We have the supplementary angles.
The sum of the measures of the two Supplementary Angles is 180°.
Therefore we have the equation:
13x - 2 + 39 = 180
13x + 37 = 180 subtract 37 from both sides
13x = 143 divide both sides by 13
x = 11

Wangari plants trees at a rate of 4 trees per hour. The equation relating the number of trees planted (p) to the time spent planting (h) is p = 4h.
Equation for Trees Planted by Wangari
Wangari plants trees at a constant rate, which means we can write a linear relationship between the number of trees planted (p) and the time spent planting them (h in hours). From the problem, we know:12 trees are planted in 3 hoursFirst, let's find the rate of planting trees per hour. We do this by dividing the number of trees by the number of hours:Rate = Number of Trees / TimeRate = 12 trees / 3 hours = 4 trees/hourThis tells us that Wangari plants 4 trees every hour. To write an equation that relates the number of trees (p) to the number of hours (h), we use the rate we found:
p = 4hHere, p represents the number of trees planted and h represents the number of hours spent planting.

Forrest Lumber purchased a table saw for $735. After 2 years the saw had a depreciated value of $525. What is the amount of yearly depreciation? A. $105 B. $210 C. $90 D. $120
Answers
Final answer:
The amount of yearly depreciation for the table saw is calculated by subtracting the depreciated value from the original cost and dividing by the number of years, resulting in an amount of $105 per year.
Explanation:
The question involves calculating yearly depreciation of an asset, which is a common topic in accounting and finance sections of high school mathematics or business studies.
To find the amount of yearly depreciation, we subtract the end value of the asset after depreciation from its original cost and then divide by the number of years over which the depreciation occurred. In this case, we have:
Original cost of the saw = $735
Depreciated value after 2 years = $525
Depreciation over 2 years = Original cost - Depreciated value
Depreciation over 2 years = $735 - $525 = $210
Yearly depreciation = Depreciation over 2 years ÷ Number of years
Yearly depreciation = $210 ÷ 2 = $105
Therefore, the yearly depreciation of the table saw is $105, which corresponds to option A.

Answers
Answer: There are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.
There are 5 red fabrics and 11 gold fabrics that would be used for each curtain.
Step-by-step explanation:
Since we have given that
Number of yards of red fabric purchased by Jane = 50
Number of yards of gold fabric purchased by Jane = 110
We need to find the largest number of curtains she can make if she wants all the curtains to be exactly the same length.
For this we will find H.C.F. of 50 and 110.
Factors of 50 = 1, 2, 5, 10, 25, 50.
Factors of 110 = 1, 2, 5, 10, 11, 22, 55, 110.
So, Highest common factor of 50 and 110 is 10.
So, there are 10 largest number of curtains she can make if she wants all the curtains to be exactly the same length.
Number of yards of red fabric is given by
[tex]\frac{50}{10}=5[/tex]
Number of yards of gold fabric is given by
[tex]\frac{110}{10}=11[/tex]
Hence, there are 5 red fabrics and 11 gold fabrics that would be used for each curtain.

It is given that 1 sq. mile is equal to 640 acres.
Let's convert 190 million acres to sq. miles.
[tex]190,000,000*\frac{1Sq.Mi.}{640Acres}=296,875Sq.Mi.[/tex]
Taking Wyoming as a rectangle, we can find the area of Wyoming by multiplying length (352 miles) with width (278 miles).
Area of Wyoming is [tex]352*278=97,856[/tex]
To find the number of Whyoming's in total area of national forests, we divide the area of national forests (in sq. mi.) by the area of Wyoming ( in sq. mi.):

Put the numbers in the data set in order from smallest to largest:
44, 45, 45, 47, 49, 50, 50, 51, 55, 55, 55, 56
The smallest number is 44, the largest is 56, so the outside lines need to be above those numbers.
Both A and B have that.
Now find the median ( the average of the middle two numbers)
The middle two numbers from the list are 50 and 50 so the median would be (50 +50) /2 = 100/2 = 50
The middle line inside the rectangle needs to be above 50.
This makes the answer A.
Which sequence of transformation will not result in a figure that is congruent to the original figure?
A) a rotation of 270° counter clockwise about the origin followed by translation of eight units to the right
B) A reflection over the Y axis followed by a rotation of 180° about the origin
C) a dilation with a scale factor of four followed by reflection over the x-axis
D) A reflection over the Y axis followed by a translation of 3 units to the left and 2 units to the right
Answers
Answer:
The correct option is C.
Step-by-step explanation:
Two figures are congruent if their corresponding sides are congruent.
We know that, reflection, rotation and translation are rigid transformation. It means the size and shape of image and preimage are same. We can say that in rigid transformation, the image and preimage are congruent.
Dilation is not a rigid transformation. It represents enlargement and compression.
If scale factor |k|>1, then it represent enlargement. If scale factor |k|<1, then it represent compression.
In option C, the scale factor is 4. It means the sides of image are 4 times of the preimage.
Therefore option C is correct and the resultant figure of option C is not congruent to the original figure.

