Elleanna is planning to join a DVD club and is investigating the options for membership. Option 1 is $20 membership fee $1.25 rental change for each DVD rented. Option 2 has no rental fee and changes $2.50 for each DVD rented. How many DVDs would Elleanna have to rent in order for the total cost of Option 1 to be equal to option 2?

Answers

option 1 : 20 + 1.25d
option 2 : 2.50d

when will they be equal......so set them equal to each other
20 + 1.25d = 2.50d
20 = 2.50d - 1.25d
20 = 1.25d
20 / 1.25 = d
16 = d.....so they will be equal at 16 dvd rentals

Surface area of a right cone.
Solve for P S=2b+ph

Answers

s = 2b + ph

Lets subtract both sides by 2b

s - 2b = ph

Now, divide both sides by h

(s-2b)/h = p

Hope this helps!

Answer:

P=S-2b/h

Step-by-step explanation:

To solve this equation the first thing we do is subtract 2B from both sides of the equation. S-2b=ph+2b-2b which would give us S-2B=PH. next, we divide H from both sides of the equation which would give us the answer: S-2B/h=p

A retired woman has $60,000 to invest but needs to make $6,000 a year from the interest to meet certain living expenses. One bond investment pays 15% annual interest. The rest of it she wants to put in a CD that pays 7%. If we let x be the amount the woman invests in the 15% bond, how much in dollars will she be able to invest in her CD?

Answers

Let x be the amount the woman invests in the 15% bond, then the amount she invested in her CD is given by $60,000 - x.

The interest she receives from the 15% bond is given by 0.15x while the interest she receives from the 7% CD is given by 0.07(60,000 - x) = 4,200 - 0.07x

Giving that her total annual interest is $6,000, then

[tex]0.15x+4,200-0.07x=6,000 \\ \\ \Rightarrow0.08x=6,000-4,800=1,200 \\ \\ \Rightarrow x= \frac{1,200}{0.08} =$15,000[/tex]

Therefore, the amount of dollars she will be able to invest in her CD is $60,000 - $15,000 = $45,000

what is twenty less than twelve percent of a number minus the sum of twice the number and negative fifteen

Answers

(0.12*x - 20) - (2x + -15)

So basically here, you can write out the equation, what is twenty less

-20

Than twelve percent of a number (we have to create a variable here)

0.12x - 20

Minus

(0.12x - 20) -

The sum of twice the number

(0.12x - 20) - 2x

and negative fifteen

(0.12x - 20) - (2x + -15)

So to solve this, you want to open up both parenthesis, the first one is easy, and the second one, reversing all operations inside.

0.12x - 20 - 2x - -15

or

0.12x - 20 - 2x + 15

(because two minuses equals one plus)

Now you can reorder all of the components, having them keep the sign before them

(+) 0.12x - 2x + 15 - 20

Or

-1.88x + -5

And so there we go, that's the most we can do.

(Or something I probably made a mistake at some point)

Hi there! I'll try to help you throughout this. :)

First, write your equation in number form, obviously.

[(0.12 * n) - (2n + -15)] - 20

Second, multiply -1 to the second half of the parentheses.

[(0.12 * n) + (-2n + 15)] - 20

Now multiply, group, and simplify!

(0.12n + -2n + 15) - 20

-1.73n + 15 - 20

-1.73n - 5

There you are. :)

I may be wrong, but I do believe the answer is -1.73n - 5.

Why -4 x (-4) = 16 not -16? Simple...

Answers

The reason why it is a positive 16 and not a negative 16, is because when you multiply a negative number with another negative number you will always get a positive number. But, if you multiple a negative number with a positive number, you will get a negative. So, in order for you to get a -16, the equation would have to be -4*4=-16.

Let the temperature be initially be t.

Let [tex]\displaystyle{ d_n[/tex] be the temperature after day 1 of the period where the teperature decreases.

For example,

[tex]\displaystyle{ d_1[/tex] is the temperature after the first day

[tex]\displaystyle{ d_2[/tex] is the temperature after the second day

and so on...

