Why is blood type ab considered the universal receiver?

1 answer:

5 0

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.

2b^2+4b–2=0 what is the answer?

s2008m [1.1K]

$2b^2+4b-2=0\\
2(b^2+2b-1)=0\\
2(b^2+2b+1-2)=0\\
2((b+1)^2-2)=0\\
2(b+1)^2-4=0\\\
2(b+1)^2=4\\\
(b+1)^2=2\\
b+1=-\sqrt2 \vee b+1=\sqrt2\\
b=-1-\sqrt2 \vee b=-1+\sqrt2

How can you use addition and subtraction to put together and separate measures of an angle and its parts?

Oksanka [162]

We can use addition and subtraction to put together and separate measures of an angle and its parts by looking for the complementary or the supplementary angles.

For example, What is the other angle in a complementary angle in which one of the angles is 45 degrees. This is how should be answered. Ccomplementary angles are two angles that forms a total of 90 degrees.
90 = A + B
90 = 45 + B
B = 90 - 45
B = 45

The Naturally Made Bath and Body store pays $550 a month for rent and utilities. The average cost for its products to be manufac

Llana [10]

Answer:

Break-even point is at quantity 220.

Step-by-step explanation:

Given the rent amount that is fixed cost for the store = $550

The average cost of the goods = $3

The average price of the goods = $5.50

Let the total number of break-even items = Q

Thus, total revenue = 5.50 x Q = 5.50Q

At break-even, TR = TC

5.50Q = FC + VC

5.50Q = 550 + 3Q

5.50Q - 3Q = 550

2.50Q = 550

Q = 550 / 2.50

Q = 220

Thus break-even point is at quantity 220.
