I divide it the number to get the same denominator and do it on the top too.
Really dude I don't even no that but maybe someone else
Marcia dissolved 1 kg of salt in 3 litres of water
Bobby dissolved 2 pounds of salt in 7 pints of water
We know that
1 litre = 2.11 pints
We also know that
1 pound = 0.4535 kg
Now if we take the case of Bobby, and convert the pound to
kg then
1 pound = 0.4535 kg
2 pounds = (0.4535 * 2) kg
<span> =
0.907 kg</span>
<span>
= 0.91
kg</span>
Bobby dissolved the salt in 7 pints of water
We know
2.11 pints = 1 litre
Then
7 pints = (7/2.11) litre
<span> = 3.32
litres</span>
So we now see that Bobby has dissolved 0.91 kg of salt in
3.32 litres of water
Marcia dissolved 1 kg of salt in 3 litres of water.
So Marcia has made a more concentrated solution since she
has dissolved more salt in less amount of water whereas Bobby has dissolved
less amount of salt in more water.
The answer is B 36 because the chance of you grabbing a white or black is 12/15 meaning if you pulled 15 marbles, most likely 12 of them are white or black. so, because 15 goes into 45 3 times, you multiply 12/15 by 3 getting 36/ 45 meaning you will mostly pull 26 black or white marbles.
A) No, the root 3 has multiplicity of 3.
B) No, there are two imaginary solutions.
C) No, the root −2 has multiplicity of 3.
D) Yes, the Fundamental Theorem of Algebra does not apply to this equation.
