find x
Answer:
D
Step-by-step explanation:
the measure of a secant- tangent angle is half the difference of the intercepted arcs, then
[tex]\frac{1}{2}[/tex] (154 - (12x + 2) ) = 6x + 4 ( multiply both sides by 2 to clear the fraction )
154 - 12x - 2 = 12x + 8 , that is
152 - 12x = 12x + 8 ( subtract 12x from both sides )
152 - 24x = 8 ( subtract 152 from both sides )
- 24x = - 144 ( divide both sides by - 24 )
x = 6

clockwise about the origin and then translated
2 units left and 3 units down to form A'B'C'D'.
What is the length, in units, of line segment A'B'
if AB was 4 units?
Rotation involves moving the rectangle ABCD around a fixed point
The length of side A'B' is 4 units, if AB was 4 units
How to determine the length of A'B'From the question, we have the following transformations

Answer:
B = 48°
b = 29.7
c = 39.1
Step-by-step explanation:
You have made a Mistake which is C = 102° Not 120°
So, Lets begin with the Problem
Since the Sum of Interior Angles of the Triangle = 180 °
Then A+B+C=180
Then 30+B+102=180
Then B+132=180
Subtract 132 from Both sides
B = 180 - 132 = 48°
Applying Law of Sines
[tex]\frac{a}{sinA} =\frac{b}{sinB}=\frac{c}{sinC}[/tex]
by substituting
[tex]\frac{20}{sin30} =\frac{b}{sin48}=\frac{c}{sin102}[/tex]
Then [tex]b=\frac{20sin48}{sin30} =29.7[/tex]
Then [tex]c=\frac{20sin102}{sin30} =39.1[/tex]
3 A scientist takes four random samples of a population of 700 trees. Each sample is
the same size. The first sample indicates that 30% of the trees are oak, while the
second sample indicates that only 15% of the trees are oak. The third sample
indicates that 26% of the trees are oak. The fourth sample indicates that 29% of
the trees are oak. Based on the data, about how many of the 700 trees are oak?
Using proportions, it is found that about 175 trees are oak.
What is a proportion?A proportion is a fraction of a total amount.
For the four samples, the proportions are: {0.3, 0.15, 0.26, 0.29}.
Hence, the mean proportion is given by:
M = (0.3 + 0.15 + 0.26 + 0.29)/4 = 0.25
Out of 700 trees:
700 x 0.25 = 175.
About 175 trees are oak.

find the equation of the line that passes through the point (3,5) and is parallel to the equation of the line y=2×-5
Answer:
y=2x-1
Step-by-step explanation:
Since it is parallel to y=2x-5, they have the same slope of 2.
Now you're going to plug the point and slope into the following equation: y-(y value of point) = slope ×(x-(x value of point))
y-5= 2 (x-3)
Now you simplify:
y-5=2x -6
y=2x-1

What is a graph?A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.
here, we have,
A.) A symmetric graph is a graph in which the left half of the graph looks like the mirror image of the right half of the graph. Since the graph has no symmetry it is not a symmetric graph.
B.) Skewness is a distortion or asymmetry in a set of data that deviates from the symmetrical bell curve, or normal distribution. The curve is said to be skewed if it is displaced to the left or right. As we can see that the shape of the graph is the left tilted bell shape.
C.) A constant graph is a graph in which the value of each bar lies on the same horizontal value. Since the shape of the graph is not a horizontal line, it is not a constant shape graph.
D.) When a graph has Peak and Valleys in a graph, the values of the graph are different from each other, therefore, forming peaks and valleys in a graph, which looks like a spline. Since the value of the graph is decreasing towards the right side of the graph. Therefore, the graph of the shape is not of a peak and valley.
Thus, the shape of this graph is best described as skewed.

At a fabric store, fabrics are sold by the yard. A dressmaker spent $36.35 on 4.25 yards of silk and cotton fabrics for a dress. Silk is $16.90 per yard and cotton is $4 per yard.
Let 'x' represent the number of yards of silk and 'y' represent the number of yards of cotton.
Here is a system of equations that represent the constraints in the situation.
x+y=4.25
16.90x+4y=36.35
Find the solution to the system of equations. You may use any method you want, but you must explain your reasoning and methods fully.
Answer:
Step-by-step explanation:
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.
x + y = 4.25 equation 1
16.90x + 4y = 36.25 equation 2
where:
x = yards of silk bought
y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards
In order to determine the value of y, substitute for x in equation 1
1.49 + y = 4.25
y = 4.25 - 1.49
y = 2.76 yards
Answer:
Step-by-step explanation:
The yards of silk bought is 1.49 yards and the yard of cotton bought is 2.76 yards.
The two equations are known as simultaneous equation. They would be solved using elimination method.

y = yards of cotton bought
In order to determine the value of x, multiply equation 1 by 4.
4x + 4y = 17 equation 3
Subtract equation 3 from 2
19.25 = 12.90x
Divide both sides of the equation by 12.90
x = 1.49 yards

Juan is clearing land in the shape of a circle to plant a new tree. The diameter of the space he needs to clear is 52 inches. By midday, he has cleared a sector of the land cut off by a central angle of 140 . What is the arc length and the area of land he has cleared by midday?
The central angle of 140 degrees illustrates the degree measure of the arc
The arc length cleared is 63.54 inches and the area of the land cleared is 826.00 square inches
How to determine the arc lengthThe given parameters are:
Central angle = 140 degrees
Diameter = 52 inches
The length of the arc is then calculated s:
[tex]L = \frac{\theta}{360} * \pi d[/tex]
Substitute known values in the equation
[tex]L = \frac{140}{360} * 3.142 * 52[/tex]
Evaluate the products
[tex]L = \frac{22873.76}{360}[/tex]
Evaluate the quotient
[tex]L = 63.54[/tex]
Hence, the arc length cleared is 63.54 inches
How to determine the area of the land clearedThe area is calculated s:
[tex]A = \frac{\theta}{360} * \pi (d/2)^2[/tex]
Substitute known values in the equation
[tex]A = \frac{140}{360} * 3.142 * (52/2)^2[/tex]
Evaluate the products
[tex]A = \frac{297358.88}{360}[/tex]
Evaluate the quotient
[tex]A = 826.00[/tex]
Hence, the area of the land cleared is 826.00 square inches

Mr. Ingle purchased a Prius for $42,500. If the car depreciates at a rate of 10%, what is
the value of the car after 7 years?
Based on the cost of Mr. Ingle's car and the depreciation rate, the value after 7 years will be $20,327.62.
What would be the value after 7 years?This can be found by the formula:
= Cost of car x ( 1 - depreciation rate) ^ number of years given
Solving gives:
= 42,500 x (1 - 10%)⁷
= 42,500 x 0.4782969
= $20,327.62
