(Type your answer using the appropriate number of significant digits. Type you
Answers
The mass of 21,000 molecules of oxygen in scientific notation is expressed as 1.1151 x [tex]10^{-28}[/tex] grams in the proper significant digits.
What are Significant Digits?The number that is provided as digits is tried and established using significant figures. A meaningful representation of numbers is carried by these digits.
The crucial or important digits that can accurately represent the exact meaning of a certain number are known as the significant figures of that number.
Frequently, significant digits are employed in place of figures. By counting out each of the values beginning with the first non-zero digit on the left, we can use it to determine the number of significant digits.
The molecular mass of Oxygen is seen as 32 grams.
So, 6.023 x [tex]10^{23}[/tex] molecules of oxygen have mass as 32 grams
So, one molecule of oxygen has mass = [tex]\frac{32}{6.023 * 10^{23}}[/tex] grams
= 5.31 x [tex]10^{-23}\\[/tex] grams
So, 21,000 molecules will have mass = 21,000 x 5.31 x [tex]10^{-23}\\[/tex] grams
= 111510 x [tex]10^{-23}\\[/tex] grams
= 1.1151 x [tex]10^{-28}[/tex] grams
Thus 21000 molecules of oxygen have a mass of 1.1151 x [tex]10^{-28}[/tex] grams.

Skill BuildeWatch the video and then solve the problem given below.Click here to watch the videoMargaret drove to a business appointment at 40 mph. Her average speed on the return trip was 30 mph. The return trip took 1/3 hour longer because of heavy traffic. How far did she travel to theappointment?She traveled milesEnter your answer in the answer box and then click Check Answer.All parts showing
Answers
Let's call the distance to the appointment 'd', and the time of the first travel (going to the appointment) 't'.
Now, we need to use the formula for the distance:
[tex]\text{distance}=\text{average speed }\cdot\text{ time}[/tex]For the first part of the trip, we have the distance 'd', the average speed is 40 mph and the time is 't':
[tex]d=40\cdot t[/tex]Then, for the second part of the trip (return trip), the distance is also 'd', the average speed is 30 mph, and the time is 't + 1/3', because she took 1/3 hour longer than the first trip.
So we have that:
[tex]d=30\cdot(t+\frac{1}{3})=30t+10[/tex]Now, we just need to equate both 'd':
[tex]\begin{gathered} 40t=30t+10 \\ 10t=10 \\ t=1 \end{gathered}[/tex]So the time 't' is 1 hour. Now we can use that to find the distance 'd':
[tex]d=40t=40\cdot1=40[/tex]So the distance to the appointment is 40 miles.
If you save $750 monthly for the next 30 years, how much would your retirement fund be worth, assuming that you can earn 3%, compounded monthly?
Answers
The amount compounded monthly is 1092.63.
The expression for calculating the amount compounded monthly is given by the formula

where P is the principal amount, r is the interest rate in decimal form, and t is the time.
The Data and information which are provided in the question are,
The principle amount, P = 750
The rate of interest, R = 3%, so 3÷100 = 0.03
The period, t = 30.
By substituting the data in the equation, the equation becomes
CI = 750×[tex](\frac{1+0.03}{12}) ^{360}[/tex] - 750.

