Years of decay...

It takes around 4 years for something to go through their half life (depending on the thing). This chart is showing the years go by (half lives that occur within the years) while the decaying is happening.

Haley had 56 dollars she spent 5/8 of her money on a new shirt how much money did she have left after buying the shirt
Mrac [35]

First you would multiply $56 by 5/8:

56 * 5/8 = 35

Now you know that she spent $35 on the shirt. So, subtract 35 from 56 and that's your answer.

56 - 35 = 21

Haley has $21 after buying the shirt. :)

8z-13=7 what's the number that replaces z
Goshia [24]
All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.

Write any fraction that is less than 1/8
kotegsom [21]
<span>Sample answers are 1/9, 1/10, etc.

Explanation:
To write a fraction less than 1/8, you can keep the numerator 1 and make the denominator any number greater than 8. 1/8 is the same as one part out of 8. Imagine having many pizzas the same size, but cut into different numbers of pieces. 1 piece out of 8 would be a bigger piece than 1 piece out of 9, out of 10, or anything more than 8.</span>
