Answer:
F(n) = (5n + 3) - (2n - 5)
F(4) = (5*4 + 3) - (2*4 - 5)
= 20 + 3 - 8 + 5
= 20
Hope this helps!

Answer:
20
Step-by-step explanation:

= (5×4+3) - (2×4-5)
= (20+3) - (8-5)
= 23 - 3

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°

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 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)

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.

The volume of a dollhouse is V=24×8×10+1/2 ×24×6×8. Therefore, the correct answer is option A.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, Jasper built a dollhouse for his younger sister.
A rectangular prism has a length of 24 inches, width of 8 inches, and height of 10 inches.
We know that, the formula to find the volume of a rectangular prism is Length×Width×Height
Now, V₁ =24×8×10
= 1920
A triangular prism has a triangular base of 24 inches and height of 6 inches. The height of the prism is 8 inches.
V₂=Area of triangle ×Height
= 1/2 ×24×6×8
= 12×6×8
= 576
So, equation is V=V₁+V₂
V=24×8×10+1/2 ×24×6×8
Therefore, option A is the correct answer.
