Answer:
A. 2x-13
Step-by-step explanation:
5x + 8 = 2x + 14
Need a little bit of help would be thankful xxx
Answer: x = 2
Step-by-step explanation: 5x + 8 = 2x + 14
5x + 8 - 2x = 2x + 14 - 2x
3x + 8 - 8 = 14 - 8
3x = 6
3x/3 = 6/3
x = 2
For this problem, x would equal 2.

100 nautical miles equals about 185 km to the nearest kilometer how far in kilometers is 140 nautical miles.
Answer:
100 nmiles = 185 km
1 km = 100 n miles / 185
0.541 n miles / 1 km
140 n miles / 0.541 n mile / km = 259 km

find each angle measure in the regular polygon
a. 144°
b. 135°
c. 180°
d. 140°
=====================================================
Work Shown:
E = exterior angle
n = number of sides
For any regular polygon, E = 360/n.
In this case, n = 10 as there are 10 sides, so E = 360/n = 360/10 = 36 degrees is the measure of each exterior angle.
Each interior angle is 180-E = 180-36 = 144 degrees
--------------
An alternative is to plug n = 10 into the formula below to get the measure of each interior angle i
i = 180(n-2)/n
i = 180(10-2)/10
i = 180(8)/10
i = 1440/10
i = 144
note: S = 180(n-2) is the sum of all the interior angles of any convex polygon. Dividing this sum over n will evenly divide the angle total to each interior angle.

Answer:
Lines in the same plane that intersect to form a 90 degree angle
Step-by-step explanation:
Final answer:
Parallel lines in Euclidean geometry are lines in the same plane that never intersect, maintaining a consistent distance from each other. The parallel postulate ensures the uniqueness of parallel lines through a given point relative to a line.
Explanation:
Parallel lines are defined as lines in the same plane that never intersect no matter how far they are extended in either direction. This concept is a fundamental part of Euclidean geometry, and it is also important in understanding the basis of linear perspective, where parallel lines appear to converge as they recede into the distance.
Moreover, while discussing the relationship between planes and lines, if three nonparallel planes are considered, they typically intersect in a single unique point or along a single line, depending on their orientation and equations. In contrast, parallel lines would not provide such a point or line of intersection since they never meet.

A cereal box is 12cm tall. The area of the base is 7cm. What is the volume?
Answer:
84cm3
Step-by-step explanation:
Volume of the box = Area x Height
V = AH
From the question given,
Height = 12cm
Area = 7cm2
Volume =?
Volume = Area x Height
Volume = 7 x 12
Volume = 84cm3
Therefore, the volume of the cereal box is 84cm3
The volume of the cereal box is 84 cm³
Volume of solid shapesFrom the question, we are to determine the volume of the cereal box
The volume of the cereal box can be calculated using
Volume = Base area × Height
From the given information
Base area = 7cm²
Height = 12 cm
Then,
Volume of the cereal box = 7cm² × 12cm
Volume of the cereal box = 84 cm³
Hence, the volume of the cereal box is 84 cm³.

If you had 20 equal parts, how would you shade in 20% of it? How much parts would you have shade in?
Answer:
4
Step-by-step explanation:
20 percent is 1/5. 1/5 of 20 is 4.
You would need to shade in 4 parts.
20% of something is equal to 1/5 (because 100/5=20), so you would need to find 1/5 of 20. You can do this by dividing 20 by 5, and 20 ÷ 5 = 4.

Answer:
A. 20°
Step-by-step explanation:
ΔABC's full internal angle measurements = 180°
m∠CAB = 80°
m∠ACB = 50°
m∠DBA = 30°
m∠DBC = ?
Add the measurements of the angles together, and subtract from the total:
m∠DBC = 180 - (80 + 50 + 30)
m∠DBC = 180 - (160)
m∠DBC = 20°
A. 20° is your answer.
~
Answer:
∠DBC = 20°
Step-by-step explanation:
∠A + ∠C + ∠ABC = 180 { sum of all angles of triangle}
50 + 80 + ∠ABC = 180
130 +∠ABC = 180
∠ABC = 180 - 130
∠ABC = 50°
∠ABD + ∠DBC = ∠ABC
30 + ∠DBC = 50
∠DBC = 50 - 30
∠DBC = 20°

A student is selected at random. What is the probability, as a decimal rounded to the nearest
thousandth, that the selected student is going on the field trip given that the student is an eleventh
grader?
Answer:
0.245
Step-by-step explanation:
Probability is the chance or likelihood that an event will occur.
Probability = Expected outcome of event/Total outcome of event
Since we are to find the probability that the selected student is going on the field trip given that the student is an eleventh
grader;
The expected outcome of event will be 13 as located on the table.
Total outcome of event will be the total number of students that went for the field trip.
Total outcome = 12+9+13+19
Total outcome of event = 53
Probability = 13/53
Probability = 0.245(to nearest thousandth)

Substitute the values into the formula: 3. Simplify the right side: 4. Divide 12π to both sides: Step 5 is to . The radius of the cone is . V = 1 3 πr²h 48π = 1 3 πr²(36) 48π = 12πr² 4 = r²
Answer:
C and A
Step-by-step explanation:
Step 5 is to ( C ) take the Square root of both sides
The radius of the cone is ( A ) 2 inches
The radius of the cone is 2 inches.
The volume of cone:The volume of a cone is determined by the amount of space occupied by the cone. A three-dimensional figure having a single circular base is known as a cone. The base and the vertex are connected by a curved surface. A cone with a radius of r has a volume V that is one-third the area of the base B times the height h.
[tex]V=\frac{1}{3} \pi r^{2} h[/tex] or [tex]V=\frac{1}{3} Bh[/tex],
Since, [tex]B=\pi r^{2}[/tex]
How to determine the volume of cone?Given that the volume of cone V is 48π cubic inches and Height of the cone h=36 inches.Volume of cone [tex]V=\frac{1}{3} \pi r^{2} h[/tex] -------1
Here, the base of the cone is circular in shape and the area of circle is [tex]\pi r^{2}[/tex]. Consider [tex]B=\pi r^{2}[/tex]
Substituting the area of base in the equation (1).
[tex]V=\frac{1}{3} \pi r^{2}[/tex]
[tex]= \frac{1}{3} Bh[/tex]
Substitute the given values in the equation (1).
⇒ [tex]48\pi =\frac{1}{3} \pi r^{2} 36[/tex]
⇒ [tex]\frac{48\pi }{36\pi } =\frac{r^{2} }{3}[/tex]
⇒ [tex]\frac{12(3)}{9}=r^{2}[/tex]
⇒[tex]4=r^{2}[/tex]
⇒ [tex]r=2[/tex]
Thus, the radius of the cone is 2 inches.

Which is a factor of x2 - 9x + 14?
X-9
x-2
x + 5
X +7
ANSWER
x-2
b
Answer:
(x - 2)
Step-by-step explanation:
Given
x² - 9x + 14
Consider the factors of the constant term (+ 14) which sum to give the coefficient of the x- term (- 9)
The factors are - 2 and - 7, since
- 2 × - 7 = + 14 and - 2 - 7 = - 9, thus
x² - 9x + 14 = (x - 2)(x - 7) ← in factored form
Thus (x - 2) is a factor of the expression
