Answer:

27,600

Step-by-step explanation:

We use the following formula:-  

Number of permutations of r from n

= nPr

= n! / (n-r)!

I am assuming you don't allow repeated letters in the 4 letter codes.

Take S as the first letter. Then we have 3 letters extra out of 25 letters.

Using the above formula the possible ways of doing this is

25! / (25 - 3)!

25! / 22!

= 25*24*23

= 13800.

The same number is obtained if the first letter is a T.

So the answer is 2*13800

= 27,600

Answer:

10. It is a parallelogram.

11. The parallelogram is a rhombus.

Step-by-step explanation:

10. Use the given sets of congruent segments with congruent vertical angles XNY and WNZ to prove that triangles XNY and ZNW are congruent. Now use CPCTC to show that angles XYN and ZWN are congruent. They are alternate interior angles making sides XY and WZ parallel. Now use CPCTC to show that sides XY and WZ are congruent. Since a quadrilateral has two opposite sides that are both parallel and congruent, the quadrilateral is a parallelogram.

11. A rectangle and a square have 4 right angles. If you add 72 deg and 72 deg, you get 144 deg which is not a right angle. Since one angle of the parallelogram is not a right angle, the parallelogram is not a square or a rectangle.

There are two triangles. Let's look at the upper triangle. The triangle has 2 angles measuring 72 deg each. That means the opposite sides are congruent, and the triangle is isosceles. Since the quadrilateral is a parallelogram, opposite sides are congruent, so all 4 sides are congruent, and the parallelogram is a rhombus.

10. It is a parallelogram.

Answer:

[tex]\frac{13}{20}[/tex]

Step-by-step explanation:

First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:

[tex]\frac{3}{5} * 8 = \frac{24}{40}[/tex]

[tex]\frac{6}{8} * 5 = \frac{30}{40}[/tex]

[tex]\frac{24}{40} + \frac{30}{40} = \frac{54}{40}[/tex]

We can also show 2 brownies as [tex]\frac{2}{1}[/tex] or [tex]\frac{80}{40}[/tex]

Now we can subtract the two:

[tex]\frac{80}{40} -  \frac{54}{40} = \frac{26}{40}[/tex]

Simplify the fraction down by dividing by two:

[tex]\frac{13}{20}[/tex]

Which is the fraction of brownie left!

Olivia drinks 0.375 gallons of water.

Problem-solving is defining a problem; figuring out the purpose of the trouble; identifying, prioritizing, and selecting alternatives for an answer; and imposing an answer.

Problem-solving starts with identifying the issue. For example, a trainer may need to figure out a way to improve a scholar's overall performance on a writing talent test. To do that, the instructor will overview the writing exams looking for regions for improvement.

Calculation:-

Quantity of water Olivia took = half a gallon i.e 0.5 gallons.

Quantity of water Olivia drank =0.75 of 0.5

      ∴  75% of 0.5 gallons

          = 75/100 × 0.5

           = 0.375 gallons.

Thank you.

The solution to the first equation 4x – 5 = 16 is x = 5.25. The solution to the second equation 35 + 3x – 11 = 23 is x = -0.33. Both solutions have been rounded to two decimal places.

Let's solve these two equations one by one:

a. 4x – 5 = 16

b. 35 + 3x – 11 = 23

These are the solutions to the equations, rounded to two decimal places.

You can use any pair of angles together with the sides PQ and TS. If you use the vertical angles and one of ∠T or ∠S, then you must invoke the AAS postulate for congruence, as the side is not between the two angles.

Final answer:

By defining variables for the prices and setting up a system of equations, we determine that each shirt costs $12 and each pair of jeans costs $40 after solving the system using the elimination method.

Explanation:

The subject of this question is a problem involving systems of equations, which falls under the category of Mathematics. We are given a scenario where Lucy and Ethel are buying clothing at the same prices, but in different quantities and we need to determine the cost of each item. First, let's define variables: let s be the price of a shirt and j be the price of a pair of jeans. We then have two equations based on the purchases:

To solve these equations using the elimination method, we will multiply the first equation by 5 and the second by 4 to eliminate the jeans variable:

Subtract the second equation from the first:

Now divide by 2 to find the price of one shirt:

We can substitute s = $12 into the first original equation to find the price of a pair of jeans:

Answer:

[tex]f(x)=8x^2+73x-70[/tex]

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

[tex]f(x)=a(x-(-10))(x-\frac{7}{8})[/tex]

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

[tex]f(x)=8(x-(-10))(x-\frac{7}{8})[/tex]

now, we can simplify it

[tex]f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)[/tex]

so, we get

[tex]f(x)=8x^2+73x-70[/tex]

Answer:

B

Step-by-step explanation:

Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.

We have that the Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]  

Option D is correct

From the Question we are given

[tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex]

it is important to note that the rotation of the identity matrix  [tex]\begin{pmatrix}1 & 0\\0 & 1\end{pmatrix}[/tex] rotating across the Cartesian co-ordinate is a [tex]180 \textdegree[/tex] is going to give a matrix   [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]  

Therefore

The Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]  

Option D is correct

Answer:

a(n) = 0.55 + (n -5)0.07

Step-by-step explanation:

The cost goes up $0.07 for each additional minute, so that is the slope of the linear function. In point-slope form the equation can be written ...

... a(n) - 0.55 = 0.07(n -5)

adding 0.55, and rearranging slightly, this becomes ...

... a(n) = 0.55 +(n -5)0.07

Answer:

√85

Step-by-step explanation:

The distance formula tells you the distance between (x1, y1) and (x2, y2) is ...

... d = √((x2-x1)^2 +(y2-y1)^2)

For your points (-1, -4) and (-8, 2), the distance is ...

... d = √((-8 -(-1))^2 +(2 -(-4))^2) = √((-7)^2 +6^2) = √(49 +36)

... d = √85

The distance between the two points is √85.

Answer:

<C =120

Step-by-step explanation:

Since the figure in inscribed in the circle, <A = <C  and <B = <D

<B= <D

2x-1=3x-59

Subtract 2x from each side

2x-2x-1=3x-2x-59

-1= x-59

Add 59 to each side

-1+59 = x-59+59

58 =x

<A = 2x+4

<A= 2(58) +4

    = 116+4

<A =120

<C = <A

<C =120

Answer:

-5+√3i  is the given root so -5-√3i  must be the other root

Step-by-step explanation:

We know that complex roots must come in pairs. The pairs are complex conjugates.  (a+bi)  and (a-bi)

You are missing a sign between -5 and the square root

So if - 5+ sqrt(3) i  is a root, then -5 - sqrt(3) i   must be a root  

if -5 - sqrt(3)i   is a root, then -5 + sqrt(3)i   must be a root.

I will assume you missed a + sign

-5+√3i  is the given root so -5-√3i  must be the other root
