What do you call a person who makes faces all day long

Answers

A person who makes faces all day is often described as expressive or animated, and may be humorously termed a 'mugger' or 'face-puller'. Facial expressions are crucial for conveying emotion in human interaction and can be particularly striking in literature and dramatic performances.

The question 'What do you call a person who makes faces all day long?' is asking about a term or description for someone who frequently changes their facial expressions. While there is no specific term that describes this behavior in a clinical or professional sense, in a colloquial context, you might call such a person expressive, animated, or if the expressions are humorous or exaggerated, a 'mugger' or 'face-puller'. In literature and drama, characters known for their expressive faces can bring a story to life or provide comic relief.

Facial expressions are an integral part of human communication. They can underscore the emotional state of a person, such as the sense of pride on the face of a monomaniacal king, the devotion seen in a religious fanatic, or the terror described in the imagery of wallpaper patterns appearing to have expressive eyes. Whether in social interactions, literature, or public speaking, the alignment of facial expressions with spoken words is important for conveying meaning and emotion.

A student is selling baked goods in the halls before school as a fundraiser. She sells cinnamon rolls, donuts, and croissants. Students purchase the goods according to the probability distribution:

X(Product): cinnamon roll, donut, croissant
P(x): 0.20, 0.55, 0.25

A): If a cinnamon roll yields $0.25 profit, a donut yields $0.20 profit, and a croissant yields a $0.30 profit, how much profit will be made on each customer?

B):If there are 50 customers, how much can you expect her to make?

Answers

a). Profit made by each customer: (0.25 * 0,2) + (0.20 * 0.55) + (0.30 * 0.25) = 0.05 + 0.11 + 0.07 = $0.235

b). Money made if there are 50 customers: $0.235 * 50 = $11.75

the equation will be y = x - 700

am i right?

Answer:
y = x - 700

Explanation:
The equation of the line in slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

1- getting the slope:
To get the slope, we will need two points from the graph. I will choose (700,0) and (0,-700)
slope = (y2-y1) / (x2-x1) = (-700-0) / (0-700) = 1
The equation now is:
y = 1x + c
y = x + c

2- getting the y-intercept:
The y-intercept means the value of the y at x = 0. We can get this directly from the graph.
From the graph, we can find that:
at x = 0, y = -700
Therefore:
c = -700

Based on the above, the equation of the line is:
y = x - 700

Math is about number sense and matching patterns. You get number sense by playing with numbers: counting, arranging. Most people do not find it difficult to match patterns, as our brains are wired to see them--sometimes even when they aren't there.

The picture below is pretty much all you need to know to answer these questions. It is a short course on arithmetic and geometric sequences. (We have left out some simplifications that can be made to the formulas for Nth term, and we have not shown formulas for the sum of a sequence.)

This can be simplified using the rules of exponents to
.. f(n) = 600*(0.1^-1)*(0.1^n)

A field is shaped like the figure shown. What is the area of the field? Use 3.14 for pi

Answers

I attached the image for this question.

Answer:
area of field = 146.24 m²

Explanation:
Noticing the figure, we can see that it is composed of three regular shapes:
1- a square
2- a triangle
3- quarter of a circle

We will get the area of each shape separately and then add them to get the total area of the field.

1- getting the area of the square:
area of the square = (side)²
we have the side = 8 m
Therefore:
area of square = (8)² = 64 m² ...............> I

2- getting the area of the triangle:
area of triangle = [tex] \frac{1}{2} [/tex] * base * height
We have the base = 8 m and the height = 8 m
Therefore:
area of triangle = [tex] \frac{1}{2} [/tex] * 8 * 8 = 32 m² ..........> II

3- getting the area of the quarter circle:
area of circle = πr²
area of quarter circle = [tex] \frac{1}{4} [/tex] * πr²
We have π = 3.14 and r = 8 m
Therefore:
area of quarter circle = [tex] \frac{1}{4} [/tex] * 3.14 * (8)² = 50.24 m² .....> III

4- getting the total area of field:
Total area of field = I + II + III
Total area of field = 64 + 32 + 50.24
Total area of field = 146.24 m²

The area of a quarter circle is 0.785 square kilometers. What is the quarter circle's perimeter?

Answers

To find the perimeter of the quarter circle, the radius is first calculated using the area, and then the perimeter formula for a circle is applied, adjusting the final calculation to include the straight edges of the quarter circle.

