Your answer is

because the numbers raised to negative powers must be flipped over the divisor to become positive. Then, when multiplying 2 and z, you add their exponents.
First off, mass is not measured in pounds, weight is.
But, I can still solve this for you!
1/14 * 3/4
3/56 pounds is your answer
Hope this helps!
28x+-21 you simplify them first
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,

So, the required fraction is approximately
.
Answer:
Always.
Step-by-step explanation:
That is the reason why when you are trying to calculate the area of a triangle you do the base x height divided by two or in half. If you printed out the triangle twice then cut it out and put the two together it would be a rectangle.