x=3
2+3i
Answers
Answer:
p(x) = x³ - 7x² + 25x - 39
Step-by-step explanation:
complex roots occur as conjugate pairs, thus
2 + 3i is a root then 2 - 3i is also a root
given x = 3, x = 2 +3i, x = 2 - 3i are roots, then
(x - 3), (x - (2 + 3i))(x - (2 - 3i)) are the factors and
p(x) = a(x - 3)(x - 2 - 3i)(x - 2 + 3i) ← a is a multiplier
let a = 1
p(x) = (x - 3)((x - 2)² - 9i²)
= (x - 3)(x² - 4x + 4 + 9) → [ i² = - 1 ]
= (x - 3)(x² - 4x + 13)
= x³ - 4x² + 13x - 3x² + 12x - 39
= x³ - 7x² + 25x - 39

keith and michelle went out to dinner. the total cost of the meal,including the tip,came to $53.70. if the combined tip came out yo 9.60,and each friend spent and equal amouny,how much did each friend pay not including the tip?
Answers
Answer:
23.45
5
Step-by-step explanation:
53.70-9.60 is 46.90
46.90 divided by 2 is 23.45
Each friend paid $22.05 before the tip.
Keith and Michelle's dinner bill is a mathematics problem that can be solved by subtracting the tip from the total bill to find the cost of the meal alone and then dividing that amount by two to find out how much each friend has to pay without the tip.
First, we subtract the combined tip of $9.60 from the total cost of the meal, which was $53.70. This gives us the cost of the meal before the tip was added:
$53.70 - $9.60 = $44.10
Next, since Keith and Michelle spent an equal amount, we divide the cost of the meal by 2 to find out how much each friend pays:
$44.10 / 2 = $22.05
So, each friend paid $22.05 for the meal before adding in the tip.
Gretchen makes pillows using 1 5/8 yards of fabric per pillow. She has 8 1/4 yards of fabric. What is the greatest number of pillows Gretchen can make?
a( 4 , b(5 , c(6 , or d(8
Answers
Gretchen can make 5 pillows with the fabric she has.
Define fractionA fraction is a numerical quantity that represents a part of a whole. It consists of two numbers separated by a line, with the number on top called the numerator and the number on the bottom called the denominator
1 5/8 yards of fabric = 13/8 yards of fabric
8 1/4 yards of fabric = 33/4 yards of fabric
Number of pillows = (Total fabric) ÷ (Fabric per pillow)
Number of pillows = (33/4 yards of fabric) ÷ (13/8 yards of fabric per pillow)
Number of pillows = (33/4 yards of fabric) × (8/13 pillows per yard of fabric)
Number of pillows =5.076≈5
Hence, the greatest number of pillows she can make is 5, which corresponds to option (a) in the multiple choice list.

=5/-7
= -5/7
We can use the point slope form of the equation to find the equation of the line
y-y1 = m(x-x1)
y--7 = -5/7 (x--1)
y+7 = -5/7 (x+1)
Distribute the -5/7
y+7 = -5/7 x - 5/7
Subtract 7 from each side
y+7-7= -5/7 x -5/7 -7
y = -5/7x -5/7 -7
Get a common denominator of 7
y = -5/7x -5/7 -49/7
y = -5/7x -54/7
This is in the form
y= mx+b, where b is the y intercept
The y intercept is -54/7
What is the definition of similar figures
Answers
Answer:
Figures are objects that have the same shape, but may have different sizes.
Similar figures are figures that have the same shape but different sizes, with corresponding angles equal and side lengths proportional. This mathematical concept can be applied to many real-world and artistic comparisons.
The definition of similar figures in mathematics is that they are figures that have the same shape but may differ in size. This means that corresponding angles of similar figures are equal, and the lengths of corresponding sides are proportional. For example, all circles are similar to each other since they all have the same shape, regardless of their diameter. A real-world example can be seen when comparing photographs of objects that are the same shape but different sizes, such as a large elephant and a small toy elephant. Despite the size difference, if both are scaled versions of each other, they are considered similar figures.
The concept of similarity extends to various fields and contexts. In art analysis, similar figures may refer to recurring shapes or themes within artworks. An understanding of figure-ground perception, as seen in optical illusions like a vase or two faces, also plays on the concept of recognizing similar shapes within different contexts.