The combination that gives the most profit exists 12nVIP rings and 12 SST rings (900 day).
What is meant by linear programming?When a linear function is exposed to various constraints, it is maximized or reduced using the mathematical modeling technique known as linear programming. In commercial planning, industrial engineering, and—to a lesser extent—the social and physical sciences, this method has proven helpful for directing quantitative decisions.
This is a linear programming problem.
The objective function is profit R, which has to be maximized.
R = 40 V + 35 S
being V: number of VIP rings produced, and S: number of SST rings produced.
The restrictions are
Amount of rings (less or equal than 24 a day):
V + S ≤ 24
Amount of man-hours (up to 60 man-hours per day):
3 V + 2 S ≤ 60
The number of rings of each type is a positive integer:
V, S ≥ 0
This restrictions can be graphed and then limit the feasible region. The graph is attached.
In which 2 of the restrictions are saturated. In one of these three points lies the combination of V and S that maximizes profit.
The points and the values for the profit function in that point are:
Point 1: V = 0 and S = 24
R = 40 V + 35 S = 40 × 0+35 × 24 = 0 + 840
R = 840
Point 2: V = 12 and S = 12
R = 40 V + 35 S = 40 × 12 + 35 × 12 = 480 + 420
R = 900
Point 3: V = 20 and S = 0
R = 40 V + 35 S = 40 × 20+35 × 0 = 800 + 0
R = 800
The combination that gives the most profit is 12nVIP rings and 12 SST rings (900 day).
The complete question is:
The Acme Class Ring Company designs and sells two types of rings: the VIP and the SST. They can produce up to 24 rings each day using up to 60 total man-hours of labor. It takes 3 man-hours to make one VIP ring, versus 2 man-hours to make one SST ring. How many of each type of ring should be made daily to maximize the company's profit, if the profit on a VIP ring is $40 and on an SST ring is $35?

Like the name suggests, one-to-one functions have each input variable having exactly one unique output. That is, multiple inputs never give the same output.
Also noting that the data in the function are written as

Answers
Answer- 62%
Step-by-step explanation
5+5+8+8= 26 There are 8 peanut butter cookies,so 8/26 is the chance we will get a peanut butter cookie. In percentage form that is 0.307692308 or 30% chance that a peanut butter cookie will be selected. This also means that since there are 8 oatmeal there is a 30% percent chance for those as well.5/26 is 0.192307692, which is almost 20 percent. 30 +30 +20+20 is 100 percent. Now that we know there is a 30 percent for both peanut butter and oatmeal, we would have to have the percent of 8+8/26. 16/26 is 0.615384615. This means that the chance of picking a peanut butter then oatmeal cookie, back-to-back would be around 62%

(10) Use the following freauency bar graph to answer the following questions.Chart of MTH 150 GradescountGradesa) How many students received a C for the course?b) How many students passed the course (with a C or higher)?c) How many students received no credit for the course (i.e. got an F)?d) How many total students took the course?e) Which letter grade represents the mode?
Answers
From the frequency bar graph, we can read the following information.
15 students got an A
6 students got a B
5 students got a C
10 students got a D
14 students got an F
a) As described above, 5 students got a C
b) Adding up the frequencies of the students who got C or higher:
5 + 6 + 15 = 26
26 students passed the course
c) Assuming the students who did not pass got any credits, then we add up the students with D and F: 10 + 14 = 24
24 students received no credit for the course
d) Total students in the course: 15 + 6 + 5 + 10 + 14 = 50
e) The mode is the letter grade that got the highest frequency:
Mode = A
A got 15
What is the degree of the power function represented in the table f(x)
-3, -2, -1, 0, 1, 2, 3
Answers
The degree of the power function represented in the table f(x) is 2.
How to illustrate the information?In order to find the degree of the power function represented in the given table, you must find the difference of the y-values.
The second difference is illustrated as:
2 - 6 = -4.
-2 - 2 = -4
-6 - (-2) = -4
This illustrates that the second differences are constant.

Answers
The best method for solving a system of linear equations is the substitution method.
What is a system of equations?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
We have been given the system of the equations as;
y = -2x + 2
y = 4x + -4
Thus, y = -2 x + 2 ........ equation number 1
y = 4 x - 4.............. equation number 2
Then substitute equation number 2 in equation number 1
4 x - 4 = -2 x + 2
4 x + 2 x = 2 +4
6 x = 6
so, x = 1
Now substitute x= 1 in equation number 2;
Therefore y =( 4 × 1) - 4
y = 4 - 4 = 0
For x = 1 and y = 0
Hence, the best method for solving a system of linear equations is the substitution method.
