Answer:
2 grams
Step-by-step explanation:
50 years is 5 half lives as 1 half life is 10 years.
64 divide 2 = 32-1 half life
32 divide 2 =16-2nd half life
16 divide 2 = 8-3rd half life
8 divide 2 = 4-4th half life
4 divide 2 = 2-5th half life
This means we will have 2 grams left of the radioactive substance after 50 years.
Answer:
8
Step-by-step explanation:
1) let’s take the original number as “x”
So
3x=28-0.5x
Lol don’t worry I’ll show you how I got that
So it says 3 times a number. That tells me my number, X is multiplied by 3 so I have
3x so far
Next it says “is equal to”, this tells me my number 3x is equal to something so I have this now:
3x=
After that it says “half of a number” so I know I will have 0.5x subtracted from 28. Since it says subtracted from 28 that means my number will be subtracted from 28, not the other way around so
3x=28-0.5X
Now I can solve this by bringing “-0.5” to the left.
3x+0.5x=28
3.5x=28
Divide both sides by 3.5 and
X=8
There are a few ways to find out the correct answer. One of them is to divide 2.40 by 6 to get a price of one cake and then multiply it by 10:
2.40 ÷ 6 = 0.40
0.40 * 10 = 4.00
Answer: Ten cakes would cost 4 pounds.
