What is the cylindrical shape?
The three-dimensional shape of a cylinder is made up of two parallel circular bases connected by a curved surface. The right cylinder is created when the centers of the circular bases cross each other. The axis, which represents the height of the cylinder, is the line segment that connects the two centers.
Given that the radius of cylindrical jar is 6 inches and the height is 10 inches.
The volume of a cylindrical shape is [tex]\pi r^2h[/tex].
Where r is the radius of the cylinder and h is the height of the cylinder.
Given that, the radius of the cylindrical jar is 6 inches and height is 10 inches.
The volume of a cylindrical shape is 3.14 × 6² × 10 = 1130.4 in³.
The number of marbles by which the jar can be filled is 1130.4/20 = 56.52 = 56 (approx.)

Yoko, Austin, and Bob have a total of $57 in their wallets. Austin has $7 less than Yoko. Bob has 2 times what Yoko has. How much does each have?
Yoko has $16 money, Austin has $9 and Bob has $32.
According to the question,
We have the following information:
Yoko, Austin, and Bob have a total of $57 in their wallets. Austin has $7 less than Yoko. Bob has 2 times what Yoko has.
Now, let's take the money Yoko has to be $x.
So, we have the following expressions for the money Austin and Bob have:
Austin = $(x-7)
Bob = $(2x)
Now, we have the following expression by adding them:
x+x-7+2x = 57
4x-7 = 57
4x = 57+7
4x = 64
x = 64/4
x = $16
Now, the money Austin has:

$9
Money Bob has:

find the mean the median the mode range and standard invitation of each data set that is obtained after adding the given content to each value (number 1)
Answers:
Mean = 43.7
Median = 44.5
Mode = doesn't exist
Standard deviation = 4.78
Explanation:
First, we need to add the constant to each value, so the new data is:
33 + 11 = 44
38 + 11 = 49
29 + 11 = 40
35 + 11 = 46
27 + 11 = 38
34 + 11 = 45
36 + 11 = 47
28 + 11 = 39
41 + 11 = 52
26 + 11 = 37
Now, we can organize the data from least to greatest as:
37 38 39 40 44 45 46 47 49 52
Then, the mean is the sum of all the numbers divided by 10, because there are 10 values in the data. So, the mean is:
[tex]\begin{gathered} \operatorname{mean}=\frac{37+38+39+40+44+45+46+47+49+52}{10} \\ \operatorname{mean}=43.7 \end{gathered}[/tex]The median is the value that is located in the middle position of the organized data. Since there are 10 values, the values in the middle are the numbers 44 and 45, so the median can be calculated as:
[tex]\operatorname{median}=\frac{44+45}{2}=44.5[/tex]The mode is the value that appears more times in the data. Since all the values appear just one time, the mode doesn't exist.
To calculate the standard deviation, we will calculate first the variance.
The variance is the sum of the squared difference between each value and the mean, and then we divided by the number of values. So, the variance is equal to:
[tex]\begin{gathered} (37-43.7)^2+(38-43.7)^2+(39-43.7)^2+(40-43.7)^2+ \\ (44-43.7)^2+(45-43.7)^2+(46-43.7)^2+(47-43.7)^2+ \\ (49-43.7)^2+(52-43.7)^2=228.1 \end{gathered}[/tex][tex]\text{Variance}=\frac{228.1}{10}=22.81[/tex]Finally, the standard deviation is the square root of the variance, so the standard deviation is:
[tex]\text{standard deviation =}\sqrt[]{22.81}=4.78[/tex]Is (4,-3) a solution to the following system of equations?X - y = 42x + y = 5
No, (4, -3) is not a solution to the system of equations
Explanation:If (4, -3) is a solution to the given system of equations, then
for x = 4, and y = -3, both of the equations are satisfied.
x - y = 4 - (-3)
= 4 + 3
= 7
This is not 4, so the first equation is not satisfied
2x + y = 2(4) + (-3)
= 8 - 3
= 5
This equation is satisfied
It is sufficient to conclude that (4, -3) is not a solution to the system of equations since it doesn't satisfy the first equation

