Answers
Answer: 6 inch
Step-by-step explanation:
From the question, we are informed that a map of Rockbridge County has a scale factor of 2.5 in = 5 miles.
When the actual distance from Fairfield to Lexington is 12 miles, the distance on the map will be:
= 12/5 × 2.5
= 2.4 × 2.5
= 6 inch

Answer:
[tex]\boxed{\sf{y=-5x+8}}[/tex]Step-by-step explanation:
You can solve this problem using the slope formula and slope-intercept formula.
Slope formula:
[tex]\Longrightarrow: \sf{m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
Slope-intercept formula:
[tex]\Longrightarrow: \sf{y=mx+b}[/tex]
M: represents the slope.B: represents the y-intercept.(1,3) and (2,-2)
y2=(-2)
y1=3
x2=2
x1=1
Rewrite the problem.
[tex]\sf{\dfrac{-2-3}{2-1}=\dfrac{-5}{1}=-5 }[/tex]
The slope is -5.y-intercept is 8.Rewrite the problem.
y=-5x+8
Therefore, the correct answer is y=-5x+8.I hope this helps you! Let me know if my answer is wrong or not.

with m = -5 and point (7,9)?
y - 7 = 9(x - 5)
y - 7 = 5(x - 9)
y - 5 = 7(x - 9)
y - 9= -5(x - 7)
Answers
Answer:
y - 7 = 9(x - 5)
Step-by-step explanation:
Answer:
The answer is y - 9= -5(x - 7)
Step-by-step explanation:

y= mx+b
9= -5(7)+b
9 = -35+b
+35 +35
44=b
So the point slope is y=-5x+44
y - 9= -5(x - 7)
y-9=-5x+35

What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
In the given triangles ABC and CDE,
∠A=∠E and side AB = DE
By vertically opposite angle property,
∠ACB = ∠DCE
Therefore, in triangles ABC and CDE, two angles are equal, and one side is equal.
By Angle-Angle-Side property, both the triangles are congruent.

Which statements regarding the diagram Triangle EBC are true? Select three options
•Angle BEC is an exterior angle
•Angle DEC is an exterior angle
•Angle ABE and EBC are supplementary angles
•Angle BCF and DEC are supplementary angles
•Angle BEC us a remote interior angle to exterior angle BCF
Answers
Triangle EBC have interior angles and exterior angles. The three appropriate options to the given question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
An exterior angle is one that lies outside a given figure. Thus, it is not an interior angle of the figure. While an interior angle is an angle within the boundaries of the figure.
Supplementary angles are two or more angles whose measures add up to the value of angle on a straight line (i.e [tex]180^{o}[/tex]).
Thus considering the given triangle EBC, the appropriate options to the question are:
B. Angle DEC is an exterior angle
C. Angle ABE and EBC are supplementary angles
E. Angle BEC is a remote interior angle to exterior angle BCF
These three options best describes the relationships among the angles of the triangle.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inches.
Usen 3.14
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work. (10 points)
Answers
Answer: See explanation
Step-by-step explanation:
Diameter = 8 inches
Radius = Diameter/2 = 8/2 = 4 inches
Height of the cylinder = 3 inches
Height of the cone = 18 inches
Volume of a cylinder = π r² h
= 3.14 × 4² × 3
= 3.14 × 16 × 3
= 150.72
Volume of a cone = 1/3 π r² h
= 1/3 × 3.14 × 4² × 18
= 1/3 × 3.14 × 16 × 18
= 301.44
From the answer gotten, we can deduce that the volume of the cone is twice the volume of the cylinder.

Answers
Answer:
8.75 +/- 0.657
Step-by-step explanation:
The 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617
What is confidence interval?A confidence interval is a range around a measurement that conveys how precise the measurement is.
Given that, The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours, the confidence level value is 90%
confidence interval = x ± z·s/√n
= 8.75±1.645·1.5/√16
= 8.75±0.617
Hence, the 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617
