Answer:

Option D.

Step-by-step explanation:

From the given figure it is clear that the three quadrilaterals on a coordinate grid are squares because all sides of each quadrilaterals are same and all interior angles are right angles.

Side length of square M = 2 units

Side length of square N = 2 units

Side length of square O = 4 units

The corresponding sides of congruent figures are congruent. So,

Square M ≅ Square N

The corresponding sides of similar figures are proportional. So,

Square M $\sim$ Square N

Square M $\sim$ Square O

Square N $\sim$ Square O

M and O are similar but not congruent.

Therefore, the correct option is D.

Answer:

D. M and O are similar but not congruent.

Step-by-step explanation:

To begin, let's eliminate some options.

It can't be <em>A. M and O are similar and congruent</em> because M and O aren't congruent because they are different sizes. It cannot be <em>B. O and N are similar and congruent</em> because they aren't congruent since they're different sizes. Lastly, it cannot be <em>C. M and N are similar but not congruent, </em>because these two are actually congruent.

<u>Therefore, the correct answer is D. M and O are similar but not congruent. </u>

A compressed air tank carried by scuba divers has a volume of 8.00 L and a pressure of 141 atm at 22.0°C. What is the volume (in

weqwewe [10]

Answer:

Volume of air in the tank =1,044 Liter

Step-by-step explanation:

Given:

Tank volume = 8 Liter

Pressure = 141 atm

Temperature = 22°C = 273° + 20° = 295° K

Find:

Volume of air in the tank = ?

Computation:

$\frac{Pressure\times Tank\ volume}{Tempreture} =\frac{Pressure\times Air\ volume}{Tempreture}\\\\\frac{141\times 8}{295} =\frac{1\times Air\ volume}{273.15}\\\\\frac{1,128}{295} =\frac{Air\ volume}{273.15}\\\\Air\ volume=1,044.45$

Volume of air in the tank =1,044 Liter

What product is positive ?

<h3>Answer: Choice D</h3>

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

Explanation:

The long way to do this is to multiply all the fractions out by hand, or use a calculator to make shorter work of this.

The shortest way is to simply count how many negative signs each expression has.

The rule is: if there are an even number of negative signs, then the product will be positive. Otherwise, the product is negative.

For choice A, we have 3 negative signs. The result (whatever number it is) is negative. Choice B is a similar story. Choice C is also negative because we have 1 negative sign. Choices A through C have an odd number of negative signs.

Only choice D has an even number of negative signs. The two negatives multiply to cancel to a positive. The negative is like undoing the positive. So two negatives just undo each other. This is why the multiplied version of choice D will be some positive number.

Or you can think of it as opposites. If you are looking up (positive direction) and say "do the opposite" then you must look down (negative direction). Then if you say "do the opposite", then you must look back up in the positive direction.
