Answer:
There are 288 cups left
Step-by-step explanation:
Take the amount that were there (395) and subtract the amount that were sold (177). that is the amount that are left
395-177 = 218
There are 288 cups left
after selling 177 cups, there are 218 lemon ice cups still at the snack shop.
To calculate how many lemon ice cups are still at the snack shop after some were sold, we need to perform a simple subtraction operation. The initial quantity of lemon ice cups was 395. After selling 177 cups, we subtract 177 from 395 to find out how many are left.
Here's the calculation:
Start with the initial number of lemon ice cups: 395.Subtract the number of lemon ice cups sold: 395 - 177.Calculate the remaining number of lemon ice cups: 218.So, after selling 177 cups, there are 218 lemon ice cups still at the snack shop.

Please help me out :)
Answer:
162π ft²
Step-by-step explanation:
The surface area (SA) of a sphere is
SA = 4πr² ← r is the radius
Calculate r from the volume, that is
V = [tex]\frac{4}{3}[/tex]πr³ = 972π
Multiply both sides by 3
4πr³ = 2916π ( divide both sides by 4π )
r³ = [tex]\frac{2916\pi }{4\pi }[/tex] = 729
Take the cube root of both sides
r = [tex]\sqrt[3]{729}[/tex] = 9, hence
SA = 4π × 9² = 4π × 81 = 324π
Which is the equation in slope-intercept form for the line that passes through (-2, 15) and is perpendicular to 2x + 3y = 4?
A. y = 2/3x + 18
B. y = 3/2x + 18
C. y = 3/2x - 12
D. y = -3/2x + 18
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 2x + 3y = 4 into this form
Subtract 2x from both sides
3y = - 2x + 4 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + [tex]\frac{4}{3}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{3} }[/tex] = [tex]\frac{3}{2}[/tex], hence
y = [tex]\frac{3}{2}[/tex] x + c ← is the partial equation of the perpendicular line
To find c substitute (- 2, 15) into the partial equation
15 = - 3 + c ⇒ c = 15 + 3 = 18
y = [tex]\frac{3}{2}[/tex] x + 18 → B
The equation of the line that passes through (-2, 15) and is perpendicular to 2x + 3y = 4 is y = 3/2x + 18.
Option B is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
To find the equation of the line that is perpendicular to 2x + 3y = 4, we need to first find its slope.
We can rearrange the equation into slope-intercept form (y = mx + b) by solving for y:
2x + 3y = 4
3y = -2x + 4
y = (-2/3)x + 4/3
So the slope of line 2x + 3y = 4 is -2/3.
Now,
Since we want a line that is perpendicular to this line, we know that its slope will be the negative reciprocal of -2/3, which is 3/2.
Now we have the slope and a point (-2, 15) that the line passes through.
We can use the point-slope form to write the equation:
y - 15 = 3/2(x + 2)
Simplifying:
y - 15 = 3/2x + 3
y = 3/2x + 18
Thus,
The equation of the line that passes through (-2, 15) and is perpendicular to 2x + 3y = 4 is y = 3/2x + 18.

Mateo wants to make a toy sailboat. He has two pieces of wood to choose from. His first piece of wood is a block that measures 18'' x 10" x 8". It weighs 46.65 lbs. His second piece of wood is a log of wood measuring 21" long, with an average circumference of 25.12". It weighs 39.25 lbs. The sailboat needs to float, but both blocks of wood are denser than wood usually is, and he's not sure either piece of wood will float. He doesn't want to get the water wet before he's applied a sealant, so he isn't willing to just drop them in the water to find out.
2a. Which common solid can he use to represent the block? Which common solid can he use to represent the log? (2 points)
2b. What is the density of the block in pounds per cubic inch? Give the formula for density and show your work. (3 points)
2c. What is the density of the log in pounds per cubic inch? Give the formula for density and show your work. Use 3.14 for π. (Hint: you can determine the radius from the circumference.) (3 points)
2d. Water has a density of about 0.0361 pounds/cubic inch. Anything rarer will float, and anything denser will sink. Which of the pieces of wood are suitable for making a toy boat that will float? (2 points)
Step-by-step explanation:
2a. The block of wood has the shape of a rectangular prism. The log has the shape of a cylinder.
2b. Density is mass divided by volume. We know the mass, but we need to find the volume.
Volume of a rectangular prism is:
V = whl
where w is the width, h is the height, and l is the length
V = (18)(10)(8)
V = 1440 in³
So the density is:
d = 46.65 lbs / 1440 in³
d = 0.0324 lb/in³
2c. Volume of a cylinder is:
V = πr²h
where r is radius and h is height.
The circumference is C = 2πr, so r = C / (2π).
r = 25.12 / (2*3.14)
r = 4.00
V = 3.14 (4.00)² (21)
V = 1055.04 in³
So the density is:
d = 39.25 lb / 1055.04 in³
d = 0.0372 lb/in³
2d. The block is less dense than water; the log is more dense than water. So he should make the boat out of the block.

