Let x represent measure of angle 1.
We have been given that measure of angle 3 is six more than twice the measure of angle 1. So measure of angle 3 would be .
We are also told that measure of angle 2 is 27 less than measure of angle 3, so measure of angle 2 would be .
We have been given that angle 1, angle 2 and angle 3 form a straight line, so the sum of angles 1, 2 and 3 would be 180 degrees.
Upon substituting the expressions for measure of angles, we will get:
Now, we will combine like terms.
The measure of angle 2 would be .
Therefore, the measure of angle 2 is 57 degrees.

Answers
Let angle D be an acute angle such that D=0. 33. The measure of angle D is 70.7 degree.
Acute Angle:
An angle is formed when two rays meet at a vertex. If this angle is less than 90°, it is called an acute angle. In the image below, the angle formed between "Ray 1" and "Ray 2" is acute. Bisecting a right angle also creates two acute angles.
Inverse Cosine :
Inverse cosine is the important inverse trigonometric function. Mathematically, it is written cos-1(x) and is the inverse of the trigonometric cosine cos(x). Note that arc cosine is not the reciprocal of cos x. There are six inverse trigonometric functions like sin-1x, cos-1x, tan-1x, csc-1x, sec-1x, cot-1x. The arc cosine is used to determine angular measurements from the trigonometric ratio cos x values.
According to the question:
To approximate the measure of angle D, we will need to use the inverse cosine function on our calculator. All calculators vary, so I am not sure where you would find the button for it on your calculator. However, I know many calculators have it so you click the second button, then cos
cos(D) = 0.33
⇒ D = cos^-1 (0.33)

Write an equation of the line that passes through (-4, 2) and is perpendicular to the line y=2/7x-8
Answers
The equation of the perpendicular line is y = -7/2(x + 5) + 2
How to determine the perpendicular line equation?From the question, we have the following parameters that can be used in our computation:
y=2/7x-8
Also, from the question;
We have the following points
Point = (-4, 2) i.e. (x, y) = (-4, 2)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = 2/7
This means that the slope is 2/7
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is -7/2
The equation of the line is then calculated as
y = m(x - x₁) +y₁
Where
m = -7/2
(x₁, y₁) = (-4, 2)
So, we have
y = -7/2(x + 5) + 2
Hence, the line has an equation of y = -7/2(x + 5) + 2

What is the cartesian plane?When two parallel lines intersect, a two-dimensional coordinate plane called the cartesian plane is created. The horizontal line is the X-axis, while the vertical line is the Y-axis. If the sign of x is positive, the coordinate point (x, y) in the Cartesian plane indicates that the point is on the right of the origin; otherwise, it indicates that the position is on the left of the origin.
Given a line L,
and the equation of a line is y = 1
actual equation of line is ax + by +c = 0
equation of line is 0x + y - 1 = 0
here a = 0, b = 1 and c = -1
and point T(-1, -7)
distance between line and the point is d = [tex]\frac{|ax_1 + by_1 + c|}{\sqrt{a^2 + b^2} }[/tex]
x₁ = -1, y₁ = -7
|ax₁ + by₁ + c| = |0(-1) + 1(-7) +(-1)|
|ax₁ + by₁ + c| = 8
√(a² + b²) = √(0² + (1)²) = 1
distance between line and the point is d = 8/1 = 8 units

whats the intercepts of 2x+y=1 and x-2y=8
Answers
Answer:
Step-by-step explanation:
I will assume you want the y-axis intercepts
arrange each equation into the form y = mx + b <==b is y-axis intercept
2x+y =1
y = -2x+1 <==== y axis intercept = 1
x -2y = 8
2y = x-8
y = 1/2x -4 <==== - 4 is the y axis intercept
Another way to find the y-axis intercept is to realize this occurs when x = 0
put x = 0 into the equations to find the intercept value
2x+y =1
2(0) + y = 1
y =1 <=====intercept
x-2y = 8
0 - 2y = 8
y = -4 <=====intercept
To find the where the two lines intersect, equate them
-2x+1 = 1/2x-4
5 = 2.5x
x = 2 then y = -2x+1 = -3 point of intersection (2,-3)
Suppose a supermarket wants to sell eggs individually. Is there a price the supermarket can charge per egg that is between the prices per egg for the two different sized cartons?
Answers
The maximum price per egg that the supermarket may charge is $0.245 per egg, which is the difference between the pricing per egg for the 2 distinct cartons.
What do you meant by the term unitary method?The unitary approach involves calculating the price of a specific unit, from which we can calculate the values of the necessary number of units.The answer to the query is
The following details are available to us:
A carton of 12 eggs costs $3.00.18 eggs in such a different carton cost $4.32.We'll first calculate the cost per egg for each of the two different-sized cartons in order to determine the cost per egg that lies between the two costs.
We are aware that the cost of one product is determined by dividing the total cost by the quantity of products.
12 eggs cost in a carton = $3.001 eggs cost = $ (3.00/12) = $0.2412 eggs cost in a second carton = $4.321 eggs cost = $(4.32/18) = $0.24The price of an egg between 0.24 as well as 0.25 must now be determined.
Note that there is a 0.01 difference between the two fees.
To precisely determine the middle charge, we will split it by two:
0.01/2 = 0.005
This can be added to $0.24 or subtracted from $0.25.
$0.24 + $0.005 = $0.245
So, $0.245 is the maximum price the supermarket can charge per egg.

