Answer: 1
Step-by-step explanation:
Use the following information to complete parts I, II, and III. 1 hour=3600 seconds
1 year = 31556952 secondsI. Use scientific notation to estimate the number of hours in one year. II. Use scientific notation to calculate the exact number of hours in one year. III. In two or more complete sentences, compare your answers to parts I and II. In your comparison, discuss similarities and differences.
Answer:
I) 8.760 * 10 ³ hours
II) 8.76582 * 10 ³ hours
Step-by-step explanation:
1) No. of hours in one year:
24 hours* 365 days= 8760 hours
Scientific Notation= 8.760 * 10 ³ hours
2) 1 year = 31556952 seconds
1 hour=3600
1 year = 31556952 seconds/3600 = 8765. 82 hours
Scientific Notation= 8.76582 * 10 ³ hours
3) The exact numbers of hours using 365 days is 8760 which is written as 8.760* 10 ³ in scientific notation. But using the given data we get =8.76582 * 10 ³ hours
Comparing these answers the first one has only 3 significant figures
But the second answer has six significant figures if we round these we get 8.8 * 10 ³ hours which has two significant numbers
Aslo rounding the first gives 8.8 * 10 ³ hours which has two significant numbers and is the same as the other answer rounded
Dianna and Becky were playing on the same soccer team and took turns being goalie. They stoped 9 out of 10 shots made against them. If the other team scored 3 points, how many balls did Dianna and Becky stop from going into the net?
Answer:
27 balls
Step-by-step explanation:
If Dianna and Becky stopped 9 out of 10 shots made against them.
It means they allowed in 1 out of 10 shots made against them.
This is best solved using ratios
Proportion of Shots Stopped : Proportion of Shots allowed=9:1
If the other team scores 3 points, it means the number of shots allowed =3
Let x be the number of shots stopped
Number of Shots Stopped : Number of Shots allowed=x:3
Therefore:
9:1=x:3
[tex]\frac{9}{1}=\frac{x}{3}[/tex]
Cross multiplying
x=9 X 3 =27
Dianna and Becky stopped 27 balls from going into the net,

The answer to your question is Yes, the point P lies on the circle
Step-by-step explanation:
Data
P (2[tex]\sqrt{3}[/tex], 2)
Center (0, 0)
Q (0, -4)
Process
1.- Find the radius of the circle
dCQ = [tex]\sqrt{(0-0)^{2}+ (-4 + 0)^{2}}[/tex]
dCQ = [tex]\sqrt{0^{2} + (-4)^{2}}[/tex]
dCQ = [tex]\sqrt{16}[/tex]
dCQ = 4
2.- Find the equation of the circle
(x - 0)² + (y - 0)² = 4²
-Simplification
x² + y² = 16
3.- Substitute P in the equation of the circle
(2[tex]\sqrt{3}[/tex])² + (2)² = 16
4(3) + 4 = 16
12 + 4 = 16
16 = 16

The point (2[tex]\sqrt{3}[/tex], 2) lies on the circle because when we evaluate the equation of the circle with this point, we get the length of the radius.
In a round robin tennis tournament, each player plays every other player exactly once. Use induction to show that if there are n players there will be n(n − 1)/2 games.
Answer:
Step-by-step explanation:
given that in a round robin tennis tournament, each player plays every other player exactly once.
Suppose there are two players i.e. n=2, we have only one match satisfies
[tex]\frac{2(2-1)}{2} =1[/tex]
Hence P(2) is true
Assume P(k) is true. For k players no of matches played
= [tex]\frac{k(k-1)}{2}[/tex]
To prove true for n = k+1
If to k players one new player is introduced, then the new player should play all the k players to have the condition satisfied
i.e. no of matches = no for k players + k
= [tex]\frac{k(k-1)}{2} +k\\= \frac{k^2-k+2k}{2} \\= \frac{(k+1)k}{2}[/tex]
So if true for n =k, then true for n =k+1
Already true for n =2
By induction true for all natural numbers starting from 2.

