The empire state building stands at a height of 1,454 feet. Given the choice between feet feet per second or miles per hour, which rate of measure is more reasonable to describe the speed of a penny when dropped off the top of the building? Justify your reasoning using mathematical laguage
Answers
Answer:
miles per hour
Step-by-step explanation:
speed can be define as the rate of distance covered in a given time.
i.e speed = [tex]\frac{distance}{time}[/tex]
Given that the height (distance) of the empire state building = 1454 feet.
a. For feet per second;
distance = 1454 feet
time = 1 second
speed = [tex]\frac{1454}{1}[/tex]
= 1454 feet/second
b. For miles per hour,
1 feet = 0.000189394 mile
Thus, 1454 feet = 0.2753788 mile
distance = 0.2753788 mile
time = 1 hour
speed = [tex]\frac{0.2753788}{1}[/tex]
= 0.2753788 miles/hour
Comparing the two units of measurement, miles per hour is more reasonable. This is because the penny can not move at that very high speed to hit the ground within 1 second when dropped.
Which of the following combinations would result in multiple triangles? SHOW WORK
A: 45 degrees, 82 degrees, 53 degrees
B: 5 degrees, 122 degrees, 61 degrees
C: 2 cm, 8 cm, 10 cm
D: 10 in, 20 in, 75 degrees
Answers
Multiple triangles would be formed by the combination of 2 cm, 8 cm, and 10 cm.
To have a triangle, three sides of a polygon must be present. Additionally, each side must be less than the total of the other two sides added together to form a triangle.
Consider the following choices as a result:
A: 45 degrees, 82 degrees, 53 degrees.
We don't know the size of the triangle's sides, thus we can't say if it's going to create multiple triangles
.B: 5 degrees, 122 degrees, 61 degrees
This set of degrees won't result in a triangle because the angles add up to 188 degrees, which is greater than 180 degrees, the sum of the interior angles of a triangle.
C: 2 cm, 8 cm, 10 cm
The sum of 2 cm + 8 cm = 10 cm.
As a result, it is impossible for a triangle to be formed since 2 + 8 < 10.D: 10 in, 20 in, 75 degreesTwo sides of the triangle are known, however the angle between them is unknown, therefore it is impossible to tell if multiple triangles will form.
Option C is the only choice that would result in multiple triangles. The side lengths of a triangle are 2 cm, 8 cm, and 10 cm. It is impossible to form a triangle with 2 cm and 8 cm because they are too short to form a triangle, however if you switch the values and compare 8 cm and 10 cm, a triangle is formed.

what is the largest digit to be placed on the blank in the 5 _,310 to make it divisible by 6?
Answers
Answer:
The largest digit to be placed on the blank in the 5_,310 to make it divisible by 6 is 9 to give 59,310
Step-by-step explanation:
The given question requires the digit to be placed in the space left blank in 5_,310 to make it divisible by 6
To answer the question, we note that given that 51,000, 54,000, 57,000, and 60,000 are divisible by 6, and that 310 is not divisible by 6, we have
1,310 is not divisible by 6, but 2,310 is divisible by 6
Therefore, the complete number will be 57,000 + 2,310 = 59,310 which gives;
59310/6 = 9,885
Therefore, the complete number is 59,310, and the required digit is 9.
Solve for v. 23= -81-7+2v
Answers
Answer:
v = 55.5
Step-by-step explanation:
23 = -81 - 7 + 2v
23 = -88 + 2v
23 + 88 = -88 + 88 + 2v
111 = 0 + 2v
111 = 2v
111 ÷ 2 = 2v ÷ 2
55.5 = 1v
55.5 = v
Answer:
v = 55.5
Step-by-step explanation:
23 = -81 - 7 + 2v
1. Simplify by combining like terms
23 = -88 + 2v
2. Isolate the variable by adding 88 to both sides
23 + 88 = -88+ 88 +2v
23 + 88 = 2v
3. Combine like terms
111 = 2v
4. Solve for v by dividing both sides by 2
111/2 = 2v/2
55.5 = v

Answers
Based on the given data, we can calculate the control limits using 3-sigma for the diameter of the auto pistons.
a) The value of x is 155.56 mm (rounded to two decimal places).
b) The value of R is 4.44 mm (rounded to two decimal places).
c) Using 3-sigma, the Upper Control Limit (UCL) for the diameter is calculated as:
UCL = x + 3R = 155.56 + 34.44 = 156.93 mm (rounded to two decimal places)
The Lower Control Limit (LCL) for the diameter is calculated as:
LCL = x - 3R = 155.56 - 34.44 = 154.19 mm (rounded to two decimal places)
d) Using 3-sigma, the Upper Control Limit for the Range (UCLR) is calculated as:
UCLR = D4 * R = 2.115 * 4.44 = 7.89 mm (rounded to two decimal places)
The Lower Control Limit for the Range (LCLR) is always 0 in this case since negative ranges are not possible.
e) If the true diameter mean should be 155 mm, the new centerline (nominal line) would be 155 mm. In this case, the UCL and LCL would be calculated using 3-sigma as follows:
UCL = Nominal + 3R = 155 + 34.44 = 156.37 mm (rounded to two decimal places)
LCL = Nominal - 3R = 155 - 34.44 = 153.63 mm (rounded to two decimal places)
Please note that the control limits calculated using 3-sigma assume a normal distribution and the data follows the same pattern in the future.

