Answer:
the answer is 128.4
Step-by-step explanation:
To round up a number to the nearest tenth if the hundredth is more than or 5 you add 1 to the tenth but if it less than 5 you remove the other numbers and leave the number like that which will give you 128.4.
How would be so that. Where is the graph
Porsha` s expression:
5,000 ( 1 + 0.0375 ) ^24
A = P * ( 1 + i ) ^n
n = 6 * 4 = 24
i = 0.0375 : 4 = 0.009375
Porsha`s expression is wrong. True expression is:
5,000 * ( 1 + 0.009375 ) ^24
Answer: B ) Porsha`s expression should have 1 + 0.009375 in the parentheses.
3(y+10) = 3(3). For additional simplification, the answer may be written as
y+10 = 3
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.
