Answer:
2.8867
Step-by-step explanation:
9.8x+17=7.6x-16
We move all terms to the left:
9.8x+17-(7.6x-16)=0
We get rid of parentheses
9.8x-7.6x+16+17=0
We add all the numbers together, and all the variables
2.2x+33=0
We move all terms containing x to the left, all other terms to the right
2.2x=-33
x=-33/2.2
x=-2.8867

Step-by-step explanation:
Write an algebraic expression to represent the pay (in dollars) for working "x" hours at a rate of eight dollars and seventy-five cents per hour.A) 8.75xB) 875xC) 8.75xD) 875x
Step-by-step explanation:
Hours worked = X
Money earned per hour = $8.75
Your answer would be A.
E.g.) Say that there is another part to this question.
You work for 3 hours, how much money would you earn after three hours? Use your equation "8.75x"
We know that "x" is equal to the hours worked, so plug in 3 for x.
8.75x = 8.75 *x
8.75 * 3= 26.25
So, if you worked 3 hours, your total pay would be $26.25 (Note: this is not part of your answer, just an example to show you how equations work)
Hope this helps :)

Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Zach is 4 years older than twice his sister Maya’s age. Zach is 28 years old.
Answer: 2m + 4
100% positive
⇒Since it is given that variable m should be the one to be used,
it is said that Zach is 4 years older⇒ than twice his sister Maya`s age.
⇒As indicated Maya`s age is m
⇒Twice Maya`s age is 2×m=2m
Therefore Zach`s age is 2m+4
The expression given by the given scenario is 2m+4
⇒It is the expression that can help us find the exact ages of the Zach and Maya

The spinner has a total of 6 possible outcomes, and each outcome has a different probability of occurring. To find the probability of an outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.
The possible outcomes and their frequencies are:
2 appears once
6 appears twice
8 appears three times
Therefore, the probabilities of the different outcomes are:
P(2) = 1/6 = 0.1667 or approximately 16.67%
P(5) = 0/6 = 0 or 0%
P(6) = 2/6 = 0.3333 or approximately 33.33%
P(8) = 3/6 = 0.5 or 50%
Note that the sum of all the probabilities must equal 1, since one of the outcomes must occur. In this case, 0.1667 + 0 + 0.3333 + 0.5 = 1, so we can be confident that we have calculated the probabilities correctly.
What is Probability?Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is concerned with predicting the likelihood of a particular event occurring based on the available information.
In probability, an event is a set of outcomes, and the probability of an event is a number between 0 and 1 that indicates the likelihood of the event occurring. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.
In order to calculate probabilities, we need to identify the possible outcomes of an event and determine how likely each outcome is. The sum of the probabilities of all possible outcomes must always equal 1.
In the example given, the spinner has six possible outcomes, and each outcome has a different probability of occurring. By dividing the number of ways each outcome can occur by the total number of possible outcomes, we can calculate the probability of each outcome.
Probability is used in many fields, including statistics, finance, and science. It is an important tool for decision-making and risk analysis, and it can help us to make predictions about future events based on past data.

15. Tamika eats jellybeans at a rate of 12 jellybeans every 4 minutes. It takes her 30
minutes to eat the snack size pack of jellybeans. Her brother, James, eats jellybeans at a
rate of 28 jellybeans
every 7 minutes. How many fewer minutes does it take James
to eat a snack size pack of jelly beans compare to Tamika?
Answer:
Step-by-step explanation:
tamika eats jelly beans at a rate of 3 jellybeans ber miniute since it would be 12/4. and it takes tamika 30 minutes which means that the snack pack had 90 jellybeans.
James eats jellybeans at a rate of 4 jellybeans per miniute so it took james 22.5 miniutes to eat a snack pack.
so you would subtract tamikas minutes(30 min) - james minutes(22.5) and get 7.5 minutes.
James took 7 minutes and 30 seconds less than Tamika to eat his jelly beans.
James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika
What is a unit rate?A unit rate means a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
Tamika:
Rate of eating jellybeans = 12 jelly beans per 4 minutes.
12 beans = 4 minutes
Divide it by 4 into both sides
We get,
3 beans = 1 minute ___(1)
Tamika took 30 minutes to finish snack-size beans.
This means from (1),
3 x 30 jelly beans= 30 minutes
90 jelly beans = 30 minutes
There are 90 jellybeans in snack-size beans.
James:
Rate of eating the jellybeans = 28 jellybeans per 7 minutes
It can be written as:
28 jelly beans = 7 minutes
Multiplying 90/28 on both sides we get,
90 jelly beans = (90/28) x 7 minutes
90 jelly beans = 90/4 minutes = 22.5 minutes
This means James takes 22.5 minutes to finish snack-size jelly beans.
We see that,
The time took for Tamika to finish snack-size jelly beans = 30 minutes
The time took for James to finish snack-size jelly beans = 22.5 minutes
we have,
30 - 22.5 = 7.5
Thus,
James took 7.5 fewer minutes to eat a snack-size pack of jelly beans as compared to Tamika

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16
Simplifying:
V ≈ 1363.04 cubic inches

Describe what happens to the Car as it moves from BLUE to B"L"U"E".
Answer: As the car moves from "BLUE" to "B"L"U"E", it slows down its acceleration, reaches its maximum velocity, and then decelerates. The change in the car's motion is due to the change in the slope of the graph from positive to zero to negative. At "BLUE", the car has the highest positive slope, which represents the maximum acceleration. As the car moves towards "B"L"U"E", the slope of the graph decreases and becomes zero at the highest point of the graph. At this point, the car has reached its maximum velocity, and it starts to decelerate towards "B"L"U"E". Finally, at "B"L"U"E", the slope of the graph is negative, indicating that the car is decelerating.
