Suppose a charity event serves a prix fixe dinner that consists of one from each category: (1) soup or salad (not both), (2) appetizer, (3) entree, (4) dessert, and (5) beverage. The restaurant is offering five kinds of soup, three kinds of salad, four kinds of appetizers, six entrees, five desserts, and four beverages. How many different prix fixe dinners are possible
Answer:
3840
Step-by-step explanation:
Using the fundamental counting principle
The restaurant is offering five kinds of soup, three kinds of salad, four kinds of appetizers, six entrees, five desserts, and four beverages.
There are 5 independent events happening (5 prixe dinners)
(1) soup or salad (not both)
We have five kinds of soup, three kinds of salad
soup or salad (not both), = 5 + 3
= 8
(2) appetizer = 4
(3) entrees = 6
(4) dessert = 5
(5) Beverage = 4
Hence,
8 × 4 × 6 × 5 × 4
= 3840
The number of different prix fixe dinners are possible is 3840

a suit is being sold at a 20 % off (discount). The sale price is $ 270. What was the original price ?
Answer:
The original price is 337.50
Step-by-step explanation:
If we get 20% off, we still have to pay 100-20 =80%
Let x be the original price
x *80% = 270
.80x = 270
Divide each side by .80
.80x/.80 = 270/.80
x =337.50
The original price is 337.50
Answer:
the original price was $324.
Step-by-step explanation:
since 20% of $270 is $54, you add the $54 and get $324.

Answer:
11.2 feet
Step-by-step explanation:
The two furthest corners of the bed are at (8, 6) and (5, 10). To determine which is the furthest from the origin, use the distance formula.
d = √((x₂ − x₁)² + (y₂ − y₁)²)
d = √((8 − 0)² + (6 − 0)²)
d = 10
d = √((x₂ − x₁)² + (y₂ − y₁)²)
d = √((5 − 0)² + (10 − 0)²)
d = 5√5
d ≈ 11.2
Therefore, the corner at (5, 10) is the furthest from the origin, about 11.2 feet away.

The perimeter of a rectangular movie screen at a local cinema is 148 feet. If the length of the screen is 30 feet longer than the width, what is the length of the screen, in feet?
The perimeter of a rectangle = 2(l + w)
l = length
w = width
In this problem,
w = x
l = x + 30
the perimeter = 148
Let's plug our values into the perimeter formula above.
148ft = 2(x + x + 30ft)
Combine like terms.
148ft = 2(2x + 30ft)
Distribute the 2
148ft = 4x + 60
Subtract 60 from both sides
88ft = 4x
Divide both sides by 4
22ft = x
The width = x = 22ft
The length = x + 30 = 22 + 30 = 52ft

The solution set of the given set of linear inequations 2x - 1 < 4 and -5x - 3 < -3 is [tex]\left ( -\infty , 0 \right )[/tex].
What are equations and inequations?Algebraic expressions can be related to each other in many ways. When two expressions are equal to each other, they are called equations and are represented with an equal sign between them (=). When two expressions are not equal, they are called inequations and are represented by non-equal signs between them (>, <, ≥, ≤).
How to solve the given question?In the question, we are asked to solve the given inequations:
2x - 1 < 4 ... (i), and -5x -3 > -3 ... (ii).
First, we will solve (i), in the following ways:
2x - 1 < 4.
or, 2x - 1 + 1 < 4 + 1 (Adding 1 to both sides of the inequation)
or, 2x < 5 (Simplifying)
or, 2x/2 < 5/2 (Dividing both sides of the inequation by 2)
or, x < 5/2 (Simplifying)
or, x ∈ [tex]\left ( -\infty , \frac{5}{2} \right )[/tex] ...(iii)
Now, we will solve (ii), in the following ways:
-5x -3 > -3.
or, -5x - 3 + 3 > -3 + 3 (Adding 3 to both sides of the inequation)
or, -5x > 0 (Simplifying)
or, -5x/(-5) < 0/(-5) (Dividing both sides of the inequation by -5, sign of the inequality reverses as we are dividing by a negative number)
or, x < 0 (Simplifying)
or, x ∈ [tex]\left ( -\infty , 0 \right )[/tex] ...(iv)
For the solution set, we need the intersection of (iii) and (iv)
[tex]\left ( -\infty , \frac{5}{2} \right )[/tex] ∩ [tex]\left ( -\infty , 0 \right )[/tex]
= [tex]\left ( -\infty , 0 \right )[/tex]
∴ The solution set of the given set of linear inequations 2x - 1 < 4 and -5x - 3 < -3 is [tex]\left ( -\infty , 0 \right )[/tex].

