Okay, here we have this:
Considering the provided figure, we are going to find the missing sides, so we obtain the following:
Then according to the altitude rule we obtain the following equality:
(1/3)/x = x/(1/6)
Let's solve for x:
x^2=(1/3)(1/6)
x^2=1/18
x=√(1/18)
x=1/√18
x=1/(3√2)
x=√2/6
Now let's find the other two missing sides using the Pythagorean theorem:
\(\begin{gathered} z=\sqrt{\left(\frac{1}{3}\right)^2+\left(\frac{\sqrt{2}}{6}\right)^2}^ \\ z=\sqrt{\lparen1/9)+\left(2/36\right)} \\ z=\sqrt{\left(1/9\right)+\left(1/18\right)} \\ z=\sqrt{\left(2/18\right)+\left(1/18\right)} \\ z=\sqrt{3/18} \\ z=\sqrt{1/6} \\ z=1/\sqrt{6} \end{gathered}\)
Finally let's find y:
\(\begin{gathered} y=\sqrt{\left(1/6\right)^2+\left(\sqrt{2}/6\right)^2} \\ y=\sqrt{\left(1/36\right)+\left(2/36\right)} \\ y=\sqrt{3/36} \\ y=\sqrt{1/12} \\ y=1/\sqrt{12} \\ y=1/\left(2\sqrt{3}\right) \end{gathered}\)Related Questions

Find ƒ(1)
for the given
Answers
When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.
The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.
Replacing x with 1, we have:
ƒ(1) = -4(1) - 5
Simplifying further:
ƒ(1) = -4 - 5
ƒ(1) = -9
Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.
Let's break down the steps taken to arrive at the solution:
1. Start with the function f(x) = -4x - 5.
2. Replace x with 1 in the function.
3. Evaluate the expression by performing the necessary operations.
4. Simplify the expression to obtain the final result.
In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.
It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.
Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

List all the 4-tuples in the relation {(a,b,c,d) | a,b,c,d∈!+ , a+b+c+d = 6}
Answers
We have a total of seven 4-tuples that satisfy the given relation.The given relation is {(a,b,c,d) | a,b,c,d∈!+ , a+b+c+d = 6}. It can be understood as the set of 4-tuples (a, b, c, d) such that a, b, c, and d are positive integers and their sum is equal to 6.
Let's now list all the possible 4-tuples that satisfy the given relation. The possible combinations are as follows: (1, 1, 1, 3), (1, 1, 2, 2), (1, 2, 1, 2), (2, 1, 1, 2), (1, 2, 2, 1), (2, 1, 2, 1), and (2, 2, 1, 1).
Here's a brief explanation on how these 4-tuples were obtained. Let a, b, c, and d be positive integers such that a+b+c+d = 6. The least possible value that each variable can take is 1.
So, we start with a=1 and find all possible values of (b, c, d) that satisfy the given equation. Then, we move to a=2 and repeat the process. Finally, we list all the possible 4-tuples that we obtained.
Thus, we have a total of seven 4-tuples that satisfy the given relation.

Find the value of x assume the triangles are the same
Answers
1) In this problem, we need to find the constant of proportionality assuming these triangles are similar. So let's divide each corresponding leg:
\(\frac{22}{18}=\frac{33}{27}\Rightarrow\:k=\frac{11}{9}\)2) So, based on that constant of proportionality (k) we can find the missing leg.
\(\begin{gathered} x\div\frac{11}{9}=36 \\ \\ x\cdot\frac{9}{11}=36 \\ \\ 11\times\frac{9}{11}x=36\times11 \\ \\ 9x=396 \\ \\ \frac{9x}{9}=\frac{396}{9} \\ \\ x=44 \end{gathered}\)Note that since the triangle on the top is larger than the one on the bottom, we can tell that x must be larger than 36.

From the position of the metals on the electrochemical series, there would be no reaction of the solution with iron and copper.
What is the reactivity?We know that a reaction is said to have occurred between a metal and a solution if the metal is able to displace the cation that is in the solution. This displacement would in turn have a lot to do with the position of the metals in the electrochemical series.
Given that iron and copper are all less than aluminum which is the cation in the solution in the electrochemical series then it would not be possible for these metals to displace it in solution thus there would be no reaction.

