Step-by-step explanation:
The scale of a map is 0.5 inches :10 km. Find the actual distance corresponding to the map distance of 10 inches.
Answer:
200 km
Step-by-step explanation:
Create a proportion where x is the actual distance:
[tex]\frac{0.5}{10}[/tex] = [tex]\frac{10}{x}[/tex]
Cross multiply and solve for x:
0.5x = 100
x = 200
So, the actual distance is 200 km
Which function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis?
Answer:
g(x)=-8(3^x)
Step-by-step explanation:
Given: f(x)=3^x
Multiply by 8: f(x)=8(3^x)
Negate function: g(x)=-8(3^x)
The function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).
What is an exponential function?It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x.where a is a constant and a>1
It is given that, the function represents the exponential function f(x) = 3x.
We have to find the function after a vertical stretch by a factor of 8 and a reflection across the x-axis.
We have to do geometric transformation, It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
Thus, the function represents the exponential function f(x) = 3x after a vertical stretch by a factor of 8 and a reflection across the x-axis will be g(x)=-8(3ˣ).

Match the graph with its equation.
A. –6x – 2y = 12
B. –6x + 2y = 12
C. 6x + 6y = 12
D. 6x + 2y = 12
Answer:
The answer is A. -6x-2y=12.
Step-by-step explanation:
In order to graph the equation, start by rewriting the equation in slope-intercept form. To rewrite the equation in slope-intercept form, add 6x to both sides of the equation, and then divide each term by -2 and simplify. Now, the equation should look like y= -6-3x.
Using the slope-intercept form, you can find the slope and y-intercept. By using the formula of y= mx+b, m= -3 and b= -6. Thus, the slope is -3 and the y-intercept is (0,-6).
Now, you can create a table of x and y values to graph the equation. After graphing the table of x and y values, the final answer is -6x-2y=12.

Answer:
The probability of her not choosing yellow is 6/22.
Step-by-step explanation:
The probability that she chooses a blue skittle is 6/23 since she eats one blue skittle the total decreases to 22. So the probability of her not choosing yellow is 6/22

Write a formula for the given measure. Let P represent the perimeter in inches, and w represent the width in inches. Identify which variable depends on which in the formula.
Complete Question:
Write a formula for the given measure. Let P represent the perimeter in inches, and w
represent the width in inches. Identify which variable depends on which in the formula.
*The perimeter of a rectangle with a length of 5 inches
Answer:
P = 2(5 + w)
Or
P = 20 + 2w
P is the dependent variable
w is the independent variable
P depends on w.
Step-by-step explanation:
Given:
Perimeter of rectangle = P
Width of the rectangle = w
Length of the rectangle = l = 5 in.
Formula for perimeter of a rectangle = 2(length + width)
Plug in the values. Formula for the given measure would be:
P = 2(5 + w)
Or
P = 20 + 2w
P is the independent variable, while w is the dependent variable.
This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,
P depends on w.

This cone and sphere have equal volumes.
What is the radius of the sphere?
Answer:
the radius of the sphere is 12 cm.
Step-by-step explanation:
IN A CONE
vertical height (h) = 27 cm
radius (r) = 32 / 2 = 16 cm
Now the volume of cone is
= 1/3 *h*π*r²
= 1/3 * 27 *π *16²
= 2304π cm³
Also by the question the cone and the sphere have equal volumes so
volume of sphere = volume of cone
= 2304 π cm³
OR, 4/3 πr³ = 2304 π
4/3 * r³ = 2304
r³ = 2304 * 3 / 4
r³ = 1728
r = ∛1728
r = 12 cm

For an art project, Kelvin cut a 4-foot piece of yarn into pieces. He then measured the length of each piece of yarn to the nearest inch. He wants to summarize the data using a histogram. Which units are the best to use to label the x- and y-axes
A
label the x-axis "Length (feet)," and label the y-axis "Pieces of Yarn"
B
label the x-axis "Pieces of Yarn," and label the y-axis "Length (feet)"
C
label the x-axis "Length (inches)," and label the y-axis "Pieces of Yarn"
D
label the x-axis "Pieces of Yarn," and label the y-axis "Length (inches)"
Answer:
I think answers is
D
label the x-axis "Pieces of Yarn," and label the y-axis "Length (inches
The best units to label is C. label the x axis "Length (inches)," and y axis "Pieces of Yarn".
What is Histogram?A histogram is defined as the pictorial representation of data in the form of a bar graph where the X axis represents the columns of classes and Y axis represents the frequency of those classes.
Given that,
Kelvin cut a 4-foot piece of yarn into pieces.
There may be many pieces of yarns.
He measured the length of each piece of yarn to the nearest inch.
Total length of the yarn = 4 foot = 4 × 12 inches = 48 inches
x axis contains the interval range of the length of the pieces in inches.
This length can be divided in to intervals of length 4.
y axis contains the number of pieces of yarn falling in to that interval.
Hence the correct option is C.