Read this description of the life cycle of a mushroom. 1. A mushroom begins to grow underground as a single-celled "spore.” 2. The spore grows into multicellular structures called "hyphae.” 3. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground. 4. The sprouted mushroom then forms new spores that can enter the ground and begin the life cycle again. Which sentence about this life cycle shows that mushrooms need energy and respond to stimuli? A mushroom begins to grow underground as a single-celled “spore.” The spore grows into multicellular structures called “hyphae.” The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground. The sprouted mushroom then forms new spores that can enter the ground and begin the life cycle again.
The correct answer is C. The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground.
Explanation:
Two key features of living organisms are energy processing and response to stimuli. These two features imply organisms require nutrients, which can be taken from the environment or created through a process such as photosynthesis and they sense their surroundings and respond to it.
Moreover, these two features are exemplified by mushroom (fungi) in the sentence "The hyphae absorb nutrition and detect when conditions are right to sprout a mushroom above ground" because the first section shows the developing mushroom takes nutrients from the soil or its environment and this is essential for growing and survival. Also, the second section of the sentence shows the developing mushroom can sense its environment and respond by developing only in appropriate conditions.

C

5. Natalie has a pound bag of 1/8 pound bag of gummy worms, a 1/2 pound bag of twizzlers, and a 2/3 pound bag of chocolate. How many pounds of candy does Natalie have in all?
Step-by-step explanation:
1. Add all the different candies together
1/8 + 1/2 + 2/3=
2. Find the lowest common multiple of all the denominators
All the denominators can evenly multiply to 24 so 24 is the Lowest Common Denominator.
3. Multiply to make all the denominators 24
8x3=24 2x12=24 3x8=24
4. Whatever you did to the denominators, do the same thing to the numerators of that specific denominator.
1x3/8x3 1x12/2x12 2x8/3x8
5. Now that the denominators are the same for all the fractions, add all the numerators together.
3/24 + 12/24 + 16/24
3+12+16= 31
ANSWER: Natalie had 31/24 pounds of candy in all

