Answer: x=1
Step-by-step explanation:
Since the angles are vertical that means they have to be equal.
So we can set the two equations equal to each other.
10 - x = 4x + 5
10 = 5x + 5
5 = 5x
x=1
Answer:
10 - x = 4x + 5
10 - 5 = 4x - x
5 = 3x
x = 1.6
x = 1.6
angle 1 = 10-1.6
= 8.4
angle 2 = 4(1.6)+5
= 11.4

Four points are drawn on the coordinate plane and connected with straight lines to form a rectangle. Three of the vertices of the rectangle are located at (2, 1), (2, 4), and (-4, 4). What are the coordinates of the fourth vertex of the rectangle? What are the dimensions of the rectangle? What is the area of the rectangle?
Answers
To find the fourth vertex of the rectangle, we can start by drawing a diagram:
========================================
|
| (2,4)
|
--------.--------
|
(?, ?) | (2,1)
|
========================================
We know that opposite sides of a rectangle are parallel, so the fourth vertex must be located on the same horizontal line as the point (2, 1) and the same vertical line as the point (-4, 4). Therefore, the fourth vertex must be located at (-4, 1).
To find the dimensions of the rectangle, we can find the distance between the points (2, 1) and (2, 4) to get the length of one side, and the distance between the points (2, 1) and (-4, 1) to get the length of the other side.
Length = 4 - 1 = 3
Width = 2 - (-4) = 6
So the dimensions of the rectangle are 6 by 3.
To find the area of the rectangle, we can multiply the length and width together:
Area = Length x Width = 6 x 3 = 18 square units.
Width is 2+4
Length times width is going to get you 18 which is your final answer

A train is early 1/6 of the time, on time 1/2 of the time, and late 1/3 of the time. Doreen wants to know the probability that the train will be late two times in a row. Explain how two 1-6 number cubes can be used to simulate this situation.
Answers
Answer:
Step-by-step explanation:
1/2 = 3/6 (on time)
1/3 = 2/6 (late)
1/6 = 1/6 (early)
3 times 2 is 6. You need the same denominators. What you do to the bottom you do to the top. So, 3x2=6 and 1x2=2. Therefore, you have 2/6. The 2 cubes can be used to show the probability of the train being late because we now know it is late 2/6 times and either early or on time 4/6 times.

How many faces does a square pyramid not including it's base
Answers
Answer: A square pyramid has 5 faces, 8 edges, and 5 vertices.
Step-by-step explanation:
The required answer is a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.
To determine the number of faces excluding the base, we can follow these steps:
Step 1: Identify the number of triangular faces.
In a square pyramid, there are four triangular faces that connect each corner of the square base to the apex (the top vertex). These triangular faces do not include the base.
Step 2: Determine the total number of faces.
In addition to the triangular faces, we need to consider the base of the pyramid. The base is a square, and it is not counted when we exclude the base. Therefore, the number of faces excluding the base is the same as the number of triangular faces.
Step 3: Calculate the number of faces.
Since we determined that a square pyramid has four triangular faces, the square pyramid (excluding the base) has four faces.
Hence, a square pyramid (excluding the base) has four faces. A square pyramid consists of a square base and triangular faces that meet at a common vertex.

The probability of flipping a coin and having it land on heads is 1/2. If a coin is tossed 4 times, how many times can you expect it to land on heads?
Answers
Answer:
we can expect the coin to land on heads 2 times out of 4 tosses.
Step-by-step explanation:
If the probability of flipping a coin and having it land on heads is 1/2, then the probability of it landing on tails is also 1/2.When a coin is tossed 4 times, each toss is an independent event, meaning the outcome of one toss does not affect the outcome of another toss. Therefore, we can use the binomial probability formula to find the expected number of times the coin will land on heads:Expected number of heads = n * pwhere n is the number of trials (4 tosses) and p is the probability of success (1/2 or 0.5 in this case).Plugging in the values, we get:Expected number of heads = 4 * 0.5 = 2

We know already that desk A and desk B are on the same column, since both coordinates' x factors are 7. So all we need to do now is find the difference of 2 and -8. So, we get the [very simple] equation [tex]2 - (-8) = d[/tex]. Now, when you subtract a negative, it's pretty much just adding, so we can simplify this equation to [tex]2 + 8 = d[/tex], and we all know [tex]2 + 8 = 10[/tex]. So the distance between the two desks is 10 units.

To find the area of the parallelogram formed by the points (-5, 2), (2, 0), and (4, -4), we need to first find the fourth vertex of the parallelogram. Since opposite sides of a parallelogram are parallel and have equal length, the fourth vertex can be obtained by adding the vector formed by the points (-5, 2) and (2, 0) to the point (4, -4). This gives us the fourth vertex as (11, -6).
Next, we can use the distance formula to find the lengths of the two sides of the parallelogram. The length of the side connecting (-5, 2) and (2, 0) is sqrt(45), and the length of the side connecting (2, 0) and (4, -4) is 2sqrt(5).
Finally, we can use the formula for the area of a parallelogram, which is base times height, to find the area of the parallelogram. The base of the parallelogram is the distance of sqrt(45) between (-5, 2) and (2, 0), and the height is the distance of 2sqrt(5) between (2, 0) and (4, -4). Multiplying these values together gives us an area of 42 square units, which is option C.

A. n = 0.32t
B. n = 0.68t
C. n = 32t
D. n = 68t
PLS ANSWER!
Answers
Answer:
The percentage of earrings is 32%, which means that the remaining percentage of jewelry items that are not earrings is 100% - 32% = 68%. Therefore, the equation that represents the relationship between the number (n) of jewelry items that are not earrings and the total number (t) of jewelry items produced is: n = 0.68t So, the correct answer is B.
B) n = 0.68t.
If 32% of the jewelry items produced are earrings, then 68% of the jewelry items produced are NOT earrings. Therefore, the equation for n is n = 0.68t.

[tex]4p( p- 7p) = {4p}^{2} - {28p}^{2} [/tex]
GOOD LUCK:)
The factorized value of the equation is solved and A = 4p² - 28pq
What is Factorizing?Brackets should be expanded in the following ways to factorize an expression
For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket
For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = 4p ( p - 7q )
4p(p-7q) can be expanded as follows:
4p(p-7q) = 4p * p + 4p * (-7q)
A = 4p² - 28pq
Hence , the expanded form of 4p(p-7q) is 4p² - 28pq

Find the probability of showing either
prime number on the first die or multiple of 5 on the second die
Answers
Step-by-step explanation:
The sample space for rolling two dice consists of 36 possible outcomes, as each of the six faces on the first die can be combined with any of the six faces on the second die.
To find the probability of showing either a prime number on the first die or a multiple of 5 on the second die, we can use the principle of inclusion-exclusion.
There are 3 prime numbers on a standard die: 2, 3, and 5. And there are two multiples of 5: 5 and 10. However, we need to be careful not to count the outcome (5,5) twice, as it satisfies both conditions.
So, the probability of showing either a prime number on the first die or a multiple of 5 on the second die is:
P(prime or multiple of 5) = P(prime) + P(multiple of 5) - P(prime and multiple of 5)
P(prime) = 3/6 = 1/2
P(multiple of 5) = 2/6 = 1/3
P(prime and multiple of 5) = 1/36
Therefore,
P(prime or multiple of 5) = 1/2 + 1/3 - 1/36
= 19/36
So the probability of showing either a prime number on the first die or a multiple of 5 on the second die is 19/36, or approximately 0.528.
