Find the measure of X, Y and Z in simplest form:
Answer/Explanation:
[tex] 12^2 = 16*x [/tex] (altitude to hypotenuse theorem)
Solve for x using this equation
[tex] 144 = 16x [/tex]
[tex] \frac{144}{16} = x [/tex] (division property of equality)
[tex] 9 = x [/tex]
[tex] x = 9 [/tex]
[tex] y^2 = 12^2 + x^2 [/tex] (pythagorean theorem)
[tex] y^2 = 12^2 + 9^2 [/tex] (substitution)
[tex] y^2 = 144 + 81 [/tex]
[tex] y^2 = 225 [/tex]
[tex] \sqrt{y^2} = \sqrt{225} [/tex]
[tex] y = 15 [/tex]
[tex] z^2 = (x + 16)^2 - y^2 [/tex] (pythagorean theorem)
[tex] z^2 = (9 + 16)^2 + 15^2 [/tex] (substitution)
[tex] z^2 = 25^2 + 15^2 [/tex]
[tex] z^2 = 625 + 225 [/tex]
[tex] z^2 = 850 [/tex]
[tex] \sqrt{z^2} = \sqrt{850} [/tex]
[tex] z = \sqrt{25*34} [/tex]
[tex] z = 5\sqrt{34} [/tex]

To attend a particular camp, a student must be either at least 13 years old or in grade 9 or higher, but must not yet be 18 years old. Let age represent a student’s age and let grade represent the student’s grade level. Which of the following expressions evaluates to true if the student is eligible to attend the camp and evaluates to false otherwise?
((age ≥ 13) OR (grade ≥ 9)) AND (age ≤ 180
((age ≥ 13) OR (grade ≥ 9)) AND (age < 18)
((age ≥ 13) OR (grade ≥ 9)) OR (age ≤ 18)
((age ≥ 13) OR (grade ≥ 9)) OR (age < 18)
Answer: b
Explanation:
The correct boolean expression which correctly represents the conditions and evaluates to true ls the option B.
Using the following boolean evaluation rule :
T or T = T T or F = TT and F = F((age ≥ 13) OR (grade ≥ 9)) AND (age ≤ 18)
(T or T) and F ( less than 18)
T and F = False
((age ≥ 13) OR (grade ≥ 9)) AND (age < 18)
(T or T) and T
T and T = True
The third option is wrong as the age must be less than 18Fourth option is wrong as the second operator should be ANDTherefore, the correct option is B.

Expain why acid forming in the ocean would affect the ecosystem.
Answer:
The amount of carbonate, a main building block in sea water, is reduced by ocean acidification. This makes it harder for marine organisms to shape their shells and skeletons, such as coral and some plankton, and existing shells will begin to dissolve.
Answer:
The ecosystem would start to become empty
Explanation:
Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve. The impacts of ocean acidification are not uniform across all species. Hopefully the explanation and answer helps!
“Gettysburg Address”
by Abraham Lincoln
Which of the following basic sentence types appear in the passage?
I. interrogative
II. imperative
III. declarative
A.
II only
B.
III only
C.
I and III
D.
II and III
E.
I, II, and III
Answer:
D. II and III
Explanation:
Interrogative phrases are those that present a type of questioning, a type of question. In “Gettysburg Address,” Lincoln makes no question and for that reason, we can say that there are no interrogative phrases in the speech.
Almost every discourse contains declarative sentences that are phrases where the author finds a fact. Lincoln uses this type of phrase right at the beginning of the discreet, when he states that "87 years ago, our parents gave birth, on this continent, to a new Nation, conceived in Liberty and devoted to the principle that all men are born equal."
Lincoln also uses imperative phrases that are phrases used to express a request, an order or an instruction. It is possible to see these phrases at the very end of the speech when Lincoln says "It is up to us, the living, to dedicate ourselves today to the work unfinished up to this point so remarkably advanced by those who fought here."
N2O5 reacts with water to produce nitric acid. If 1.93 moles of N2O5 react with excess water, how many moles of nitric acid can be produced?
The balanced chemical equation showing the reaction between dinitrogen pentoxide (N₂O₅) with water H₂O can be computed as follows:
[tex]\mathbf{N_2O_5 + H_2O \to 2HNO_3}[/tex]
From the given information, the amount of water H₂O is present in excess, as such dinitrogen pentoxide (N₂O₅) is regarded to be the limiting reagent.
However,
if 1 mole of dinitrogen pentoxide (N₂O₅) result in 2 moles of HNO₃∴
1.93 moles of N₂O₅ will result in = (2 × 1.93) moles of HNO₃
= 3.86 moles of HNO₃
Therefore, we can conclude that the reaction between 1.93 moles of N₂O₅ with water will produce 3.86 moles of nitric acid HNO₃.

What are some consequences of globalization?
Well, global economic growth and industrial productivity are both the driving force and the major consequences of globalization. They also have big environmental consequences as they contribute to the depletion of natural resources, deforestation and the destruction of ecosystems and loss of biodiversity.
Answer:
Globalization sure does come with a lot of consequences. Some of them are:
(1) Globalization restricts the growth of local industries (especially in the case of textiles & automobiles) as the imported goods are cheaper than the local goods.
(2) It causes poor work conditions for the workers as they have to work for longer periods of time with less wages.
(3) Globalization also affects the economy & the countries that export goods earn more or have MNCs in other places than countries that import goods.

What is the distance between the points (-7,3) and (4,-5) on the
coordinate plane?
O A. V13
O B. √57
O C. 7125
O D. 1185
The distance between these given points on a coordinate plane is equal to: B. √57
Given the following points:
Points on the x-axis = (-7, 4).Points on the y-axis = (3, -5).How to calculate the distance on coordinates?Mathematically, the distance between points that are on a coordinate plane is calculated by using this formula:
Distance = √[(x₂ - x₁)² - (y₂ - y₁)²]
Substituting the given points into the formula, we have;
Distance = √[(4 - (-7))² - (3 - (-5))²]
Distance = √[(4 + 7)² - (3 + 5)²]
Distance = √[11² - 8²]
Distance = √[121 - 64]
Distance = √57
