Answer:
2i-/3
Step-by-step explanation:
This question involves imaginary numbers and simplifying radicals.
Which steps would you take to solve this equation? Check all that apply.
4p = 12
Divide by 4 on both sides of the equation.
Divide by 12 on both sides of the equation.
StartFraction 4 Over 4 EndFraction = 1 and StartFraction 12 Over 4 EndFraction = 3, so p = 3.
Substitute 12 for p and multiply to check the solution.
Substitute 3 for p and multiply to check the solution.
The correct steps are:
- Divide by 4 on both sides of the equation.
- Substitute 3 for p and multiply to check the solution.
To solve the equation 4p = 12, the following steps would be taken:
1. Divide by 4 on both sides of the equation. This step would simplify the equation to p = 12/4.
2. Substitute 12 for p and multiply to check the solution. This step would involve substituting 3 for p and multiplying, not substituting 12.
3. Substitute 3 for p and multiply to check the solution. This step is the correct approach to verify if the value of p obtained is a solution to the original equation.
So, the correct steps are:
- Divide by 4 on both sides of the equation.
- Substitute 3 for p and multiply to check the solution.

The figure contains a right triangle. The side opposite the right angle is 8. The side opposite the 60 degree angle is x.
Answer:
[tex]4\sqrt{3}[/tex]
Step-by-step explanation:
Since the triangle is a right triangle with a 60 degree angle, the triangle is what can be referred to as a 30-60-90 triangle. In this type of triangle, the larger leg (the one opposite the 60 degree angle) is [tex]\sqrt{3}[/tex] times larger than the smaller leg (the one opposite the 30 degree angle). Also, the hypotenuse (the side opposite the right angle) is twice larger than the smaller leg. Since the smaller leg is 8/2=4 units long, x is [tex]\sqrt{3}[/tex] larger than that or just [tex]4\sqrt{3}[/tex]. Hope this helps!
Answer:
4√3
Step-by-step explanation:
We can use trig functions since this is a right triangle
The side opposite the right angle is 8, that is the hypotenuse
We know the opposite side is x
sin theta = opp/ hyp
sin 60 = x/8
Multiply each side by 8
8 sin 60 =x
sin 60 = sqrt(3)/2
8 (sqrt(3)/2 =x
4 sqrt(3) =x

a farmer is putting up a rectangular pasture. it measures 320 feet by 335 feet it costs $8 per foot, how much will it cost
Final answer:
The total cost to fence a rectangular pasture measuring 320 feet by 335 feet at $8 per foot is $10,480. The cost is calculated by finding the perimeter of the rectangle (1310 feet) and multiplying it by the cost per foot.
Explanation:
To calculate the cost of fencing a rectangular pasture measuring 320 feet by 335 feet at a rate of $8 per foot, we need to find the perimeter of the rectangle and then multiply it by the cost per foot.
The perimeter (P) of a rectangle can be found using the formula P = 2(length + width). In this case:
Length (L) = 320 feet
Width (W) = 335 feet
So, the perimeter P = 2(L + W).P = 2(320 feet + 335 feet)P = 2(655 feet)P = 1310 feetNow, to find the total cost, we multiply the perimeter by the cost per foot:
Total Cost = Perimeter × Cost per foot
Total Cost = 1310 feet × $8/foot
Total Cost = $10,480
Therefore, the total cost to fence the entire pasture will be $10,480.

Answer: Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.
Step-by-step explanation:
4x - x + 5 = 8 - 3x - 3
Combine like terms
4x - x + 5 = 5 - 3x
Subtract x from 4x
3x + 5 = 5 - 3x
Add -3x to both sides
6x + 5 = 5
Subtract 5 from each side
6x = 0
Divide by 6
x = 0
Put 0 into the equation
4(0) - 0 + 5 = 8 - 3(0) - 3
Multiply
0 - 0 + 5 = 8 - 0 - 3
Subtract
5 = 5

