D. Timon chewed six gumballs in two hours
today and six gumballs in three hours
yesterday

Answers

Answer 1
Final answer:

To be a function, each input must correspond to exactly one output. In all cases except for Timon's gumballs, each distinct input yields a distinct output. Therefore, the sentence about Timon's gumballs does not represent a function.

Explanation:

In mathematical terms, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let's go through these situations separately:

Notebooks are sold in a four pack for $20 and a five pack for $25. Here, the input, or the number of notebooks, determines the output, or price. No two outputs are the same for any given input. This is a function.Shaunette charges $20 for one hour of babysitting and $40 for two hours. The input (hours) determines the output (price). Similar to the first example, no two outputs are the same for any one input. This is a function.Marcy drove 50 miles in one hour today and 100 miles in two hours yesterday. The input (time) determines the output (distance traveled). There is a unique output for each input. This is a function.Timon chewed six gumballs in two hours today and six gumballs in three hours yesterday. This time, for different inputs (different hours), the output (number of gumballs chewed) is the same. This does not comply with the definition of a function because a function should have a unique output for each input. Therefore, this sentence does not represent a function.

This is the first year Janis is playing softball. She has been practicing her batting. On her last swing the bat made an arc with a radius of 48 inches and swept through 255° of rotation. Assuming the arc is circular, what is the distance the tip of the bat travels in inches in terms of pi? How many feet is this in terms of pi?

Answers

Final answer:

Using the relation between arc length and the radius, the arc length covered by the bat tip for a swing of 255 degrees with a 48-inch radius bat is (85/6)π inches or (85/72)π feet.

Explanation:

The subject of the question is based in mathematics, specifically geometry. To solve the question, first, we have to know that the circumference (C) of a given circle is calculated as

2πr

, where 'r' is the radius. Since 255° is a portion of the total circumference (which is considered as 360°), we calculate the fraction of the total circumference covered by 255°, which is 255/360. The arc covered by Janis's bat swing is, therefore,

(255/360)*2πr

. Substituting 'r' with 48 inches, the arc length (As) comes to

(85/6)π inches

. To convert this to feet, divide the result by 12 (since there are 12 inches in one foot), which gives

(85/72)π feet

.

Describe the difference between an angle with a positive measure and an angle with a negative measure.

Answers

Answer:

negative is rotating counter clockwise and positive is straight

Step-by-step explanation:

positive 180 degresse rotation

Positive angles result from counterclockwise rotation, and negative angles result from clockwise rotation.

What are angles?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle.

The difference between the positive and negative angles :-

Angles are sometimes classified based on whether their values are more than or less than 0° into positive and negative angles. The measure of a positive or a negative angle depends on the amount of rotation between the two sides forming the angle. The rotation is measured from the initial side to the terminal side of the angle.

What is a Positive Angle :-

An angle formed by an anti-clock wise or counterclockwise rotation from its initial side is called a positive angle.

12°, 33°, 90°, 180°, 360° are all example of positive angles.

What is a Negative Angle :-

An angle formed by a clockwise rotation from its initial side is called a negative angle.

-9°, -45°, -110°, -280°, -310° are all example of negative angles.

Describe the transformations that maps triangle A to triangle A'.

A.translate 7 units to left and then reflect over the x-axis
B.translate 5 units to left and then reflect over the x-axis
C.translaté 7 units to right and then reflect over the x-axis
D.translate 5 units to right and then reflect over the x-axis

Answers

Answer:

c

Step-by-step explanation:

moving the figure over 7 units would put it directly over the a'

after that you can reflect the a over the x axis

The correct option is C. Translate [tex]7 \ units[/tex] to the right and then reflect over the x-axis.

To determine the transformations that map triangle [tex]\( A \)[/tex] to triangle [tex]\( A' \)[/tex]

1. Translation:

Observe the horizontal distance between the corresponding points of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].

