The permutation shows that when one has been cast yet, the different ways that are there to cast Fantine from the 28 women is 28.
How to calculate the value?The different ways that are there to cast Fantine from the 28 women will be:
= 28!/(28 - 1)!
= 28!/27!
= 28
When Fantine has already been cast, the number of ways that are there to cast adult Cosette from the remaining women will be:
= 27!(27 - 1)!
= 27!/26!
= 26
When Fantine and adult Cosette have already been cast, the different ways that are there to cast Éponine from the remaining women is:
= (28 - 2)!/(28 - 2 - 1)!
= 26!/25!
= 25

Mr. Gatting poured the same amount of pepper into each of the cylindrical pepper shakers shown below. The pepper in the shaker on the left is
filled to a height of 45 millimeters.
60 mm
OA 60 millimeters
OB. 95 millimeters
-32 mm
To what approximate height is the shaker on the right filled with pepper?
24 mm-
Note: Figures are not drawn to scale
100 mm
Answer:
80 mm
Step-by-step explanation:
the same amount (and that means the same volume) of pepper is in each shaker.
the volume of a cylinder is
base area × height = pi×r² × height
with r being the radius (which is always half of the diameter).
the volume of the filled in pepper in the first shaker is then
pi×(32/2)²×45 = pi×16²×45 = pi×256×45 = 11,520pi mm³ =
= 36,191.14737... mm³
now let's see what height in the second shaker we will reach by filling the same 11,520pi mm³ of pepper into it.
so, we have
pi×(24/2)²×height = 11,520pi
12²×height = 11,520
144×height = 11,520
height = 11,520/144 = 80 mm
so, the shaker on the right is filled up to 80 mm with pepper.
Answer:
80 mm

A disk is in the form of square and measures 5.25 inches on each side. Find
the diagonal length of the disk?
Answer:
The diagonal length of the desk is 7.42462120246 inches.
Step-by-step explanation:
Since it is a square then all sides are equal which means we can easily formulate the pythagorean theorem on the diagonal length of the desk.
a^2 + b^2 = c^2
A and B are the same (width and length) since it is a square.
5.25^2 + 5.25^2 = c^2
27.5625 + 27.5625 = c^2
55.125 = c^2
Put c^2 under a square root (apply to both sides)
square root of 55.125 = 7.42462120246 = c

The length of the longer leg of a right triangle is 3 cm more than three times the length of the shorter
leg. The length of the hypotenuse is 4 cm more than three times the length of the shorter leg. Find the
side lengths of the triangle.
Length of the shorter leg:________ cm
Length of the longer leg:
cm
Length of the hypotenuse:
_cm
Answer:
the length of the shorter leg : 7 cm
the length of the longer leg : 24 cm
the length of the Hypotenuse : 25 cm
Step-by-step explanation:
a = 3b + 3
c = 3b + 4
and we know the general Pythagoras :
c² = a² + b²
(3b + 4)² = (3b + 3)² + b²
9b² + 24b + 16 = 9b² + 18b + 9 + b²
24b + 16 = 18b + 9 + b²
6b + 7 = b²
b² - 6b - 7 = 0
the general solution to such a quadratic equating is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x is called b.
a = 1
b = -6
c = -7
b = (6 ± sqrt((-6)² - 4×1×-7))/(2×1) = (6 ± sqrt(36 + 28))/2 =
= (6 ± sqrt(64))/2 = (6 ± 8)/2
b1 = (6+8)/2 = 14/2 = 7 cm
b2 = (6-8)/2 = -2/2 = -1 cm
a negative number did not make sense for a side length, so,
b = 7 cm
is our solution for one leg.
a = 3b + 3 = 3×7 + 3 = 24 cm
c = 3b + 4 = 25 cm

Create a tree diagram for flipping an unfair coin two times. The probability of H is 2/3 and probability of T is 1/3. Write the probabilities on each branch.
The probabilities on each branch are shown in the tree diagram, and P(HT) = 2/9.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The probability of H is 2/3 and the probability of T is 1/3.
P(HT) = P(H in the first trial)P(T in the second trial)
From the tree diagram:
P(HT) = (2/3)(1/3) = 2/9
Thus, the probabilities on each branch are shown in the tree diagram, and P(HT) = 2/9.