A jar contains 2 green marbles, 4 blue marbles, 3 yellow marbles, and 2 black marbles. A
marble is chosen at random from the jar and replaced. Then a second marble is chosen
at random. Find the probability of the first marble being green and the second marble
being yellow.
Answer:
We start with 11 marbles. The first marble selected is green, so P(green) = 2/11. Since this marble is replaced, we still have the same 11 marbles. The second marble selected is yellow, so P(yellow) = 3/11. It follows that P(green, then yellow) = (2/11)(3/11) = 6/121.
An angle that turns through 1/360 of a circle and measures 360 degrees is called a ________ angle.
A. Unit
B. Straight
C. Obtuse
An angle that turns through 1/360 of a circle and measures 360 degrees is called a (A) Unit angle.
An angle that turns through [tex]\( \frac{1}{360} \)[/tex] of a circle and measures 360 degrees is called a Unit angle. This term is associated with the concept of angular measurement, where a full circle is divided into 360 equal parts, each known as a degree. Therefore, an angle that subtends [tex]\( \frac{1}{360} \)[/tex] of this circle is referred to as a "unit angle."
The options provided are:
A. Unit: This is the correct answer. A unit angle is precisely the measure of [tex]\( \frac{1}{360} \)[/tex] of a circle, and in this case, it corresponds to 360 degrees.
B. Straight: A straight angle measures 180 degrees and is formed by two opposite rays. It is not directly related to the concept of [tex]\( \frac{1}{360} \)[/tex] of a circle.
C. Obtuse: An obtuse angle measures more than 90 degrees but less than 180 degrees. It is not the appropriate term for an angle that turns through [tex]\frac{1}{360}[/tex] of a circle and measures 360 degrees.
In summary, the correct term for an angle that turns through [tex]\( \frac{1}{360} \)[/tex] of a circle and measures 360 degrees is a Unit angle (option A).

Step-by-step explanation:
the answer is 20
The angles are supplementary angles. Then the value of the variable 'x' will be 20.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Angle 7x and angle (x + 20) is the supplementary angles. Then the equation is given as,
7x + x + 20 = 180
Simplify the equation, then we have
7x + x + 20 = 180
8x = 160
x = 20
The angles are supplementary angles. Then the value of the variable 'x' will be 20.

In mathematics, a relation is a function if each input has a unique output. This one-to-one correspondence distinguishes functions, vital for modeling relationships and solving mathematical problems.
In mathematics, a relation is considered a function if each input (or element from the domain) corresponds to exactly one output (or element in the range).
Every element in the domain is associated with a unique element in the range.
A function is a specific type of relation between two sets, usually called the domain and the range.
In a function, each element in the domain is paired with exactly one element in the range.
Function Notation:
If f is a function, we often use the notation f(x) to represent the output (or value in the range) corresponding to the input x in the domain.
Key Criteria for a Relation to be a Function:
Domain-Range Pairs: Each element in the domain must be paired with an element in the range.
Uniqueness: Each element in the domain must have a unique partner in the range. No two different elements in the domain can have the same output.
Testing for a Function:
Vertical Line Test: If any vertical line intersects the graph of the relation at more than one point, the relation is not a function.
Mapping Diagram: A mapping diagram can visually represent the pairing of elements from the domain to the range.
Example:
Consider the relation where each person is paired with their date of birth. This is a function because each person has a unique date of birth.
Notation for Functions:
A function f is often denoted as f:A→B, where A is the domain and B is the codomain.
Therefore, a relation is a function if each input value maps to only one output value.

D. 0.45 miles
Answer:
D. 0.45 miles
Step-by-step explanation:
Change all so they have a common measurement. Convert:
0.45 miles = 2376 feet.
450 feet = 450 feet.
45 yards = 135 feet
4500 inches = 375 feet.
0.45 miles is the largest distance.

Helpppl!!! In 2011,Miami-Dade County had a population of about 2.55 million people and covered an area of about 5000 square kilometers. What was the approximate population density of Miami-Dade County in 2011? A) 5100 people per square kilometer. B)1960 people per square kilometer. C) 510 people per square kilometer. D) 196 people per square kilometer
Answer:
C) 510 people per square kilometer
Step-by-step explanation:
Population Density = Population/Area
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
The approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.
What is population density?Population density is a measurement of population per unit of land area.
Given that, in 2011,Miami-Dade County had a population of about 2.55 million people and covered an area of about 5000 square kilometers.
We need to find the population density of Miami-Dade County in 2011
So,
To calculate the population density, you will divide the population by the size of the area.
Thus, Population Density = Number of People/Land Area.
The unit of land area should be square miles or square kilometers.
Therefore,
= 2,550,000/5000
= 2,550/5
= 510 people per square kilometer
Hence, the approximate population density of Miami-Dade County in 2011 was 510 people per square kilometer.
