Answer:
800
Step-by-step explanation:
I rounded 39 to 40 and 24 to 20 to get numbers that are eadult multiplied
then we can do 40*20 which is 800 using mental math
hope this helps <3
Answer:
1000
Step-by-step explanation:
4*2 = 8
40 * 20 = 800
4*5 = 20
40* 5 = 200
40 * 20 + 40 * 5 = 800 + 200 = 1000
40 * 25 = 1000
find the value of x please help me
Answer:
x = 25
Step-by-step explanation:
Sun of the exterior angles of a quadrilateral = 360°
Therefore:
x + 40 + 6x + 2x + 20 + 3x = 360
Add like terms
x + 6x + 2x + 3x + 40 + 20 = 360
12x + 60 = 360
12x = 360 - 60
12x = 300
x = 300/12
x = 25

Answer:
8 of the 28 horses would be palomino horses
Step-by-step explanation:
First off, we understand that there are 10 palomino horses and 25 others, meaning there are 35 total.
The question wants to know that if 28 horses came out, how many of them would be palomino horses.
We know that the palomino horses are [tex]\frac{10}{35}[/tex]
What we need to know is [tex]\frac{x}{28}[/tex]
to find x, we cross multiply
[tex]\frac{10}{35} = \frac{x}{28}[/tex]
10 x 28 and 35 x X
280 = 35x
Divide both sides by 35
x = 8
8 of the 28 horses would be palomino horses

Which choices are correct when determining the distance between −56 and 44?
A) The distance is 12 units.
B) The distance is 100 units.
C) distance = |−56 + 44|
D) distance = |−56 − 44|
E) distance = −|−56 + 44|
The correct way of determining the distance between −56 and 44 is distance = |−56 − 44|
What is distance?Distance is referring to the numerical measurement of how far an object is from a particular place.
Given that, what is correct way to determine the distance between -56 and 44,

Can you show me how to set up the proportion?
Answer:
Step-by-step explanation:
First of all, write the similarity statement for the triangles.
ΔCDE ~ ΔCBA
Identify the line segments in each triangle that you know. Preferably, choose ones that correspond.
CE = 27, DE = the length we want to find . . . . known segments in ΔCDE
CA = (18+27) = 45 . . . . . corresponds to CE
BA = 28 . . . . . . . . . . . . . corresponds to DE
__
The ratios of corresponding line segments are equal:
DE/CE = BA/CA . . . . this is the proportion you want to set up*
DE/27 = 28/45
Multiply by the denominator of DE/27 to eliminate that:
DE = 27(28/45)
DE = 16.8
_____
* I usually choose to put the unknown variable in the numerator of a proportion, so that solving it only involves multiplication by the denominator. If you put the variable in the denominator, the solution takes an extra step.
a= (5/2) b= (-1/7)

Opening Exercise
The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?
Discussion
When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).
Exploratory Challenge
Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.
Does every figure have a line of symmetry?
If a student were going to write about their favorite food, they would want to include sensory language that focuses on. help please
Answer:
Here are the answers
Step-by-step explanation:
1. taste and smell
2. they allow the reader to feel as if he or she is in the story
3. touch
4. to make the writing more interesting and vivid, to provide greater detail to a narrative
Language Arts 6 B Unit 7 Lesson 13
Students would want to include sensory language which describes in the solution part that focuses on writing about their favorite food.
What is sensory language?Sensory Language is a word or words used to evoke mental imagery and help the reader visualize the tale or poetry. Imagery is a literary method that appeals to the reader's senses, whereas Sensory Language is a writing style and how writers utilize words to generate images for the readers.
When writing about their favorite food, a student might want to include sensory language that focuses on how the food looks, smells, tastes, feels, and sounds. This can help to paint a vivid picture for the reader and make the experience of reading about the food more immersive.
For example, if the student's favorite food is pizza, they might describe the golden, crispy crust; the savory, spicy tomato sauce; the gooey, melted cheese; the spicy sausage and bell peppers; and the satisfying crunch that it makes when they take a bite. They might also describe the way the warm, comforting aroma of the pizza fills the room as it cooks, or the way the different textures and flavors come together in each bite to create a satisfying and delicious meal. By using descriptive language that focuses on the senses, the student can help the reader to better understand and share in their love of the food.

Determine if the following system of equations has no solutions, infinitely many
solutions or exactly one solution.
-5x + y = -2
20x-4y = 8
Answer:
Infinite solutions.
Step-by-step explanation:
The given equations are :
-5x + y = -2 .....(1)
20x-4y = 8 .....(2)
We have,
a₁ = -5, a₂ = 20, b₁ = 1, b₂ = -4, c₁ = -2 and c₂ = 8
[tex]\dfrac{a_1}{a_2}=\dfrac{-5}{20}=\dfrac{-1}{4}\\\\\dfrac{b_1}{b_2}=\dfrac{1}{-4}=\dfrac{-1}{4}\\\\\dfrac{c_1}{c_2}=\dfrac{-2}{8}=\dfrac{-1}{4}[/tex]
It means,
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]
So, the system of equations has infinite solutions.
Quadrilateral A'B'C'D' is the result of dilating quadrilateral ABCD about point D by a scale factor of 3/2. Determine whether each claim about the properties of ABCD and A'B'C'D' is true or false.
The perimeters of ABCD and A'B'C'D' are the same (True or False)
The lengths of segment CD and segment C'D' are equal. (True or False)
Answer:
Both are false
Step-by-step explanation:
The shape underwent dilation, meaning that it is no longer the same size. All the proportions and ratios of the sides stayed the same, but their lengths all changed. Therefore, the perimeters of the two shapes are cannot be the same and the lengths of segments CD and C'D' must be different.