If sin(θ)=−24/25, and θ is in Quadrant III, then what is tan(θ/2)?
Recall the Pythagorean identity,
[tex]\sin^2(\theta) + \cos^2(\theta) = 1[/tex]
Since [tex]\theta[/tex] belongs to Q3, we know both [tex]\sin(\theta)[/tex] and [tex]\cos(\theta)[/tex] are negative. Then
[tex]\cos(\theta) = -\sqrt{1 - \sin^2(\theta)} = -\dfrac7{25}[/tex]
Recall the half-angle identities for sine and cosine,
[tex]\sin^2\left(\dfrac\theta2\right) = \dfrac{1 - \cos(\theta)}2[/tex]
[tex]\cos^2\left(\dfrac\theta2\right) = \dfrac{1 + \cos(\theta)}2[/tex]
Then by definition of tangent,
[tex]\tan^2\left(\dfrac\theta2\right) = \dfrac{\sin^2\left(\frac\theta2\right)}{\cos^2\left(\frac\theta2\right)} = \dfrac{1 - \cos(\theta)}{1 + \cos(\theta)}[/tex]
[tex]\theta[/tex] belonging to Q3 means [tex]180^\circ < \theta < 270^\circ[/tex], or [tex]90^\circ < \theta < 135^\circ[/tex], so that the half-angle belongs to Q2. Then [tex]\sin\left(\frac\theta2\right)[/tex] is positive and [tex]\cos\left(\frac\theta2\right)[/tex] is negative, so [tex]\tan\left(\frac\theta2\right)[/tex] is negative.
It follows that
[tex]\tan\left(\dfrac\theta2\right) = -\sqrt{\dfrac{1 - \cos(\theta)}{1 + \cos(\theta)}} = \boxed{-\dfrac43}[/tex]
wice a number added to a smaller number is 5. The difference of 5 times the smaller number and the larger number is 3. Let x represent the smaller number and y represent the larger number. Which equations represent the situation?
2 y + x = 5. 5 x minus y = 3.
2 x + y = 5. 5 y minus x = 3.
2 y + x = 5. y minus 5 x = 3.
2 x + y = 5. x minus 5 y = 3.
Answer:
2 y + x = 5 , 5 x − y = 3
Step-by-step explanation:
suppose x represents the smaller number and y represent the larger number.
Then
• The statement: “Twice a number added to a smaller number is 5”
means 2 y + x = 5
On the other hand,
•• The statement: “The difference of 5 times the smaller number and the larger number is 3”
means 5 x − y = 3

Find card(B) given that B={1,3,5,7,9,….9907}
The value of card(B) is card(B) = 4954
How to determine the card(B)?The set is given as:
B={1,3,5,7,9,….9907}
The above set is the set of odd numbers from 1 to 9907.
The number of elements is the cardinality
And it can be calculated using
L = a + (n - 1)d
Where
L = 9907
a = 1
d = 2
So, we have:
9907 = 1 + (n - 1)2
Subtract 1 from both sides
9906 = (n - 1)2
Divide by 2
n - 1 = 4953
Add 1 to both sides
n = 4954

Answer:
Volume: x(x+6)(x+2) Area: [tex]x^{2}[/tex] + 8x +12
Step-by-step explanation:
Volume Explanation:
To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= [tex]x^{3}[/tex] + 8[tex]x^{2}[/tex] + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.
Area:
To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= [tex]x^{2} + 2x + 6x +12[/tex] to get a final answer of [tex]x^{2} +8x +12[/tex]. This will be the formula when you find the area of the 2D figure in question.

A population of bacteria begins with 1500 bacteria and grows to 4500 in one hour.
- Find a function that represents the growth of this culture of bacteria as a function of time.
- How long does it take this culture of bacteria to double?
Thanks TT
The function that represents the growth of this culture of bacteria as a function of time is; P = 1500e^(1.0986t)
How to calculate Exponential Growth?
The formula for exponential growth is;
P = P₀e^(rt)
where;
P = current population at time t
P₀ = starting population
r = rate of exponential growth/decay
t = time after start
Thus, from our question we have;
4500 = 1500 * e^(r * 1)
4500/1500 = e^r
e^r = 3
In 3 = r
r = 1.0986
Thus, the function that represents the growth of this culture of bacteria as a function of time is;
P = 1500e^(1.0986t)
For the culture to double, then;
P/P₀ = 2. Thus;
e^(1.0986t) = 2
In 2 = 1.0986t
t = 0.6931/1.0986
t = 0.631 hours
