Angle 6, Angle 16 and Angle 11 are not congruent.
We need to check ∠5 is not equal to which angle from the figure.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Here,
Angle 5 = Angle 2 (Vertically opposite angles)
Angle 5 = Angle 7 (corresponding angles are equal)
Angle 5 = Angle 13 (corresponding angles are equal)
Therefore, Angle 6, Angle 16 and Angle 11 are not congruent.

Answer:
B) Angle 6
C) Angle 16
E) Angle 11
Step-by-step explanation:
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Corresponding Angles Theorem
When a straight line intersects two parallel straight lines, the angles in the same relative position are congruent.
According to the corresponding angles theorem:
∠5 = ∠13 = ∠7 = ∠15∠2 = ∠10 = ∠4 = ∠12According to the vertical angles theorem:
∠5 = ∠2Therefore:
∠5 = ∠2 = ∠4 = ∠7 = ∠10 = ∠12 = ∠13 = ∠15As angle 5 is not a right angle, the angles that angle 5 is not equal to are:

The given figure is a Rhombus hence the last diagram is correct.
In planar Euclidean geometry, a rhombus—also known as a rhombi or rhombus—is a quadrilateral having four sides of equal length.
A quadrilateral with equally sized sides is referred to as a "equilateral quadrilateral." While the name "diamond" is usually used to refer to a rhombus with a 60° angle because it resembles the projection of an octahedral diamond from the playing card's diamond suitThe term "lozenge" is occasionally used to specifically refer to a rhombus with a 45° angle.Every single rhombus is a unique example of a parallelogram and a kite, and it is straightforward (does not self-intersect). A right-angled rhombus is a square.The given figure is a rhombus. All the sides are equal but the angles are not 90°. Hence its is not a square or a rectangle.

Derek filled the pitcher with 8 fluid ounces of lemonade. What was the percent error if the actual measurement was 10 fluid ounces?
Answer: 80%
Step-by-step explanation:
To find percent error all you have to do is divide the estimate by the actual then multiply it by 100
8/10×100=80%
The percent error of the actual measurement of 10 fluid ounces is 25%.
Percent error:
Percent error means the difference between the exact or known value of something and its approximate or actual value, in percentage form.
The formula to calculate the percent id defined as
δ = |(A - E)/E| x 100%
Where
δ = percent error
A = actual value observed
E = expected value
Given,
Derek filled the pitcher with 8 fluid ounces of lemonade.
Here we need to find the percent error if the actual measurement was 10 fluid ounces.
According to the percent error formula, the actual value in the given question is 10 and the expected value is 8.
Then we have to apply the value on the formula, then we get,
Percent error = [(10 - 8)/8] x 100%
Percent error = [2/8] x 100%
Percent error = 0.25 x 100%
Therefore, the percent error in the given situation is 25%.

Step-by-step explanation:
rearrange this equation y – 7=3(x−4) into this Ax+By = C
its pretty simple if you think about it :)
firstly, lets multiply the 3 with x - 4
y - 7 = 3x -12
we are going to bring the 3x to the right side to make the arrangement possible

If Justin bought a calculator and a binder that were both 15% off the original price. The original price of the binder was $6.20. Justin spent a total of $107.27. Then $120 the original price of the calculator
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100.
Let,
x be the original price of the calculator
y be the original price of the binder
we know that
15%=15/100=0.15
(x+y)(1-0.15)=$107.27
(x+y)(0.85)=$107.27....(1)
y=6.20....(2)
substitute the value of y in the equation A and solve for x
(x+6.20)(0.85)=107.27
(x+6.20)=107.27/0.85
x=107.27/0.85-6.20
x=126.20-6.20

walks 1.65 more meters past the mirror, so that when he turns around and looks
down at the mirror, he can see the top of the school clearly marked in the X. His
partner measures the distance from his eyes to the ground to be 1.55 meters. How tall
is the school? Round your answer to the nearest hundredth of a meter.
Answer:

A study on students drinking habits wants to determine the true average number of alcoholic drinks all uf graduate students have in a one week period. We know from preliminary studies that the standard deviation is around 1. 8. How many students should be sampled to be within 0. 25 drink of population mean with 95% probability?.
The number of the students should be sampled to be within 0.25 alcoholic drinks of population mean with 95% probability is 62.
What is termed as the Margin of error?The margin of error measures the degree of uncertainty in the parameter estimates of parameter results.The reliability of a estimates decreases as the margin of sample error increases.α is the result of subtracting one from confidence interval as well as dividing by two.
α = (1 - 0.95) ÷ 2 = 0.25
Find z in the Z-table because z does have a p-value of 1 - α.
As a result, the p-value of z is (1 - 0.025) = 0.975.
Thus, z = 1.96
Now find M as;
M = z × (σ ÷ √n)
In which,
n is the sample size σ = population standard deviation.When M = 1,
The standard deviation, in accordance with the question, is approximately 1.
σ = 1
M = z × (σ ÷ √n)
0. 25 = 1.96 × (1 ÷ √n)
√n = 1.96 × (1 ÷ √n)
Squaring both sides,
(√n)² = ((1.96 × 1) ÷ 0.25)²
n = (7.84)²
n = 61.4656
n ≈ 62
Thus, the number of the students should be sampled to be within 0. 25 alcoholic drink of population mean with 95% probability is 62.

An insurance agent is paid a salary of 200 and a commission of 3% on all sales over 2000 per month. If his total income in a particular month was 530 what was the amount of his sales for that month
The amount of the insurance agent's sales for the month is 11,000.
What is the amount of sales?The total income can be modelled as a linear equation. A linear equation is an equation that has one variable that is raised to the power of one. The form of a linear equation is:
y = mx + b
Where:
m = slope b = intercept530 = base salary + (percentage x value of sales over 2000)
530 = 200 + 3% x s
530 = 200 + 0.03s
530 - 200 = 0.03s
