multiples of 6 = 6, 12, 18, 24 , 30, 36 ,42 , 48
multiples of 8 = 8, 16, 24,32,40,48
24 & 48 are the common multiples
so there is a 2 out of 48 chance which is 2/48 which reduces to 1/24 probability
I think it’s 7x+14 / x I’m not sure though
Answer:
You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.
Step-by-step explanation:
Let 'x' be the amount of 60% alcohol solution and y the amount of pure alcohol.
Therefore:
(0.6x + y)/320 = 0.65 ⇒ 0.6x + y = 208
x + y = 320
Solving the sistem of equations:
x = 280 and y = 40
Therefore, You will need
280 mL of the 60% solution
and 40 mL of pure alcohol.
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
