Loss % = loss/C.P.*100
= 60/300*100
= 60/3
= 20% loss
Let x represent the percent of increase in the tree's height and let n represent the number of years.
x= n (36/4343)
Hope this helps!
Answer:
150
Step-by-step explanation:
100% represents 500 jars
Subtract the sum of the percentage of other jars for percent of blue jars
100 - (30 + 25 + 15) = 100 - 70 = 30%
That is 30% of the jars are blue
Calculate 30% of 500 to obtain number of blue jars
30% =
= 0.3, hence
number of blue jars = 0. 3 × 500 = 150
Step-by-step explanation:
-3 (4a-5b)
=-3×4a -(-3×5b)
=-12a+15b
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.
