A movie ticket cost me $5.60 after a 20% coupon. What was the original price of the ticket?
Answer:
7.00
Step-by-step explanation:
discount = original price *20%
final price = original price - discount
Substituting the equation for discount
final price = original price - original price*20%
Factoring out the original price
final price = original price (1-20%)
Changing to decimal form and putting the final price
5.60 = original price (1-.2)
5.60 = original price (.8)
Divide by each side by .8
5.6/.8 = original price (.8)/.8
7 = original price

How do I tell the difference between sss and sas?
SSS (Side-Side-Side) requires three pairs of equal sides to prove triangle congruence, while SAS (Side-Angle-Side) requires two pairs of equal sides and one pair of equal included angles.
Explanation:In mathematics, specifically in geometry, SSS (Side-Side-Side) and SAS (Side-Angle-Side) are two methods used to determine if two triangles are congruent. Congruent triangles are triangles that have the same size and shape.
SSS (Side-Side-Side)
The SSS criterion states that if all three sides of one triangle are respectively equal in length to all three sides of another triangle, then the two triangles are congruent. You do not need to know any angle measurements.
SAS (Side-Angle-Side)
The SAS criterion states that if two sides and the included angle (the angle between the two sides) of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.
To distinguish between the two, remember that for SSS you're comparing three sides, and for SAS you're comparing two sides and the angle that is between them.

Complete Question
A bag contains red and blue marbles, such that the probability of drawing a blue marble is 3/8. an experiment consists of drawing a marble, replacing it, and drawing another marble. The two draws are independent. A random variable assigns the number of blue marbles to each outcome.
To write the Probabilty mass function, we have to establish that in two draws with replacement, the possible number of blue marbles that can be drawn is 0, 1 and 2.
Probability of drawing a blue marble = P(B) = (3/8)
Probability of not drawing a blue marble = P(B') = 1 - (3/8) = (5/8)
- Probability of drawing 0 blue marbles in 2 draws with replacement = P(B') × P(B') = (5/8) × (5/8) = (25/64) = 0.390625
- Probability of drawing one blue marble in 2 draws with replacement
= [P(B) × P(B')] + [P(B') × P(B)]
= (2) × (3/8) × (5/8) = (30/64) = (15/32) = 0.46875
- Probability of drawing two blue marble in 2 draws with replacement = P(B) × P(B)
= (3/8) × (3/8) = (9/64) = 0.140625
The probability mass function of random variable X which represents the number of blue marbles draan in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
b) Probability of drawing one blue marble in 2 draws with replacement
= [P(B) × P(B')] + [P(B') × P(B)]
= (2) × (3/8) × (5/8) = (30/64) = (15/32) = 0.46875

USA scientific notation to express the diameter of a red blood cell that measures 0.00075 centimeters
Answer: 7.5×10^-4
Step-by-step explanation:
0.00075
Scientific notation means standard form
There are 3 zeros in front of the 7
So take the decimal to the back of 7
You have
7.5
Since you are counting backward, it will be negative
So we have
7.5×10^-4
Answer:
[tex]7.5 * 10^{-4}[/tex]
Step-by-step explanation:
Scientific notation is basically taking a decimal number and writing it as the product of a number between 1 and 10 (including 1 but excluding 10) and a power of 10.
Here, to get a number between 1 and 10, we see that 7.5 could work. However, if we have 7.5, we're disregarding all the zeros that came before it, which can't work. So, we need to take those into account by dividing 7.5 by 10000, which is the same as multiplying 7.5 by [tex]10^{-4}[/tex].
Thus, our final answer is the scientific notation: [tex]7.5 * 10^{-4}[/tex].

Mike purchased a round wall clock the clocks radius is 10m what is the circumference of the clock
Answer:
62.8 m
Step-by-step explanation:
The circumference of the clock is the circumference of a circle which is given by
2 Pi r
Where
Pi = 3.14
Radius r = 10m
Therefore
Circumference = 2 x 3.14 x 10
= 62.8 m
The circumference of the clock is approximately 62.8 meters.
Explanation:To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference and r is the radius of the circle. In this case, the radius of the clock is given as 10m. Substituting this value into the formula, we have C = 2π(10) = 20π. The approximate value of π is 3.14, so the circumference of the clock is approximately 20(3.14) = 62.8m.
To find the circumference (C) of a round wall clock, you can use the formula C = 2πr, where π (pi) is approximately 3.14 and r is the radius of the clock. In this case, the radius is given as 10 meters. Substituting this value into the formula, the circumference is calculated as C = 2 * 3.14 * 10 meters, which equals 62.8 meters.
Therefore, the circumference of Mike's round wall clock is approximately 62.8 meters. This value represents the total distance around the edge or perimeter of the circular clock face.
John surveyed 25 of his classmates about their music preferences7 students said they like hip-hop, 13 students said they pop, and 8 students said they liked neither hip-hop nor pop musicJohn made a Venn diagram to find the number of students who like both hip-hop and pop music Evaluate John's work Did he use the Venn diagram accurately to arrive at a correct solution?
Answer:
The venn diagram is not included in the question, but il try to answer it in a general way.
We have a sample of 25 persons.
7 of them like hiphop.
13 of them like pop
8 of them do not like neither.
So in our Venn diagarm we will have two circles, one for the students that like pop and other for the students that like hip-hop.
in the pop circle we have 13 students, in the circle of hiphop we have 7 students, and outside both circles we have 8 stundents.
Now, if we add it all we get:
13 + 7 + 8 = 28,
But we have 25 students, this means that 3 of the students like both genres, hip hop and pop.
Then the circles of hip hop and pop must have an intersection, and in the intersection we must have 3 students.
for which of the following conditions will the sum of integers m and n always be an odd number?
F. m is an odd integer
G. n is an odd integer
H. m and n are both odd integers
J. m and n are both even integers
K. m is an odd integer and n is an even integer
Answer:
Option K
m is an odd integer and n is an even integer
Step-by-step explanation:
The sum of intergers when one is even and another is odd results into an even number. Take for example, if x is even and the next number x+1 their sum will be 2x+1. The presence of +1 at the end shows the number is not divisible by 2 hence an odd number.
Practically, if you add 2+3=5 and 2 is even number while 3 is odd, clearly the sum being 5 is an odd number.
Otherwise, if you add two even numbers or two odd numbers the sum will be an even number.
Even numbers can be divided by 2 without leaving a remainder, while odd numbers can't.
The true condition is condition K: m is an odd integer and n is an even integer
If m is odd and n is odd, then the sum will be even
This means that: Conditions F, G and H cannot be true
As an illustration, we have:
[tex]m + n= 5+ 7[/tex]
[tex]m + n= 12[/tex]
12 is even.
The result will always be even, provided that m and n are odd numbers.
If m is even and n is even, then the sum will be even
This means that: Conditions J cannot be true
As an illustration, we have:
[tex]m + n = 6 + 8[/tex]
[tex]m + n =14[/tex]
14 is even.
The result will always be even, provided that m and n are even numbers.
If m is odd and n is even, then the sum will be odd
This means that: Conditions K is true
As an illustration, we have:
[tex]m + n = 6 + 7[/tex]
[tex]m + n = 13[/tex]
13 is odd.
The result will always be odd, provided that m is odd while, n is even.
Hence: the true condition is:
K. m is an odd integer and n is an even integer

