Answer:

  x = 19

Step-by-step explanation:

When a triangle is cut by a line parallel to its base, the resulting two triangles are similar. That means corresponding sides are proportional (their ratios are equal).

There are several ways the ratios can be written, but I like to choose one that has the variable in the numerator. Here's the proportion and its solution.

  \(\dfrac{x+5}{16}=\dfrac{30}{20}\\\\x+5=24\qquad\text{multiply both sides by 16}\\\\x=19\qquad\text{subtract 5 from both sides}\)

_____

Additional comment

Technically, the corresponding sides of the triangles would be ...

Since the parts labeled (x+5) and 16 are each the same fraction of their entire side, those parts are corresponding also, and will have the same proportion as other corresponding sides.

Step-by-step explanation:

Answer:

From the question we are told that

  The  equation is  \(2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0\)

Generally the goal of this solution is to prove that the implicit solution of the differential  equation above is  \(ln(x^2 + 11) + csc(y) = C.\)

First Step  

    Differentiate the solution with respect to  x  

   \(0  = \frac{2x}{ x^2 + 11}  + [-cot * csc(y) ]\frac{dy}{dx}\)

=> \(0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin(y) }* \frac{1}{sin(y)} ]\frac{dy}{dx}\)  

=>  \(0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin^2(y) }]\frac{dy}{dx}\)

=>  

multiply through by  \(sin^2(y)\) , \( x^2 + 11\), \(dx\)

So

=> \(2 x (sin^2(y) dx + [-cos(y) (x^2 + 11)]dy = 0\)

Looking at the equation obtained we see that it is equivalent to the differential  equation hence  the implicit solution of \(2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0\) is   \(ln(x^2 + 11) + csc(y) = C.\)

Answer:

The t-score that should be used to find the 90% confidence interval is 1.729.

Step-by-step explanation:

The (1 - α)% confidence interval population mean, when the population standard deviation is not known is:

\(CI=\bar x\pm t_{\alpha/2, (n-1)}\cdot \frac{s}{\sqrt{n}}\)

The information provided is:

n = 20

α = 0.10

The degrees of freedom of t-statistic will be:

df = n - 1

   = 20 - 1

   = 19

Compute the critical value of t as follows:

\(t_{\alpha/2, (n-1)}=t_{0.10/2, 19}=1.729\)

*Use a t-table.

Thus, the t-score that should be used to find the 90% confidence interval is 1.729.

The best-fit equation is 10x+7y _> 200

Fitting an equation to data is finding a linear, quadratic, exponential, or any other sort of function whose graph includes, or comes as close as possible to, a given set of data in the form of ordered pairs. The relative predictive power of a model shows how accurately the model is related to the data.

The theoretical pattern best accounts for the relationships among variables in a data set. For example, a regression equation having the best fit to sample data is the one that minimizes differences between observed and predicted values.

Answer:

12 people are need to walk 24 dogs

Step-by-step explanation:

12/2=6

24/2=12

Answer:

12 people can walk 24 dogs.

Step-by-step explanation:

Given information,

→ 6 people can walk 12 dogs.

→ People required for 24 dogs = ?

Let us assume that,

→ Missing value = p

Forming the equation,

→ 6/12 = p/24

Then the value of p will be,

→ 6/12 = p/24

→ p/24 = 6/12

→ p × 12 = 6 × 24

→ 12p = 144

→ p = 144/12

→ [ p = 12 ]

Hence, the value of p is 12.

Answer:

\(x=30\\y=68\\z=82\)

Step-by-step explanation:

x = measure of the first angle

y = measure of the second angle

z = measure of the third angle

The sum of the measures of the second and third (y+z) is five times the measure of the first angle (=5x)

\(y+z=5x\)

The third angle is 14 more than the second

\(z=y+14\)

And remember that the sum of these three angles must be equal to 180.