A number by which another number is to be divided is called
Answer:
Step-by-step explanation:
If we had a division problem that read "16 divided by 8 equals 2", the 8 would be outside the division sign, the 16 would be under the division sign, and the 2 would be sitting on top of the division sign. The 8 is called the divisor, the 16 is called the dividend, and the 2 is called the quotient.
The answer you want, then, is "dividend"
The number by which another number is divided is called a divisor. This applies to many mathematical operations, including division, multiplication, and calculations involving exponents, such as in scientific notation.
Explanation:A number by which another number is to be divided is called a divisor. When we consider a division operation, we usually think of it as a 'dividend' divided by a 'divisor' equals a 'quotient'. If you take an example of 16 ÷ 4 = 4, here, 16 is the dividend (the number being divided), 4 is the divisor (the number that divides the dividend), and the resulting 4 is the quotient (the result of the division).
Similarly, this concept can be applied to complex mathematical operations such as multiplication and division in scientific notation or logarithmic expressions. For example, in scientific notation, when you want to divide two numbers, you divide the numbers out front and subtract the exponents.

Randall recorded 8 songs on his most recent CD the total length of the CD is 49 minutes find a until rate to represent the average length per song on the CF Please help I don't understand
Answer:
6.125 minutes per song
Step-by-step explanation:
Unit rates are based on a single unit of something. Like price per 1 gallon of gas; price for 1 pound of bananas; miles driven per 1 gallon of gas, etc. What we are looking for in minutes per song.
Use a proportion to solve this with minutes on top and number of songs on the bottom. We know that 49 minutes = 8 songs, and we want to know how many minutes (x) per 1 song:
[tex]\frac{min}{song}:\frac{49}{8}= \frac{x}{1}[/tex]
Cross multiply to get
8x = 49 so
x = 6.125 minutes per song
The question asked was about finding the average length of songs on a CD. We calculated this by dividing the total length of the CD (49 minutes) by the total number of songs (8), which gives us an average song length of 6.125 minutes.
Explanation:The subject of the question is average, a fundamental concept in mathematics. In this particular question, we need to find out the average length of the songs on Randall's CD. We know that the total length of his CD is 49 minutes, and he has recorded 8 songs on it. Finding the average involves dividing the total by the number of units.
The steps to find the average length per song are as follows:
Add up the total amount - in this case, it's 49 minutes.Count the number of units - here, it's 8 songs.Divide the total (49 minutes) by the number of units (8 songs).Upon carrying out this calculation, we discover that the average length of each song is approximately 6.125 minutes.

If f(4) = 12 and f '(x) ≥ 3 for 4 ≤ x ≤ 9, how small can f(9) possibly be?
Answer:
27
Step-by-step explanation:
If the slope of f(x) is no less than 3, then the value of f(9) can be no less than 27.
f(x) ≈ f(4) +f'(x)·(x-4)
f(9) = 12 +3(9 -4) = 27 . . . . . for f'(x) = 3.
For larger numbers of f'(x), f(9) will be larger.
We want to find the minimum possible value of f(9) given that:
f(4) = 12f'(3) ≥ 3 for 4 ≤ x ≤ 9We will see that the smallest value that f(9) can take is 27.
We know that the derivate of f(x) gives the slope to the tangent line to the graph of f(x) in a given point where it is evaluated.
If this slope is positive, the function is increasing. So if we want to find the minimum value for f(9), then we need to take the smallest slope possible (knowing that it is positive).
Then we must use f'(x) = 3
Now, we can integrate this to get:
f(x) = 3*x + b
Where b is a constant of integration, to find the value of b, we can use the fact that f(4) = 12, then:
12 = f(4) = 3*4 + b
12 = 12 + b
12 - 12 = 0 = b
Thus the equation is just:
f(x) = 3*x
Now we can evaluate this in x = 9 to get:
f(9) = 3*9 = 27
The smallest value that f(9) can take is 27.