What is a linear pair?A linear pair of angles is formed when two lines intersect at a single point. Angles are referred to as linear if they follow the intersection of the two lines in a straight line. The sum of the angles in a pair of linear equations is always 180°.
As per the given data:
From a horizontal line, a line is drawn such that it forms 2 angles, one ∠SPR = 119 degrees and one ∠QPR.
We have to find out the value of ∠QPR.
As the line is drawn from a horizontal line, it forms a linear pair.
From the linear pair property, the sum of the angles must be equal to 180 degrees as the line is horizontal.
After using the aforementioned property:
∠SPR + ∠QPR = 180°
119 + ∠QPR = 180
∠QPR = 180 - 119
∠QPR = 61°
Hence, The measure of angle ∠QPR is 61 degrees.

Mr. Mole and Bugs Bunny started digging their way into the ground from different locations at the same time. They each dug at a constant rate.
The following equation gives Mr. Mole's altitude (in meters relative to the ground) as a function of time (in minutes). A = -4-0.6t
Bugs Bunny's altitude (in meters relative to the ground) as a function of time (in minutes) is given by the following table of values:
Time (Minutes) Altitude (Meters)
2 -1.6
9 -7.2
16 -12.8
Who dug faster?
A) Mr. Mole
B) Bugs Bunny
C) They both dug at the same rate
Who started at a higher altitude?
A) Mr. Mole
B) Bugs Bunny
C) They both started at the same altitude
Answer:
Bugs bunny did both
Step-by-step explanation:
B
Bugs Bunny dug faster than Mr. Mole since his digging rate is -0.8 meters per minute compared to Mr. Mole's -0.6 meters per minute. Bugs Bunny also started at a higher altitude compared to Mr. Mole. This comparison involves understanding the rates of change from given functions and data points.
To determine who dug faster between Mr. Mole and Bugs Bunny, we need to compare their digging rates.
Comparing Digging Rates
Mr. Mole's altitude function is given by A = -4 - 0.6t. The rate at which Mr. Mole digs is represented by the coefficient of t, which is -0.6 meters per minute.
To find Bugs Bunny's digging rate from the table, we need to calculate the change in altitude over the change in time:From time 2 minutes (-1.6 m) to time 9 minutes (-7.2 m):Rate = (final altitude - initial altitude) / (final time - initial time)= (-7.2 - (-1.6)) / (9 - 2) = -5.6 / 7 ≈ -0.8 meters per minuteFrom time 9 minutes (-7.2 m) to time 16 minutes (-12.8 m):Rate = (final altitude - initial altitude) / (final time - initial time)= (-12.8 - (-7.2)) / (16 - 9) = -5.6 / 7 ≈ -0.8 meters per minuteSince Bugs Bunny's rate is -0.8 meters per minute and Mr. Mole's rate is -0.6 meters per minute, **Bugs Bunny dug faster**.
Comparing Starting Altitudes
Comparing their initial altitudes:
Mr. Mole's initial altitude is -4 meters (when t = 0).
From the table, Bugs Bunny's initial data point is at time 2 minutes, altitude -1.6 meters. To find his initial altitude, we assume constant rate from this point backward:
(-1.6 meters at 2 minutes) + (0.8 meters/minute × 2 minutes) = -1.6 + 1.6 = 0 meters
Thus, Bugs Bunny started at a higher altitude.

Given:
m∠WYX = 20°
m∠XYZ = 135°
To find:
The measure of arc WXZ.
Solution:
m∠WYZ = m∠WYX + m∠XYZ
m∠WYZ = 20° + 135°
m∠WYZ = 155°
The measure of inscribed angle is half of the intercepted arc.
[tex]$\Rightarrow m \angle WYZ = \frac{1}{2} m (ar WXZ)[/tex]
[tex]$\Rightarrow 155^\circ = \frac{1}{2} m (ar WXZ)[/tex]
Multiply by 2 on both sides.
[tex]$\Rightarrow 2\times 155^\circ = 2 \times \frac{1}{2} m (ar WXZ)[/tex]