The student has provided the area of a quarter circle and is seeking to find its perimeter. The area of the full circle can be found by multiplying the quarter circle area by 4, yielding an area of 3.14 square kilometers (since the area of a quarter circle is 0.785 square kilometers). Using the formula for the area of a circle, A = πr², we can solve for the radius (r).

Let's calculate the radius of the circle:

A = πr² = 3.14 km²r² = A/πr² = (3.14)/(3.1415927)r = 1 km (Here we're considering π to be approximately 3.1415927)

Now, the perimeter (or circumference) of the full circle is given by the formula P = 2πr. For a quarter circle, the perimeter includes the arc of the quarter circle and the two radii.

The perimeter of the quarter circle is thus:

P = (1/4) × 2πr + 2rP = (1/4) × 2 × 3.1415927 × 1 km + 2 × 1 kmP = 1.57079635 km + 2 kmP = 3.57079635 km

But since we know the measurements are to a certain precision, we must adjust our answer accordingly:

The final perimeter of the quarter circle, rounded to an appropriate number of significant figures based on the original measurement given, is approximately 3.57 km.

deena has a set of 4 coasters on her coffee table, and each coaster is shaped like a cylinder with a height of 0.5 inches and a radius of 2.5 inches. which is the total surface area of the 4 coasters?

Answers

It’s about 188.5 in squared

Final answer:

The total surface area for the 4 cylindrical coasters, each with a height of 0.5 inches and a radius of 2.5 inches, is approximately 188.4956 square inches.

Explanation:

Deena has a set of 4 coasters, each shaped like a cylinder.

To calculate the surface area of one coaster, we need to find the area of the two circular bases and the area of the side that wraps around the cylinder (the lateral surface area).

The formula for the surface area of a cylinder is SA = 2πr(h+R), where r is the radius, h is the height, and R is the radius of the bases.

Given a height of 0.5 inches and a radius of 2.5 inches:

SA = 2π(2.5)(0.5+2.5)

SA = 2π(2.5)(3)

SA = 2π(7.5)

SA = 15π

The result is the surface area for one coaster. As we have 4 coasters, we multiply this result by 4:

Total surface area for 4 coasters = 4 × 15π ≈ 4 × 47.1239 ≈ 188.4956 square inches.

Answers

Hi there!

The first step in solving this should be to determine what mean, median, mode and range are and how to find them. 

The "mean" is essentially just the average of a set of numbers, and it's found by finding the sum of the numbers then dividing by the number of add-ins. 
The "median" is the middle number in a set. This is found by arranging the numbers from smallest to largest and finding the center number. Sometimes, if there is an even number of items in a set, you'll have to find the median by taking the mean of the two middle number. (For example, if your set is 1, 2, 3, 4 you would find the median by looking or the middle number(s) which in this case would be 2 and 3. To find the median, you'd take 2+3 which equal 5 and divide that by the number of items- 2 which gives you 2.5). 
The "mode" is the is simply whichever number occurs the most in a set. 
The "range" is the difference between the largest and smallest numbers in a set; in other words, you take the largest number in the set and subtract the smallest number in the set from it (i.e if the largest number is 5 and the smallest number is 3, you'd take 5-3 which gives you the range of 2). 

Now the, on to solving your problem! 
The set you were given consists of the numbers -9, -36, -23, -8, -17, -52, -27, and -36. 

To find the mean, we would take all of the numbers and add them up: 
-9+(-36)+(-23)+(-8)+(-17)+(-52)+(-27)+(-36) = 208
Then, you divide the sum by the number of add-ins, in this case, 8 (since there are 8 numbers in the set). 
-208/8 = -26. 
So the mean = -26. 

The median can be found next, by arranging the numbers from smallest to largest: 
-52, -36, -36, -27, -23, -17, -9, -8 
As we can see, the middle-most numbers are -27 and -23, so what we have to do is add the number which gives us -50 and divide by 2 which gives us the answer of -25. 
So the median is -25. 

Next is the mode, which can be found by seeing which number occurs the most. As we can see by looking at the set, -36 is the only number that occurs more than once (occurring twice). 
Since it occurs the most, the mode is -36. 

Finally, we need to find the range. In order to do this, we take the highest number (-8) and subtract the lowest number (-52). 
-8-(-52)= 44
Keep in mind that when you're subtracting a negative, it becomes addition. 
And there we go, the range is 44. 

