Answer: x=4
Steps: (I am assuming your question has a typo in it and by "c" you meant "x")
The rational expression equals zero
only when the numerator equals 0 (the denominator cannot ever be zero):
and that happens only for x=4
Blood types all have different antigens. People can only receive blood with the same antigens as theirs. Type A and B both have different distinct antigens. But because AB blood contains both A and B it can take blood from both those types. However, people with AB blood can also receive Type O blood because it lacks antigens entirely. Therefore, that makes AB the universal receiver.
Answer:
61%
Step-by-step explanation:
Because there are 4 semicircles, 18/4=4.5, so the area of each semicircle is 4.5 pi. Therefore the area of a whole circle is 9 pi, so the radius of the circle is 3. That means the diameter of the circle, which is also the side of the square, is 6, so the area of the square is 36. Therefore the percent of the design that is green fabric is:
18pi/18pi+36
= 56.52/92.52
= about 0.611, which rounds to 61%.
Answer:
For instance, there's the basic formula that the area of a triangle is half the base times the height. This formula only works, of course, when you know what the height of the triangle is. ... That is to say, the area of a triangle is half the product of two sides times the sine of the included angle.
