A number z is fewer than 34.
Final answer:
The letter 'z' in mathematics can refer to various concepts including complex numbers with arguments measured in degrees, z-scores in statistics indicating deviation from the mean, and as a variable within equations and inequalities.
Explanation:
The concept of 'z' seems to refer to multiple mathematical contexts, including complex numbers, z-scores in statistics, and equations involving z. Specific examples from the information provided include:
Complex numbers where z's argument could be positive or negative, and use of degrees in the context of a circle's 360 degrees showing that -30 and 330 degrees represent the same angle.
The z-score, which measures how many standard deviations a data point is from the mean in statistics, such as z = -4 indicating a data point four standard deviations to the left of the mean.
Equations where z is a variable representing a number, which could be within a certain range or satisfying a given condition.
Understanding these uses of z in the mathematical context allows for precise interpretation of equations, probabilities, and analyses of data sets.
The inequality that represents the statement "A number z is fewer than 34." is: z < 3/4.
How to express the inequality?
The inequality that represents the word sentence "A number z is fewer than 3/4" is z < 3/4.
To explain this, we can compare z to 3/4. If z is smaller than 3/4, we can use the less than symbol (<) to represent this relationship.
So, the inequality is z < 3/4.
For example, if z is 1/2, which is smaller than 3/4, the inequality holds true: 1/2 < 3/4.
Complete question is:

Stefan is measuring the angles of a triangle. He measures the first angle and gets a measure of 80° What does he know about the other two angles? A) They are each 50°. B) Their measures should add up to be 100°. C) Their measures should add up to be 280°. D) He doesn't know anything about the other two angles.
The answer is (B) Their measures should add up to be 100°.
Step-by-step explanation:We know that the sum of all angles of a triangle is equal to 180 degrees. Stefan has calculated the first angle and it came out to be 80 degrees. So the other two angles must be equal to 100 in order to complete the total measurement of triangle angles which is 180.

Explain how you would solve a triangles given two sides and the included angle?
To solve a triangle given two sides and included angle, use the law of cosines. This law is expressed as a² = b² + c² - 2bc cos(A), where a, b, c are the lengths of the sides, and A is the included angle.
Explanation:To solve a triangle given two sides and the included angle, you would use the Law of Cosines. This law is used when you're given two sides and the included angle in a triangle (often abbreviated as SAS). The law states,
a² = b² + c² - 2bc cos(A)
where a, b, and c are the lengths of the sides of the triangle, and A is the included angle. So, in this case, if you're given sides b and c and included angle A, you would substitute these values into the formula to find side a.
For instance, if side b is 3 units, side c is 4 units, and angle A is 60 degrees, we would substitute these values into our formula like so: a² = 3² + 4² - 2(3)(4) cos(60).

Step-by-step explanation:
joey's little sister must take four steps for every three steps joey takes. suppose one step of joey's covers one foot. how many feet would his sister
Joey's sister takes 0.75 foot for each step she takes since she takes four steps for every three of Joey's, and Joey's step is 1 foot.
The question revolves around a ratio of steps taken by Joey and his sister. Since Joey's one step covers one foot and his sister takes four steps for his three, we need to determine how many feet his sister covers for each of Joey's steps. Let's use a ratio to figure this out.
First, we establish the ratio of steps: for every 3 steps Joey takes, his sister takes 4. If Joey's 3 steps equal 3 feet (because 1 step = 1 foot), we then find the length of his sister's step compared to his. We divide the 3 feet by Joey's 3 steps to find that each step Joey takes is 1 foot long. Then, we calculate his sister's step length in feet by dividing the 3 feet by 4 (since she takes 4 steps to his 3), which equals 0.75 foot per step for his sister.
So, for each of Joey's steps being 1 foot, his sister's step would be 0.75 foot. Therefore, Joey's sister covers 0.75 foot for each step she takes.

