A restaurant's seating is completely full. There
are some four-person tables and 8 tables withcouples. If there are 56 people here, how many
four-person tables are there?

Answers

If there are 8 tables with couples, that would cover 16 out of 56 people, which means that 40 people total are sitting at four-person tables. Since we now know that 40 people are sitting at four-person tables, and we can obviously tell that four people sit at a four-person table, we can divid 40 by 4 to find that there are 10 four-person tables.

Final answer: 10 four-person tables.

A flavored drink is made using a mixture of a powder drink mix and water, with ratio of powder to water that is 3:2 based on weight. If 20 g of the powdered mix is needed for a certain amount of the flavored drink, how much water will be needed?

Answers

Answer:

[tex]13.\overline 3[/tex]

Step-by-step explanation:

We can use proportions to find the amount of water needed

Let [tex]x[/tex] be the amount of water needed

[tex]\frac{3}{2} = \frac{20}{x}[/tex] (with the ratio being 3 powder to 2 water)

Now we can cross multiply and solve for [tex]x[/tex]

[tex]3(x) = 20(2)\\3x = 40\\x = \frac{40}{3}\\ x = \boxed{13.\overline3}[/tex]

You will need [tex]13.\overline3[/tex] grams of water to make the flavored drink.

The probabilities are:

P(red) = 5/24P(orange) =  0 P(blue) =  1/3P(not green)= 17/24P(green or black) = 11/24P(not yellow)  = 1.

How to find the probabilities?

The probability of getting a particular color of marble, is given by the quotient between the number of marbles of that color and the total number of marbles.

Here we have:

5 red marbles.7 green marbles.4 black marbles.8 blue marbles.

So the total number is 5 + 7 + 4 + 8 = 24.

Then:

P(red) = 5/24P(orange) = 0/24 = 0  (because there are 0 orange marbles).P(blue) = 8/24 = 1/3P(not green) = (24 - 7)/24 = 17/24P(green or black) = (4 + 7)/24 = 11/24P(not yellow) = 24/24 = 1 (because there aren't yellow marbles).

Answers

Component form of u is (-18,13) and The magnitude of u is 22.2

What is a vector?

A vector is a two-dimensional entity with both magnitude and direction. A vector can be visualized geometrically as a directed line segment.

The component form of a vector is an ordered pair that describes the change in x and y values

This is mathematically expressed as (Δx, Δy) where Δx=x₂-x₁ and Δy=y₂-y₁

Given ;

Initial points of the vector as (14,-6)

The terminal point of the vector is (-4,7)

Here x₁=14,x₂=-4, y₁=-6,y₂=7

The component form of the vector u is (-4-14,7--6) =(-18,13)

Finding the Magnitude of the vector

u=√(x₂-x₁)²+(y₂-y₁)²

u=√-18²+13²

u=√324+169

u=√493

u=22.2

What is Vertical Angles Theorem?

Theorem of vertical angles or angles that are vertically opposing According to the theorem, two opposing vertical angles that are created when two lines cross one other are always equal to one another.

As AE = EC and BE = ED (by the definition of bisection) suggest that triangles AEB and CED are congruent (by the SAS criterion for congruence),

It is claimed in step 3 of the provided proof that mAEB = mCED. The corresponding angles of two triangles are equal when they are congruent. Since mAEB = mCED, it follows that the measure of angle AEB must be equal to the measure of angle CED.

This step is crucial because it proves the equality of the respective angles in the congruent triangles AEB and CED. This equality is then utilized in step 4 to prove that the two triangles satisfy the SAS criterion, which is a congruence criterion.

Steps 5 through 11 then employ the congruence of triangles AEB and CED to demonstrate that the quadrilateral ABCD is a parallelogram.

Thus, option D is correct.

[tex]4\sqrt{3}[/tex]

Step-by-step explanation:

Since <PDA is right, the vertical angle, <BDC is right as well. Using sum of angles in a triangle, the angles in triangle BDC sum to 180, and for solving for <DCB, you get 30 degrees.

The line connecting the intersection of the tangents to the radius bisects the angle formed by the tangents; therefore, m<PCA is also 30 degrees.

A radius drawn to the point of tangency is perpendicular to the tangent, so <PAC is a right triangle. We can use sum of angles in a triangle for triangle PAC. Since <PCA is 30 and <PAC is right, <DPA is 60 degrees.

Now, we can look at triangle DPA, using sum of angles in a triangle, we can conclude triangle DPA is a 30-60-90 special right triangle. The leg opposite the 60 degree angle is √3 times the leg opposite the thirty degree angle. Since <DPA is 60 degrees and <PAD is 30:

[tex]DP\sqrt{3} = 6\\DP = \frac{6}{\sqrt{3} } \\DP = \frac{6}{\sqrt{3} } \times \frac{\sqrt{3} }{\sqrt{3} } \\DP = \frac{6\sqrt{3} }{3} \\DP = 2\sqrt{3}[/tex]

Also, in a 30-60-90, the hypotenuse is twice the leg opposite the 30 degree angle, so x is 2 * 2√3. or [tex]4\sqrt{3}[/tex].
