When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores
1/2 (150 N/m) (0.030 m)² = 0.0675 J
of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores
1/2 (150 N/m) (0.060 m)² = 0.27 J
Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J
If a recessive allele helps an organism reproduce but a dominant allele hinders reproduction, which will become more prominent over time?.
It is expected the recessive allele becomes more prominent over time.
In general, nature favors traits that help organisms survive and reproduce. This occurs through a process known as natural selection that helps the population to evolve to have favorable traits.
This evolution occurs externally as organisms change their physical traits or phenotype, but also at a genetic level.
This implies that even if a trait is genetically dominant if the trait does not favor survival and reproduction, this trait will slowly disappear or reduce over generations.
Based on this, the recessive allele will become more prominent because this trait favors reproduction, while the dominant allele will become less prominent.
