Answer:

4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.

Explanation:

It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.

Let the total number employees be e.

Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.

e < 24

Multiply 4 both sides.

ex 4 < 24×4

3e < 96

Divide both sides by 3.

e < 32

Therefore the value of e is less than 32.

In a number line as we approach towards left the the value of integers decreases.

Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.

Since 32 is not included in the solution set, therefore there is an open circle on 32.

A grocer stacks oranges in a four-sided pyramid that is 6 layers high. Solve for the number of oranges in the pile.
Vlada [557]
Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25 
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
                                                               = 91 oranges

Which has a greater biotic potential- humans or mice? Why?
Ganezh [65]
Nice because : Biotic potential is the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. An organism’s rate of reproduction and the size of each litter are the primary determining factors for biotic potential.

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex
OLEGan [10]

Answer: From the question,the correct order of how hearing works is listed below:

--> sound wave is generated from hitting a key on a piano,

--> Incus moves,

--> Stapes moves,

--> Sound wave enters inner ear,

--> Fluid in the cochlea moves,

--> Fluid wave moves across Organ of corti based on frequency,

--> Ions enter hair cells,

--> hair cells bend,

--> auditory nerve transmits the signal to the auditory cortex,

--> auditory cortex recognizes the sounds.

Explanation:

In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:

--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)

--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).

--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).

To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.

As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.

In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.
