Answers

Answer 1

The molarity of the solution that contains 87.75 g of NaCl in 500 mL of the solution is 3 M

What is molarity?

This is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

How to determine the mole of NaCl Mass of NaCl = 87.75 g ofMolar mass of NaCl = 23 + 35.5 = 58.5 g/mol Mole of NaCl =?

Mole = mass / molar mass

Mole of NaCl = 87.75 / 58.5

Mole of NaCl = 1.5 mole

How to determine the molarity Mole of NaCl = 1.5 mole Volume = 500 mL = 500 / 1000 = 0.5 L Molarity =?

Molarity = mole / Volume

Molarity = 1.5 / 0.5

Find the dimensions of a rectangle (in m) with perimeter 68 m whose area is as large as possible. (enter the dimensions as a comma-separated list.)

Answers

The dmension of the rectangle with perimeter of 68 m has the largest possible area as 17m by 17m.

Perimeter of a rectangle

perimeter of rectangle = 2(l + w)

where

l = lengthw = width

Therefore,

perimeter = 68 m

68 = 2l + 2w

l + w = 34

l = 34 - w

Hence, the largest possible area is at the amximum.

area = lw

area = w(34 - w)

area = 34w - w²

The maximum is at dA / dw = 0

Therefore,

34 - 2w  = 0

2w = 34

w = 34 / 2

w = 17

l + w = 34

l + 17 = 34

l = 34 - 17

l = 17

(WILL MARK BRAINLIEST!) If a student attends a non-credited high school, or in their case a homeschooling program, will they have to take the SAT/ACTs to be able to attend community college? Please answer explaining how a student such as this can get into college and the requirements they would need.

Answers

Answer:

So I turned homeschool not too long ago and you do need to the the SAT/ACT depending on which community college it is? If the high school or college offer ACT then the test you most likely need to take is the ACT. But if the test they offer is SAT then you should take that. Taking both of the SAT and ACT would only do better on your resume/aplication so it's really up to you. I plan to take both if I have the time. But I heard most people take the ACT. You should check what your community usually offer.

Hope this helps.

Explanation:

Answer:  college admissions is handled very similarly for homeschoolers as it is for traditionally schooled students. In fact, many admissions offices actively seek out homeschoolers. Admissions officers evaluate each student within the context of his/her own background and the opportunities they've had. There are, however, a few differences regarding how homeschoolers submit certain application materials. As a homeschooled student, your parent or primary teacher is responsible for creating your high school transcript and for sending it to your colleges. Parents have a few different options for going about this:

 1. Working under an umbrella school that produces official transcripts and diplomas

2. Creating their own transcript and diploma

3. Enlisting a service that specializes in transcript and diploma creation

4. Joining a homeschool group that produces professional transcripts and diplomas

Explanation:

Your transcript should include all of the following information:

Your name, the name of your homeschool (if applicable), address, and phone number

Your high school course list ordered by year (grades 9-12)

The institution where each class was taken (i.e. homeschool, online institution, community college)

The grade scale being used in your homeschool

Your overall GPA

Credits given per course (listed per semester and per year)

Expected graduation date

Parent signature with a date

Homeschoolers do not need a GED or a diploma to apply to college or qualify for financial aid; you just have to declare that your homeschool education meets state law requirements. Most homeschooled students choose not to take the GED if they have valid transcripts, as colleges will place the most emphasis on your transcript and standardized test scores. If you’re homeschooled through an online academy, virtual school, or organized homeschool program then they will award your diploma according to their own standards. If you’re homeschooled independently by your parents, then your parents have the option of issuing you a diploma if your transcripts indicate you’ve met the basic state requirements for graduation. When filling out the FAFSA, be sure to check “homeschooled” when it asks for your high school completion status. Even if your homeschool is administered through an umbrella organization, you should still check “homeschooled” instead of “high school diploma” to avoid any delays in the processing of your application.

A computer’s memory is composed of 8k words of 32 bits each. how many total bytes in memory?

Answers

The number of total bytes in memory is 32,000 bytes.

How many total bytes in memory?

We know that the memory is composed of 8k (or 8,000) words of 32 bits each.

To get the total memory, we just need to take the product between the number of words and the memory that each has.

This will give:

8,000*(32 bits) = 256,000 bits.

But we want this in bytes so we need to change the units, remember that:

1 bit = 0.125 byte.

Then we have:

256,000 bits = 256,000*( 0.125 byte) = 32,000 bytes.

The memory has 32,000 bytes in total.

The path of an autonomic nerve involves two nerve cells. One of them is located in the brain stem or spinal cord. It is connected by nerve fibers to another cell, located in a group of nerve cells (called autonomic ganglia). Nerve fibers from these ganglia connect with internal organs.
