Surface area of cone is [tex]18 \pi[/tex] square units
Solution:
Given that cone with a slant height of 7 and a radius of 2
To find: surface area of cone
The surface area of a cone is equal to the curved surface area plus the area of the base
The surface area of cone is given by formula:
[tex]S. A=\pi r^{2}+\pi r l[/tex]
Where "r" is the radius and "l" is the slant height of cone
Substituting r = 2 and l = 7 in above formula,

American Airlines had a flight going out later that day. They charge $53 dollars for each first class ticket, and $21 dollars for each coach ticket. There were 139 passengers total.30% of the passengers composed of the first class. How much money did American Airlines make total?
American airlines made a total money of $ 4263
Solution:
Given that,
Cost of 1 first class ticket = $ 53
Cost of 1 coach ticket = $ 21
There were 139 passengers total
30% of the passengers composed of the first class, Which means 30 % of 139 are first class
Number of first class passengers = 30 % of 139
[tex]\rightarrow \frac{30}{100} \times 139 = 41.7[/tex]
Thus approximately 42 passengers are from first class
Number of coach class passengers = 139 - 42 = 97
So we have,
Number of first class passengers = 42
Number of coach class passengers = 97
To find: Total money made by American airlines
We can frame a equation as:
total money = (Number of first class passengers x Cost of 1 first class ticket) + (Number of coach class passengers x Cost of 1 coach ticket)
[tex]\text{ total money } = 42 \times 53 + 97 \times 21\\\\\text{ total money } = 2226 + 2037 = 4263[/tex]
Thus american airlines made a total money of $ 4263

Your friend wants to borrow $1,137.45 from you to pay off a credit card that charges a 14.7% APR. You agree to the loan but require your friend to pay you interest of 3.6% APR on the loan and your friend agrees.
How much interest does your friend save compared to the credit card at the end of the first month?
Answer:
$10.52
Step-by-step explanation:
(1137.45 x 14.7%) / 12 - (1137.45 x 3.6%) /12 = 10.52
The amount of interest that your friend save compared to the credit card at the end of the first month is $10.5.
InterestFirst step
Interest at 14.7% APR
Interest=(1137.45 x 14.7%) / 12
Interest=$13.9
Interest at 3.6% APR
Interest=(1137.45 x 3.6%) /12
Interest = $3.4
Second step
Interest saved=$13.9-$3.4
Interest saved=$10.5
Therefore the amount of interest that your friend save compared to the credit card at the end of the first month is $10.5.

Which of the following is a true statement?
A. All real numbers are rational numbers
B.All whole numbers are natural numbers
C.All integers are whole numbers
D.All natural numbers are integers
The correct answer is D. All natural numbers are integers, as natural numbers are part of the larger set of integers which includes all whole numbers both positive, negative, and zero.
Explanation:Right Answer to the Student's QuestionOut of the options given, the true statement is: D. All natural numbers are integers. This is because natural numbers include all positive counting numbers from 1 upwards, which are also part of the integers set that includes all whole numbers both positive and negative, as well as zero.
Explanation of Incorrect OptionsOption A is incorrect because not all real numbers are rational. Real numbers include both rational numbers (which can be written as fractions of integers) and irrational numbers (which can't be expressed as fractions of integers).
Option B is incorrect because while all whole numbers are natural numbers, the set of whole numbers also includes 0 which is not considered a natural number.
Option C is incorrect since all integers are indeed whole numbers, but not all whole numbers are integers as integers also include negative numbers.
Concepts DiscussedIn addition to the answer, the commutative property of addition, which states that A+B=B+A was mentioned. This property holds true for the addition of ordinary numbers, such as 2 + 3 is the same as 3 + 2.