Answers
75th Percentile = 45 means that 75% of the observations are values less than or equal to 45.
To calculate the 75th percentile, we arrange the observations in ascending order and find the value at which 75% of the data falls below. In this case, the 75th percentile is 45, indicating that 75% of the observations have values less than or equal to 45.
In other words, if we have a dataset with 100 observations, the 75th percentile value would be the value that separates the top 25% (from observation 76 to 100) from the bottom 75% (from observation 1 to 75), and that value is 45.
the statement "75th Percentile = 45" means that 75% of the observations in the dataset have values less than or equal to 45.

a cylindrical brass pipe is 600 cm in length. its outside diameter is 10 cm, and its inside radius is 4 cm. what is the total surface area of this pipe (including the internal surface area of this pipe)?
Answers
The total surface area of the cylindrical brass pipe, including the internal surface area, is [tex]10841π cm^2[/tex], where π is approximately 3.14159.
To calculate the total surface area of the cylindrical brass pipe, we need to consider both the external and internal surface areas.
The external surface area of a cylinder is given by the formula:
A_external =[tex]2πrh + πr^2[/tex]
Where:
r is the radius of the outer surface (half of the outside diameter), which is 10 cm / 2 = 5 cm
h is the height of the cylinder, which is given as 600 cm
Plugging in the values:
A_external = [tex]2π(5 cm)(600 cm) + π(5 cm)^2[/tex]
= [tex]2π(3000 cm^2) + π(25 cm^2)[/tex]
= [tex]6000π cm^2 + 25π cm^2[/tex]
= [tex]6025π cm^2[/tex]
The internal surface area of a cylinder is given by the formula:
A_internal = [tex]2πrh + πr^2[/tex]
Where:
r is the radius of the inner surface (inside radius), which is given as 4 cm
h is the height of the cylinder, which is given as 600 cm
Plugging in the values:
A_internal = [tex]2π(4 cm)(600 cm) + π(4 cm)^2[/tex]
= [tex]2π(2400 cm^2) + π(16 cm^2)[/tex]
= [tex]4800π cm^2 + 16π cm^2[/tex]
= [tex]4816π cm^2[/tex]
To find the total surface area, we add the external and internal surface areas:
Total surface area = A_external + A_internal
= [tex]6025π cm^2 + 4816π cm^2[/tex]
= [tex]10841π cm^2[/tex]
Therefore, the total surface area of the cylindrical brass pipe, including the internal surface area, is [tex]10841π cm^2[/tex], where π is approximately 3.14159.

Which of the following correctly refers to the last element in the array of integers called numbers? O numbers[length of numbers] O numbers[last numbers] O numbers[length of numbers-1] O numbers(size) Question 5 Once an array is created, it cannot be resized during program execution. O True O False
Answers
The following correctly refers to the last element in the array of integers called numbers:
numbers[length of numbers-1].
An array is a collection of items, which can be of the same type and stored in contiguous memory. Once an array is created, its size cannot be altered during program execution. The last element in an array of integers called numbers can be referred to using numbers[length of numbers-1]. This is because array indexing starts from zero and the length of an array is the number of elements it contains, but indexing ends at length-1. Therefore, the last element in an array is always at the index length-1.It is important to note that array indexing is an error-prone area of programming, and one should always ensure that indices do not go out of bounds. This can lead to memory access violations and undefined behavior. A good practice is to use loops that start from 0 and end at length-1 when iterating over an array, to ensure that all elements are processed. It is also advisable to use constants or symbolic names to represent array indices, to make the code more readable and easier to maintain.
In summary, an array is a collection of items that can be stored in contiguous memory and cannot be resized during program execution. The last element in an array of integers called numbers can be referred to using numbers[length of numbers-1]. Array indexing is an error-prone area of programming, and one should always ensure that indices do not go out of bounds.

neptune is an average distance of 4.5×109km from the sun. estimate the length
Answers
We are to estimate the length of the Neptune which has an average distance of 4.5 × 10^9 km from the sun. The length of Neptune can be estimated using the circumference of its orbit.
We are given that Neptune is an average distance of 4.5 × 10^9 km from the sun. To estimate the length of Neptune, we can use the circumference of its orbit. The circumference of Neptune's orbit can be estimated using the formula;
Circumference (C) = 2πr
Where C is the circumference, r is the radius and π is a mathematical constant equal to 3.14.
Since we are given the average distance of Neptune from the sun, we can estimate the length of Neptune using the above formula.Substituting the values given into the formula;
Circumference (C) = 2πr = 2 × 3.14 × 4.5 × 10^9 kmC = 28.26 × 10^9 km
Hence, the circumference of Neptune's orbit is approximately 28.26 × 10^9 km. Since the circumference of a circle is equal to 2πr, we can estimate the radius of the orbit by dividing the circumference by 2π;
r = C / 2π = (28.26 × 10^9 km) / (2 × 3.14) = 4.50 × 10^9 km
Hence, the radius of Neptune's orbit is approximately 4.50 × 10^9 km.
Since Neptune's orbit is almost circular, its length can be estimated using the formula;
Length = 2πrLength = 2 × 3.14 × 4.5 × 10^9 kmLength = 28.26 × 10^9 km
Hence, the length of Neptune is approximately 28.26 × 10^9 km.
Therefore, we can estimate the length of Neptune using the circumference of its orbit which is approximately 28.26 × 10^9 km.
