Answer:
12 and 36
Step-by-step explanation:
Call the age of both Bill and his father is a and b, respectively
we have:
b=3a
b-3=4(a-3) ->b=4a-12 -> 3a=4a-12 ->a =12 -> b=36
(0.300 kW) * (24 h/day) * (30 day) * ($0.07/kWh) = $15.12
AB/DE = BC/EF
CA/FD = AB/DE
MJ/QN = JK/QP
LM/PQ = MJ/OP
Answer:
150 mins or 2 hrs 30 mins
Step-by-step explanation:
This is simply the LCM ( lowest common multiple)
therefore, you find all the prime factors of 25 using a tree diagram resulting in 5^2 and 30 which will be 2 x 3 x 5. Then you multiply all the factors together and you will get 5 x 5 x 2 x 3 = 150
so....
the answer is after 150 mins
or 2 hours and 30 minutes
I think it’s option 4. The bottom right one. Hope that’s right!
