452 because you will multiply 80 by 6 and get 480 and subtract 28 from that!
Answer: it will take them about 24 minutes working together
Step-by-step explanation:
1/40 + 1/60 =
6/240 + 4/240 = 10/240 = 1/24
1/24 = 1/t
Cross multiplication:
1*t = 1*24
t= 24
16 because one eighth is 2 and if u times 2 by 8 because it’s one eighth then u have 16
Anything raised to the power of 0 is 1. So standard form = 5.84
