Answer:

Step-by-step explanation:
This question utilizes combining like terms and common denominators. First you have to convert both terms including "a" to have a denominator of 8. You would do this by multiplying both the numerator, and the denominator by the same value. This value in the case of
would be 2, and in the case of
the value would be 2. This would result in the equation:
. Then simply combine like terms to get your final answer.
Having drawn one king, there are 3 kings remaining and a total of 51 cards. Therefore the probability of drawing another king is 3/51 = 1/17.
It would be: 6 ( 6- 4)
= 6 ( 2)
= 12
So, Your Answer would be 12
Hope this helps!
Answer:
Down
Step-by-step explanation:
As the lines of the parabola point down, the parabola opens down.
Find the percent of the circle
r=radius of circle
then r=1/2 of the diagonal of the square
use some pythagoran theorme
45,45,90 triangle
(r√2)/2=1/2 of a side
r√2 is one side
square it
2r²=square
area of circle is pir²
percent it is is
square/circle=
(2r²)/(pir²)=
2/pi= about
0.636
about 64% that it is in the square