These triangles are scaled copies of each other.
For each pair of triangles listed, the area of the second triangle is how many times larger than the area of the first?
Answer/Step-by-step explanation:
Recall: the ratio of the areas of two similar figures = the square of the ratio of the corresponding sides of the similar figures.
This will give us the scale factor.
The scale factor indicates how many times larger the second triangle is than the area of the first.
Let's find how many times larger is the area of the second triangle is to the first:
1. ∆ G And ∆ F
[tex] \frac{Area_{F}}{Area_{G}} = \frac{side_{F}^2}{side_{G}^2} [/tex]
[tex] \frac{Area_{F}}{Area_{G}} = \frac{6^2}{3^2} [/tex]
[tex] = \frac{36}{9} = 4 [/tex]
∆F is 4 times larger than ∆G
2. ∆ G And ∆ B
[tex] \frac{Area_{B}}{Area_{G}} = \frac{side_{B}^2}{side_{G}^2} [/tex]
[tex] \frac{Area_{B}}{Area_{G}} = \frac{2^2}{4^2} [/tex]
[tex] = \frac{4}{16} = 0.25 [/tex]
∆B is 0.25 times ∆G
3. ∆ B And ∆ F
[tex] \frac{Area_{G}}{Area_{B}} = \frac{side_{F}^2}{side_{B}^2} [/tex]
[tex] \frac{Area_{F}}{Area_{B}} = \frac{8^2}{2^2} [/tex]
[tex] = \frac{64}{4} = 4 [/tex]
∆F is 16 times larger than ∆B
4. ∆ F And ∆ H
[tex] \frac{Area_{H}}{Area_{F}} = \frac{side_{H}^2}{side_{F}^2}} [/tex]
[tex] \frac{Area_{H}}{Area_{F}} = \frac{2^2}{6^2} [/tex]
[tex] = \frac{4}{36} = \frac{1}{9} [/tex]
∆H is ⅑ times ∆F
5. ∆ G And ∆ H
[tex] \frac{Area_{H}}{Area_{G}} = \frac{side_{H}^2}{side_{G}^2} [/tex]
[tex] \frac{Area_{H}}{Area_{G}} = \frac{2^2}{3^2} [/tex]
[tex] = \frac{4}{9} [/tex]
∆G is 4/9 times ∆G
6. ∆ H And ∆ B
[tex] \frac{Area_{B}}{Area_{H}} = \frac{side_{B}^2}{side_{H}^2} [/tex]
[tex] \frac{Area_{B}}{Area_{H}} = \frac{1.5^2}{2^2} [/tex]
[tex] = \frac{2.25}{4} = 0.6 [/tex] (nearest tenth)

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 332
people entered the park, and the admission fees collected totaled 898.00 dollars. How many children and
how many adults were admitted?
Answer:
172 kids and 160 adults
Step-by-step explanation:
We can create two equations with the information given.
1.5x + 4y = 898
x + y = 332
We can then bring the x in the second equation over to the other side.
y = 332 - x
We can now plug this equation into the one before.
1.5x + 4(332 - x) = 898
We now do the distributive property on the equation and result with
1.5x + 1328 - 4x = 898
Then we can combine like terms and add 1.5x and -4x together and bring 1328 over by subtracting it from 898.
-2.5x = -430
-430 / 2.5x = 172
x = 172
x is defining how many children when to the park.
Now we just need to figure out y by subtracting it from the total amount of people (aka plugging it into the second equation)
y = 332 - 172
y= 160
We end up with
x = 172
y = 160
172 children and 160 adults
The solution to an inequality is graphed on the number line. What is another way to represent this solution set? O {x | X 4.5) O x | x2 4.5) 5 -3 -2 -1 0 1 2 3 4 5
Answer: Choice B [tex]\{x | \ x \le 4.5\}[/tex]
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as [tex]x \le 4.5[/tex] which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer [tex]\{x| \ x \le 4.5\}[/tex] which translates to "x such that x is less than or equal to 4.5"

The second angle in a triangle is 3° less than twice the first angle. The third angle measure is 8° more than twice the first angle. Find each angle
Answer: The first angle is 35°, the second angle is 67° and the third angle is 78°.
Step-by-step explanation:
Wee will represent the first angle by f,the second by s, and the third by t.
If gives us the information that the second angle is 3 less than twice the first one, that can be represent by the equation s= 2f-3 .
The third angle is 8 more than twice the first so it can also be represent by the equation t= 2f + 8 .
Now we know the interior of angles of a triangle adds up to 180 degrees. so see the measures equal 180 to solve for f.
f+ (2f+8) + (2f -3) = 180 Combine like terms on the left side
5f + 5 = 180
-5 -5
5f= 175
f = 35
So the first angle is 35 degrees.
Second angle.
s=2(35) - 3
s= 70 -3
s = 67
The second angle is 67.
Third angle.
t = 2(35) + 8
t= 70 + 8
t= 78
The third angle is 78 degrees.
Now add the angles up to see if they equal 180 degrees.
35 + 67 + 78 = 180
180 = 180
