While shopping for school
supplies, Ashton buys two 3-ring binders, three packages of
pencils, and two erasers. If he pays using a $20 bill, how much
change will he receive? Eraser : 0.75 package of pencils : 1.50. 3-ring binder : 2.75
Answer:
$8.5
Step-by-step explanation:
Oki, so you have your info laid out. Find out the payment of each material with how much of each material then add it up and subtract from 20. For an easier way, I'll show you.
Two 3-ring binders, each 3-ring binder costs 2.75 so you'll have 2.75 x 2, which equals up to 5.5
Three packages of pencils, each package costs 1.50, therefore it's 1.50 x 3, which is 4.5
Next, two erasers, each one being .75 cents, .75 x 2 is 1.5
Now, add them all. 5.5 + 4.5 + 1.5 = 11.5
Subtract that from $20, 20 - 11.5 = 8.5
Ashton will get $8.5 back.

There are $1.95 worth of nickels and quarters in a piggy bank there are three more nickels than quarters how many of each are in the piggy bank write how you got the answer please
Answer:
6 quarters and 9 nickels
Step-by-step explanation:
alright so this took me like an hour or two to figure out cause I'm stubborn. but I wanted to give an in depth answer
..
1) first we need to know how to write it.
___=___+___
1.95 is the full value of all of the coins so it goes here. (___)=___+___
1.95=___+___
We will use q for number of quarters and n for number of nickels. the value of a quarter .25 and the value of a nickel is .05. put the value of a quarter here. ___=(___)+___
1.95=.25q+___
we will put the value of the nickel here ___=___+(___)
1.95=.25q+.05n
now that we know how to write it, we can move onto step two.
2) figuring out what variable n is
n=___
Since we know that there are three more nickels than quarters, we can start to solve this equation.
n=q+3
3) change (n) to (q+3). dont forget to use parenthesis!
1.95=.25q+.05(q+3)
4) i forget what its called but multiply .05 throughout your parenthesis. ill show you.
1.95=.25q+.05(q+3)
.05*q= .05q and .05*3=.15
1.95=.25q+.05q+.15
5) add variables together.
1.95=.30q+.15
6) subtract .15 from both sides to get rid of it.
1.95=.30q+.15
-.15 -.15
1.80=.30q
7) divide .30 from both sides to isolate the q and get the answer of quarters
1.80=.30q
/.30 /.30
6=q
8) add three to the number of quarters to get the number of nickels.
6+3=9 nickels
Here we need to create and solve a system of equations to find the number of coins in the piggy bank.
We will see that there are 6 quarters and 9 nickels.
let's define the variables:
x = number of nickels in the piggy bank
y = number of quarters in the piggy bank.
Knowing that the total value of the coins in the piggy bank is $1.95, then we have:
x*$0.05 + y*$0.25 = $1.95
We also know that there are 3 more nickels than quarters, then we also have:
x = y + 3
Then the system of equations is:
x*$0.05 + y*$0.25 = $1.95
x = y + 3
To solve this, we can see that x is isolated in the second equation, so we can replace it in the other equation to get:
(y + 3)*$0.05 + y*$0.25 = $1.95
Now we can solve this for y:
y*$0.05 + 3*$0.05 + y*$0.25 = $1.95
y*$0.30 + $0.15 = $1.95
y*$0.30 = $1.95 - $0.15 = $1.80
y = ($1.80)/($0.30) = 6
So we have 6 quarters.
Then the number of nickels is given by:
x = y + 3 = 6 + 3 = 9
x = 9
There are 9 nickels.