\(x+y+z=180\)

Let's take these equations

\(y+z=5x\\z=y+14\\x+y+z=180\)

If you take a look at the first equation, we have y+z = 5x and we have y+z in the third equation as well, we can replace that....

\(x+y+z=180\\x+(y+z)=180\\x+(5x)=180\)

Distribute the + sign

\(x+5x=180\)

Combine like terms;

\(6x=180\)

Divide by 6.

\(x=\frac{180}{6}\\ x=30\)

We have now defined that the measure of the first angle is 30º.

Let's take another equation... for example \(z=y+14\)

I'm going to take this one because if I replace x and z in the third equation, all I'll have left will be y.

\(x+y+z=180\\30+y+(y+14)=180\)

Distribute the + sign and Combine like terms;

\(30+y+y+14=180\\44+2y=180\\\)

Subtract 44 to isolate 2y.

\(2y=180-44\\2y=136\)

Now divide by 2.

\(y=\frac{136}{2}\\ y=68\)

We already have the value of x and y. Once again, replacing this in the third equation will leave us with z to solve for.

\(x+y+z=180\\30+68+z=180\\98+z=180\\z=180-98\\z=82\)

Answer:

4

Step-by-step explanation:

I like to use the FOIL method! I've attached a quick picture of how it works below, but basically you multiply the first terms. Next, multiply the outside/outer terms. Then, multiply the inside/inner terms. Lastly, you multiply the last terms.

In this question, the binomial is (x + 2)².

You can expand this to be (x + 2)(x + 2).

When you expand it using the FOIL method, you get x times x, which is x².

Next, the outside/outer terms are x and 2, which is 2x.

Then, you multiply the inside/inner terms 2 and x, which is 2x.

Last, you multiply the last terms, which are 2 and 2, which is 4.

When you put them together, it looks like this:

x² + 2x + 2x + 4.

You can simplify this to x² + 4x + 4.

So your answer is 4.

In a case whereby Darren says that more students hands are 4 2/4 inches longer than 4 and 5 1/4 inches combined, he is wrong

\(4\frac{2}{4}\) that was given in the question can be seen as mixed fraction, we can expressed this as improper fraction so that it will be easier to handle.

\(4\frac{2}{4} = \frac{16+4}{2}\)

=\(\frac{18}{4}\)

Then \(4 + 5\frac{1}{4} = \frac{16}{4} +\frac{20+1}{4} \\\\=\frac{37}{4}\)

Then after expressing the given fractions as improper fraction we can now compare them so that e will know may be Darren is right or wrong, then here we can see that \(\frac{18}{4}\) is less than \(\frac{37}{4}\) Hence, Darren is wrong.

Answer:

D. A pair of intersecting lines

Step-by-step explanation:

A conic section is a fancy name for a curve that you get when you slice a double cone with a plane. Imagine you have two ice cream cones stuck together at the tips, and you cut them with a knife. Depending on how you cut them, you can get different shapes. These shapes are called conic sections, and they include circles, ellipses, parabolas and hyperbolas. If you cut them right at the tip, you get a point. If you cut them slightly above the tip, you get a line. If you cut them at an angle, you get two lines that cross each other. That's what happened in your question. The plane cut the cone at an angle, so the curve is two intersecting lines. That means the correct answer is D. A pair of intersecting lines.

Answer: 803.84cm3

Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.

To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.

4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.

Now, we have the area of the circle. 50.24cm squared!

The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,

16cm x 50.24cm squared = 803.84cm cubed.

The volume of the can of soup is 803.84cm cubed.

Answer: c

Step-by-step explanation:

If John solved the equation x² - 10x + 8 = 0 by completing the square, one of the steps in his process would be: A. (x - 5)² = 17.

In Mathematics, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

x² - 10x + 8 = 0

x² - 10x = -8

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² - 10x + (-10/2)² = 8 + (-10/2)²

x² - 10x + 25 = -8 + 25

x² - 10x + 25 = 17

By simplifying, we have;

(x - 5)² = 17