FIND THE ERROR Josephina and Dario are estimating √50 .
Who is correct? Explain your reasoning.
Answers
The ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.
How to calculate the error?Suppose the actual value and the estimated values after the measurement are obtained. Then we have:
Error = Actual value - Estimated value
WE need to find the error Josephina and Dario are estimating √50
The actual value of \(\sqrt{ 50 } = 7.0710\)
So,
By Josephina
Error = Actual value - Estimated value
Error = 7.07 - 7
Error = 0.07
By Dario
Error = Actual value - Estimated value
Error = 7.07 - 25
Error = -17.92
Hence, the ERROR Josephina and Dario estimated √50 are such as 0.07 and -17.92.

What graph represents the piecewise-defined function ? y={6 if x <-3, 3 if -32
Answers
The graph of the piecewise-defined function will consist of two horizontal line segments.
The piecewise-defined function can be represented using a graph with two separate segments.
First, let's consider the segment where the value of y is 6 when x is less than -3. This means that for any x-value less than -3, the corresponding y-value is 6. This segment will be a horizontal line parallel to the x-axis, located at the y-coordinate of 6.
Next, let's consider the segment where the value of y is 3 when x is greater than or equal to -3 and less than or equal to 2. This means that for any x-value between -3 and 2 (inclusive), the corresponding y-value is 3. This segment will also be a horizontal line parallel to the x-axis, located at the y-coordinate of 3.
To summarize:
For x < -3, y = 6.
For -3 ≤ x ≤ 2, y = 3.
Therefore, Two horizontal line segments make up the graph of the piecewise-defined function. One segment will be located at y = 6, and the other segment will be located at y = 3. The vertical range of the graph will extend to include both y-values (6 and 3), while the horizontal range will depend on the given x-values and the interval specified.

-1/4 plus 3/5
Answer or else
Answers
The algebric expression -1/4 + 3/5 is equal to 7/20 when simplified.
To solve the expression -1/4 + 3/5, we need to find a common denominator for the fractions and then perform the addition.
The common denominator for 4 and 5 is 20. We can rewrite the fractions with this denominator:
-1/4 = -5/20
3/5 = 12/20
Now that the fractions have the same denominator, we can add them:
-5/20 + 12/20 = (-5 + 12)/20 = 7/20
Therefore, -1/4 + 3/5 is equal to 7/20.
To further simplify the fraction, we can check if there is a common factor between the numerator and denominator. In this case, 7 and 20 have no common factors other than 1, so the fraction is already in its simplest form.
Thus, the final answer is 7/20.

Sofia has a bag containing 8 blue beads and 7 red beads only.
She takes one bead out of the bag at random and replaces it.
She does this 90 times.
Find the number of times she expects to take a red bead.
Answers
Answer:
The answer is 42 times.
Step-by-step explanation:
The probability of taking out the red bead from the bag every time is
P = 7 ÷ (7 + 8) = 7/15
So, The number of times she expects to take a red bead is 'n'
Therefore,
n = 90 × 7/15
n = 6 × 7 = 42
Thus, The number of times she expects to take a red bead is 42.
during a single day at radio station WMZH,the probability that a particular song is played in 3/8.what is the probability that this thing will be played on exactly 2 days out of 3 days ?round to your nearest thousandth
Answers
The probability that the song will be played on exactly 2 days out of 5 days is approximately 0.164.
To find the probability that a particular song is played exactly 2 days out of 5 days at radio station WMZH, we can use the binomial probability formula.
The binomial probability formula is given by P(x) = C(n, x) * p^x * (1-p)^(n-x), where P(x) is the probability of x successful outcomes, n is the number of trials, p is the probability of a successful outcome on a single trial, and C(n, x) represents the binomial coefficient, which is the number of ways to choose x items from a set of n items.
In this case, we want to find the probability of the song being played exactly 2 days out of 5 days, so x = 2, n = 5, and p = 3/8.
Using the formula, we have:
P(2) = \(C(5, 2) * (3/8)^2 * (1 - 3/8)^(^5^-^2^)\)
C(5, 2) = 5! / (2! * (5-2)!) = 10
P(2) = 10 * (3/8)^2 * (5/8)^3
P(2) ≈ 0.164 (rounded to three decimal places)
