How do you write 4.789x10^7 in standard form?

Answer:

(2x+5x)-6=50

          7x =56

              x=8

5>2, so 5 is the bigger one

5*8=40

the answer is 40

Perpendicular Transversal Theorem

If two lines are perpendicular to the same line, then the two perpendicular lines are parallel.

Given:

In a right angle triangle θ is an acute angle and [tex]\tan\theta =\dfrac{3}{5}[/tex].

To find:

The value of [tex]\cos \theta[/tex].

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

We have,

[tex]\tan\theta =\dfrac{3}{5}[/tex]

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

[tex]Hypotenuse=\sqrt{Perpendicular^2+base^2}[/tex]

[tex]Hypotenuse=\sqrt{(3x)^2+(5x)^2}[/tex]

[tex]Hypotenuse=\sqrt{9x^2+25x^2}[/tex]

[tex]Hypotenuse=\sqrt{34x^2}[/tex]

[tex]Hypotenuse=x\sqrt{34}[/tex]

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos \theta=\dfrac{5x}{x\sqrt{34}}[/tex]

[tex]\cos \theta=\dfrac{5}{\sqrt{34}}[/tex]

Therefore, the value of [tex]\cos \theta[/tex] is [tex]\dfrac{5}{\sqrt{34}}[/tex].

Answer:

Step-by-step explanation:

d

Answer:

No

Step-by-step explanation:

you can check with the pythagorean theory

[tex]8^{2}+9^{2} =12^{2}[/tex]

64 + 81 = 144

145 = 144

this is not true, therefore those side lengths do not make a right triangle.

Answer: 6

Step-by-step explanation: subtract 13 from 37, you get 24. divide 24 by 4.

Answer:

d should be correct

Step-by-step explanation:

why my answer beacuse i see 4in in the painted area

Answer:

8 meters

Step-by-step explanation:

To find the perimeter follow these steps:

1. add the lengths together (the longe sides) so add 3 meters and 3 meters you get 6 meters

2. add the widths together (the short sides) so add 1 meter and 1 meter you get 2 meters

3. add the total lengths and widths together (6 meters plus 2 meters) you get 8 meters

Have a fantastical day!

Answer:

-x + 39 = 31

Step-by-step explanation:

You would subtract 39 which would make -8. Then you would divide by -1 (x) and your answer is:

x = 8

Answer:

The equations 15 - n = 7, 4n = 32, and 64 : n = 8 have 8 as a solution.

Step-by-step explanation:

Each equation will have work shown below :

15 - n = 7

For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to subtract and the inverse operation of that is addition. Since the original operation is subtraction, we need to add it by a negative sign to each side. In order to isolate the variables, we have to add -7 to both sides.

  15 - n = 7

+ -7      + -7

   8 = n

The right side has a sum of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

4n = 32

For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to multiply and the inverse operation of that is division. In  order to isolate the variables, we have to divide 8 to both sides.

4n = 32

/4     /4

 n = 8

The left side has a quotient of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

This is a ratio which is basically just the operation of division. For this equation, we would need to isolate the variables by doing the inverse operation to both sides of the equation. Here in this equation, the operation is to divide and the inverse operation of that is multiplication. Since the original operation is division, we need to multiply it by the reciprocal to each side. In order to isolate the variables, we have to multiply 1/8 to both sides.

 64 : n = 8

* 1/8     * 1/8

  8 = n

The right side has a product of 0 so it doesn't require any value to the equation. As you can see in the equation, n equals to 8.

Answer:D

Step-by-step explanation:

Answer:

m∠1 = 70

Step-by-step explanation:

A line is 180 degrees

The angles of a triangle total to 180 degrees

180 - 101 = 79

79 + 31 = 110

180 - 110 = 70

Step-by-step explanation:

[tex]sum ~of ~3~angles ~of ~a~ triangle ~is ~180[/tex]

[tex]80+20+x=180[/tex]

[tex]x=missing ~angle[/tex]

[tex]100+x=180[/tex]

[tex]x=180-100=80[/tex]

[tex]So, x=80[/tex]
