Can Someone Please Solve These Problems For Me If You Could Do Step By Step That Would Rlly Help Me This

Answers

Answer 1

Answer:

7. about 41.8 degrees or 0.72972 radians (used [tex]sin^{-1} (\frac{4}{6} )[/tex], because the given leg is opposite from the angle)

8. about 50.4 degrees or 0.87946 radians (used [tex]tan^{-1} (\frac{29}{24} )[/tex])

9. about 12.8 degrees or 0.224 radians (used [tex]sin^{-1} (\frac{12}{54} )[/tex])

10. about 51.3 degrees or 0.8957 radians (used [tex]cos^{-1} (\frac{25}{40} )[/tex], given leg is opposite from angle)

Step-by-step explanation:

S.O.H.--C.A.H.--T.O.A

sine = opposite (to angle)/hypotenuse

cosine = adjacent (to angle)/hypotenuse

tangent = opposite (to angle)/adjacent (to angle)

I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!

6x+11=21 i dont know what x is! Help me plz

Answers

Answer:

x = 0.6

Step-by-step explanation:

6x + 11 = 21

subtract 11 from both sides

6x = 10

divide by 6 on both sides

x = 0.6

6x= 21-11
X= 10/6 and then simplify it
X= 5/3

4x + 5 = 17 what is the value of the x​

Answers

Answer:

x=3

Step-by-step explanation:

4x+5=17

    -5=-5

4x=12

divide both sides by 4

x=3

The solution of the equation 4x + 5 = 17 gives x equals to 3.

Given Equation:

4x + 5 = 17

Now, subtract 5 from both side of the equation is

4x + 5 - 5 = 17 - 5

Then, simplifying the expression

4x = 12

Now, divide both side of the equation by 4 as

4x/ 4= 12/4

x = 3

Therefore, the value of x is 3.

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

3x + 10 ≤ 30   be equation (1)

On simplifying , we get

Subtracting 10 on both sides , we get

3x ≤ ( 30 - 10 )

3x ≤ 20

Divide by 3 on both sides , we get

x ≤ 20/3

x ≤ 6.333

Therefore , the value of x is less than or equal to ( 20/3 )

Hence , the inequality is x ≤ 20/3

A. 29√3
B. 9√3

Answer:

D

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying each radical

[tex]\sqrt{27}[/tex]

= [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]

[tex]\sqrt{12}[/tex]

= [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]

[tex]\sqrt{48}[/tex]

= [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]

Then

3[tex]\sqrt{3}[/tex] - 2[tex]\sqrt{3}[/tex] + 4[tex]\sqrt{3}[/tex]