Triangle [tex]\( A \)[/tex] is initially centered around [tex]\( x = 2 \)[/tex]., while triangle [tex]\( A' \)[/tex] is centered around [tex]\( x = 2 \)[/tex]

The horizontal distance from [tex]\(-5\)[/tex] to [tex]\(2\)[/tex] is [tex]\(7\)[/tex] units to the right.

2. Reflection:

Check the vertical positions of triangles [tex]\( A \)[/tex] and [tex]\( A' \)[/tex].

Triangle [tex]\( A \)[/tex] is above the x-axis while triangle [tex]\( A' \)[/tex] is below the x-axis. This indicates a reflection over the x-axis.

Thus, the correct transformation sequence is to translate triangle [tex]\( A \) 7 units[/tex] to the right and then reflect it over the x-axis.

Juanita is booking a 4-night stay at a hotel. The rate is $79 per room plus tax.
If state tax is 6%, city tax is 2%, and municipal tax is 1%, what is her total
lodging cost?

Answers

answer: you don’t specify if it’s $79 per night or $79 for all 4 nights, so i’ll give you 2 answers.

if it’s $79 per night, then the answer is $344.44

if it’s $79 for all 4 nights, then the answer is $86.11

Final answer:

To determine the total lodging cost for Juanita's 4-night stay, multiply the nightly rate by the number of nights to get the pre-tax cost, calculate the total tax rate and apply it to the pre-tax cost to find the tax amount, and then add this tax to the pre-tax cost for the total cost. The total lodging cost, including taxes, will be $344.44.

Explanation:

Juanita is trying to calculate the total cost of a 4-night stay at a hotel with a nightly rate and additional taxes. To find Juanita's total lodging cost, a multi-step calculation is required. First, calculate the cost before tax by multiplying the nightly rate by the number of nights. Then, calculate the total tax by adding the state, city, and municipal tax rates and applying this sum to the pre-tax cost to get the total tax amount. Finally, add the tax amount to the pre-tax cost to find the total cost of the stay.

The nightly rate is $79 and she is staying for 4 nights, so the initial cost (before tax) is calculated as follows:

79 x 4 = $316

To calculate the total tax, convert the percentages to decimals and sum them up as follows:

State tax (6%) = 0.06
City tax (2%) = 0.02
Municipal tax (1%) = 0.01
Total tax rate = 0.06 + 0.02 + 0.01 = 0.09

Multiply the total tax rate by the pre-tax cost to find the total tax amount:

0.09 x 316 = $28.44

Finally, add the tax amount to the pre-tax cost to get the total lodging cost:

316 + 28.44 = $344.44

The total cost for Juanita's 4-night stay at the hotel, including all taxes, is $344.44.

1 gallon of water weighs 8 1/3 pounds
30 gallons of water weighs x pounds

Answers

the answer would be 10 pounds

30 gallons of water weighs 250 pounds.

To find the weight of 30 gallons of water, we can use the given conversion factor that 1 gallon of water weighs 8 1/3 pounds.

First, let's find the weight of 1 gallon of water in pounds:

1 gallon = 8 1/3 pounds

Now, we can calculate the weight of 30 gallons of water:

30 gallons = 30 x (8 1/3 pounds)

= 30 x (25/3 pounds)

= 250 pounds

Therefore, 30 gallons of water weighs 250 pounds.

Solve the system of equations. y= 2x -3 y= x^2 -3

Answers

Answer:

(0, - 3 ) and (2, 1 )

Step-by-step explanation:

Given the 2 equations

y = 2x - 3 → (1)

y = x² - 3 → (2)

Substitute y = x² - 3  into (1)

x² - 3 = 2x - 3 ( subtract 2x - 3 from both sides )

x² - 2x = 0 ← factor out x from each term

x(x - 2) = 0

Equate each factor to zero and solve for x

x = 0

x - 2 = 0 ⇒ x = 2

Substitute these values into (1) for corresponding values of y

x = 0 : y = 2(0) - 3 = 0 - 3 = - 3 ⇒ (0, - 3 )

x = 2 : y = 2(2) - 3 = 4 - 3 = 1 ⇒ (2, 1 )

Answer:
