∠2 = 60°, ∠3 = 120°, ∠4 = 60°, ∠5 = 120°, ∠6 = 60°, ∠7 = 120° and ∠8 = 60
Two column Proof:
A two-column geometric proof consists of a list of statements and the reasons why we know these statements are true. The complaints are listed in the left column and the reasons for the complaint are listed in the right column.
According to the Question:
l II m and p is their transversal and 1 = 120°
∠1 + ∠2 = 180 °(Straight line)
120° + ∠2 = 180° > ∠2 = 180° - 120° = 60°
∠2 = 60°
But ∠1 = ∠3 (Vertically opposite angles)
∠3 = ∠1 = 120°
Similarly ∠4 = ∠2
By Vertically opposite angles,
∠4 = 60°
∠5 = ∠1 (Corresponding angles)
∠5 = 120°
Similarly, by corresponding angles:
∠6 = ∠2
∠6 = 60°
∠7 = ∠5 (Vertically opposite angles)
∠7 = 120°
And,
∠8 = ∠6 (Vertically opposite angles)
∠8 = 60°
Hence ∠2 = 60°, ∠3 = 120°, ∠4 = 60°, ∠5 = 120°, ∠6 = 60°, ∠7 = 120° and ∠8 = 60°

The small box was 1/4 of a meter shorter than the medium box. If the boxes are all stacked on top of each other, what is their combined weight
If the boxes are all stacked on top of each other, what is their combined height is 11/8
Height of large box = 7/8m
Height of medium box = 2/6m shorter than large box
Height of small box = 1/4m shorter than the medium box
Calculating the height of the medium and small boxes.
Medium box height x large box height

Keshawn has � x nickels and � y dimes, having a maximum of 14 coins worth a minimum of $1 combined. A maximum of 4 of the coins are nickels. Solve this system of inequalities graphically and determine one possible solution. Number\
One possible solution is Keshawn has 2 nickels and 12 dimes.
What is inequality equation?
An inequality equation is a mathematical expression that compares two values or expressions using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to)
To solve the system of inequalities graphically, we can plot the two inequalities on the coordinate plane and shade the region that satisfies both inequalities. Let x be the number of nickels and y be the number of dimes.
The first inequality represents the maximum number of coins:
x + y ≤ 14
The second inequality represents the minimum value of the coins:
0.05x + 0.1y ≥ 1
We can rewrite this inequality as:
x + 2y ≥ 20
Now we can plot these two inequalities on the coordinate plane:
Draw a horizontal line for x + y = 14.
Draw a diagonal line with negative slope for x + 2y = 20.
Shade the region below the diagonal line and to the left of the horizontal line.
The shaded region represents the feasible region that satisfies both inequalities. We also know that x ≤ 4 since a maximum of 4 coins are nickels.
One possible solution that lies in the shaded region and satisfies the constraint x ≤ 4 is (x, y) = (2, 12). This means Keshawn has 2 nickels and 12 dimes. We can check that this solution satisfies both inequalities:
2 + 12 = 14 (maximum number of coins)
0.05(2) + 0.1(12) = 1.2 ≥ 1 (minimum value of the coins)
Therefore, one possible solution is Keshawn has 2 nickels and 12 dimes.

Merisa spent 3/4 of her money on a dictionary. She spent 1/2 of the remainder on a calculator. The dictionary cost $30 more than the calculator. How much did the dictionary cost?
Step-by-step explanation:
she has x money at the beginning.
(3/4)x = dictionary
the remainder is (1/4)x.
1/2 of that (1/4 × 1/2 = 1/8) is the calculator.
that means she has (1/4)x - (1/8)x = (1/8)x left.
the dictionary is $30 more than the calculator.
so,
(3/4)x = (1/8)x + 30
(6/8)x = (1/8)x + 30
(5/8)x = 30
5x = 240
x = 240/5 = $48
so, the dictionary cost