December 26 *Received all the goods that Waren authorized Eastern Wisonsin University to return on EWU's return request No. R8034 for credit against their account balance. **Process and record the sales return now. December 26 * Receive check No. 49326 for $10,000 for Eastern Wisconsin University in partial payment of the remaining amount (after sales return) on charge invoice No. 729, and deposited the check. **Do not finalize a deposit slip until you determine whether there are no other cash receipts on the same day. After entering the partial payment for invoice #729 with check 49326, where else am I suppose to post to? With the check from EWU, would you post this in the Cash Disburstments Journal?
Answer:
No. When goods are returned, it is termed as sales return and when the check has been collected as partial payment, it is recorded in cash receipt journal and not in cash Disbursements Journal.
Step-by-step explanation:
When goods are returned, it is termed as sales return and when the check has been collected as partial payment, it is recorded in cash receipt journal and not in cash Disbursements Journal.
In cash disbursement journal, transactions are recorded as related to payments made while in cash Receipt Journal ,transactions are recorded when the money has been received.
The question refers to a business transaction scenario wherein goods authorized by Waren for return by Eastern Wisconsin University (EWU) have been received. This event will result in a credit against EWU's account balance with Waren, marked by return request No. R8034.
Explanation:The scenario mentioned refers to a business transaction between two entities, Waren and Eastern Wisconsin University (EWU). In this situation, EWU is returning goods back to Waren, which have been authorized by the latter. Following successfully receiving the goods, Waren would credit the account balance of EWU, essentially setting off the monetary value of the returned goods against any debt that EWU might owe Waren. This is a common practice in various business transactions and is known as Returns against credit.
The return request No. R8034 specifically identifies this transaction, enabling the parties involved to keep track of their exchanges and to effectively manage their financials.

[tex]\Rightarrow x+y=34[/tex] .......(1)
The area of the rectangular is
length×breadth=240
⇒x×y=240
[tex]\Rightarrow x=\frac{240}{y}[/tex]
Putting the value x in the equation
[tex]\frac{240}{y}+y=34[/tex]
[tex]\Rightarrow \frac{240+y^2}{y}=34[/tex]
[tex]\Rightarrow 240+y^2=34y[/tex]
⇒y²-34y+240=0
⇒y²-24y-10y+240=0
⇒y(y-24)-10(y-24)=0
⇒(y-24)(y-10)=0
⇒y=24,10
When, y=24
[tex]x=\frac{240}{24}=10[/tex]
When y=10

f(x)=sqrt(x)
g(x)=5x^2+4
h(3)=[]
h'(3)=[]/[]
Answer:
h(3) = 7
h'(3) = 15/7
Step-by-step explanation:
h(3) = f(g(3)) = f(5(3²)+4)
h(3) = f(49)
h(3) = 7
h(x) = (5x² + 4)^½

The frequency of red light is about 4.3 x 10^14 Hz. The frequency of violet light is about 7.5 x 10^14 Hz. What is the approximate difference in frequency between red light and violet light?
Answer:
The difference in frequency between red light and violet light is 3.2×10¹⁴Hz.
Step-by-step explanation:
Frequency :During any time interval the number of waves which pass through a point in space is known as frequency of that ray.
The unit of frequency is Hz.
There are 7 colors in white ray. The highest frequency color is violet and lowest frequency color is red.
Given that the frequency of red is 4.3 ×10¹⁴Hz.
The frequency of violet ray is 7.5×10¹⁴Hz.
The difference in frequency between red light and violet light is
=(7.5×10¹⁴-4.3×10¹⁴)Hz
=(7.5-4.3)×10¹⁴Hz.
=3.2×10¹⁴Hz.
The difference in frequency between red light and violet light is found by subtracting the frequency of the red light from that of the violet light. The resulting difference is approximately 3.2 x 10^14 Hz.
Explanation:The frequency of light is a measurement of how many waves pass a point in a given period of time. To find the difference in frequency between the red light and the violet light, we need to subtract the frequency of the red light from the frequency of the violet light.
The frequency of violet light is 7.5 x 1014 Hz, while the frequency of red light is 4.3 x 1014 Hz. To calculate the difference, we subtract these two frequencies as follows:
7.5 x 1014 Hz - 4.3 x 1014 Hz = 3.2 x 1014 Hz
Therefore, the approximate difference in frequency between red light and violet light is 3.2 x 1014 Hz.

