I think it would be 23 bags without any cookies left over
I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
Answer:
7
Step-by-step explanation:
by similarity of traingles Δxuw and Δxyz
xu/xy = uw/yz
given xu+uy=xy and xu=uy
2(xu)=xy
xy=2(uy)
=>5x+4=2(4x-1)
=>5x+4=8x-2
=>3x=6
=>x=2
=>given length of uw=>4x-1=4(2)-1=7
Answer:
Therefore 53.05 mg will remain of the given radioactive substance after 35 hours.
Step-by-step explanation:
Radioactive Decay:
Integrating both sides
[ ]
When t=0, = initial amount
Therefore the decay equation is
Given that, = Initial amount of the radioactive substance= 140 mg
After 25 hours, 70 mg of substance remains.
N= 70 mg, t=25 hours
[ ]
The decay equation becomes
Now putting t= 35
= 53.05 mg
Therefore 53.05 mg will remain of the given radioactive substance after 35 hours.
