a veternarian treated 7 dogs 13 cats 4 horses and three ferrert what was the percentage of his paitents were small animals
Answers
Answer:
As per your defention, horses are the only thing considered "not small". To find the percentage, you take the number of what you are trying to find the percentage of divided by the total number.
So, 7 dogs + 13 cats + 3 ferrets = 23 Small animals
7 dogs + 13 cats + 3 ferrets + 4 horses = 27 total animals.
So,
23/27 * 100
The reason we multiply by 100 is because the division gives us a decimal, and a percentage is a part out of 100.
So by doing the calculation we get
85.18%

Find sin(theta) , if cos(theta)=(4/9) and tan(theta) < 0
Answers
Recall that
cos²(x) + sin²(x) = 1
for all x, so that
sin(x) = ± √(1 - cos²(x))
Given that cos(θ) = 4/9 > 0, and
tan(θ) = sin(θ) / cos(θ) < 0
it follows that sin(θ) < 0, so
sin(θ) = - √(1 - cos²(θ)) = - √(1 - (4/9)²) = - √(65)/9
The value of sinθ is √(65)/9.
What is a sine function?The sine function in trigonometry is the ratio of the hypotenuse's length to the opposite side's length in a right-angled triangle. To determine a right triangle's unknown angle or sides, utilize the sine function.
Since cos(theta) = 4/9 and tan(theta) < 0, we know that theta is in the second quadrant of the unit circle, where cosine is positive and sine is positive.
We can use the Pythagorean identity to find sin(theta):
sin²(theta) + cos²(theta) = 1
Substituting in the given value of cos(theta), we get:
sin²(theta) + (4/9)² = 1
sin²(theta) + 16/81 = 1
sin²(theta) = 1 - 16/81
sin²(theta) = 65/81
Taking the square root of both sides, we get:
sin(theta) = ± sqrt(65)/9
Since theta is in the second quadrant where sine is positive, we can take the positive root:
sin(theta) = sqrt(65)/9
Therefore, sin(theta) = sqrt(65)/9.

Graph B (bottom left)
Step-by-step explanation:
Let's eliminate answers by reading the prompt:
Jaelene drains some of the water from a pool at a constant rate.
These are two big clues. Since Jaelene drains water, she is losing water, and at a constant rate. Therefore, we can eliminate A and C because you would be gaining water in the pool and not draining.
She stops draining water to fix the hose and then fills the pool up with water again.
Also important clues. If you stop draining water, the water level does not change. Also, since the pool is filling up, that means we are gaining water. Therefore, we can eliminate option D because that would mean we're still draining water but we're not in this case.
Therefore, the only correct answer is graph B (bottom left)

What is a boxplot?A boxplot is defined as a common method for visualizing data distribution based on a five-number summary. (minimum, first quartile (Q1), median, third quartile (Q3), and maximum).
Given that,
The box-and-whisker plot shows the number of books read by history students during the last school year.
The box extends from 4 to 15 on the number line.
There is a vertical line at 8, median = 8.
The whiskers end at 4 and 15,
So, minimum of data = 4 and maximum of data = 15.
∵ Range = maximum of data - minimum of data
Range = 15 - 4
Range = 11
Hence, the range of the data is 14.

Please check the attached graph.
The point of intersection will be: (x, y) = (15, -2)The solution will be:
(x, y) = (15, -2)Hence, option (B) is correct.
Step-by-step explanation:
Please note that the point of intersection is the solution of the two lines on a coordinate plane.Given the system of equation
[tex]\begin{bmatrix}y=\frac{2}{3}x-12\\ y=2x-32\end{bmatrix}[/tex]
Please check the attached graph,
The red line is representing the equation [tex]y\:=\:\frac{2}{3}x-12[/tex]The blue line is representing the equation [tex]y\ =\ 2x-32[/tex]From the attached graph, it is clear that both the lines meet at the point (15, -2).
In other words,
at x = 15, y = -2
Thus, the point of intersection will be: (x, y) = (15, -2)
We already know that the point of intersection is the solution of the two lines on a coordinate plane.
Therefore, the solution will be:
(x, y) = (15, -2)
Hence, option (B) is correct.
4. If 100.0g of nitrogen gas (N2) is reacted with 100.0g of hydrogen gas (H2) to form NH3. What are the limiting and excess reactants?
Hint: Convert grams to moles for each reactant and then convert to moles of NH3.

Answers
Nitrogen (N) has a molar mass of about 14.007 g/mol, so you have
100.0 g N₂ = (100.0 g) • (1/28.014 mol/g) ≈ 3.570 mol N₂
Hydrogen (H) has a molar mass of about 1.008 g/mol, so
100.0 g H₂ = (100.0 g) • (1/2.016 mol/g) ≈ 49.60 mol H₂
In the balanced reaction, 1 mole of N₂ reacts with 3 moles of H₂ to make 2 moles of NH₃. We have
3.570 • 3 ≈ 10.71
so the reaction would use up all 3.570 mol N₂ and 10.71 mol H₂ to produce about 7.139 mol NH₃.
(A) H₂ is the excess reactant. There is an excess of 49.60 - 10.71 ≈ 38.89 mol H₂.
(B) N₂ is the limiting reactant. All of the N₂ gets consumed in the reaction.
(C) NH₃ has a molar mass of (14.007 + 3 • 1.008) g/mol = 17.031 g/mol. This reaction would theoretically yield about 7.139 mol NH₃, or
7.139 mol NH₃ = (7.139 mol) • (17.031 g/mol) ≈ 121.6 g NH₃

Lydia receives a $2,000 gift and wants to open a savings account. Which bank interest would be the best for her if the current inflation rate is 3.5%?
Answers
Answer:
the best interest rate would be a minimum of 3.5% annual interest
Step-by-step explanation:
An inflation rate of 3.5% would mean that the buying power of Lydia's money would decrease by 3.5% every single year. Therefore, the best interest rate would be a minimum of 3.5% annual interest. That way she would at least maintain the same buying power with her money as the day that she first placed it in the account. Any interest rate higher than 3.5% would be even better as Lydia will begin to make a profit from her savings.
