Explanation:
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]

Remember to include a:
topic sentence that connects to the audience.
claim, reason, and evidence.
counterclaim and rebuttal.
call to action.
Write your speech in the space below:
Answer:
I think the bake sale would be better because, if one we're to do a car wash they may not know how to wash a car and selling baked goods is WAY easier than a car wash. A car wash can be bad depending on the weather and the bake sale. So I would chose the bake sale, it's easier, faster and much more.
Explanation:
want a short speech?
Answer:
Friends: What should we do to raise money? A bake sale will help us raise money for the local food bank because bake sales can attract people from outside the school community. The neighboring town was able to raise over $5,000 at their bake sale. Although the car wash is a good idea, people are more interested in buying homemade food. I strongly urge you to vote for the bake sale.

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.

Write a short essay citing the significance of cell signals and their effects on functions in the cytoplasm and functions within the nucleus?
Answer:
a short essay citing the significance of cell signals and their effects on functions in the cytoplasm and functions within the nucleus?
The mechanism of cell signaling promotes the relocalization of effector molecules from the region of the cytoplasm to the nucleus.
What is the significance of cell signaling?The significance of cell signaling is determined by the fact that it is the basic methodology through which specific information and messages are transferred from the surface of the cell to the cytoplasm and ultimately to the nucleus. This leads to alterations in gene expression.
The mechanism of cell signaling initiates when a ligand is bind to its receptor present on the membrane of the cell. A downstream signaling cascade runs after the successful binding of the ligand to its receptor. This binding is more specific.
It firstly affected the cytoplasm and allows it to change its functions according to the need of the cell during the process, which ultimately leads to the alteration in the morphology and functionality of the nucleus which is primarily responsible for transferring genetic information from one generation to the next.
