Find the value of X in each figure below

Mrrafil [7]

Answer:

168). C

169). C

170). C

Step-by-step explanation:

For the first angle, it is a right angle, so it measures 90 degrees.

x and 50 are complementary angles, meaning they add up to 90 degrees.

So, subtract 50 from 90 to get 40, which is equal to x.

45 and x are supplementary angles, meaning they add up to 180 degrees.

Subtract 45 from 180 to get 35 degrees, which is the measure of angle x.

All angles in a triangle add up to 180 degrees.

So, 70 + 56 = 126, 180 - 126 = 54.

Since the unknown angle is x - 5, 54 + 5 = 59, which the the measure of angle x - 5.

I NEED HELP FAST

deff fn [24]

The restaurant served 70 specials in all, 80% of which were salmon filets. It says to find salmon filets that the restaurant served last night.

So we just need to find 80% of 70.

Therefore, Number of Salmon Filets = 0.8*70 = 56.

Hence, the restaurant served 56 salmon filets.

I'LL MARK BRAINLIEST PLEASE HELP

Fudgin [204]

<h3>Answer:</h3>

The number is 72

<h3 /><h3>Step-by-step solution:</h3>

Its hard to explain this really. Its kind of like a trial-and-error. Multiplying numbers by 8 with the second digit being 5 more than the units digit.

It takes time but eventually, youll find the answer.

Plus, You can search it up since theres already a pre-existing answer to this same question.

The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.65 millimeters and a standard deviat

nexus9112 [7]

Answer:

Two diameters that separate the top 4% and the bottom 4% are 5.77 and 5.53 respectively.

Step-by-step explanation:

We are given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.65 millimeters and a standard deviation of 0.07 millimeters.

<em>Let X = diameters of bolts produced in a machine shop</em>

So, X ~ N( $\mu=5.65,\sigma^{2} = 0.07^{2}$ )

The z score probability distribution is given by;

Z = $\frac{X-\mu}{\sigma}$ ~ N(0,1)

where, $\mu$ = population mean

$\sigma$ = standard deviation

<u>Now, we have to find the two diameters that separate the top 4% and the bottom 4%.</u>

Firstly, Probability that the diameter separate the top 4% is given by;

P(X > x) = 0.04

P( $\frac{X-\mu}{\sigma}$ > $\frac{x-5.65}{0.07}$ ) = 0.04

P(Z > $\frac{x-5.65}{0.07}$ ) = 0.04

<em>So, the critical value of x in z table which separate the top 4% is given as 1.7507, which means;</em>

$\frac{x-5.65}{0.07}$ = 1.7507

$x-5.65 = 0.07 \times 1.7507$

$x$ = 5.65 + 0.122549 = 5.77

Secondly, Probability that the diameter separate the bottom 4% is given by;

P(X < x) = 0.04

P( $\frac{X-\mu}{\sigma}$ < $\frac{x-5.65}{0.07}$ ) = 0.04

P(Z < $\frac{x-5.65}{0.07}$ ) = 0.04

<em>So, the critical value of x in z table which separate the bottom 4% is given as -1.7507, which means;</em>

$\frac{x-5.65}{0.07}$ = -1.7507

$x-5.65 = 0.07 \times (-1.7507)$

$x$ = 5.65 - 0.122549 = 5.53

Therefore, the two diameters that separate the top 4% and the bottom 4% are 5.77 and 5.53 respectively.

What is the end behavior of the function?<img src="https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B4x%7D%7Bx-16%7D" id="TexFormula1

bazaltina [42]

From the asymptotes of the function, the end behavior is given by:

The vertical asymptote is x = 16.

The horizontal asymptote is y = 4.

<h3>What are the asymptotes of a function f(x)?</h3>

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.

The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

In this problem, the function is given by:

$f(x) = \frac{4x}{x - 16}$

For the vertical asymptote, it is when the denominator is of zero, hence:

x - 16 = 0 -> x = 16.

For the horizontal asymptote, we find the limit as x goes to infinity, hence:

$\lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{4x}{x - 16} = \lim_{x \rightarrow \infty} \frac{4x}{x} = \lim_{x \rightarrow \infty} 4 = 4$

Hence the end behavior is given by:

The vertical asymptote is x = 16.

The horizontal asymptote is y = 4.
