Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution and that’s called inconsistent system of equations, and it has no solution. The third graph above, "Case 3"

Rewrite the following without an exponent. 6^-2<br> Please answer ASAP!
julia-pushkina [17]

Answer:

Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

Step-by-step explanation:

We need to rewrite the following without an exponent. 6^{-2}

We need to solve the exponent to find the result.

We know the exponent rule: a^{-b}=\frac{1}{a^b}

Now using this rule to solve the equation:

6^{-2}\\=\frac{1}{6^2}\\We \:know \:that\:6^2 = 6\times 6=36\\=\frac{1}{36}

So, Rewriting 6^{-2} without an exponent we get \mathbf{\frac{1}{36}}

Katie is playing a game using a 26-card deck that contains the black suits of the cards, which are 13 clubs and 13 spades. She c
Vladimir [108]

Answer:

The probability that Katie will draw a face card on her next turn is 3/13, or approximately 23%.

Step-by-step explanation:

In a regular deck, there are four suits (clubs, spades, hearts and diamonds).  Each suit has 13 cards that go from 2 - 10 plus the Ace, King, Queen and Jack.  Since Katie is playing using a 26-card deck of only two suits, then there are only two kings, two queens and two jacks in the entire deck.  In order to find probability, we form a fraction where the denominator is the total number of outcomes, in this case 26, and the numerator is the number of desired outcomes, in this case the total number of face cards in the deck - 6.  So, the probability that Katie will choose a face card on the next turn is 6/26, which simplifies to 3/13 in lowest terms.

Is 90° an acute angle, right angle, obtuse<br> angle, or straight angle?
VashaNatasha [74]

Answer:

90 degrees is a right angle.

Step-by-step explanation:

|_

^ That would be a 90 degrees angle.

|

|

|____

|___|____________

Imagine this is a graph, that little square of the right would represent 90 degrees.

Angles less than 90 are acute angles, angles over 90 but under 180 degrees would be obtuse, and angles that are equal to 180 degrees are straight.
