Hello do you no how to do Solving Equations Puzzle
1 - The right and the left side must weight the same, and the weight of both the right and the left side would be 24, therefore each side must weight 12.
2 - Since the heart = 2, and 2*heart + square = 12 , then square = 8
3 - Now, since square = 8 and square + moon = 12, then moon=4
To summarize
heart = 2, square = 8 , moon = 4.
I don’t know wether it is a independent or dependent variable.
To determine whether they are dependent or independent events:
1. According to the problem, Event 1 is a selection of a tile J out of 26 and the Event 2 is a selection of v in the remaining 25 tiles.
Event 1 affects event 2.
So, these are dependent events.
2. Similar to the first question, event 1 affects event 2. Because event 2 is depending on the first event.
So, these are dependent events.
3. According to the problem, event 1 does not affect event 2.
So, these are independent events.
4. According to the problem, she selects one trading card and then she returns the card back. After this, she selects the other card. So, event 1 does not affect event 2.
So, these are independent events.
5. Similarly to the fourth question, event 1 does not affect event 2 because of the dropped back of balls.
So, these are independent events.

Answer:
Li worked for 19 hours.
Explanation:
Let's call x the number of hours that Vic worked, y the number of hours that Sam worked, and z the number of hours that Li worked.
They all work for 52 hours, so:
x + y + z = 52
Sam worked 3 fewer hours than Vic and 4 fewer than Li, so:
y = x - 3 or y + 3 = x
y = z - 4 or y + 4 = z
So, we can replace x and z on the first equation and solve for y as:
(y + 3) + y + (y + 4) = 52
y + 3 + y + y + 4 = 52
3y + 7 = 52
3y + 7 - 7 = 52 - 7
3y = 45
3y/3 = 45/3
y = 15
Then, replacing y by 15, we can calculate the value of x and z as:
x = y + 3
x = 15 + 3
x = 18
z = y + 4
z = 15 + 4
z = 19
Therefore, Li worked for 19 hours.

The missing zero is:

i
The expanded polynomial is:
x3 +
x2 +
x +
The equation of the polynomial equation in standard form is P(x) = x³ - 25x²+ 209x - 585
How to determine the polynomial expression in standard form?The given parameters are
Degree = 3
Zero = 9, 8 - i
There are complex numbers in the above zeros
This means that, the other zeros are
Zeros = 8 + i
The equation of the polynomial is then calculated as
P(x) = (x - zero)^multiplicity
So, we have
P(x) = (x - 9) * (x - (8 - i)) * (x - (8 + i))
This gives
P(x) = (x - 9) * (x - 8 + i) * (x - 8 - i)
Evaluate the products
P(x) = (x - 9) * (x² - 8x - ix -8x + 64 + 8i + ix - 8i + 1)
Evaluate the like terms
P(x) = (x - 9) * (x² - 16x + 65)
Express in standard form
P(x) = x³ - 16x² + 65x - 9x² + 144x - 585
Evaluate the like terms
P(x) = x³ - 25x²+ 209x - 585
Hence, the equation is P(x) = x³ - 25x²+ 209x - 585

To find:
The solution of the given inequality -4x < 8.
Solution:
Given inequality is -4x < 8. Divide both sides by -4 to isolate x.
If we divide an inequality by a negative number, then the sign of inequality changes to its opposite. So, on dividing the inequality by -4,we get:

Given g(x) =9x^2-18x+11, for what value (s) is g(x) =23
The values of x for which g(x) = 23 are x = 2.53 and x = -0.53
Determining the values of x for which g(x) = 23From the question, we are to determine the value(s) for which g(x) = 23
From the given information,
The function is
g(x) = 9x² - 18x + 11
Now, we will substitute g(x) = 23
That is,
23 = 9x² - 18x + 11
Rearranging
9x² - 18x + 11 - 23 = 0
9x² - 18x - 12 = 0
Divide through by 3
3x² - 6x - 4 = 0
Now, solve the quadratic equation
3x² - 6x - 4 = 0
Using the general formula,
x = [-b±√(b²-4ac)]/2a
a = 3, b = -6, c = -4
x = [-(-6)±√((-6)²-4(3)(-4))]/2(3)
x = [6±√(36 + 48)]/6
x = [6±√(84)]/6
x = [6 ± 9.17]/6
x = [6 + 9.17]/6 OR x = [6 - 9.17]/6
x = 15.17/6 OR x = -3.17/6
x = 2.53 OR x = -0.53