PART 1: What is the formula for finding a the midpoint of a segment?
Answer:
I m not an expert in maths but I m sure it is Option D
Final answer:
The midpoint of a segment can be found by averaging the x-coordinates and y-coordinates of the endpoints, with the formula M = ((x₁ + x₂) / 2, (y₁ + y₂) / 2) representing the midpoint's coordinates.
Explanation:
The formula for finding the midpoint of a segment involves calculating the average of the x-coordinates and the average of the y-coordinates of the two endpoints of the segment.
If we have two points, A(x₁, y₁) and B(x₂, y₂), the coordinates of the midpoint M will be calculated as follows:
Mx = (x₁ + x₂) / 2My = (y₁ + y₂) / 2Thus, the coordinates of the midpoint M will be (Mx, My). This formula is essential when dealing with problems involving geometry, coordinate systems, or finding the center point between two given locations on a line segment.

An object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. Which cosine function may be used to model the height of the object?
Answer:
[tex]y=2\text{cos}((\frac{2\pi}{3})t)[/tex]
Step-by-step explanation:
We have been given that an object oscillates 4 feet from its minimum height to its maximum height. The object is back at the maximum height every 3 seconds. We are asked to find the cosine function that can be used to model the height of the object.
We know that standard form of cosine function is [tex]y = A\cdot \text{cos}(Bt-C)+D[/tex], where,
|A| = Amplitude,
Period = [tex]\frac{2\pi}{|B|}[/tex],
C = Phase shift,
D = Vertical shift.
Since distance between maximum and minimum is 4, therefore, amplitude will be half of it, that is, [tex]A = 2[/tex].
Since objects gets back to its maximum value in every 3 seconds, therefore, period of the function is 3 seconds. We know that period is given by [tex]\frac{2\pi}{|B|}[/tex], therefore, we can write [tex]\frac{2\pi}{|B|}=3[/tex], therefore, [tex]B = \frac{2\pi}{3}[/tex].
We haven't been given any information about phase and mid-line, we can assume the values of C and D to be zero .
Therefore, our function required function would be [tex]y=2\text{cos}((\frac{2\pi}{3})t)[/tex].
2. What is the minimum of the sinusoidal function? Please help thank you
Answer: 1
Step-by-step explanation:
It will be the smallest value for f(x).
The minimum of a sinusoidal function is the lowest point on the graph that is 1.
The minimum of a sinusoidal function is the lowest point on the graph. Looking at the image you provided, the minimum point is the lowest y-coordinate the curve reaches.
Since the graph is a sine wave, it oscillates between a maximum and a minimum value. For a standard sine function, which this graph appears to resemble, these extrema occur at points where the sine of the angle is either 1 or -1.
The minimum value of sine is -1, but the actual minimum value of the function on the graph will depend on any vertical shift and amplitude changes.
To find the exact minimum value from the graph, you'd look for the lowest point on the y-axis that the graph reaches. From the image, it's not perfectly clear, but it looks like the minimum value is around -2 on the y-axis.
This would be the case if the function has no vertical shift from the standard sine wave. If there's a vertical shift, the minimum would be the standard minimum value of sine (-1) plus the vertical shift.

