Actual distance between two places is 130 miles. The scale of the map is
1 in:100 miles. What is the distance between these two places in the map?
Answers
Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
x inches = 130 miles
Solving for x
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
\(\frac{100}{1}\) = \(\frac{130}{x}\)
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100x = 130
4. Divide each side by 100 to isolate the variable.
x = 1.3
In circle H with m/GHJ = 66 and GH = 10 units, find the length of arc GJ.
Round to the nearest hundredth.
G
H
Answers
Answer: GJ is 2.89 units.
Step-by-step explanation:
J
We use the formula for the length of an arc of a circle:
Length of arc = (central angle/360 degrees) x 2πr
In this case, the central angle is m/GHJ = 66 degrees, and the radius of the circle is half the diameter GH = 5 units.
So,
Length of arc GJ = (66/360) x 2π(5)
Length of arc GJ = (11/60)π(5)
Length of arc GJ ≈ 2.89 units
Rounded to the nearest hundredth, the length of arc GJ is 2.89 units.

Integrate by hand the following functions: adr b) (42³-2r+7) dz Upload Choose a File
Answers
The integral of (42³ - 2r + 7) dz is equal to (42³ - 2r + 7)z + C.
To integrate the function (42³ - 2r + 7) dz, we treat r as a constant and integrate with respect to z. The integral of a constant with respect to z is simply the constant multiplied by z:
∫ (42³ - 2r + 7) dz = (42³ - 2r + 7)z + C
where C is the constant of integration.
Note: The integral of a constant term (such as 7) with respect to any variable is simply the constant multiplied by the variable. In this case, the variable is z.

She is incorrect; the histogram is skewed to the left because there is more data on the right side. She is incorrect; the histogram is symmetrical because the right side is equal to the left side. She is correct; the histogram is skewed to the right because there is less data on the right side.

Step-by-step explanation:
I just did it on edge
Option D is correct. She is correct; the histogram is skewed to the right because there is fewer data on the right side.
How can you spot a skewed graph?
A skewed distribution is one in which one of the two sides is biased (either left or right). It's like a mountain tilting to one side (left or right).
Like the picture, a left skewed graph has an extended tail on the left side of the main peak. A right skewed graph features an extended tail on the right side of the main peak.
She is correct; the histogram is skewed to the right because there is fewer data on the right side.
Hence, option D is correct.

A movie theater sells two sizes ofpopcorn. How much more doesthe box hold than the cone?
Answers
Given the box of popcorns and the cone of popcorns, you can assume that the box is a rectangular prism.
You can use this formula to calculate the volume of the box:
\(V_{r.prism}=lwh\)Where "l" is the length, "w" is the width, and "h" is the height.
In this case:
\(\begin{gathered} l=5\text{ }in \\ w=3\text{ }in \\ h=6\text{ }in \end{gathered}\)Using the formula, you get:
\(V_{r.prism}=V_{box}=(5\text{ }in)(3\text{ }in)(6\text{ }in)=90\text{ }in^3\)Use this formula to calculate the volume of the cone:
\(V_{cone}=\frac{\pi r^2h}{3}\)Where "r" is the radius and "h" is the height.
In this case (knowing that the radius is half the diameter):
\(\begin{gathered} r=\frac{6\text{ }in}{2}=3\text{ }in \\ \\ h=8\text{ }in \\ \\ \pi\approx3.14 \end{gathered}\)Then, you get:
\(V_{cone}=\frac{(3.14)(3in)^2(8in)}{3}\approx75.36\text{ }in^3\)Subtract the volume of the cone from the volume of the box, in order to determine how much more the box holds than the cone:
\(90\text{ }in^3-75.36\text{ }in^3=14.64\text{ }in^3\)Hence, the answer is:
\(14.64\text{ }in^3\)1:12 p.m to 8:11 p.m

What is the code in python to remove ' at the beginning and at the end and also remove the item at index 12?
Answers
To remove the single quotation marks ('') at the beginning and end of a string and remove the item at index 12, you can use Python's string manipulation methods and list slicing. First, you can use the strip() method to remove the surrounding single quotation marks. Then, you can convert the string into a list using the list() function, remove the item at index 12 using list slicing, and finally convert the list back into a string using the join() method.
To remove the single quotation marks at the beginning and end of a string, you can use the strip() method. This method removes any leading and trailing characters specified in the argument. In this case, you can pass the single quotation mark ('') as the argument to strip().
Here's an example:
string = "'example string'"
stripped_string = string.strip("'")
After executing this code, the value of stripped_string will be 'example string' without the surrounding single quotation marks.
To remove the item at index 12 from the string, you need to convert it into a list. You can use the list() function for this conversion. Then, you can use list slicing to remove the item at index 12 by excluding it from the list. Finally, you can convert the modified list back into a string using the join() method.
Here's an example:
string_list = list(stripped_string)
string_list.pop(12)
result_string = ''.join(string_list)
After executing this code, the value of result_string will be the modified string with the item at index 12 removed.

