Answer:
Volume required = 100mL
Step-by-step explanation:
Let the volume of 30% solution required be = V mL
Amount of solute in V mL of solution = 30% of V = 0.3V...............(i)
This amount is also present in 150 mL of 20% solution
For 150 mL of 20% solution we have amount of solute = 150 mL X 20%
= 30..............(ii)
Thus equating i and ii we get
0.3V = 30
Thus V =100 mL
Answer:
12
Step-by-step explanation:

It would be about 4/10 of a gallon
Comparing the numbers, it is found that the tenths value first determines which of the numbers 6.399 or 6.400 is the larger number.
The decimal numbers are 6.399 and 6.400.
- The ones value for each is 6.
- For the first value, the tenths digit is of 3, while for the second is of 4.
The tenths digit is the <u>first in which there is a difference</u>, hence, it determines which of the numbers 6.399 or 6.400 is the larger number.

Answer:
The value of y is 12
Step-by-step explanation:
y∝x
y = kx
y = 2x
when x = 6, y = 2(6)
= 12