Let us rewrite the first equation in slope-intercept form.
3y =-2x+ 6
[tex]y = - \frac{2}{3} x + 2[/tex]

Which of the following is not an example of exponential growth or decay? A. a t-shirt shrinks by 2% after each wash B. a one time bonus of 10% of a worker’s annual salary C. a yearly pay increase of 3% each year D. a savings account growing by 3% each year
Final answer:
Option B, a one-time bonus of 10% of a worker’s annual salary, is not an example of exponential growth or decay because it does not involve a percentage change being applied repeatedly over time to a changing base amount.
Explanation:
The question asked is: Which of the following is not an example of exponential growth or decay? The options are: A. a t-shirt shrinks by 2% after each wash, B. a one time bonus of 10% of a worker’s annual salary, C. a yearly pay increase of 3% each year, D. a savings account growing by 3% each year. To answer this, we must recognize that exponential growth or decay refers to processes that grow or decrease at a rate proportional to their current size. This means the amount of increase or decrease changes over time, as it is a percentage of an ever-changing base amount.
Options A, C, and D all describe situations where the quantity changes by a fixed percentage over time, indicative of exponential growth (or decay, in the case of shrinking). Option A discusses a t-shirt shrinking by 2% after each wash, meaning each time it shrinks, it does so based on its current size, which is a characteristic of exponential decay. Option C talks about a yearly pay increase of 3% each year, and Option D describes a savings account growing by 3% each year; both are examples of exponential growth. Therefore, the answer is Option B, a one-time bonus of 10% of a worker’s annual salary, as it does not describe a situation where the growth rate is applied over time to an ever-changing base amount.
Given that f (x) = x^2 - 5x + 6, evaluate the function f (-2).
Answer:
f(- 2) = 20
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = (- 2)² - 5(- 2) + 6 = 4 + 10 + 6 = 20
The value of the function f(x) = x² - 5x + 6 at x = -2 is 20 after plugging the value of x is -2 in the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = x² - 5x + 6
Plug x = -2
f(-2) = (-2)² - 5(-2) + 6
f(-2) = 4 + 10 + 6
f(-2) = 20
Thus, the value of the function f(x) = x² - 5x + 6 at x = -2 is 20 after plugging the value of x is -2 in the function.

It takes Lisa 8 1/4 hours to give to her aunts house and takes Lisa 5 3/4 hours to get to her uncle's house how much farther does Lisa have to drive to get to her aunt's house in her uncle's house
Answer:
if she drove away she would have to drive 14 hours, or if it were i the same direction she would have to drive 2 1/2 hours
Step-by-step explanation:
8 1/4 + 5 3/4 = 14
8 1/4 - 5 3/4 = 2 1/2
Lisa has to drive an extra 2 1/2 hours to get to her aunt's house compared to her uncle's house. This is determined by converting the mixed numbers to improper fractions, subtracting the smaller fraction from the larger one, and simplifying the result.
Explanation:The subject of this question falls under Mathematics, specifically subtraction of fractions. In this question, Lisa takes 8 1/4 hours to get to her aunt's house and 5 3/4 hours to get to her uncle's house. The time difference is the extra distance she must travel to reach her aunt's house compared to her uncle's house.
First, we will convert mixed fractions to improper fractions. 8 1/4 becomes 33/4 and 5 3/4 becomes 23/4.Next, subtract the smaller fraction from the larger one: 33/4 - 23/4 = 10/4.Finally, simplify the resulting fraction to obtain the solution. 10/4 simplifies to 2 1/2.So, Lisa has to drive for an extra 2 1/2 hours to get to her aunt's house as compared to her uncle's house.