Consider the following. (a) Explain why −0.41 cannot be the probability of some event. A probability must be between zero and one. A probability must be greater than one. A probability must be an integer.
Answer:
A probability must be between zero and one
Step-by-step explanation:
We are to explain why −0.41 cannot be the probability of some event.
Probability is the chance of occurring a particular event out of total possible events.
If total possible events are n, and number of favourable outcomes for any event A is x then probability is x/n.
Here note that both x and n cannot be negative.
also x cannot exceed n.
Probability can never exceed 1 and also can never be an integer except 0 or 1 as special cases.
So the probability can never be negative and cannot exceed 1.
So correct answer is
A probability must be between zero and one
Suppose that three compact discs are removed from their cases, and that after they have been played, they are put back into the three empty cases in a random manner. Determine the probability that at least one of the CD’s will be put back into the proper cases.
Answer:
The probability that at least one of the CD'S will be put back into the proper cases is 2/3
Step-by-step explanation:
The total amount of possibilities of putting back the CD's is equal to the total amount of ways of ordering a set of 3 elements, in other words, 3! = 6. In 4 of those 6 ways, at least one of the CD's is put back properly:
- All CD's are put back into the proper cases
- First disc is put back into its proper cases, Second disc is put back in third's position, and third disc is put back in second's position.
- Second Disc is put back correctly, and first and third not
- Thir disc is put back correctly and first and second got 'swapped'.
Thus, the probability that at least one of the CD'S will be put back into the proper cases is 4/6 = 2/3.
A cellular phone company charges a $25 monthly fee and an additional $0.10 per minute. If m represents the number of minutes of phone usage, which equation can be used to determine the total monthly cost, c?
Answer:
c= 0.10m+ 25
Step-by-step explanation:
using the format y=mx+b
25 is your flat cost that they charge every month, and 0.10 is what they charge per minute.
m is the number of minutes so that is the unknown variable.
c is your total cost.
you take the flat cost per month (25 dollars) and add it to however many minutes multiplied by 0.10 (.10m)
The equation for determining the total phone bill given a monthly fee of $25 and a rate of $0.10 per minute is, c = 25 + 0.10m. Here, c represents the total monthly cost and m represents the number of minutes of phone usage.
Explanation:The subject of the question is linear algebra, and it requires forming an equation for a given scenario. In this case, the monthly cost of the cellular phone service is a function of the number of minutes of phone usage. The fixed monthly fee is $25, and there is an additional charge of $0.10 per minute.
So if m represents the number of minutes of phone usage, and c represents the total monthly cost, then the equation that can be used is: c = 25 + 0.10m
This is because for each minute used, an extra $0.10 is added to the total cost. If no minutes are used, the total cost is just the fixed $25. If 50 minutes are used, for example, the total cost is $25 + (0.10 * 50) = $30.

1. Chapter ma2pe08r, Section .72, Problem 012 (ID: 012.07.2 - MC - MANK08) David tunes pianos in his spare time for extra income. Buyers of his service are willing to pay $135 per tuning. One particular week, David is willing to tune the first piano for $115, the second piano for $125, the third piano for $140, and the fourth piano for $175. Assume David is rational in deciding how many pianos to tune. His producer surplus is a. $-15. b. $20. c. $30. d. $75.
Answer:
Option C. $30
Step-by-step explanation:
As per question buyers are willing to pay $135 per tuning. If David demands more than this amount producer will not choose David to tune.
As we can see on first week David is willing to tune the first piano for $115,
So surplus for producer will be
135 - 115 = $20
Surplus for second week for producer will be
135 - 125 = $10
Since David is willing to tune the third and fourth piano for $140 and $175 then the producer will not choose David for tuning.
Therefore, total surplus for the producer will be $20 + $10 = $30
Option C. $30 is the correct option.
5 4 start fraction, 4, divided by, 5, end fraction of their popcorn with butter. The remaining 35.235.235, point, 2 ounces was made without butter. How many pounds of popcorn did Movietown Theater make on Thursday?
Answer:
Movietown Theater made a total of 10.2 pounds of butter on Thursday
Step-by-step explanation:
Movietown Theater made [tex]\frac{4}{5}[/tex] fraction of their popcorn with butter and 32.5 ounces without butter.
Fraction made without butter=[tex]1-\frac{4}{5}=\frac{1}{5}[/tex]
It means [tex]\frac{1}{5}[/tex] of total popcorn made(t) was without butter.
[tex]\frac{1}{5}Xt=32.5[/tex]
t=32.5X5=162.5
They made 162.5 ounces of butter in total
Next, we determine the weight in pounds
16 ounces = 1 pound
162.5 ounces = 162.5/16 pounds
=10.2 pounds
