Answer:
see the explanation
Step-by-step explanation:
step 1
Convert feet to inches
we know that
To convert feet to inches, multiply by 12
so
step 2
Convert inches to centimeters
we know that
To convert inches to centimeters multiply by 2.54
so
therefore
Chester should have multiplied the measurement in inches by 2.54 instead of dividing by 2.54
Let Liam's age= x
Max's age= 25
After two years Max's age= 25+2
After two years Liam's age= x+2
After two years Liam will be half of MAx's age,
So-
Liam's age after 2 years= 11.5 + 2= 13.5
Max's age after 2 years - 27
13.5 is half of 27 answer
Hope I helped~!
Answer:
Y = 1/2
Step-by-step explanation:
6/36 = y/3
Y = 1/2
Just multiply 3 by both sides
Given that the concentration of salt in a 125 ml of salt solution is 20%, this means that the ratio of salt to water in the solution is 20 : 80 = 1 : 4.
Thus, the amount of salt in the 125 ml 20% salt solution is given by 20% of 125 = 0.2 x 125 = 25ml and the amount of water in the 125ml 20% salt solution is 125 - 25 = 100 ml.
When 25 ml of water is added to the 125 ml 20% salt solution, the new amount of water is 100 + 25 =125 and the amount of salt remain 25 ml.
Thus, the new volume of the solution is 125 + 25 = 150 ml and the proprtion of salt in the new solution is given by 25 / 150 = 0.1667
Therefore, the concentration of a new solution <span>obtained by mixing 25ml of water with 125ml of a 20% salt solution in water is 16.67%</span>
Answer:
2 because you can't add the parentheses while multiplying
