Which of the numbers below correctly describes 5,000 µf?
The number 5,000 µF represents a capacitance, indicating that the capacitor can store 5,000 microcoulombs of electric charge at an electric potential difference of 1 volt.
Explanation:The number 5,000 µF describes a capacitance. Capacitance is a measure of a capacitor's ability to store an electric charge. It can be defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential. So, when we say a capacitor has a capacitance of 5,000 µF (microfarads), it means the capacitor can store 5,000 micro coulombs of electric charge at an electric potential difference of 1 volt. It's important to know that the typical range of capacitors can vary from fractions of a picofarad (pF) to a milifarad (mF).

A customer pays $1,100 in state taxes on a newly purchased car. What is the value of the car if state taxes are 8.9% of the value?
$9,765.45
$10,876.90
$12,359.55
$14,345.48
$15,745.45
Final answer:
To find the value of the car, divide the amount of state taxes paid by the tax rate percentage. The value of the car is $12,359.55.
Explanation:
To find the value of the car, we need to divide the amount of state taxes paid by the tax rate percentage. In this case, the state taxes paid is $1,100 and the tax rate is 8.9%.
So, the value of the car can be calculated as follows:
Value of the car = State taxes paid / Tax rate percentage
= $1,100 / 0.089
= $12,359.55
Therefore, the value of the car is $12,359.55

what inequality represents "a cat weighs no more than 8 pounds"
Final answer:
The inequality representing "a cat weighs no more than 8 pounds" is expressed as w ≤ 8, where w symbolizes the cat's weight in pounds. This concept illustrates how inequality symbols are applied in algebra to represent the relationship between quantities, applicable in various real-world scenarios.
Explanation:
The question asks which inequality represents "a cat weighs no more than 8 pounds." In mathematical terms, this statement can be translated using an inequality symbol that indicates the cat's weight is either equal to or less than 8 pounds. The appropriate symbol for this is “≤”, which stands for “less than or equal to.” Therefore, the inequality that represents this statement is w ≤ 8, where w represents the weight of the cat in pounds.
Using inequality symbols to show how two metric measurements are related is a foundational concept in algebra, and it is crucial when working with real-world scenarios where quantities have upper or lower bounds. For instance, understanding this concept can apply to various situations such as determining the weight of a dog, or comparing soda in a can to ensure it does not exceed a certain weight limit. It's important to grasp how these symbols convey relationships between quantities.

Which shows the correct simplification of product of powers?
1.) 78 · 7-4 = 78· (–4) = 7–32
2.)78 · 7–4 = 78 ÷ (–4) = 7–2
3.)78 · 7–4 = 78 + (–4) = 74
4.)78 · 7–4 = 78 - (–4) = 712
The answer choice which shows the correct simplification of product of powers is:
78 · 7–4 = 78 + (–4) = 74What is Product of Powers?This refers to the mathematical property which states that when there is a multiplication of two powers that have the same base, then there would be the addition of exponents.
From the given choices, we can see that the powers are not given, so we can solve using inference.
This posits that (7^8) * (7^-4) was the product that was intended to be simplified and this law shows:
(A^m) * (A^n) = A^ (m+n)Hence, if we add the powers, then the correct answer would be option C because they are of the same base.

A function is defined as a relation between a set of inputs having one output each.
Input = 25 and output = $92.75
The cost of 25 pies is $92.75
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain of the function.
The outputs are called the range of the function.
Example: f(x) = 2 + 3x
x = 1
f(1) = 2 + 3x1 = 2 + 3 = 5
1 = Domain
5 = Range
We have,
c(x) = 49 + 1.75x
x = number of pies
The cost of producing 25 pies:
c(25) = 49 + 1.75 x 25
= 49 + 43.75
= $92.75
Thus the cost of 25 pies is $92.75

There are two major tests of readiness for college, the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores are approximately normal with mean μ = 21.5 and standard deviation σ = 5.4. sat scores are reported on a scale from 600 to 2400. the sat scores are approximately normal with mean μ = 1498 and standard deviation σ = 316. alyssa scores 30 on the act. assuming that both tests measure the same thing, what score on the sat is equivalent to alyssa's act score? (round your answer to a whole number.)
Assuming that both tests measure the same thing, the equivalent sat score is 1994
The given parameters are:
ACT scores
Mean, μ = 21.5
Standard deviation, σ = 5.4
Score, x = 30
SAT scores
Mean, μ = 1498
Standard deviation, σ = 316
Start by calculating the z-score for the act score using:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
[tex]z = \frac{30 - 21.5}{5.4}[/tex]
[tex]z = 1.57[/tex]
Next, calculate the z-score for the sat score using:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
This gives
[tex]z = \frac{x - 1498}{316}[/tex]
Substitute 1.57 for z
[tex]1.57 =\frac{x - 1498}{316}[/tex]
Multiply both sides by 316
[tex]496.12 =x - 1498[/tex]
Solve for x
[tex]x = 496.12 + 1498[/tex]
[tex]x = 1994.12[/tex]
Approximate
[tex]x = 1994[/tex]
Hence, the equivalent sat score is 1994

Final answer:
The equivalent SAT score to Alyssa's ACT score of 30 is calculated using Z-scores. The result is an SAT score of approximately 1996, rounded to the nearest whole number.
Explanation:
To determine what SAT score is equivalent to Alyssa's ACT score of 30, we use the concept of Z-scores. A Z-score represents the number of standard deviations an observation is from the mean of a distribution. The formula for calculating a Z-score is given by Z = (x - μ) / σ, where x is the score of interest, μ is the mean, and σ is the standard deviation.
First, we calculate the Z-score for Alyssa's ACT score:
ACT mean (μ) = 21.5
ACT standard deviation (σ) = 5.4
Alyssa's ACT score (x) = 30
Z-score for ACT = (30 - 21.5) / 5.4 ≈ 1.5741
Now we use Alyssa's ACT Z-score to find the equivalent SAT score by applying it to the SAT distribution. The SAT mean (μ) is 1498 and the SAT standard deviation (σ) is 316.Equivalent SAT score = SAT mean + (Z-score × SAT standard deviation)
Equivalent SAT score = 1498 + (1.5741 × 316) ≈ 1996
Therefore, rounding to the nearest whole number, the SAT score equivalent to Alyssa's ACT score of 30 is 1996.

To convert 5.0 cm to m, use the conversion factor of 1 m = 100 cm to get the result of 0.05 m.
Convert 5.0 cm to m:
1 m = 100 cm, which means 1 cm is 0.01 m.
Therefore, 5.0 cm is equal to 5.0 x 0.01 m = 0.05 m.
