Answer:
Son = 14
Father = 42
Step-by-step explanation:
Let son age be x
Father's age is 3x and x + 28
3x = x + 28
2x = 28
x = 28/2 = 14
Father's age is x + 28 = 42
Answer: B
because 6.50 for 400 and the other is 2.14 150
so 2 of b is 300g 4.24 so 3 of the is 450 for 6.46
A is 6.50 for 400g
or
B is 6.46 for 450g
Answer: 216 millilitres
Step-by-step explanation:
From the question, you are given that there are 3 milliliters of compound A used for every 5 milliliters of compound B. That means compound A and B are in ratio 3 to 5. That is,
A : B = 3 : 5
If a chemist wants to make 576 milliliters of the drug, then find the ratio of compound A.
To do that, first add the ratio of both together, 3 + 5 = 8
For compound A,
3/8 × 576
1728/8 = 216 millilitres
Therefore, 216 millilitres of compound A are needed.
