Choose one of the three elements of African culture in colonial North America: food and farming, storytelling, or music and dance. Describe one way African culture influenced your chosen element in the colonies. Explain one way this influence can still be seen today?

Answers

Answer:

Music and dance. It's easier in today's society to see black influence over popular music genres, however, this most likely stemmed from African culture, and as you said, in colonial North America. The colonials who enslaved the Africans most likely (i keep using this term so that you can confirm with your own teachings)  were influenced by their customs and music (which can include dance) and attempted to integrate it into their own culture. This would trickle down into the future generations through black-dominated genres, such as hip-hop, rap, drill, and dances, such as break dancing, hip-hop (dancing), and the sort.

The ratio of men to women working for a company is 7 to 5. If there are 336 employees total, how many women work for the company?

please answer soon as possiblee!!!

Answers

Answer:  140

==========================================================

Explanation:

m = number of men

w = number of women

The ratio of men to women is 7 to 5, meaning that m/w = 7/5

Cross multiply to get 5m = 7w.

Then divide both sides by 5 to end up with m = 7w/5 which is the same as m = 1.4w

We'll use this equation later.

------------------

Since there are 336 total workers, we know that:

m+w = 336

1.4w+w = 336 .... replace m with 1.4w

2.4w = 336

w = 336/(2.4)

w = 140 women work at the company

and m = 1.4*w = 1.4*140 = 196 men work at the company as well.

------------------

Checking the answer:

m+w = 196+140 = 336

m/w = 196/140 = (7*28)/(5*28) = 7/5

This helps confirm we have the correct value of w.

A company offers you a salary of $2,000 per month plus a signing bonus of $10,000. What is the yearly salary rate? PLEASE HELP!!!!

Answers

Since yearly, without the bonus, you would make a certain amount by multiplying $2,000 to a year, which is 12 months.

2000 × 12 = 24,000 a year.

That would be $24,000 a year.

Next, we can add 10,000 to the amount, since you are not getting paid that much for a year. It is just a "...plus...", a bonus.

24,000 + 10,000 = 34000

Therefore, the yearly salary rate will be $34,000 a year.

Answers:What is that positive integer?  400What is the value of the positive root?  20What is the value of the negative root?  -20

=======================================================

Explanation:

Let x be the unknown positive integer.

The square roots of x are [tex]\sqrt{x}[/tex] and [tex]-\sqrt{x}[/tex], representing the positive and negative square roots respectively.

Taking the difference of those means we subtract:

[tex]\text{PositiveRoot}-\text{NegativeRoot} = \sqrt{x} - (-\sqrt{x}) = \sqrt{x}+\sqrt{x} = 2\sqrt{x}[/tex]

Set that equal to 40 and solve for x

[tex]2\sqrt{x} = 40\\\\\sqrt{x} = 40/2\\\\\sqrt{x} = 20\\\\x = 20^2\\\\x = 400[/tex]

Therefore, the integer we're after is 400.

The positive square root of such is [tex]\sqrt{x} = \sqrt{400} = \sqrt{20^2} = 20[/tex]

And the negative square root is [tex]-\sqrt{x} = -\sqrt{400} = -\sqrt{20^2} = -20[/tex]

The difference of which is:

(Positive Root) - (Negative Root) = 20-(-20) = 20+20 = 40

This helps confirm the answers.
