Using the Fundamental Counting Theorem, it is found that Samantha has 36 different outfits to choose from.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the pants, there are 2 options, hence [tex]n_1 = 2[/tex].For the t-shirts, there are 2 outcomes, hence [tex]n_2 = 2[/tex].For the shoes, there are 9 outcomes, hence [tex]n_3 = 9[/tex].Thus, the total number of outfits is given by:
N = 2 x 2 x 9 = 36.

Answer:
x = 0.71; y = 2.43
Step-by-step explanation:
y = 2x + 1
y = 9x - 4
9x - 4 = 2x + 1
7x = 5
x = 5/7
y = 2x + 1
y = 2(5/7) + 7/7
y = 10/7 + 7/7

152 students study english and math
79 students study math and science
139 students study science and english
How much students are in the school?
Answer:
517
Step-by-step explanation:
We can draw a Venn diagram to represent the data.
First, identify the groups.
Let E = students who study EnglishLet M = students who study MathLet S = students who study ScienceThen draw the Venn diagram to represent the groups.
Given 73 students study all subjects:
E ∩ M ∩ S = 73 (add this to the middle section)
Next, add the numbers for the sections where the students study 2 topics.
E ∩ M but not S: 152 - 73 = 79
M ∩ S but not E: 79 - 73 = 6
S ∩ E but not M: 139 - 73 = 66
Now complete each circle by making sure that the values add up to the total value given.
Only E = 254 - S ∩ E - E ∩ M - E ∩ M ∩ S = 254 - 66 - 79 - 73 = 36
Only M = 280 - E ∩ M - M ∩ S - E ∩ M ∩ S = 280 - 79 - 6 - 73 = 122
Only S = 280 - M ∩ S - S ∩ E - E ∩ M ∩ S = 280 - 6 - 66 - 73 = 135
To find the total number of students in the school, add the numbers in each section of the Venn diagram:
73 + 79 + 6 + 66 + 36 + 122 + 135 = 517

Answer:
see explanation
Step-by-step explanation:
you are looking for perfect square factors of the numbers under the radical sign. both numbers and the sum are irrational because they contain √5
125 = 5×25
80 = 5×16
3√125 = 3√(25×5) = 3×5√5 = 15√5
√80 = √(16×5) = 4√5
1) 15√5 + 4√5 = 19√5 the √5 is the same square root so you add the coefficients
perfect square factors are bold
4×√(25×2)×√(9×2) =
4×5×3×√(2×2) =
60×√4 =
2) 60 × 2 = 120
the numbers are both irrational but the answer is rational because √2 ×√2 = √4 = 2

Answer: hope this helps! :)
t - 4

t - 6
Step-by-step explanation:
t2 + 2t - 24
Simplify ————————————
t2 - 36
Trying to factor by splitting the middle term
Factoring t2 + 2t - 24
The first term is, t2 its coefficient is 1 .
The middle term is, +2t its coefficient is 2 .
The last term, "the constant", is -24
Multiply the coefficient of the first term by the constant 1 • -24 = -24
Find two factors of -24 whose sum equals the coefficient of the middle term, which is 2 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5
-6 + 4 = -2
-4 + 6 = 2 That's it
Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 6
t2 - 4t + 6t - 24
Add up the first 2 terms, pulling out like factors :
t • (t-4)
Add up the last 2 terms, pulling out common factors :
6 • (t-4)
Step-5 : Add up the four terms of step 4 :
(t+6) • (t-4)
Which is the desired factorization
Trying to factor as a Difference of Squares :
1.2 Factoring: t2-36
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 36 is the square of 6
Check : t2 is the square of t1
Factorization is : (t + 6) • (t - 6)
Canceling Out :
Cancel out (t + 6) which appears on both sides of the fraction line.

