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.

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

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.

The lengths of the legs of a right triangle are 3 cm and 4 cm. What is the length of the hypotenuse?
To find the length of the hypotenuse of a right triangle with legs measuring 3 cm and 4 cm, use the Pythagorean theorem formula c = √(a² + b²). Plugging in the values gives c = √(9 + 16), which results in a hypotenuse of 5 cm.
The student is asking how to find the length of the hypotenuse of a right triangle when the lengths of the other two sides are given. In this case, the legs of the triangle are 3 cm and 4 cm long. To find the hypotenuse, we use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). This can be expressed as a formula: a² + b² = c². Solving for c, we can find the hypotenuse by taking the square root of the sum of the squares of the other two sides:
c = √(a² + b²)
Plugging in the values for a and b:
c = √(3 cm)² + (4 cm)²
c = √(9 cm² + 16 cm²)
c = √25 cm²
c = 5 cm
Therefore, the length of the hypotenuse is 5 cm.
Express ratio in simplest form 18 feet : 5 yards
Final answer:
To simplify the ratio 18 feet to 5 yards, convert yards to feet to get 15 feet, then divide both by the greatest common divisor, 3, ending up with a simplified ratio of 6:5.
Explanation:
To express the ratio 18 feet: 5 yards in simplest form, we first need to convert either yards to feet or feet to yards so that we are comparing the same units. Since we know that 1 yard is equal to 3 feet, we can multiply the number of yards by 3 to find out how many feet it equates to.
Now, let's calculate:
5 yards × 3 feet/yard = 15 feet
So the ratio 18 feet: 5 yards can be rewritten as 18 feet: 15 feet. To simplify this ratio, we divide both numbers by their greatest common divisor (GCD), which in this case is 3.
Here is the calculation:
18 feet ÷ 3 = 6
15 feet ÷ 3 = 5
Therefore, the ratio in simplest form is 6: 5.
