what information is necessary to prove two triangles are similar by SAS similarity thereom?​

Answer:

y=3x+10

Step-by-step explanation:

When two lines are parallel they are going to have the same slope which is 3x. The only thing we need to find is the y intercept based on the point they say the equation passes. to do this you take away the y intercept of the equation that we have and replace x with -2 and the subtract 4 to the side with the y.. now we have 4-y=-6 Then we solve for y and get y=10 which is the y intercept of the equation that is parallel to y=3x=1 and it passes (-2,4) Therefore the answer is y=3x+10

Answer:

The answer is 149

Step-by-step explanation:

So 2 oranges added up is 56 which is basically

x+x=56

2x=56

56/2=28

Each orange is worth 28

The 2 triangles multiplied are 81 which is

x*x=81

x^2=81

√81=9

Each watermelon Is worth 9

The 3 stars added up are

x+x+x=15

3x=15

15/3=5

Each star is worth 5

So the final equation if you plug in what we know

9+28*5

So orders of operations, (Parenthesis, exponents, etc.)

So multiplication is first

28*5=140

And add

140+9=149

So final answer 149

Step-by-step explanation:

Answer:

No, with the guides in between the two ladders, it is not possible for the lower ends of the ladder to be up to 12 feet apart

Step-by-step explanation:

The given parameters are;

The length of two sides of the step ladder = 12 feet

The maximum value allowable for the included angle between the two 12 feet ladders = 58°

Therefore, the maximum value of the third side facing the included angle is given as follows;

let "a" represent the maximum value of the third side formed by the distance apart of the lower end of the ladder, by cosine rule, we have;

a² = 12² + 12² - 2 × 12 × 12 × cos(58°) = 135.383251901

∴ a = √(12² + 12² - 2 × 12 × 12 × cos(58°)) ≈ 11.64

The maximum value of the third side formed by the distance apart of the lower end of the ladder = a ≈ 11.64 feet < 12 feet

Therefore, it is not possible for the lower ends of the ladder to be up to 12 feet apart.

Answer: Length ≥ 6 feet

Step-by-step explanation:

The area of a rectangle= length × width

In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.

The inequality that describes the possible lengths (in feet) of the stage would be:

Length × Width ≥ 24

Length × 4 ≥ 24

Length ≥ 24/4

Length ≥ 6

Therefore, the length must be at most 6 feet.

Answer:

[tex]2.9 cm^2[/tex]

Step-by-step explanation:

Given,

Angle of sector = 30°

Radius of circle, r = 8 cm

Area of the shaded region, A =?

The diagram is attached below.

Now,

Area of shaded region = Area of sector - Area of triangle

Area of triangle = [tex]\frac{1}{2}\times base \times height[/tex]

We know that,

[tex]\sin \theta = \dfrac{P}{H}[/tex]

[tex]\sin 30^\circ= \dfrac{P}{8}[/tex]

[tex]P = \dfrac{8}{2}[/tex]

[tex]P = 4\ cm[/tex]

And

[tex]\cos \theta =\dfrac{B}{H}[/tex]

[tex]\cos 30^\circ = \dfrac{B}{8}[/tex]

[tex]B = \dfrac{8\times \sqrt{3}}{2}[/tex]

[tex]B = 4\sqrt 3[/tex]

Area of sector = [tex]\dfrac{\theta}{360^\circ}\times \pi r^2[/tex]

Area of sector =  [tex]\dfrac{30^\circ}{360^\circ}\times \pi \times 8^2[/tex]

                        = 16.75 cm^2

Area of triangle = [tex]\dfrac{1}{2} \times 4\sqrt 3 \times 4[/tex]

                          = 13.85 cm^2

Area of shaded region = 16.75 - 13.85

                                      = [tex]2.9 cm^2[/tex]

Answer:

Step-by-step explanation:

Answer:

option D

Step-by-step explanation:

[tex]\sqrt{10x+50}=x+5\\\\(\sqrt{10x+50})^2=(x+5)^2\\\\10x+50=x^2+10x+25\\\\0=x^2+10x-10x+25-50\\\\0=x^2-25\\\\0=(x-5)(x+5)\\\\x=5\\\\x=-5[/tex]

now trying for the original equation

[tex]\sqrt{10(5)+50}=5+5\\\\\sqrt{50+50}=10\\\\\sqrt{100}=10\\\\10=10[/tex]

and

[tex]\sqrt{10(-5)+50}=-5+5\\\\\sqrt{-50+50}=0\\\\\sqrt{0}=0\\\\0=0[/tex]

so it's option D

It should be C can u help me with one i posted????

The value of the expression (x³+16) ÷4 is equal to 12. The correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is (x³+16) ÷4. The value of x is equal to 2. The expression will be solved as below,

E = (x³+16) / 4

E = 2³ + 16 / 4

E = 8 + 16 / 4

E = 8 + 4

E = 12

Step-by-step explanation:

Answer: x = 2 and y = 5

Step-by-step explanation:

y = 2x + 1

3x + y = 11

Substitute

3x + (2x + 1) = 11

5x + 1 = 11

Subtract both sides by 1

5x = 10

Divide both sides by 5

x = 2

y = 2x + 1

Substitute

y = 2 (2) + 1

y = 4 + 1

y = 5
