Answer:

The answer to your question is 224 π in³

Step-by-step explanation:

Data

Cylinder                      Cone

height = 12 in              height = 6 in

radius = 4 in                radius = 4 in

Volume = x                 Volume = y

Process

1.- Calculate the volume of the Cylinder

V = πr²h

V =  π (4)²(12)

V =  π(16)(12)

V = 192 π

2.- Calculate the volume of the Cone

V = 1/3  πr²h

V = 1/3  π(4)²(6)

V = 1/3  π(16)(6)

V = 96/3  π

V = 32 π

3.- Calculate the volume of the head

Volume = 192 π + 32 π

Volume = 224 π in³

Jake cannot achieve an average above 89 with the final exam alone.

The final exam counts twice as much as the midterm, so the weights are 2 for the final and 1 for the midterm. The average score A can be calculated using the formula:

[tex]\[ A = \frac{\text{weight of midterm} \times \text{midterm score} + \text{weight of final} \times \text{final score}}{\text{total weight}} \][/tex]

Given that Jake's midterm score is 67 and the weights are 1 for the midterm and 2 for the final, the total weight is  1 + 2 = 3 . We want Jake's average A to be between 81 and 92.

For the lower bound of the average (81), we have:

[tex]\[ 81 = \frac{1 \times 67 + 2 \times f}{3} \][/tex]

Solving for  f :

[tex]\[ 81 \times 3 = 67 + 2f \] \[ 243 = 67 + 2f \] \[ 2f = 243 - 67 \] \[ 2f = 176 \] \[ f = \frac{176}{2} \] \[ f = 88 \][/tex]

So, the minimum score Jake needs on the final exam to achieve an average of at least 81 is 88.

For the upper bound of the average (92), we have:

[tex]\[ 92 = \frac{1 \times 67 + 2 \times f}{3} \][/tex]

Solving for  f:

[tex]\[ 92 \times 3 = 67 + 2f \] \[ 276 = 67 + 2f \] \[ 2f = 276 - 67 \] \[ 2f = 209 \] \[ f = \frac{209}{2} \] \[ f = 104.5 \][/tex]

However, since the maximum score for the final exam is 100, the highest possible average Jake can achieve is 100 (since [tex]\( 67 + 2 \times 100 = 267 \)[/tex], and [tex]\( \frac{267}{3} = 89 \))[/tex].

In conclusion, Jake needs to score at least 88 on the final exam to achieve an average of at least 81, but he cannot achieve an average above 89 with the final exam alone. Thus, the range of scores on the final exam for Jake to get an average between 81 and 92 is from 88 to 100. However, the upper bound of Jake's average is actually 89, not 92, due to the maximum score constraint on the final exam.

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.

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.

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.

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.

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.

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.

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.

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

Step-by-step explanation:

EF is the midline of the trapezoid so its length is the average of the two base lengths:

  (AD +BC)/2 = EF

  AD +BC = 2·EF . . . . multiply by 2

  8 +2x -4 = 2(x+2) . . . substitute the expressions for the segment lengths

  2x +4 = 2x +4 . . . . . . true for any value of x

We only require that segment BC is non-negative in length, so ...

  BC ≥ 0

Given

The perimeter of the fence is 68 feet

The area of the rectangular yard is 240 square feet

Let the length be x feet and breadth is y feet

According to the problem,

2(length+breadth)=68

⇒2(x+y)=68

⇒[tex](x+y)=\frac{68}{2}[/tex]

[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]

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