Find y.
Round to the nearest tenth:
29
500 ft
Answer:
y ≈ 242.4 ft
Step-by-step explanation:
The angle on the right of the triangle = 29° ( alternate angle )
Using the sine ratio in the right triangle
sin29° = \(\frac{opposite}{hypotenuse}\) = \(\frac{y}{500}\) ( multiply both sides by 500 )
500 × sin29° = y , then
y ≈ 242.4 ft ( to the nearest tenth )

e ohio lottery has a game called pick 4 where a player pays $1 and picks a four-digit number. if the four numbers come up in the order you picked, then you win $3900. a) write the probability distribution for a player's winnings. fill in the table below. for the computer to grade this one correctly make sure that your x values are from smallest to largest.
The probability of winning $3,899 is 0.0001, which is a very small probability, but still possible.
To write the probability distribution for a player's winnings in the Pick 4 game, we need to consider all the possible outcomes and their probabilities.
There are a total of 10,000 possible four-digit numbers that can be drawn in the game. Since the player has to match the numbers in the exact order, there is only one winning combination for each four-digit number. Therefore, the probability of winning is 1/10,000.
To calculate the player's winnings, we need to subtract the $1 cost of playing from the $3,900 prize. Thus, the player's net winnings can be calculated as follows:
Net Winnings = $3,900 - $1 = $3,899
The probability distribution for the player's winnings can be summarized in the following table:
| Winnings (x) | Probability (P) |
|--------------|-----------------|
| $0 | 0.9999 |
| $3,899 | 0.0001 |

Q2:
Find the distance between the skew lines with parametric equations
x = 2 + t, y = 3 + 6t, z = 2t,
and
x = 1 + 2s, y = 6 + 14s, z = −2 + 5s.
The given equation 3x^2 - y^2 + z^2 = 0 represents a surface known as an elliptic paraboloid. To sketch this surface using traces, we can fix one variable (either x, y, or z) and vary the other two to observe the resulting curve.
Let's fix x at a constant value of 0. Substituting x = 0 into the equation, we get -y^2 + z^2 = 0. This equation represents a pair of intersecting lines, forming a trace. By varying x and fixing y or z, we can obtain additional traces, which are also pairs of intersecting lines.
Thus, by considering multiple traces, we can sketch the elliptic paraboloid surface, which resembles a bowl or a saddle. The traces consist of intersecting lines that form a grid-like pattern on the surface.
Now, moving on to the second question, we are given two skew lines with parametric equations. To find the distance between these lines, we can use the closest distance formula.
First, we need to find a point on each line. By setting t = 0 in the first line's equations, we find a point (2, 3, 0). Similarly, setting s = 0 in the second line's equations gives us a point (1, 6, -2).
Next, we find the direction vectors for both lines. The direction vector for the first line is <1, 6, 2>, and for the second line is <2, 14, 5>.
Using the closest distance formula, we can calculate the distance between the two lines as follows:
distance = |(2-1, 3-6, 0+2) · (1, 6, 2) x (2, 14, 5)| / |(1, 6, 2) x (2, 14, 5)|
Simplifying this expression will give us the distance between the skew lines.
Please note that the exact calculations are omitted here, but following the steps outlined above will provide the desired distance.

if a vat fo acid can be filled by in 10 hours and it takes 20 hours to empty how long will it take to fill if both pipes are open
This is because when both pipes are open, the net rate of filling is the difference between the rate of filling and the rate of emptying, which is V/10 - V/20 = V/20. Therefore, it will take 20 hours to fill the vat.
Let the volume of the vat be V. Then, the rate of filling is V/10 per hour, and the rate of emptying is V/20 per hour. When both pipes are open, the net rate of filling is the difference between the rate of filling and the rate of emptying, which is V/10 - V/20 = V/20. Therefore, the time required to fill the vat is V/(V/20) = 20 hours.
In summary, if a vat can be filled by in 10 hours and it takes 20 hours to empty, the time required to fill the vat with both pipes open is 20 hours. This is because when both pipes are open, the net rate of filling is the difference between the rate of filling and the rate of emptying, which is V/10 - V/20 = V/20.