Determine whether the equation is true or false.
By answering the presented question, we may conclude that When x equals 7, the equation holds true. As a result, "True" is the correct response.
What is equation?A math equation is a technique that links two assertions and denotes equivalence using the equals sign (=). In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For example, in the equation 3x + 5 = 14, the equal sign separates the numbers 3x + 5 and 14. A mathematical formula may be used to understand the link between the two phrases written on either side of a letter. The logo and the programmed are usually interchangeable. As an example, 2x - 4 equals 2.
The image's equation is:
2x + 4 = 18
We must solve for x to discover if the equation is true or untrue.
When we subtract 4 from both sides, we get:
2x = 14
When we divide both sides by 2, we get:
x = 7
When x equals 7, the equation holds true. As a result, "True" is the correct response.

The two solutions to the given quadratic equation are x = (a+b + √(a2 - 6ab + 8b2))/(2(a-b)) and x = (a+b - √(a2 - 6ab + 8b2))/(2(a-b)).
The general form of a quadratic equation is ax2 + bx + c = 0. To solve this equation, we need to use the Quadratic Formula. The Quadratic Formula is [tex]x = [-b ± √(b2 - 4ac)]/ 2a[/tex].
We can plug the values for a, b, and c into this equation. For this equation, a = (a-b), b = -(a+b), and c = 2b.
Therefore, using the Quadratic Formula, we get [tex]x = [-(-(a+b)) ± √((-(a+b))2 - 4(a-b)(2b))]/ 2(a-b)[/tex].
Simplifying this, we get [tex]x = [a+b ± √(a2 + 2ab - 4ab - 8b2)]/(2(a-b))[/tex].
Finally, we can solve for the two values of x by computing the two cases. In the first case, we add the square root, and in the second case, we subtract the square root. This gives us the two solutions [tex]x = [(a+b + √(a2 - 6ab + 8b2))/(2(a-b))][/tex] and [tex]x = [(a+b - √(a2 - 6ab + 8b2))/(2(a-b))][/tex].

Fatal Accidents The American Automobile Association (AAA) reports that of car accidents, 56% are caused by aggressive driving. If 3 accidents are chosen at random, find the probability for the following. Please round the final answers to 2 or 3 decimal places. Part 1 of 3 (a) None are caused by aggressive driving. P (none are caused by aggressive driving) = _____
Answer : The probability that none of the 3 accidents are caused by aggressive driving is 0.085, according to the American Automobile Association (AAA).
The probability of an accident being caused by aggressive driving is 56%, or 0.56. Therefore, the probability of an accident NOT being caused by aggressive driving is 1 - 0.56 = 0.44. Since the accidents are chosen at random, we can assume that they are independent events. Therefore, we can multiply the probabilities together to find the overall probability.
For part 1, we want to find the probability that none of the 3 accidents are caused by aggressive driving. This means we want the probability of an accident not being caused by aggressive driving (0.44) to happen 3 times in a row:
P(none are caused by aggressive driving) = 0.44 * 0.44 * 0.44 = 0.085184
Round to 3 decimal places:
P(none are caused by aggressive driving) = 0.085

The expanded form that can be used to factor the function is 12x² - 18x + 10x - 15.
option C,
What is the factorization of the equation?
To factor 12x² - 8x - 15 by grouping, we need to split the middle term -8x into two terms whose sum is -8x and whose product is -180 (the product of 12 and -15).
We can do this by splitting -8x into -18x and +10x:
12x² - 18x + 10x - 15
Now, we can group the first two terms together and the last two terms together, and factor out the greatest common factor from each group:
6x(2x - 3) + 5(2x - 3)
Notice that we have a common factor of (2x - 3) in both groups, so we can factor it out:
(2x - 3)(6x + 5)

