Answer:
We hear sounds because sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
Step-by-step explanation:
Answer:
undefined
Step-by-step explanation:
Here,
x1 = - 3
y1 = 6
x2 = - 3
y2 = 4
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 4 - 6 ) / ( - 3 - ( - 3 )
= - 2 / 0
= undefined
Answer: Read below.
Step-by-step explanation:

Let's take the first one.

Subtract 17

Divide by 3

---------------------------------------------------------------------------------------------
Now the second one.

Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.


---------------------------------------------------------------------------------------------
x has to be less than 10
x has to be greater than
or -2.66 approximately.
in the number line, make a hollow circle on
and draw an arrow up to
where, again, you have to make a hollow circle. The circles have to be hollow because neither
nor 10 are part of the answers.
X= 8.99981500..................
The answer would be 1:11, or 6:66. 1:11 is the simplified verison.
