can someone plz help me with this math equation!

Answer:

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}[/tex]

Step-by-step explanation:

Simplificación de expresiones algebraicas

Tenemos la expresión:

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}[/tex]

La división de fracciones suele manejarse mejor utilizando la multiplicación del inverso del denominador. Es decir, para dividir la fracción a/b entre la fracción c/d se multiplica a/b*d/c para resultar (a*d)/(b*c).

Apliquemos lo anterior al problema en consideración:

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{3m^2n^2}{5(m+n)}\cdot \frac{10(m+n)}{12m^4n}[/tex]

Multiplicamos los coeficientes en el numerador y denominador y eliminamos el factor (m+n):

[tex]=\displaystyle \frac{30m^2n^2}{60m^4n}[/tex]

La potencia 2 de la m se simplifica con la potencia 4 y la potencia 2 de la n se simplifica con la potencia 1. Igualmente se simplifica la fracción numérica dividiendo entre 30:

[tex]\boxed{\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}}[/tex]

Answer:

  (81√15)/4 ≈ 78.43 cm²

Step-by-step explanation:

It can help to draw a diagram.

The base angle at the side of length 6 can be found using the Law of Cosines. Its opposite side is of length 8, and the two adjacent sides are of length 6 and 7. So, we have ...

  8² = 6² +7² -2·6·7·cos(α)

  cos(α) = (36+49-64)/(84) = 1/4

  α = arccos(1/4) ≈ 75.522°

Then the height of the trapezium is ...

  6·sin(75.522°) ≈ 5.80948 . . . . cm

__

The area of the trapezium is given by the formula ...

  A = 1/2(b1 +b2)h

  A = (1/2)(17 +10)(5.80948) . . . . cm²

  A ≈ 78.43 cm²

__

Of course, sin(arccos(1/4)) = (√15)/4, so the exact formulation of the area is ...

  A = (81√15)/4 cm²

Answer:

Translated up by 2, translated to the right by 3

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

3/7r + 5/8s

r = 14

s = 8

3/7 x 14 + 5/8 x 8

3/7 x 14 = 6

5/8 x 8 = 5

6 + 5 = 11

ok so it's like the 3/7 and 5/8 are fractions so you just multiply each one by the number their next you which in this case is r and s so it's like you're just multiplying a fraction and a number. does that make since?

Answer:

This team can form 400 pretzels in one hour

Step-by-step explanation:

How many pretzels in 9 minutes?

5(12)=60

Solve as proportion

60 pretzels = 9 minutes

x    pretzels = 60 minutes

60(60)=9x

3600=9x

Divide both sides by 9

x= 400 pretzels

This team can form 400 pretzels in 1 hour

Answer:

this team can form 30 pretzels in 1 hour

Step-by-step explanation:

60 minutes are in a hour, and 60 divided by 9 is 6.6. So that means you would have to use 6. So 9 x 6 equals 54. Now do 5 x 6 and that would equal 30.

Step-by-step explanation:

Answer:

n= -34

Step-by-step explanation:

You want to get n alone so you would subtract 22 from both sides and -12 - 22 is -34

Answer:

-34

Step-by-step explanation:

22+n=-12

We move all terms to the left:

22+n-(-12)=0

We add all the numbers together, and all the variables

n+34=0

We move all terms containing n to the left, all other terms to the right

n=-34

Given Correct Statement is :- The data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. c. The data distribution is skewed to the right.

It is not possible for a data distribution to be both symmetric and skewed at the same time, as these are mutually exclusive characteristics.

A symmetric distribution is one in which the data is evenly distributed around the mean, with the left and right sides of the distribution being mirror images of each other.

A skewed distribution is one in which the data is not evenly distributed around the mean, with one tail of the distribution being longer than the other.

Based on the given options, only one statement can be true.

Option (c) states that the data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. Therefore, the correct statement is:

c. The data distribution is skewed to the right.

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

2/8 is equal to 1/4.

Now lets just say that the entire circle is 100%, or completely filled.

1/4 of 100 is 25. Then since it's already in terms of one hundred, we can say that 2/8 of a circle is 25% of it.

Answer: 1/4

Step-by-step explanation: 1/8 is half of 1/4 and 2/8 if simplified is 1/4

Answer:

Step-by-step explanation:

We can use the formula [ y2-y1/x2-x1 ] to solve.

Answer:

The answer is    

Step-by-step explanation:

use system of equations and substitution.

to solve this equation, one variable needs to be cancelled out to solve for the other.

[tex]-5y+4y=4\\-7y-10x=-10\\[/tex]

looking at this problem, we can manipulate -5 and -7 to equal 35 and -35 to get rid of the variable x to solve for y.

[tex]-7(-5y+4x=4)\\5(-7y-10x=-10)\\\\35y-28x=-28\\-35y-50x=-50[/tex]

with this, we can cancel out 35x and -35x.

[tex]-28x=-28\\-50x=-50[/tex]

manipulate the equation to equal x.

[tex]x=1\\x=1.[/tex]

plug 1 for x back into one of the equations to solve for y.

[tex]-5y+4(1)=4\\-5y+4=4\\-5y=0\\y=0[/tex]

therefore, (1,0)

Find the diagram attached.

From the right triangle XYZ:

XY is the hypotenuse

XZ and YZ are opposite and adjacent

To get value of tan(Y), we will use the SOH, CAH, TOA, trigonometry identity.

According to TOA:

Tan(Y) = XZ/ZY

First let us get XZ

Using SOH

SinY = opp/hyp = XZ/XY

SinY = XZ/4

Sin30 = XZ/4

XZ = 4sin30

XZ = 4(0.5)

XZ = 2units

Next is to get ZY:

Using Pythagoras theorem:

ZY²+XZ² = XY²

ZY² = XY²-XZ²

ZY² = 4²-2²

ZY²  = 16-4

ZY²  = 12

ZY = √12

ZY = √4*3

ZY = 2√3

Solve for tan(Y):

Since Tan(Y) = XZ/ZY

Tan(Y) = 2/2√3

Tan(Y) = 1/√3

Rationalize

Tan(Y) = 1/√3*√3/√3

Tan(Y) = √3/√9

Tan(Y) = √3/3

Hence the correct option is A. StartFraction StartRoot 3 EndRoot Over 3 EndFraction
