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

What is a parent reciprocal
Answer:
Step-by-step explanation: The general form of a reciprocal function is r(x) = a / (x - h) + k. The graphs of reciprocal functions are made up of branches, which are the two main parts of the graph; and asymptotes, which are horizontal and vertical lines that the graph approaches but doesn't touch.
A small rectangular garden has an area of 80 square feet. Its length is 2 feet more than the width. Give both the length and width of the garden.
Answer:
The answer length is 10 and the width is 8 or the other way around.
Step-by-step explanation: The garden has a area of 80 square feet and since 10 has 2 more than 8 that the answer.
Final answer:
To find the length and width of the garden, set up the equation for the area of a rectangle: width times (width + 2) equals 80. Solving this gives us the width as 8 feet and the length as 10 feet.
Explanation:
The question asks us to find the length and width of a rectangular garden given that its area is 80 square feet and the length is 2 feet more than the width. We can represent the width with the variable w and then express the length as w + 2. To find the dimensions, we write the equation for the area of a rectangle (length × width):
w × (w + 2) = 80
Solving this quadratic equation gives:
w² + 2w - 80 = 0
Factoring the quadratic equation gives:
(w + 10) × (w - 8) = 0
Therefore, the width w could be 8 or -10. Since a negative width doesn't make sense for a garden, we take w = 8 feet as the width. Consequently, the length is w + 2 = 10 feet.
The dimensions of the garden are 8 feet by 10 feet or vice versa.

A. 168 m3
B. 31 m3
C. 1176 m3
D. Not enough information.
help please
A. 168 m3
Step-by-step explanation:
V = Bh
V = 24(7)
V = 168 m3
Answer:
i really dont know bro
Step-by-step explanation:
Sample response: Start by calculating the volume of the original prism. The area of the base, B, is 4(6) = 24 m2. Multiply that by the height to get the volume: 24(10) = 240 m3. Now, if you double all of the dimensions, you would have a rectangular prism with a base that is 8 m by 12 m and a height of 20 m. The area of the base, B, is 8(12) = 96 m2. Multiply that by the height to get the volume: 96(20) = 1,920 m3. To compare, look at the ratio of the original prism to the new prism: 96/1,920 = 1/8. The volume increases by 8 times the original volume.

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

Answer:
530.7?
Step-by-step explanation:
Answer: 530.7m
Step-by-step explanation:
The formula for the area of a circle is [tex]A=\pi r^2[/tex]
From the picture we can see that the diameter of the circle is 26m
The r, or radius of the circle is just half the diameter, thus the radius is 13m
Now that we have all the values of the variables, we can solve for A
Plug in 3.14 for π and 13 for r and solve
[tex]A=(3.14)(13)^2[/tex]
[tex]A=(3.14)(169)[/tex]
[tex]A=530.66m[/tex]
Exponential functions increase rapidly how would you describe the behavior of an inverse function to that
The exponential functions have the form f(x) = bˣ where b> 0 and b≠0.
Step-by-step explanation:
Exponential function is given in the form of f(x)= bˣ
When working with the inverse of a function, the inputs (x) and outputs(y) exchange their places and the inverse will be the reflection over the identity line y= x
The example of exponential function is the growth of bacteria. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours and it is written as f(x) = 2x.
The exponential function will be bigger than the polynomial and it always have the positive number other than 1 as the base.

Round only your final answer to the nearest
hundredth
4 cm
Answer:
The graph is missing, so there are two options m∠A = 36.87° or m∠A = 53.13°
Step-by-step explanation:
Assuming that 3 cm, 4 cm and 5 cm are the length of the sides of a triangle, then a right triangle is formed, in which 5 cm is the length of the hypotenuse and 3 cm and 4 cm are the length of the legs.
Angle A is either the angle between 4 cm and 5 cm sides or between 3 cm and 5 cm sides. For the first case:
cos(A) = adjacent/hypotenuse =
cos(A) = 4/5
A = arccos(4/5) = 36.87°
For the second case:
cos(A) = 3/5
A = arccos(3/5) = 53.13°
The measure of angle [tex]\( A \)[/tex] is approximately [tex]\( 53.13^\circ \)[/tex].
Given a right triangle [tex]\( \triangle ABC \)[/tex] with the following side lengths:
[tex]\( AB = 3 \) cm[/tex]
[tex]\( BC = 4 \) cm[/tex]
[tex]\( AC = 5 \) cm[/tex]
We need to find the measure of angle [tex]\( A \)[/tex].
Since [tex]\( \triangle ABC \)[/tex] is a right triangle, and the side lengths 3, 4, and 5 satisfy the Pythagorean theorem [tex](\( 3^2 + 4^2 = 5^2 \))[/tex], we can proceed to use trigonometric ratios to find the measure of angle [tex]\( A \)[/tex].
Using Trigonometric Ratios
The trigonometric function tangent is often used in right triangles. The tangent of an angle in a right triangle is the ratio of the opposite side to the adjacent side.
For angle [tex]\( A \)[/tex]:
[tex]\[\tan(A) = \frac{\text{opposite}}{\text{adjacent}} = \frac{BC}{AB} = \frac{4}{3}\][/tex]
To find the measure of angle [tex]\( A \)[/tex], we use the arctangent (inverse tangent) function:
[tex]\[A = \tan^{-1}\left(\frac{4}{3}\right)\][/tex]
[tex]\[A \approx \tan^{-1}(1.3333) \approx 53.13^\circ\][/tex].
The complete question is:
What is measure of angle A?
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

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.

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].
