In how many ways can the first 4 guest arrive at a party if 15 guest have been invited
Answer:
The first 4 guests can arrive at party in 1365 ways if 15 guest have been invited
Step-by-step explanation:
Total number of guests invited = 15
We are supposed to find in how many ways can the first 4 guest arrive at a party if 15 guest have been invited
We will use combination
Formula :[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
Substitute n = 15 and r = 4
So,Total no. of ways = [tex]\frac{15!}{4!(15-4)!}=1365[/tex]
Hence the first 4 guests can arrive at party in 1365 ways if 15 guest have been invited
Answer:
32,760Step-by-step explanation:
The first 4 guests can arrive in 32,760 ways.

As you can see, the cube and the cylinder are the same height and width. But, if you use their 2d counterparts, a square and a circle, a circle always takes up 78.5% of the squares area. Knowing this, we can take this knowledge and see that the cube will have a greater volume.

The point (a, b) is the top of a rectangle. After a transformation, it maps to the point (-a, b+3), what type of transformations happened?
a.) reflection over the line y= -1 and translated 3 units left
b.) reflection over the y = 1 and translated 3 units right
c.) reflection over the x-axis and translated 3 units down
d.) reflection over the y-axis and translated 3 units up
Answer:
d) reflection over the y-axis and translated 3 units up
Step-by-step explanation:
The reflection of the point across the y-axis (x,y)→ (-x,y)
b changed to b+3 so 3 units up
The type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given that point (a,b) is the top of a rectangle. And after the transformation, the point of the rectangle is (-a, b+3). Therefore,
(a,b) → Reflected over y-axis → (-a,b)(-a,b) → Translated 3 unit up → (-a, b+3)Hence, the type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.

The manager of a take-out pizza store needs to hire pizza makers and cashiers for the evening shift. The total number of employees of both kinds can be at most 16 and the ratio of cashiers to pizza makers must be at least 3 to 5. Also, each pizza maker can answer 12 phone calls per hour and each cashier can answer 4 calls per hour while the pizza shop must be able to handle at least 72 calls during peak hours.
(a) Create and graph a system of linear inequalities to model this problem
(b) Identify the solution region
(c) If each pizza maker gets $10 per hour and each cashier gets $6 hour, how many
pizza makers and how many cashiers should the manager hire in order to minimize
her cost?
Answer:
a) x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) see picture attached
c) 5 pizza makers and 3 cashiers should be hired.
Step-by-step explanation:
a) Let's define:
x: amount of pizza maker
y: amount of cashier
From conditions in the question:
x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) In the picture attached, the feasible region (also called solution region) is shown.
c) We want to minimize:
10*x + 6*y
subject to the previous restrictions.
It is known that the optimum solution is on the vertex of the feasible region (it is a linear system). Evaluating cost function at each point, we get:
10*1 + 6*15 = 100
10*5 + 6*3 = 68
10*10 + 6*6 = 136
Then, 5 pizza makers and 3 cashiers should be hired.

Answer:
25. x = 17°
26. x = 50°
Step-by-step explanation:
25. There is a straight line which means :
108 +4x = 180
solving the obtained equation
108+4x = 180
4x = 180 - 108
4x = 72
x = 72/4
x = 17°
26. Again we can see that the angles in which 101 and x + 29 exists is a straight line . which means :
101 + x + 29 = 180
101 + 29 + x = 180
130 + x = 180
x = 180 - 130
x = 50°
So the answer of question no. 25 is 18 degree.
The answer of question no 26 is 50 degree.

Carly and Simon are renting formal clothes for a wedding.
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
If this information was put into an equation, which amount would represent the y-intercept?
A.
$80
B.
$60
C.
$140
D.
$4,800
Answer:
I think its either B, or C
Step-by-step explanation:
because in a equation your looking for the y intercept and the y intercept is usually the number without x by it.
The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80 thus option (A) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given,
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
Total cost = 80 × number of hours + fixed cost
y = 86x + 80
y-intercept , x = 0
y = 60(0) + 80
y = 80
Hence"The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80".

Which characteristics will prove that DEF is a right, isosceles triangle?
Answer:
the slopes of DE and EF are opposite reciprocals make the triangle Δ DEF a right triangle.
Step-by-step explanation:
The characteristics will prove that Δ DEF is a right isosceles triangle is the lengths of DE and EF are congruent, and their slopes are opposite reciprocals.
Now, the equal sides of DE = EF make the triangle Δ DEF an isosceles triangle and the slopes of two perpendicular lines are always the opposite reciprocals.
So the correct answer would be: The lengths of DE and EF are congruent, and their slopes are opposite reciprocals.
A right-angle triangle with two equal sides forming that right angle must be a right isosceles triangle.
What is a right isosceles triangle?
A triangle that has a right-angle and two equal sides is called a right-isosceles triangle.
Characteristics will prove that ΔDEF is a right isosceles triangle are as follows:
1. A right isosceles triangle must have a right angle.
2. Two sides of it must be equal. Obviously, the hypotenuse is the biggest side of the triangle. Apart from the hypotenuse, other two sides must be same. It will make their slope with the hypotenuse equal. Hence, the triangle will be also be isosceles.

The area of a rectangle is 2x^2-7x-15. Determine binomials that represent the length and the width if this triangle
Answer:
[tex](x-5),(2x+3)[/tex]
Step-by-step explanation:
Given: area of a rectangle is [tex]2x^2-7x-15[/tex]
To find: binomials that represent the length and the width of the rectangle
Solution:
A polynomial that consists of two terms is known as binomial.
[tex]2x^2-7x-15=2x^2-10x+3x-15\\=2x(x-5)+3(x-5)\\=(2x+3)(x-5)[/tex]
Also, area of rectangle is length × breadth
So, length × breadth = [tex](2x+3)(x-5)[/tex]
So, length = 2x+3, breadth = x-5 or length = x-5, breadth = 2x+3

Answer:
? ≈ 52.3°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{19}{24}[/tex] , thus
? = [tex]sin^{-1}[/tex] ([tex]\frac{19}{24}[/tex] ) ≈ 52.3° ( to the nearest tenth )
Answer:
≈ 52.3
Step-by-step explanation:
You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin: [tex]sin^-1[/tex]
Set it up like this:
[tex]sin^-1(\frac{19}{24}) = ?[/tex]
When you solve, you get:
52.34
Round to the nearest tenth:
52.3
