Two right triangles are similar and have areas of 36 m and 144 m². If the hypotenuse of the larger
triangle is 30 m long, what is the length of the hypotenuse of the smaller triangle?

Answers

Answer 1

Answer: 18

Step-by-step explanation:

Find the scale factor: 144/36= 4. But scale factor of area is r^2=4=> r= 2

Hypotenuse of small triangle is:

36/x=2 => x=18

Answers

Answer:

3, 20, 2, and 2.5

Step-by-step explanation:

For each question, they gave you an x and y value. If you substitute them into the equation and then solve for k, you get your answer.

On the first one, x is 12 and y is 1/4. If you put those into the equation they gave you y = k/x, you get 1/4 = k/12

3/12 is 1/4 so the first k is 3.

Second one y = k/x. x is 4 and is 5. So 5 = k/4

20/4 is 5, so the second k is 20.

What would be the best method to use in order to solve the following quadratic equation?
X^2 - 3x = 10

Answers

Answer:

Use the x method

Step-by-step explanation:

Move the 10 over to the other side and get x^2 - 3x -10 = 0 and solve by finding two numbers that add up to negative 3 but multiply to -10 which would be -5 and 2 so the binomials are (x-5)(x+2)

Answer:

x^2 - 3x = 10

Step-by-step explanation:

Move all terms to the left side.

Use the sum product pattern.

Factor (x-5)(x+2) = 0

Create two separate equations,

x - 5 = 0, and x + 2 = 0

Rearrange and isolate the variable.

x = 5

x = -2

X= [?]°

Answers

Answer:

X≈ 70.5°

Step-by-step explanation:

Using the cosine rule in Δ XYZ

cos X = [tex]\frac{y^2+z^2-x^2}{2yz}[/tex]

with x = 22, y = 20, z = 18 , then

cos X = [tex]\frac{202+18^2-22^2}{2(20)(18)}[/tex]

          = [tex]\frac{400+324-484}{720}[/tex]

          = [tex]\frac{240}{720}[/tex] , then

∠ X = [tex]cos^{-1}[/tex] ([tex]\frac{240}{720}[/tex] ) ≈ 70.5° ( to the nearest tenth )

show the steps

Answers

Answer:

y= -5/2x + 3/2

Step-by-step explanation:

(3,-6). y=mx+b or -6=-5/2 × 3+b, or solving for b: b=-6-(-5/2)(3). b=3/2.

(-1,4). y=mx+b or 4=-5/2 × -1+b, or solving for b: b=4-(-5/2)(-1). b=3/2.

Plugging in the two points, hence y= -5/2x + 3/2

Step-by-step explanation:

This is a special 45-degree right triangle. Two angles equal 45 degrees, and then there is a right triangle. In these triangles, the hypotenuse is equal to [tex]k*\sqrt{2}[/tex] where k is equal to the legs (a and b). So, to find the legs divide [tex]k*\sqrt{2}[/tex] by [tex]\sqrt{2}[/tex]. This equals 2, and since a and b are congruent both a and b equal 2.

How would I get the slope of this triangle?

Answers

Answer:

-4/3

Step-by-step explanation:

if the triangle is anchored at (0, 0) you come down

from point ( 0, 48) to point ( 36, 0) so the slope is

When the player blows into the mouthpiece, the column of air inside the instrument vibrates, and standing waves are produced. Although the acoustics of wind instruments is complicated, a simple description in terms of open and closed tubes can help in understanding the physical phenomena related to these instruments. For example, a flute can be described as an open-open pipe because a flutist covers the mouthpiece of the flute only partially.