Find the values of the variables:
Answer:
x = 150
y = 30
Step-by-step explanation:
x° = 5y° (corresponding angles) (1)
x° + y° = 180° (Linear pair angles) (2)
From equations (1) and (2), we find:
5y° + y° = 180°
-> 6y° = 180°
-> y° = 180°/6
-> y° = 30°
-> y= 30
-> x° = 5(30°) = 150° (From equation 1)
-> x = 150

The equation that represents the number of T-shirt , number of colours of shirt and total order is 3x + 50xy.
The number of colours and T- shirts are the variable quantity while the cost of order is the fixed quantity.
How to represent an equation ?The number of members in the school choir = 75
The charge for one shirt = $3
Let the number of T-shirts ordered be x
Cost of ordering x shirts = 3x
Therefore,
Charge for each colour to be printed = $50
Let the number of colours to be printed on each T- shirt be represented by y
Therefore,
Cost of printing y colours on each T- shirt = 50y
Cost of printing y colours on x number of T-shirts = x(50y) = 50xy
Hence, the equation that represents the number of T-shirt , number of colours of shirt and total order is as follows:
Total cost = 3x + 50xy
Hence, the fixed quantity and variable quantity are as follows:
The number of colours on the shirts is a variable quantity

Using a system of equations, it is found that:
126 children attended.88 students attended.63 adults attended.What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Number of children that attended.Variable y: Number of students that attended.Variable z: Number of adults that attended.The theater was full, hence:
x + y + z = 277.
There are half as many adults as there are children, hence:
x = 2z.
The theater charges $5.00 for children, $7.00 for students, and $12.00 for adults. The total ticket sales were of $2002, hence:
5x + 7y + 12z = 2002.
Replacing the second equation into the other two:
y + 3z = 277 -> y = 277 - 3z
7y + 22z = 2002.
Then:
7(277 - 3z) + 22z = 2002
z = 63
y = 277 - 3z = 277 - 3 x 63 = 88
x = 2z = 2 x 63 = 126.

Points (1,1) & (3,-4)To find:
Distance between two pointsDistance Formula:
[tex]\displaystyle \large{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]

Therefore, the number inside the radical is 29
Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
Hi there!
We are given the points (1, 1) and (3, -4)
We want to find the distance between the points
Distance can be found using the formula [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We can label the values of the points first, before calculating to help avoid confusion and mistakes.
[tex]x_1 = 1\\y_1 = 1\\x_2 = 3 \\y_2 = -4[/tex]
Now substitute these values into the formula
d = [tex]\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
d = [tex]\sqrt{(3-1)^2 + (-4-1)^2}[/tex]
Now, using order of operations, first simplify what is in the parentheses:
d = [tex]\sqrt{(2)^2 + (-5)^2}[/tex]
Now raise 2 and -5 to the second power.
d = [tex]\sqrt{4 + 25}[/tex]
Add the numbers together under the radical
d = [tex]\sqrt{29}[/tex]
The distance is [tex]\sqrt{29}[/tex]

Mary is 63.5 inches tall and her sister Tonya is 70 inches tall. Tonya wants to know how many inches taller she is than Mary. Which equation and solution can be used to solve this problem?
x + 70 = 63.5: Subtract 70 from both sides. The answer is 6.5 inches.
63.5 + x = 70: Subtract 63.5 from both sides. The answer is 6.5 inches.
x minus 63.5 = 70: Add 63.5 to the left side and subtract 63.5 from the right side. The answer is 6.5 inches.
63.5 minus x = 70: Subtract 63.5 from both sides. The answer is 6.5 inches.
Answer: second option
Step-by-step explanation: Mary's age plus X = 70
63.5 + X = 70
Subtract 63.5 from both sides

40 feet wide and 96 feet long how far is it from 1 corner to the opposite corner
Answer:
104 feet
Step-by-step explanation:
The Pythagorean theorem can be used to find the hypotenuse of a right triangle with legs 40 feet and 96 feet. It tells you ...
h² = 40² +96²
h² = 1600 +9216 = 10816
h = √10816 = 104
The distance from one corner to the opposite corner is 104 feet.
______
Additional comment
You may recognize that the ratios of the given lengths are 40:96 = 5:12. These match the legs in the Pythagorean triple (5, 12, 13). This tells you the third side (diagonal) of the triangle is 13 ratio units, or 13×(8 ft) = 104 ft.