So now we just have to look at your choices, and you can see that option C matches the answers, since the mean= -26, the median= -25, the mode= -36, and the range = 44. 

Truly hope this helps!

In a layout of Mark’s backyard, the ratio is 1 centimeter = 10 meters. The length of the deck on the layout is 4 cm and the width is 4 cm. What is the perimeter of Mark’s deck?

Answers

Think the answer is 10 x 4 x 4 =160

The perimeter of Mark's deck in real life is calculated by converting the layout measurements to actual measurements using the scale factor and then applying the perimeter formula. The perimeter is found to be 160 meters.

To calculate the perimeter of Mark's deck, which is represented on a layout where the scale is 1 centimeter = 10 meters, we use the perimeter formula for a rectangle: Perimeter (P) = 2 * (length + width). Since both the length and width of Mark's deck are provided as 4 centimeters each, and each centimeter corresponds to 10 meters in reality, we first convert the measurements from centimeters to meters by multiplying them by the scale factor.

Length in meters = 4 cm * 10 meters/cm = 40 meters
Width in meters = 4 cm * 10 meters/cm = 40 meters

Now, calculate the perimeter:

P = 2 * (40 meters + 40 meters)
P = 2 * 80 meters
P = 160 meters

The real-life perimeter of Mark's deck is 160 meters.

Write a function in terms of t that represents the situation.

Your starting annual salary of $35,000 increases by
4% each year.

With instructions on how you did it please!!!

Answers

Final answer:

To represent the situation, the function can be written as f(t) = 35000 × (1 + 0.04)^t, where t represents the number of years into the future.

Explanation:

To write a function in terms of t that represents the situation, we can start with the initial salary of $35,000 and then calculate the annual increase using the 4% growth rate.

We need to multiply the current salary by (1 + 0.04) to get the new salary for each year. The function can be written as:

f(t) = 35000 × (1 + 0.04)^t

Here, t represents the number of years into the future from the initial starting point.

For example, if you want to find the salary after 3 years, you can plug in t = 3 into the function.

A function that represents your annual salary starting at $35,000 and increasing by 4% each year,
[tex]S(t) = 35000 * (1 + 0.04)^t[/tex], where t is the number of years.

To create a function that represents your annual salary starting at $35,000 and increasing by 4% each year,
we use the formula for exponential growth,
[tex]final amount = initial amount * (1 + growth rate)^t^i^m^e.[/tex]
Given that your initial salary is $35,000 and the growth rate is 4% (or 0.04),
let's define the function S(t) where S represents your salary and t represents the number of years:

   [tex]S(t) = 35000 * (1 + 0.04)^t[/tex]
the initial salary=$35,000.

Convert the percentage increase to a decimal,
4% becomes 0.04.

Set up the function using the formula for exponential growth,
which is initial amount multiplied by [tex](1 + growth rate) ^t[/tex]

Thus, for any year t, the function [tex]S(t) = 35000 * (1 + 0.04)^t[/tex] calculates your annual salary.

what does it mean to "square a circle"?

Answers

it is an expression like when someone tells you good luck squaring a circle its like good luck doing the impossible

Final answer:

In mathematics, 'squaring the circle' means to create a square with the same area as a given circle, though it is impossible to achieve precisely due to the nature of π. When fitting a circle in a square, the side of the square is twice the radius of the circle, and the circle's area is approximately three-quarters that of the square.

Explanation:

To "square a circle" in mathematical terms traditionally means to create a square with the same area as a given circle, using only a finite number of steps with compass and straightedge. This problem is known to be impossible to solve exactly due to the transcendental nature of π (pi). However, when we discuss fitting a circle within a square, we often refer to having the diameter of the circle, which is twice the radius (2r), fit exactly across the side length of the square (a).

The area of the circle is πr², and when the circle fits within a square the area of the square is a². Since a = 2r, the area of the square can be expressed as 4r². From this, we can approximate that a circle's area would be less than the area of the square but more than half, possibly around three-quarters, thus approximately 3r².

Perimeter-wise, a circle within a square would have a circumference less than the perimeter of the square but significantly longer than a straight line passing through the center of the square. This understanding allows for practical estimations without requiring exact precision, which can be particularly useful in everyday contexts where an approximation suffices.
