Answer:
Now, the father is 60, and the son is 24.
Step-by-step explanation:
Now:
Father's age = f
Son's age = s
4 years ago:
Father's age = f - 4
Son's age = s - 4
In 12 years:
Father's age = f + 12
Son's age = s + 12
Now:
f = 3(s - 4)
In 12 years:
f + 12 = 2(s + 12)
We have 2 equations that we can solve in a system of equations.
f = 3(s - 4)
f + 12 = 2(s + 12)
f = 3s - 12
f + 12 = 2s + 24
f = 3s - 12
f = 2s + 12
Since above both equations are in terms of f, set the right sides equal and solve for s.
3s - 12 = 2s + 12
s = 24
f = 3(s - 4)
f = 3(24 - 4)
f = 3(20)
f = 60
Now, the father is 60, and the son is 24.
Answer:
30 gallons
Step-by-step explanation:
step 1 right it out
2 hour is 120 mins and 4 cups are poured per min
step 2 Equation time
so your equation should be
4/1=x/120
step 3 solve it out
1 times 120 is 120 is 4 times 120 is 480
but that is not the answer 480 is the amount of CUPS that are used for 2 hrs
so all u have to do is now convert
step 4 convert
16 cups are in 1 gal. so divide 480 by 16 and get 30 gal
x=30 gallons

With replacement, each draw has a probability of
9 pink out of 18 total number of chips.
Therefore, by the multiplication rule, the probability of having both draws picking a pink is
P(pink,pink) = (9/18)*(9/18) = 81/324 [ = 1/4 ]
or
P(pink,pink) =
5,200 you round it to 5,200
