There are 120 people on the bus 50% get off at the first stop 20% get off at the second stop. The rest get off on the third stop. How many people got off the bus at the third stop? Please show the correct answer :)
Answer:
48 people
Step-by-step explanation:
First, find how many were left after the first stop:
120(0.5)
= 60
Find how many were left after the second stop:
60(0.8)
= 48
So, since the rest got off on the third stop, this means 48 people got off on the third stop.
Step-by-step explanation:
(saw this trick on tik tok)
50%+20%= 70%
100%-70%= 30%
30% of 120 people

Which is an x-intercept of the graph of the function Y = Cot(3x)?
Answer:
A on ed 2021
Step-by-step explanation:
if you go on Desmos graphing calculator and graph y = cot(3x)
then graph the points
A. (pi/6, 0)
B. (pi/3, 0)
C. (3pi, 0)
D. (6pi, 0)
POINT A. (pi/6, 0) is the only point that intercepts the graph
The x-intercept of the graph of the function y = cot(3x) is ,
⇒ (π/6, 0)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Here, The graph of the function is given as:
y = cot(3x)
Now, To determine the x-intercept of the graph, we set the graph to 0.
So, we have:
cot(3x) = 0
Take the arccot of both sides;
3x = arccot(0)
Evaluate the arccot of 0
3x = π/2
Divide both sides by 3
x = π/6
Hence, the x-intercept of the graph of the function y = cot(3x) is
⇒ (π/6, 0)

The writers for a TV show have determined that they need to add a new character. One demographic wants the new character to be a man, or someone who can do martial arts. Another demographic wants the new character to be a woman, or someone who is a medical doctor. The writers want to please both demographics. Therefore, the new character will be someone who can do martial arts or is a medical doctor.
Which rule of inference was used here?
A. Conjunction
B. Resolution
C. Modus Ponens
D. Disjunctive Syllogism
E. Hypothetical Syllogism
F. Addition
G. Modus Tollens
H. Simplification
Answer: Resolution
Step-by-step explanation:
The rule of inference that was used here is Resolution. We should note that the resolution principle is used to know whether an argument is valid or not and hence make conclusion.
Resolution typically complements the sentences given such that the new clause has every information given and satisfies everyone.
We can see that from the question, one demographic wants the new character to be a man, or someone who can do martial arts while the other demographic wants a woman,or a medical doctor. Eventually, the writers want to please both demographics and said that the new character will be a martial artsmist or a medical doctor.

In triangle ABC, m
hypotenuse: AB, BC, or CA?
Answer:
The hypotenuse is the side AB
Step-by-step explanation:
Right Triangles
Right triangles are identified because they have an internal angle of 90°. The longest side is the hypotenuse and the two smaller sides are called the legs.
The hypotenuse is always opposite to the right angle.
The image provided below shows a right triangle ABC, whose angle C is 90°. Thus, the hypotenuse is the side AB.

Find the perimeter of the following figure.
A. 21 inches
B. 25 inches
C. 33 inches
D. 38 inches
Step-by-step explanation:
Notice that the perimeter of the figure is equal to the perimeter of a rectangle that is 6in by (5in + 8in).
Hence the perimeter
= 2(6in + 5in + 8in)
= 2 * 19in = 38 inches. (D)
slope is 2 and contains the point (5,-7)
write the equation of a line
Answer:
y = 2x - 17
Step-by-step explanation:
y = mx + b
m = 2
y = 2x + b
Plug in (5, -7) for x & y.
-7 = 2(5) + b
-7 = 10 + b
Subtract 10 from both sides.
-17 = b
y = 2x - 17
Check work.
-7 = 2(5) - 17
-7 = 10 - 17
- 7 = -7
Your answer is correct.
I. A rhombus is a special type of square. II. A rectangle is a special type of rhombus. III. A trapezoid is a special type of parallelogram. Which of the above statements are true? i only iii only iii only None of the above statements are true.
Answer: I. only
--------------------------------------------------------------------------------------------------------------
Explanation :
II. False. a rectangle is a special type of rhombus since a rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.
I. True. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.
III. False. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.

Suppose y varies directly with x. Write a direct variation equation that relates x and y when y = 6 and x = 12
Answer:
y = 1/2x
Step-by-step explanation:
y = 6
x = 12
y = ax
6 = a(12)
