Answer:

From Conditional Statements, there can be built a Tautology.

Step-by-step explanation:

According to the question, when the Hypothesis is True and the Conclusion is False, the result will be False. And that's correct.

But when Conditional Statement can be a Tautology, given the fact that not always a Conditional Statement will return the logic value of truth? Look at this example below:

1)James is from Orlando and He lives in Florida. Therefore, James is from Orlando.

2)James is from Orlando and He doesn't live in Florida. Therefore, James is from Orlando.

3)James is not from Orlando e He lives in Florida. Therefore, James is from Orlando

4)James is not from Orlando e He doesn't live in Florida. Therefore, James is from Orlando

What we have here above is symbolic for:

p∧q→p

And this is tautological, since no matter, we have on line 2 for p∧q, q being false it does not change the value for false, in any way for the whole proposition p∧q→p . What gives us a Tautology

This, p∧q→p can be rewritten as p∧q⇒p

Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.

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

<u>First, find the area of the circle. Here is the formula:</u>

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

<u>Then, you just do the math:</u>

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

mat deposited $2,000.00 in the bank. if the rate of simple interest was 10%, what was the amount of money mat had in the bank af
Mekhanik [1.2K]
Principal amount of money deposited by Mat in the bank = $2000
Rate of simple interest given by the bank = 10%
Number of years for which the money is kept in the bank = 5 years
As no money was withdrawn from the account, so
Amount after 5 years = Principal [1 + (Rate * Time)]
                                  = 2000 [ 1 + (10/100) * 5]
                                  = 2000 [ 1 + (1/2)]
                                 = 2000 * (3/2)
                                 = 1000 * 3
                                 = 3000 dollars
So the amount of money made by Mat after 5 years will be $3000.00