Jasmine can decorate 37 cakes every 5 minutes. She works for 7 hours a day. Estimate the total number of cakes she can decorate one day.
Answer:
3108
Step-by-step explanation:
number of 5-min segments in 1 hour
= 1 hour ÷ 5 min
= 60 min ÷ 5 min
= 12
number of 5-min segments in 7 hours
= 12 x 7
= 84
given that during each 5 min segment, jasmine decorates 37 cakes
i.e
1 (5-min) segment -----> decorates 37 cakes
84 (5-min) segments -----> decorates 37 x 84 = 3108 cakes
In this question, we're trying to find how many cakes Jasmine can decorate in 1 day.
We know that she can decorate 37 cakes everyone 5 minutes.
We also know she works 7 hours a day.
First, we need to find how much she makes it an hour.
To find this, multiply 37 by 12.
37 · 12 = 444
This means that she can decorate 444 cakes in an hour.
Now, multiply 444 by 7 to see how much she can decorate in a day.
444 · 7 = 3,108
This means that she can decorate 3,108 cakes in a day.
Answer:
3,108 cakes
write an equation of a line in slope -intercept form thag is parallel to the line 3x-2y=8
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
We have the following equation of the line:
[tex]3x-2y = 8[/tex]
We manipulate algebraically:
[tex]-2y = -3x + 8\\y = \frac {3} {2} x-4[/tex]
Thus, a parallel line will have an equation of the form:
[tex]y = \frac {3} {2} x + b[/tex]
Answer:
[tex]y = \frac {3} {2} x + b[/tex]
write the equation of the line that passes through the point (-1,-6) and is perpendicular to a line that passes through the points (-2,5) and (-4,8)
Answer:
[tex]y=\frac{2}{3}x-\frac{16}{3}[/tex]
Step-by-step explanation:
step 1
Find the slope of the given line
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
(-2,5) and (-4,8)
substitute the values in the formula
[tex]m=\frac{8-5}{-4+2}[/tex]
[tex]m=\frac{3}{-2}[/tex]
[tex]m=-\frac{3}{2}[/tex]
step 2
Find the slope of the perpendicular line to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
so
[tex]m_1*m_2=-1[/tex]
[tex]m_1=-\frac{3}{2}[/tex] ----> slope of the given line
therefore
[tex]m_2=\frac{2}{3}[/tex] ---> slope of the perpendicular line to the given line
step 2
Find the equation of the line in point slope form
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=\frac{2}{3}[/tex]
[tex]point\ (-1,-6)[/tex]
substitute
[tex]y+6=\frac{2}{3}(x+1)[/tex]
step 3
Convert to slope intercept form
[tex]y=mx+b[/tex]
isolate the variable y
[tex]y+6=\frac{2}{3}x+\frac{2}{3}[/tex]
[tex]y=\frac{2}{3}x+\frac{2}{3}-6[/tex]

How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube wide?
Answer:
Part 3) [tex]SA=288\ cm^2[/tex]
Part 4) [tex]64\ cm^2[/tex]
Step-by-step explanation:
Part 3) Calculate the total surface area of three 4 cm cubes
we know that
The surface area of a cube is equal to the area of its six square faces
[tex]SA=6b^2[/tex]
so
The surface area of three cubes is equal to the area of its 18 square faces
[tex]SA=18b^2[/tex]
where
b is the length side of the square face
In this problem
[tex]b=4\ cm[/tex]
so
The surface area of three cubes is
[tex]SA=18b^2[/tex]
substitute the given value
[tex]SA=18(4)^2[/tex]
[tex]SA=288\ cm^2[/tex]
Part 4) How much surface area would be lost if you glued three 4-cm cubes together to make a rod that is three cubes long and one cube wide?
In this case the total surface area of the three glued 4-cm cubes is equal to the area of its 14 square faces
so
The surface area lost is equal to
[tex]18b^2-14b^2=4b^2[/tex]
substitute
[tex]4(4)^2=64\ cm^2[/tex]
Gluing three 4-cm cubes together to form a rod results in a loss of 64 cm²of surface area because the areas of the glued faces are no longer exposed.
Each individual cube has 6 faces, so the surface area of one cube is 6 times the area of one face. With a side length of 4 cm, the area of one face is 4 cm imes 4 cm = 16 cm². Thus, the total surface area for one cube is 6 imes 16 cm²= 96 cm². For three separate cubes, this would be 3 imes 96 cm² = 288 cm².
When the three cubes are glued together side by side to form a rod, they share faces. Each glue contact removes two faces worth of area (one from each cube). As there are two glue contacts, a total of 4 faces are lost. Therefore, the lost surface area is 4 imes 16 cm2 = 64 cm².
The original total surface area was 288 cm², so the new surface area after gluing is 288 cm² - 64 cm² = 224 cm². Hence, gluing the cubes together results in a loss of 64 cm² of surface area.
How do I explain and show the work for a math word problem of If the baby was 8 lbs. 9 oz. and doubled her weight the first six months
Answer:
5 lb 11⅓ oz
Step-by-step explanation:
First, convert the weight at birth from pound and ounces to just ounces.
8 lb × 16 oz/lb + 9 oz = 137 oz
The baby doubles its weight in the first six months. That means its weight increases by 137 oz over 6 months. To find how much weight was gained in 4 months, write a proportion.
137 / 6 = x / 4
6x = 548
x = 91 ⅓
The baby gained 91 ⅓ oz in 4 months, or 5 lb 11⅓ oz.