A veterinary clinic plans to build four identical dog kennels along the side of its building using 210 feet of fencing. (See the picture.) What should be the dimensions of each kennel to maximize the enclosed area? (Note: No fencing is needed along the side of the building.)
Final answer:
To maximize the enclosed area, each kennel should be in the shape of a square with dimensions of 52.5 feet by 52.5 feet.
Explanation:
To maximize the enclosed area, each kennel should be in the shape of a square. Let's assume that each side of the square kennel has a length of x feet.
Each kennel has four sides, so the total length of fencing required for all four kennels is 4x feet.
Given that there are 210 feet of fencing available, we can set up the equation 4x = 210 and solve for x to find the length of each side of the square kennel.
Dividing both sides of the equation by 4, we get x = 52.5 feet.
Therefore, each kennel should have dimensions of 52.5 feet by 52.5 feet to maximize the enclosed area.

a rectangle has an area of 156 square inches and a perimeter of 50 in what are the width and the length of the rectangle
Final answer:
To find the length and width of the rectangle with an area of 156 square inches and a perimeter of 50 inches, we can set up and solve a system of equations based on the area and perimeter formulas. After solving, we determine that the length is 13 inches and the width is 12 inches.
Explanation:
The student has asked to find the length and width of a rectangle given that it has an area of 156 square inches and a perimeter of 50 inches. To solve this problem, we need to use the formulas for the area and perimeter of a rectangle.
Area and Perimeter Formulas
Area formula: A = length × width
Perimeter formula: P = 2(length + width)
Let's denote the length as 'l' and the width as 'w'. The area of the rectangle is 156, so we can write:
l × w = 156
The perimeter of the rectangle is 50, so we can write the perimeter formula as:
2(l + w) = 50
This simplifies to:
l + w = 25
Now, we have two equations:
l × w = 156
l + w = 25
We can solve this system of equations by expressing one variable in terms of another. Let's express 'w' in terms of 'l' from the second equation:
w = 25 - l
Now, substitute 'w' in the area equation:
l × (25 - l) = 156
This is a quadratic equation that can be solved to find the values of 'l'. Once we have 'l', we can find 'w' using the second equation.
After solving, we find that the length is 13 inches and the width is 12 inches. Therefore, the rectangle's dimensions are 13 inches by 12 inches.
A vehicle travels a distance of 5t4 − 10t2 + 6 miles in t + 2 minutes.
The vehicle's speed is __________miles/minute.
Answer:
Speed of the vehicle=[tex]\frac{5t^{4}-10t^{2}+6}{t+2}miles/min[/tex]
Step-by-step explanation:
Given that,
Distance traveled by the vehicle = 5t⁴ - 10t² + 6 miles
time = t + 2 minutes
We need to find the speed of vehicle. Use the formula of speed is:
[tex]Speed=\frac{Dstance}{Tme}[/tex]
[tex]Speed=\frac{5t^{4}-10t^{2}+6}{t+2}[/tex]
So, speed of the vehicle=[tex]\frac{5t^{4}-10t^{2}+6}{t+2}[/tex]
That's the final answer.
Answer:
The speed is 5t^3 - 10t^2 + 10t - 20 + 46/(t+2) miles per minute.

Yi and Sue play a game. They start with the number $42000$. Yi divides by a prime number, then passes the quotient to Sue. Then Sue divides this quotient by a prime number and passes the result back to Yi, and they continue taking turns in this way.
For example, Yi could start by dividing $42000$ by $3$. In this case, he would pass Sue the number $14000$. Then Sue could divide by $7$ and pass Yi the number $2000$, and so on.
The players are not allowed to produce a quotient that isn't an integer. Eventually, someone is forced to produce a quotient of $1$, and that player loses. For example, if a player receives the number $3$, then the only prime number (s)he can possibly divide by is $3$, and this forces that player to lose.
Who must win this game, and why? Explain your reasoning in complete sentences. (Don't just show one example of how the game could go. Instead, explain why the same player must always win, no matter what strategy either player tries to use!)
Is Sylvia buys 5 shirts for $75 a unit rate?
I believe you are finding the total cost of 5 shirts given the unit rate. To compute for the total cost, you have to multiply the unit rate to the number of shirts bought:
5 shirts x $75 unit rate = $375
Therefore, Sylvia will spend $375 to buy 5 shirts.
