Get rid of negative exponents by remembering that x^-a= 1/x^a.
6^-3= 1/6^3
Evaluate the exponent
6^3= 216
Final answer: 1/216
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial mass is m = 80 g.
- Half life = 10 days
- Total time = 60 days
<u>Number of half-life periods:</u>
<u>Equation for remaining sample:</u>
- s = m*(1/2)^r
- s = 80*(1/2)^6 = 80/64 = 1.25 g
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
I’m pretty sure the gcf is 44