Therefore , the solution of the given problem of average comes out to be the average price of a pizza in 2000 was about $9 (or half of $18).
Explain average.An organised collection's median value is the precise value that makes up the collection's mean. In this case, the ratio between the lowest and highest 50% of the data is a normal but rather probability measure. When finding the middle and mode, a variety of algorithms can be applied in order to identify any unusual or even amounts of values.
Here,
By dividing 72 by the interest rate, we can calculate how many years it will take an investment to double in value at a specific interest rate. This is known as the law of 72. In this instance
With an inflation rate of 3.25 percent, it takes roughly how many years for the price of a pizza to double as a result of inflation:
72 / 3.25 = 22.15 years
In light of this, we can calculate that a pizza cost $9 (half of $18) roughly 22 years ago, which corresponds to the following year:
2022 - 22 ≈ 2000

A cabinet maker can build a kitchen island in 11 hours. If the cabinet maker's apprentice helps, they can construct the kitchen island in 8 hours. How long would it take apprentice to complete a kitchen island alone?
It would take the apprentice alone 11 hours to complete a kitchen island, the same amount of time it took the cabinet maker and apprentice together.
When the cabinet maker and apprentice work together, they are able to complete the kitchen island in 8 hours. This implies that the apprentice is able to do their portion of the work in 3 hours, while the cabinet maker does their portion in 8 hours. Therefore, if the apprentice were to work on the kitchen island alone, it would take them 11 hours to complete it, the same amount of time it took the cabinet maker and apprentice together. This is because the apprentice does not have the same level of experience and expertise as the cabinet maker, so they are not able to complete the same amount of work in the same amount of time as the cabinet maker. The cabinet maker is able to work faster and more efficiently, which is why they are able to complete the kitchen island in 8 hours, while the apprentice would need 11 hours to complete the same task.

It’s a solve for why problem pls help me
The exponential function in the given table is:
y = 0.02*(1/2)^x
How to get the function in the table?This seems to be an exponential function of the form:
y = a*b^x
Using the points in the table we can try to find the values of a and b.
for the first point we can write:
0.02 = a*b^0
0.02 = a
Then the function is:
y = 0.02*b^x
Now the second point, (1, 0.01), replacing that we will get:
0.01 = 0.02*b^1
0.01 = 0.02*b
0.01/0.02 = b
1/2 = b
The function is:
y = 0.02*(1/2)^x

A softball team has 20 players. How many 9 player batting orders are possible?
There are 184,756 possible 9 player batting orders for a softball team with 20 players.
The formula to calculate the combination number of possible batting orders for a team with n players is n!/(n-r)! where n = the total number of players, and r = the number of players in the batting order. Therefore, for a softball team with 20 players, the number of possible 9 player batting orders is 20!/(20-9)! = 184,756.
20! = 20 × 19 × 18 × 17 × 16 × 15 × 14 × 13 × 12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
(20-9)! = (20 - 9) × (19 - 9) × (18 - 9) × (17 - 9) × (16 - 9) × (15 - 9) × (14 - 9) × (13 - 9) × (12 - 9) × (11 - 9) × (10 - 9) × (9 - 9)
20!/(20-9)! = 184,756
Therefore, there are 184,756 possible 9 player batting orders for a softball team with 20 players.

Therefore, the measure of angle 1 is 40°.
What does a mathematical angle mean?Two rays (half-lines) that share a terminal are combined to form an angle. In contrast, the rays are variously referred to as the angle's legs and its arms, with the latter serving as the angle's vertex.
The measure of an inscribed angle is half the measure of its intercepted arc. Therefore, we can use this property to find the measure of angle 1.
If mAB = 80°, then arc AB is also 80° because an inscribed angle intercepts an arc with the same measure as the angle. Therefore, the measure of arc AB is 80°.
Since angle 1 is an inscribed angle that intercepts arc AB, its measure is half the measure of arc AB. Therefore, we can find the measure of angle 1 as follows:
m∠1 = (1/2) x m arc AB
m∠1 = (1/2) x 80°
m∠1 = 40°
Therefore, the measure of angle 1 is 40°.