Please help, due in 3 minutes Skylar still owes $550 oh her cresit card from the previous month. Her annual interest rate is 18%. Approximately how much should the interest charges Be when she gets the bill
Answer:
$8.25
Explanation:
If she gets the bill each month, we need to calculate the monthly interest rate as follows
18%/12 = 1.5%
Because 18% is the annual rate and a year has 12 months.
Then, the interest charge will be 1.5% of the amount, so
$550 x 1.5% = $550 x 1.5 / 100 = $8.25
Therefore, the interest will be $8.25

The perimeter of a geometric figure is the sum of the lengths of its sides. If the perimeter of the pentagon to the right (five-sided figure) is 80 meters, find the length of each side.
Answer:
16 m
Step-by-step explanation:
If the perimeter of an equilateral pentagon is 80 m and it has five sides, the length of each side must be 16 m:
[tex]x=\frac{80}{5}[/tex]
[tex]x=16[/tex]
Therefore, if each side is 16 m in length, 2½ sides must equal 40 m:

Hello! I need some help with this homework question, please? The question is posted in the image below. Q21
To find the zeros of the polynomial given, we will first have to find some simpler zeros first then factor the polynomial so we can use the quadratic equation.
Since we can assume this question is to be solved without external tools, it is likely that two of the roots are simple ones.
So, we can try to use the rational root theorem to find these simpler ones.
Since the leading coefficient is 1 and the constant term is -18, if there are rational roots, they can be written as a fraction of a factor of -18 divided by a factor of 1.
The only factor of 1 is 1, so we now that if there are rational roots, they have to have denominator equal to 1.
The factors of 18 are 1, 2, 3, 6, 9 and 18.
Also, we have to consider the possibilities of positive and negative.
It is easier to test the lower ones, so let's start by testing 1/1 and -1/1. For either to be a zero, the polynomial has to result in 0:
[tex]\begin{gathered} x^4+x^3+7x^2+9x-18 \\ x=1 \\ 1^4+1^3+7\cdot1^2+9\cdot1-18=1+1+7+9-18=18-18=0 \end{gathered}[/tex]So, x = 1 is a zero of the polynomial.
[tex]\begin{gathered} x^4+x^3+7x^2+9x-18 \\ x=-1 \\ (-1)^4+(-1)^3+7(-1)^2+9(-1)-18=1-1+7-9-18=-2-18=-20 \end{gathered}[/tex]So, x = -1 is not a zero.
Now, let's try the next factor, 2/1 and -2/1:
[tex]\begin{gathered} x^4+x^3+7x^2+9x-18 \\ x=2 \\ 2^4+2^3+7\cdot2^2+9\cdot2-18=16+8+28+18-18=52 \end{gathered}[/tex]So, x = 2 is not a zero.
[tex]\begin{gathered} x^4+x^3+7x^2+9x-18 \\ x=-2 \\ (-2)^4+(-2)^3+7(-2)^2+9(-2)-18=16-8+28-18-18=8+10-18=0 \end{gathered}[/tex]So, x = -2 is also a zero of the polynomial.
We could continue, by we only need 2 zeros, so this is enough.
Now we know x = 1 and x = -2 are zeros of the polynomial, we can use synthetic division to factor the polynomial:
1 | 1 1 7 9 -18
| 1 2 9 18
| 1 2 9 18 0
Using the last line, we have that the remainder is 0 and the quotient is:
[tex]x^3+2x^2+9x+18[/tex]So, we have that:
[tex]x^4+x^3+7x^2+9x-18=(x-1)(x^3+2x^2+9x+18)[/tex]Now, we can use synthetic division again on the quotient, but now use the other zero, x = -2:
-2 | 1 2 9 18
| -2 0 -18
| 1 0 9 0
Since x = -2 is a zero, we also got a remainder of 0, and the quotient is:
[tex]\begin{gathered} x^2+0x+9 \\ x^2+9 \end{gathered}[/tex]So, we can rewrite the polynomial as:
[tex]x^4+x^3+7x^2+9x-18=(x-1)(x+2)(x^2+9)[/tex]Now, we can just find the zeros of the remainer factor, x² + 9, so:
[tex]\begin{gathered} x^2+9=0 \\ x^2=-9 \\ x=\pm\sqrt[]{-9} \\ x=\pm\sqrt[]{9}\sqrt[]{-1} \\ x=\pm3i \end{gathered}[/tex]This means that the complex zeros of the given polynomial are:
[tex]\begin{gathered} x=1 \\ x=-2 \\ x=3i \\ x=-3i \end{gathered}[/tex]And the factored usinf complex factors is:
[tex]x^4+x^3+7x^2+9x-18=(x-1)(x+2)(x-3i)(x+3i)[/tex]
