yes 831 is divisible by 3

One way I know this is because when adding all the digits in the number you get 12 which is divisible by 3

Also if you do divide 831 ÷ 3 it would equal 277

Answer:

MNO ~ OPQ by AAA (Angle angle angle)

Step-by-step explanation:

1. angle POQ is equal to angle NOM because they are both vertical angles

2. angle OPQ and angle OMN are equal because parallel lines cut by a transversal form congruent alternate interior angles.

3. angle PQO and angle ONM are equal becase of the same reason as reason 2 (parallel lines cut by a transversal form congruent alternate interior angles. )

4. triangles MNO ~ OPQ through AAA (angle angle angle)

Answer: 225 tiles

Step-by-step explanation:

Side of tile = 20 cm = 0.2 m

Side of bathroom = 3 m

Area of tile = 0.04 m²

Area of bathroom = 9 m²

No. of tiles = Ar (bathroom) / Ar (tile)

= 9 / 0.04

= 9 x 25

= 225 tiles

Answer:

The value of the expression for x=3 is 51

Step-by-step explanation:

Evaluating expressions

To evaluate a given expression, we simply substitute the value of the variables and complete the operations.

The expression to evaluate is:

P=3(2+5x)

We will evaluate for x=3:

P=3(2+5*3)

The product must be done first:

P=3(2+15)=3*17=51

The value of the expression for x=3 is 51

Answer:

The original price of the toaster is 2000

Step-by-step explanation:

Given: Toaster price = 2240

VAT = 12%

VAT amount = ?(I'll include this one)

Assume the original price be x.

Let the original price be x

Then,  x + 12% of x = 2240

x+12/100x x = 2240
100x+12x/ 100= 2240

112x/100=2240

112x = 2240 x 100 ⇒ 224000

x = 224000/112

x = 2000.

So, the original price of toaster = Rs. 2000.

The VAT amount = 2240 - 2000 ⇒ Rs. 240.

The VAT amount is Rs. 240.

Answer:

discount = 25%

Step-by-step explanation:

discount is calculated as [tex]\frac{reduction}{original}[/tex] × 100%

reduction = 2800 - 2100 = 700

discount = [tex]\frac{700}{2800}[/tex] × 100%  = 0.25 × 100% = 25%

Answer:

she has 12 - D quarters.

She has 24 (12-D) cents in quarters

Step-by-step explanation:

You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.

If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.

and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.

Answer:

she has 12 - D quarters.

Answer:

trapezoid

Step-by-step explanation:

since the figure has only 1 pair of parallel sides then it is a trapezoid

Answer:

rhombus

Step-by-step explanation:

Answer:  see proof below

Step-by-step explanation:

Use the Cofunction Identity: sin (90 - A) = cos (A)

Use the Double Angle Identity: sin(2A) = 2 sinA cosA

Use the Triple Angle Identity: cos (3A) = 4cos³A - 3cosA

Use the Zero Product Property: If a · b = 0, then a = 0 or b = 0

Use Pythagorean Identity: cos²A + sin²A = 1  → cos²A = 1 - sin²A

Use Quadratic Formula:   [tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Proof LHS → RHS:

Assumption:                 Let A = 18°

Multiplication:               then 5A = 5(18°)

                                         →   5A = 90°

Expand:                         2A + 3A = 90°

                                  →  2A = 90° - 3A

Apply sin:                  sin (2A) = sin (90° - 3A)

Cofunction:               sin (2A) = cos (3A)

Double Angle:          2 sinA cos A = cos (3A)

Triple Angle:             2 sin A cos A = 4cos³A - 3cos A

                             → -4cos³A + 3cos A + 2sinA cos A = 0

Factor:                      cos A(-4cos² A + 3 + 2sin A) = 0

Zero Product Property: cos A = 0    or   -4cos² A + 3 + 2sin A = 0

                                             ↓

                                     Disregard (since cos A ≠ 0)

Pythagorean:                                           -4cos² A + 3 + 2sin A = 0

                                                            →  -4(1 - sin² A) + 3 + 2sin A = 0

                                                           →   -4 + 4sin² A + 3 + 2sin A = 0

Simplify:             4sin² A + 2sin A - 1 = 0

                      a=4         b=2      c= -1

[tex]\text{Quadratic Formula:}\qquad \sin A=\dfrac{-(2)\pm \sqrt{2^2-4(4)(-1)}}{2(4)}[/tex]

                                              [tex]=\dfrac{-2\pm \sqrt{4+16}}{8}[/tex]

                                              [tex]=\dfrac{-2\pm \sqrt{20}}{8}[/tex]

                                              [tex]=\dfrac{-2\pm 2\sqrt{5}}{2(4)}[/tex]

                                             [tex]=\dfrac{-1\pm \sqrt{5}}{4}[/tex]

                                             [tex]=\dfrac{ \sqrt{5}-1}{4}[/tex]

[tex]\text{Substitute A = 18:}\qquad \sin 18=\dfrac{ \sqrt{5}-1}{4}[/tex]

Answer: The answer is C

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

(g - f)(x)

= g(x) - f(x)

= log(x - 3) + 6 - ([tex]\sqrt[3]{12x+1}[/tex] + 4)

= log(x - 3) + 6 - [tex]\sqrt[3]{12x+1}[/tex] - 4 ← collect like terms

= log(x - 3) - [tex]\sqrt[3]{12x+1}[/tex] + 2

Value of the given function[tex](g-f)x = log(x-3)-\sqrt[3]{12x+1} +2[/tex].

" Function is defined as the relation between the given variables is such that every input has exactly one output each."

According to the question,

Given functions are,

[tex]f(x) = \sqrt[3]{12x+1} +4\\\\g(x) = log(x-3) +6[/tex]

Substitute the value in the function (g -f)x we get,

[tex](g-f)x = g(x) -f(x)[/tex]

             [tex]= log(x-3) + 6 -( \sqrt[3]{12x+1} +4)\\\\= log(x-3) + 6 -\sqrt[3]{12x+1} -4\\\\= log(x-3) -\sqrt[3]{12x+1} +2[/tex]

Hence, Option(B) is the correct answer.

Make sure your calculator is in Degree mode.

The number of apple in each basket is as follows:

First basket = 25 apples

Second basket = 37 apples

Third basket = 16 apples

Fourth basket = 29 apples

Fifth basket = 13 apples

total apples = 120

let

the number of apples in the first basket = a

the number of apples in the second basket = b

the number of apples in the third basket = c

the number of apples in the fourth basket = d

the number of apples in the fifth basket = e

Therefore,

a + b = 62

b + c = 53

c + d = 45

d + e = 42

a + b + c + d + e = 120

62 + 45 + e = 120

e = 120 - 62 - 45

e = 13

d = 42 - 13

d = 29

c = 45 - 29

c = 16

b = 53 - 16

b = 37

a = 62 - 37

a = 25

Therefore,

the number of apples in the first basket = 25

the number of apples in the second basket = 37

the number of apples in the third basket = 16

the number of apples in the fourth basket = 29

the number of apples in the fifth basket = 13
