Answer:
Explanation:
If y is the total cost to mail a letter, that is what your equation should be set equal to.
y = _________
Then, just to be able to send the letter, you have to pay .46 before you even weigh it.
y = 0.46 + _____
Finally, you can weigh your letter to determine how much more you'd have to pay (it wouldn't be fair if a 1 ounce letter and a 5 pound letter costed the same!). The problem gives you the variable for ounces, so you would do
price x ounces.
y = 0.46 + 0.20x
(I'm not sure what the name of the equation is, but it is in y = mx + b form. I believe it is "slope intercept"? That should be somewhere in your notes. Hope this helps :) )

The chemical equation below shows the combustion of methane (ch4). Ch4 + 2o2 right arrow. Co2 + 2h2o the molar mass of oxygen gas (o2) is 32. 00 g/mol. The molar mass of carbon dioxide (co2) is 44. 01 g/mol. What mass of co2, in grams, will form when 8. 94 g o2 completely react?.
Taking into account the reaction stoichiometry, 6.15 grams of CO₂ are formed when 8.94 grams of O₂ reacts completely.
In first place, the balanced reaction is:
CH₄ + 2 O₂ → CO₂ + 2 H₂O
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
CH₄: 1 mole O₂: 2 moles CO₂: 1 mole H₂O: 2 molesThe molar mass of the compounds is:
CH₄: 16.04 g/mole O₂: 32 g/moleCO₂: 44.01 g/moleH₂O: 18 g/mole
Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
CH₄: 1 mole× 16.04 g/mole= 16.04 gramsO₂: 2 moles× 32 g/mole= 64 gramsCO₂: 1 mole× 44.01 g/mole= 44.01 gramsH₂O: 2 moles× 18 g/mole= 36 grams
Then the following rule of three can be applied: if by reaction stoichiometry 64 grams of O₂ form 44.01 grams of CO₂, 8.94 grams of O₂ form how much mass of CO₂?
[tex]mass of CO_{2} =\frac{8.94 grams of O_{2} x44.01 grams of CO_{2} }{64 grams of O_{2}}[/tex]
mass of CO₂= 6.15 grams
Finally, 6.15 grams of CO₂ are formed when 8.94 grams of O₂ reacts completely.

Maximize the objective function p = 5x + 3y for the given constraints. X ≥ 0 y ≥ 0 3x + 6y ≤ 48 2x + 8y ≤ 56.
The maximized value of the objective function is 38
The objective function is given as:
Max P = 5x + 3y
The constraints are given as:
3x + 6y ≤ 48 2x + 8y ≤ 56x ≥ 0 y ≥ 0To do this, we make use of the graphical method.
See attachment for the graph of the constraints.
From the graph, we have the following feasible point
[tex](x,y) = (4,6)[/tex]
Substitute 4 for x and 6 for y in the objective function.
[tex]Max\ P = 5x + 3y[/tex]
So, we have:
[tex]P = 5 \times 4 + 3 \times 6[/tex]
[tex]P = 20 + 18[/tex]
[tex]P = 38[/tex]
Hence, the maximized value of the objective function is 38

https://brainly.com/question/16826001
Answer:
Explanation:
If an objective function has a maximum value, it will occur at one of the vertices of the feasible region (i.e., the solution region for the system of inequalities). The feasible region's vertices occur at (0, 0), (0, 7), (4, 6), and (16, 0).
Use the x- and y-value from each vertex to evaluate the objective function P = 5x + 3y.
(x, y) 5x + 3y P
(0, 0) 5(0) + 3(0) 0
(0, 7) 5(0) + 3(7) 21
(4, 6) 5(4) + 3(6) 38
(16, 0) 5(16) + 3(0) 80
Therefore, the maximum of the objective function is 80.

The amount and the concentration of a salt solution.
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

You know that % means /100, so 35% = 35/100 = 0.35.
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

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

It takes 87 j of work to stretch an ideal spring, initially 1. 4 m from equilibrium, to a position 2. 9 m from equilibrium. What is the value of the spring constant (force constant) of this spring?.
The spring undergoes a change in potential energy of
1/2 k (2.9 m)² - 1/2 k (1.4 m)² = 87 J
Solve for k :
k ((2.9 m)² - (1.4 m)²) = 174 J
k = (174 J) / ((2.9 m)² - (1.4 m)²)
k ≈ 27 N/m
What change in a population would you expect to see if a selection pressure was against the trait of a dominant allele in that population?.
Answer:
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

The rock travels a horizontal distance x after time t of
x = (12.2 m/s) cos(63°) t
If it hits the ground 25 m away from where it was thrown, then for some time t we have
25 m = (12.2 m/s) cos(63°) t
Solve for t :
t = (25 m) / ((12.2 m/s) cos(63°))
