PEMDAS

Step-by-step explanation:

Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.

Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3

Then, go to your exponents. Since we don't have any, we skip this step.

Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.

Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.

The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.

2+5=7.

Answer:

the other two sides are 31.11 feet and 31.11 feet

Step-by-step explanation:

since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.

A right triangle is formed by a line from its peak down & perpendicular to

the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.

cos 50 = 20/x

0.6428 = 20/x

x = 31.11 feet

Answer:

x = 15

Step-by-step explanation:

2.5x + 3.5x = 90

6x = 90

x = 15

Step-by-step explanation:

Answer: 36.9

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos or Tan.

To work out which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.

As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.

So first you would have to write:

Tanθ=3/4

Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.

θ=Tan-1 3/4

To find the answer you would have to put it in your calculator.

θ=36.9

Answer:

72.25

Step-by-step explanation:

12.5 x 8.5 = 106.25

5 x 6.75 = 33.75

106.25- 33.75 = 72.25

Answer: H

Step-by-step explanation:

You're tryna find the area of the wall

Which is the whole surface area minus the door's area

Whole surface area = 8.5 x 12.5 = 106.25

Door area = 5 x 6.75 = 33.75

106.25-33.75 = 72.5 ft^2

V(t) = 25000(0.86) t

Step-by-step explanation:

You wont turn 14% into a multiplier (1.14 - multiplier) becuase the value decreases not increases so you do 100% - 14% to get 86% and divide by 100 to get 0.86...that's the value that goes in the brackets

Penjelasan langkah demi langkah:

Mode kumpulan data ditentukan oleh frekuensi atau berapa kali nilai terjadi pada kumpulan data. Nilai dengan jumlah kemunculan tertinggi disebut mode. Jika hanya satu nilai yang memiliki frekuensi tertinggi, itu disebut unimodal; jika dua nilai, maka itu disebut bimodal.

Nilai rata-rata kumpulan data, mengacu pada nilai rata-rata data. Dihitung sebagai jumlah data dibagi dengan Jumlah sampel dalam data.

Rata-rata = Σx / n

Given:

Triangle 1 has vertices at (A,B), (C,D), and (E,F).

Triangle 2 has vertices at (A+1,B+3), (C+1,D+3), and (E+1,F+3).

To find:

The conclusion about the triangle 2.

Solution:

From the given information it is clear that the x-coordinates of the vertices of triangle 2 are 1 more than the x-coordinates of the vertices of triangle 1.

Similarly, the y-coordinates of the vertices of triangle 2 are 3 more than the y-coordinates of the vertices of triangle 1.

So, the rule of translation is:

[tex](x,y)\to (x+1,y+3)[/tex]

It means the triangle 1 is shifted 1 unit right and 3 units up to get the triangle 2.

Therefore, triangle 2 is congruent to triangle 1 and triangle 2 is the translation of triangle 1 by 1 unit right and 3 units up.

Answer:

9

Step-by-step explanation:

Answer:

( 1 ), ( 3 ), ( 9 )

Step-by-step explanation:

Every time you add one to a digit (which is the same as adding 10, 100, 1000, etc) you get a number that is one more than a multiple of 9, so you have to subtract one from the number, which brings the sum of the digits back to 9.

Answer:

42.43 feets

Step-by-step explanation:

Given :

(Height of house / shadow of house) = (height of person / shadow of person)

(height of house / 65) = (4.8 / 7.2)

Cross multiply

Height of house * 7.2 = 4.7 * 65

Height of house = 305.5 / 7.2

Height of house = 42.43 feets

Answer:

Step-by-step explanation:

[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]

Take cube,

[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]

x + 4 = - (2x + 8)

x +4 = 2x *(-1) + 8 *(-1)

x+ 4 = -2x - 8

x +2x+4 = - 8

3x + 4 = - 8

      3x = - 8 -4

      3x = -12

        x = -12/3

x = -4

Answer:

2x^2 + x + 4

Step-by-step explanation:

Use Polynomial division.

The value after divide will be;

⇒ 2x² + x + 4

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)

Now,

Since, The expression is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)

Divide the expression as;

⇒ 3x + 7 ) 6x³ + 17x² + 19x + 28 ( 2x² + x + 4

               6x³ + 14x²

             -       -

           ----------------------

                        3x² + 19x

                        3x² + 7x

                      -       -

                    --------------------

                              12x + 28

                              12x + 28

                            -       -

                           -------------------

                                0

Thus, The solution is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7) = (2x² + x + 4)

Answer:

D

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan30° = [tex]\frac{\sqrt{3} }{3}[/tex] , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{7}[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] ( cross- multiply )

3x = 7[tex]\sqrt{3}[/tex] ( divide both sides by 3 )

x = [tex]\frac{7\sqrt{3} }{3}[/tex] → D