What are the factors of 216?
Finding the factors of a number is important because it gives us information about the number itself and the other numbers it can be divided by evenly. The factors of 216 are 1, 2, 3, 4, 6, 9, 18, 27, 54, and 216.
Factors are numbers that divide into another number evenly, without leaving a remainder. The factors of a number give us information about the number itself and what other numbers it can be divided by. In this case, we'll find the factors of 216.
To find the factors of a number, we divide the number by other numbers until we can't divide any further. The numbers we used to divide are the factors of the original number. For example, to find the factors of 216, we could start with 2, which divides into 216 evenly. We then divide 216 by 2, giving us 108. We can then continue dividing by 2, which will give us 54, 27, and so on. We can stop when we reach a number that can't be divided evenly anymore. In this case, the factors of 216 are 1, 2, 3, 4, 6, 9, 18, 27, 54, and 216. These are all the numbers that can divide into 216 evenly, without leaving a remainder. It's important to note that factors come in pairs. For example, if 9 is a factor of 216, then its pair is 216 divided by 9, which is 24. If we list the factors in order, we can see that they come in pairs like this: (1, 216), (2, 108), (3, 72), (4, 54), (6, 36), (9, 24), and so on. This pattern is true for all numbers, not just 216.

What is the key underlying assumption of the single index
model?
The key underlying assumption of the single index model is that the return of a security can be explained by the return of a broad market index.
This assumption forms the basis of the single index model, also known as the market model or the capital asset pricing model (CAPM).
In this model, the return of a security is expressed as a function of the return of the market index. The single index model assumes that the relationship between the returns of a security and the market index is linear.
It suggests that the risk and return of a security can be explained by its exposure to systematic risk, which is represented by the market index.
The single index model assumes that the return of a security can be decomposed into two components: systematic risk and idiosyncratic risk.
Systematic risk refers to the risk that cannot be diversified away, as it affects the entire market. Idiosyncratic risk, on the other hand, is the risk that is specific to a particular security and can be diversified away by holding a well-diversified portfolio.
The single index model assumes that the systematic risk is the only risk that investors should be compensated for, as idiosyncratic risk can be eliminated through diversification.
It suggests that the expected return of a security is determined by its beta, which measures its sensitivity to the market index. A security with a higher beta is expected to have a higher return, as it is more sensitive to market movements.

What is rate?
a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.
initial population = 3000
population increase every year = 2.5% of 3000
which is 2.5/100 x 3000 = 75
let the time taken to reach 4600 be d
increment for d number of years = 75d
Total population after d years is 75d + 3000
so 75d + 3000 = 4600
75d = 4600 - 3000
75d = 1600
d = 1600/75

Assuming a roughly even distribution of birthdays throughout the year, we can estimate that approximately 1/365th of students (or 0.27%) were born on January 1st.
Determining the most probable number of students born on January 1st requires some statistical analysis. To start, we would need data on the number of students enrolled in the relevant grade level, as well as data on the distribution of birthdays throughout the year. Assuming a roughly even distribution of birthdays throughout the year, we can estimate that approximately 1/365th of students (or 0.27%) were born on January 1st. However, this estimate may not hold true for all populations. For example, some cultures may place a greater emphasis on giving birth on auspicious dates, such as New Year's Day.To get a more accurate estimate, we could look at past enrollment data for the school or district and see how many students in that age range were born on January 1st. We could also look at national birth statistics to see if there are any trends in the number of babies born on this date.Ultimately, the most probable number of students born on January 1st will depend on a variety of factors, including the size of the student population and the specific demographics of the school or district.

Write the equation of the line in slope-interpret form. Explain
Answer:
y = -½x + 4
Step-by-step explanation:
Equation of any line in slope-intercept form is y = mx + b, where,
m = slope = change in y/change in x
b = y-intercept = the point on the y-axis intercepted by the line.
Let's find m and b.
✔️Using two points on the line, (0, 4) and (2, 3),
Slope (m) = change in y/change in x = (3 - 4)/(2 - 0)
m = -1/2 = -½
✔️The line intercepts the y-axis at y = 4.
Therefore,
b = 4
✔️To write the equation of the line, substitute m = -½ and b = 4 into y = mx + b.
Thus,
y = -½x + 4