Complete the description of the piecewise function graphed below.
Answers
Step-by-step explanation:
not everything is visible, and the points' coordinates have to optically estimated (particularly for the leftmost point).
I assume, we have the following points :
(-6, 1.5) (-3, 3)
(-3, 2) (1, 2)
(1, 1) (6, -9)
all 3 segments are lines with the basic function definition
y = ax + b
a is the slope of the line function and is always the factor of x.
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point on the line to another.
b is the y-intercept (the y value when x = 0).
the first segment goes from (-6, 1.5) to (-3, 3).
x changes by +3 units (from -6 to -3).
y changes by +1.5 or 3/2 units (from 1.5 to 3).
the slope of the line is 3/2 / 3 = 3/(2×3) = 1/2
giving us the first part
y = (1/2)x + b
b we get by using the coordinates of one point (e.g. -3, 3) as x and y values and solve for b :
3 = (1/2)×-3 + b
3 = -3/2 + b
6/2 + 3/2 = b
9/2 = b
the full equation is
y = (1/2)x + 9/2 = (x + 9)/2
the second segment is a flat, horizontal line and is simply
y = 2
the third segment goes from (1, 1) to (6, -9) :
x changes by +5 units (from 1 to 6).
y changes by -10 units (from 1 to -9).
the slope of the line is -10/5 = -2
giving us the first part
y = -2x + b
b we get by using the coordinates of one point (e.g. 1, 1) as x and y values and solve for b :
1 = -2×1 + b
1 = -2 + b
3 = b
the full equation is
y = -2x + 3

You roll two number cubes.
Let event A = You roll an even number on the first cube.
Let event B= You roll a 4 on the second cube.
Are the events independent or dependent? Why?
OA. Dependent, because 4 is an even number.
OB. Independent, because they have no outcomes in common.
OC. Dependent, because both cubes have six sides.
OD. Independent, because the outcome of the first roll doesn't affect
the outcome of the second roll.
Answers
Answer: D. Independent, because the outcome of the first roll doesn't affect the outcome of the second roll.
Step-by-step explanation: The events are independent, because the outcome of the first roll doesn't affect the outcome of the second roll. The fact that 4 is an even number does not make the events dependent.

in abc, angle a = 90 and an is the altitude. if ab = 20 and AC = 15, find BC, BN, NC, AN
Answers
The missing values are:
BC = 25, BN = 16, NC = 9, and AN = 12
Given:
AB = 20
AC = 15
Using the Pythagorean theorem in triangle ABC:
CB = √AC² + AB²
CB= √20² + 15²
CB= √625
CB= 25
Since, AN is altitude we have ΔNBA~ΔABC and ΔNAC~ΔABC
BN / AN = BA / CB
BN/ 20= 20/25
BN = 16
and, AN / BA = AC / CB
AN /20 = 15/ 25
AN = 12
Now, CN= CB - BN
CN = 25- 16
CN= 9
BC^2 = 20^2 + 15^2
BC^2 = 400 + 225
Since ΔANC is a right triangle so
AN = √15²-12²
AN = √81
AN = 9

Factor out the greatest common factor (GCF) from 6x^4 + 8x^3
Answers
Required factor form is 2x³(3x + 4).
What is GCF?
GCF stands for Greatest Common Factor, also known as the Greatest Common Divisor (GCD). In mathematics, the GCF of two or more numbers is the largest positive integer that divides each of the numbers without a remainder. For example, the GCF of 12 and 18 is 6 because 6 is the largest integer that divides both 12 and 18 without a remainder. The concept of GCF is important in many areas of mathematics, including algebra, number theory, and calculus, and is used in various problem-solving applications.
Given form is 6x⁴+8x³.
Here is two term 6x⁴ and 8x³.
By factorisation,
6x⁴ = 2×3×x⁴ and 8x³ = 2×2×2×x³
The greatest common factor (GCF) of 6x⁴ and 8x³ is 2x³.
To factor it out, we can divide each term by 2x³:
Now,
6x⁴ ÷ 2x³ = 3x
8x³ ÷ 2x³ = 4
So, we can write:
6x⁴ + 8x³ = 2x³(3x + 4)
Therefore, the factored form of 6x⁴ + 8x³ is 2x³(3x + 4).