The temperatures during these 10 days are:

The change of the temperature each day, is given by the difference of the temperature in 2 consecutive days, for example day 4 and day 5:

[tex]d_5-d_4=(t-5\cdot 5)-(t-4\cdot5)=t-25-t+20=-5[/tex]

Music may help people relax. John got two groups of people together. He took everybody's pulse of blood pressure. The one group to listen to soothing music while other group sat in silence. After the song was over, he measured everyone's pulse and blood pressure.

What is the independent variable?
What is the dependent variable?
What are the constants or control variables?

Answers

Independent: Music or silence

Dependent: Pulse and blood pressure

Constants: Similar rooms, similar temperature, similar heart health, same time in areas, same kind of environment, etc.

Final answer:

In John's experiment, the independent variable is the condition of the groups (listening to music or sitting in silence), the dependent variables are pulse and blood pressure, and the control variables could include room temperature, the timing, the duration of the experiment, and the use of consistent measurement devices.

Explanation:

In this experiment conducted by John, the independent variable is the condition under which each group is placed—which is, one group listening to soothing music and the other group sitting in silence. This is the independent variable because it's the factor that John changes or manipulates during the experiment.

The dependent variables here would be the pulse and blood pressure of the individuals in both groups. These variables are considered dependent because their values may change based on the effect of the independent variable (i.e., the type of noise the group is subjected to).

The constants, or control variables, in this experiment could include the room temperature, the timing of the experiment, the duration for which the conditions are applied (the length of the song), and the same pulse and blood pressure checking device, among others. These are the factors that remain the same throughout the experiment to ensure that the results are only influenced by the independent variable and not by any other factors.

A tee-ball team for 5 year-olds has half as many girls as boys. If there are 15 children on the team, how many are boys and how many are girls?

Answers

there are 10 boys because half of 10 is 5 5+5 equals 10

As the has half as many females as males, the number of males in the team is 10, and the number of females in the team is 5.

What is the number of males and females in the team?

Given the parameter:

A team for 5-year-olds has half as many females as males.

There are 15 children on the team.

There are half as many females as males, this can be expressed as:

Let G represents females and B represents males.

G = 0.5B

Also, there are 15 children on the team, so we can write an equation based on the total number of children:

B + G = 15

Now, we solve the system of equations:

G = 0.5B

B + G = 15

First, substitute the expression for females from the first equation into the second equation:

B + 0.5B = 15

1.5B = 15

B = 15/1.5

B = 10

Plug B = 10 into the first equation and solve for females:

B + G = 15

10 + G = 15

G = 15 - 10

G = 5

So, there are 10 males and 5 females on the team.

What are Amino acids?

Amino acids may be defined as compounds that significantly contain carbon, hydrogen, oxygen, and nitrogen. These compounds serve as the monomers or the building blocks of proteins that are composed of an amino group, a carboxyl group, a hydrogen atom, and a specific side chain.

Two amino acids are held together by a linkage known as peptide linkage. When a number of peptide linkages are present in the structure of the protein, it is known as polypeptides.

If any polypeptide chain is derived from 20 amino acids. So, the possibility of a combination for any polypeptide chain will be [tex]20^n[/tex], where n = the number of amino acid residues in the polypeptide chain.

Therefore, since there are 20 standard amino acids, the number of possible linear polypeptides of length n can be expressed as [tex]20^n[/tex].

Then the storehouses were filled up once more with the tributes paid the Inca. If there came a lean year, the storehouses were opened and the provinces were lent what they needed in the way of supplies; then, in a year of abundance, they paid back all they had received. No one who was lazy or tried to live by the work of others was tolerated; everyone had to work. Thus on certain days each lord went to his lands and took the plow in hand and cultivated the earth, and did other things. Even the Incas themselves did this to set an example. And under their system there was none such in all the kingdom, for, if he had his health, he worked and lacked for nothing; and if he was ill, he received what he needed from the storehouses.Based on the excerpt, what can you conclude about the Inca government? star: a object made of gas found in outer space that radiates Suppose you were to make a ring from a single strand of gold atoms.