2 1/5 x 2 2/3 fravction
Answers
To multiply two mixed numbers, you can convert them to improper fractions and then multiply the numerators and denominators separately.
2 1/5 can be written as (2 x 5 + 1) / 5 = 11/5
2 2/3 can be written as (2 x 3 + 2) / 3 = 8/3
So the product of 2 1/5 x 2 2/3 is (11/5) * (8/3) = 88/15 which is equivalent to 5 8/15 or 5.533 repeating (if you want to express it as decimal)
You can simplify 88/15 by dividing both numerator and denominator by the greatest common divisor (GCD) which is 1 in this case, so the final result is 88/15.
How many solutions the linear equation 2x y 10 has?
Answers
The linear equation [ ( 2x PLUS y ) EQUALS 10 ] has only one solution.
A linear equation is an algebraic equation having the form y=mx+b, involving only a constant and a first-order (linear) term, where b is the y-intercept and m is the slope. Occasionally, the above is called a 'linear equation of two variables,' where x and y are the variables.
Now solve the given linear equation which is:
[ ( 2x + y ) = 10 ]
Now solve this equation in order to determine the number of solutions it has,
( 2x + y ) = 10
( 2x + (10 - 2x)) = 10
( 2x + 10 - 2x) = 10
( 2x + 10 - 2x) = 10
(10) = (10)
Since 10 = 10 is correct, therefore, the equation ( 2x + y ) = 10 has only one solution.

enlarge shape q by a scale factor of -1/2 around the centre point (0,0
Answers
The new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
A scale factor of -1/2 around the center point (0,0) would reflect the shape across the origin and also shrink it by a factor of 1/2.
The transformation can be represented by the matrix:
[-1/2 0]
[ 0 -1/2]
This matrix would be applied to the coordinates of each point in the shape to obtain the new coordinates of the transformed shape.
So, if a point in the shape had coordinates (x, y), the new coordinates of the point in the transformed shape would be (-1/2x, -1/2y).

What is the coordinate plane?The Cartesian coordinate system on a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates.
These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.
A graph having one x-axis and one y-axis is referred to as a cartesian plane (also known as an X-Y graph).
The orientation of these two axes is perpendicular.
The graph's exact center is marked by the origin (O).

How do you find the center of dilation with a compass?
Answers
To find the center of dilation,We'll fix our compass to a distance that is closer to the overall distance but still greater than halfway between vertex L and point C. Start with the compass's point on vertex L while maintaining the same distance, and then draw a curve that intersects the line connecting L and C.
What is Centre of dilation?Centre of dilation of an image in mathematics refers to a change that results in an image with the same shape but a different size, either larger or smaller. A dilation can only be built with two bits of information.
An operation that moves, flips, or otherwise alters a figure to produce a new figure is called a transformation. Rigid transformations maintain size, whereas non-rigid transformations do not. A dilatation enlarges or reduces a figure while maintaining its original shape. To put it another way, the dilatation resembles the original. Every dilatation has a scale factor and a centre. The scale factor indicates how much the figure stretches or contracts, and the centre serves as the point of reference for the dilation (much like the vanishing point in a perspective drawing). A scale factor is usually identified by a label and is never zero. Additionally, the dilatation would be if the original figure were labelled, for example.
The point from which the image is dilated is known as the centre of dilatation (or point of dilation).

many cubic yards of each component are needed.
Answers
The number of cubic yards of each component needed are 3.99 cubic yards of cement, 7.97 cubic yards of sand and 15.94 cubic yards of gravel
How to determine how many cubic yards of each component are needed?
Ratio is used to compare two or more quantities. It is used to indicate how big or small a quantity is when compared to another
Since a total of 18.6 cu yd of concrete is required and the total amount of these components must be 1½ times the volume of concrete needed. We can say:
total amount of these components = 1½ × 18.6 cu yd = 27.9 cu yd
Also, since the ratio of cement to sand to gravel for this application is 1:2:4. We have:
Total share = 1 + 2 + 4 = 7
cement = 1/7 × 27.9 = 3.99 cubic yards
sand = 2/7 × 27.9 = 7.97 cubic yards
gravel = 4/7 × 27.9 = 15.94 cubic yards

In an independent random sample of 300 non-smokers, 159 said they had consumed alcohol in the past week. If P, is the proportion of smokers in the population who have had a drink in the past week and Po is the corresponding proportion of non-smokers, then a test of the hypotheses H P, -P = 0 against the two-sided alternative produces a test statistic of := 3.07 and a P-value of 0.002. If we had instead analyzed these results with a chi-square test of homogeneity, which of the following would be the test statistic and P-value?
a. 7-9.42, P-value = 0.002
b. 7-9.42, P-value - 0.004
c. - 3.07, P-value = 0.004
Answers
The Correct answer is option a. 7-9.42, P-value = 0.002 which is derived based on the given data about alcohol consumption.
The chi-square test of homogeneity is a statistical test used to determine whether there is a significant difference between the observed frequencies of two categorical variables.
In this case, the test statistic would be the chi-square value calculated using the observed frequencies of alcohol consumption in the sample of smokers and non-smokers, and the P-value would be the probability of obtaining a chi-square value as extreme or more extreme than the calculated value under the assumption that the null hypothesis is true (i.e. no difference in alcohol consumption between smokers and non-smokers).
In this case, the test statistic would be 7.942 and the P-value would be 0.002 which implies that there is a significant difference in alcohol consumption between smokers and non-smokers.
