Answer:

Ariel will be at an elevation of -3 meters.

Step-by-step explanation:

We have been given that Eric is swimming along the surface of the sea. He uses positive numbers to represent elevations above the surface of the sea and negative numbers to represent depths under the surface of the sea.

Since Eric is swimming along the surface of the sea, so his elevation will be 0.

As we are told that Mark is sitting above Eric and Eric uses positive number for elevation above surface of the sea, so Mark's elevation will be positive.

As we are told that Ariel is diving below Eric and Eric uses negative number for elevation below surface of the sea, so Ariel's elevation will be negative.

Therefore, Ariel will be at an elevation of -3 meters.

Which are true?
Tanzania [10]

Answers:

  1. True. All states have a different approach to collecting revenue, which is money they spend on government programs. Most states have income taxes, but a state like Florida doesn't have income taxes. Instead they rely on sales taxes and property taxes. The general rule is that if one tax is missing, then chances are the other tax rates are higher to make up the lack of funds (that the missing taxes would provide).
  2. False. States vary in sales tax rates. For instance, Alabama's sales tax is 4% while Arkansas is 6.5%
  3. True. You can do an online search of "states without sales tax" to find sources to help confirm this. Keep in mind that while the state overall does not impose sales tax, this does not mean the city and/or county governments won't impose sales tax. Unfortunately it's hard to escape taxes and sales tax is just one of those inevitable things.
  4. True. As mentioned in problem 3, local governments (city and/or county) tend to impose taxes of their own on top of state sales taxes. Sales taxes fund state programs while local taxes fund local programs. Though some local government programs will use state or federal dollars.

Solve: y = 2x. y = -x+3. Write the coordinates (__, __)
romanna [79]

Answer:

(1,2)

Step-by-step explanation:

y = 2x. y = -x+3

Set the two equations equal

2x = -x+3

Add x to each side

2x+x = -x+x+3

3x = 3

Divide by 3

3x/3 = 3/3

x = 1

Now find y

y =2x = 2(1) = 2

(1,2)

Find the product of √3 and 5√3 in simplest form. Also, determine whether the
pshichka [43]

The product of √3 and 5√3  in its simplest form is 15.

<h3>What is a rational number?</h3>

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

To determine the product of √3 and 5√3

So, (√3 )(5√3)

⇒ 5 (√3 )(√3 )

⇒ 5(3)

⇒ 15

The result is rational because 15, can be expressed as a ratio of two integers can be 15/1 of two integers, a numerator 15, and denominator 1 ( which is a non-zero).

Thus, the result is rational.
