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
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.

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.

Manatees are an endangered species of herbivorous, aquatic mammals found primarily in the rivers and estuaries of Florida. As part of its conservation efforts, the Florida Fish and Wildlife Commission records the cause of death for every recovered manatee carcass in its waters. Of the 392 recorded manatee deaths in 2012, 68 were perinatal and 81 were caused by collision with a watercraft.
Required:
a. What is the probability that the death of a randomly selected manatee was due to collision with a watercraft?
b. What is the probability that the death was not due to collision with a watercraft?
c. What is the probability that the cause of death was due to perinatal problems or collision with a watercraft?
Answer:
a) 0.206 , b) 0.794 , c) 0.38
Step-by-step explanation:
a) Prob(watercraft collision death)= Watercraft collision deaths / Total deaths = 81 / 392 = 0.206
b) Prob (Death non watercraft collison) = 1 - Prob (Death watercraft collision) = 1 - 0.206 = 0.794
c) Prob (Prenatal or watercraft collision death) = (68 + 81) / 392 = 0.38

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.

Find the discriminant and the num
x2 + 2x + 7 = 0
A. 28; two real roots
Answer:
Discriminant = -24, no real roots.
Step-by-step explanation:
The discriminant is what's inside the square root in the quadratic formula.
The quadratic formula is:
[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
a = 1
b = 2
c = 7
The question wants the discriminate, we can just focus on the square root part.
When we plug in the parts we got, it becomes:
[tex]\sqrt{4-4(1)(7)}\\\sqrt{4-28} \\\sqrt{-24}[/tex]
Since the inside of the square root is negative, there are no real roots.
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.

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.