Suppose someone wants to accumulate $120,000 for retirement in 30 years. The person has two choices. Plan A is a single deposit into an account with annual compounding and an APR of 6%. Plan B is a single deposit into an account with continuous compounding and an APR of 5.8%. How much does the person need to deposit in each account in order to reach the goal?The person must deposit $______ into the account for Plan A to reach the goal of $.The person must deposit $______ into the account for Plan B to reach the goal of $.(Round to the nearest cent as needed.)
We want to calculate the amount needed as an initial investment to have 120000 after 30 years.
Recall that the formula of annual compounding is given by the formula
[tex]S\text{ =}P\text{ \lparen1+r\rparen}^t[/tex]where P is the principal, r is the interest rate and t is the time in years. When compounded continously the formula is
[tex]S=Pe^{rt}[/tex]where the variables have the same meaning. In both cases we want to find P sucht that
[tex]S=120000[/tex]when t=30 and r is the interest rate that we are given.
So we have the following equation in the first case
[tex]120000=P\text{ \lparen1+}\frac{6}{100})^{30}[/tex]so if we divide both sides by (1+6/100)^30 we get
[tex]P=\frac{120000}{(1+\frac{6}{100})^{30}}\approx20893.22[/tex]so for Plan A 20893.22 is needed to have 120000 after 30 years.
now, we want to do the same with the second plan. We have
[tex]120000=Pe^{\frac{5.8}{100}30}[/tex]so we divide both sides by exp(5.8*30/100). So we get
[tex]P=\frac{120000}{e^{\frac{5.8}{100}\cdot30}}\approx21062.45[/tex]so for Plan B 21062.45 is needed to have 120000 after 30 years

Kevin and Randy have a jar containing 67 coins all of which are either quarters or nickels. The total value of the coins in the jar $12.75 ... how many of each type of coin do they have?
Answer:
47quarters and 20 nickel
Explanation:
Let the number of quarters be x
Let the number of nickels be y
If there are 67 coins in the jar, then;
x + y = 67 ....1
1 quarter = 0.25x
1 nickel = 0.05y
If the total value of the coins in the jar is $12.75, then;
0.25x + 0.05y = 12.75 ....2
Multiply through by 100
25x + 5y = 1275 ....2
Solve 1 and 2 simultaneously
x + y = 67 ....1 * 25
25x + 5y = 1275 ....2 * 1
Using Elimination method
________________________
25x + 25y = 1,675
25x + 5y = 1275
Subtract
25y - 5y = 1675 - 1275
20y = 400
y = 400/20
y = 20
Substitute y = 20 into equation 1;
From 1; x + y = 67
x + 20 = 67
x = 67 - 20
x = 47
This means there are 47quarters and 20 nickel.

A book store sells used books. Paperback books cost $1.00. Hardback books sell for $5.00. The store sold 100 books and made $260 from the sale, How many paperback books did the store sell?
ANSWER
60 paperback books
EXPLANATION
We have that:
Paperback books sell for $1.00
Hardback books sell for $5.00
The store sold 100 books and made $260.
Let the number of paperback books be x
Let the number of hardback books be y.
This means that:
x + y = 100 _____(1)
and
1 * x + 5 * y = 260
=> x + 5y = 260 ____(2)
We have two simultaneous equations:
x + y = 100 ____(1)
x + 5y = 260 ___(2)
From (1):
x = 100 - y
Put that in (2):
100 - y + 5y = 260
=> 100 + 4y = 260
Collect like terms:
4y = 260 - 100
4y = 160
y = 160 / 4
y = 40 books
This means that:
x = 100 - 40
x = 60 books
Therefore, 60 paperback books were sold.

[tex]\begin{gathered} y=2x+6 \\ y=\frac{1}{2}x+3 \end{gathered}[/tex]The equation has the form of slope - intercept form which is like:
[tex]y=m\cdot x+b[/tex]Where m is the slope and b is y- intercept
So,
The slope of the first equation = 2
The slope of the second equation = 1/2
The graphs of the equations are parallel when the slopes are equal
The graphs of the equations are perpendicular when the product of the slopes = -1
so,
the slopes are not equal
The product of the slopes = 2 * 1/2 = 1
So, the graphs of the equations are neither parallel nor perpendicular.
