Crank3 years ago

4 0

Step-by-step explanation:

Given that,

The mass of a patient = 70 kg

A 70kg patient has approximately 8 pints of blood.

The patient donates 470mL of blood.

We know that,

1 pint = 568 mL

8 pints = 4544 mL

Required fraction,

$\dfrac{470}{4544}=0.1\\\\=\dfrac{1}{10}$

So, the required fraction is approximately $\dfrac{1}{10}$ .

Please solve with explanation (high points)

IgorLugansk [536]

So, we know that:

$A=\dfrac{1}{2}ab\\P=a+b+c\\a^2+b^2=c^2$

We also know that $(a+b)^2=a^2+2ab+b^2$ . We will use that fact to find $c$ in terms of $A$ and $P$ .

$A=\dfrac{1}{2}ab\Rightarrow 2ab=4A\\P=a+b+c\Rightarrow a+b=P-c$

Therefore:

$(P-c)^2=c^2+4A\\P^2-2cP+c^2=c^2+4a\\2cP=P^2-4A\\c=\dfrac{P^2-4A}{2P}$

Two factors of -48 have a difference of 19. The factor with a

sdas [7]

Answer:

13

Step-by-step explanation:

Given number = -48

Listing out the possible factors of -48 in pairs along with their difference:

Factors ( $F_1\times F_2$ ) Difference ( $F1-F2$ ) Difference ( $F_2-F_1$ )

$-2\times 24$ -26 26

$2\times -24$ 26 -26

$-3\times 16$ -19 19

$3\times -16$ 19 -19

$-4\times 12$ -16 16

$4\times -12$ 16 -16

$6\times -8$ -14 14

$12\times -4$ 14 -14

On listing out the factors we find out that two of the pairs have difference = 19

The pairs are $-3, 16$ and $3,-16$

It is given that the factor with greater absolute value is positive. This means 16 would be positive while 3 would be negative.

So, our factors are $-3, 16$

The sum of the factors is = $-3+16=13$ (Answer)
