Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
Answer:
I was wondering if you could give me brainliest because I am almost to level ace! It would mean alot!
Step-by-step explanation:
Have a good day! :)
Therefore the answer is the first one
Math:
Step #1: Distribute
<span><span>(1.8)(1.5x)+<span>(1.8)(−2.6y)</span></span>+(−2.5)(2x)</span>+<span>(−2.5)<span>(1.5y<span>)
</span></span></span>
you'd get: <span><span><span><span>2.7x+ −4.68y </span>+ </span>−5x </span>+ </span>−<span>3.75<span>y
Step #2: Combine like terms
</span></span><span>(<span>2.7x + <span>−5x</span></span>)</span>+<span>(<span><span>−4.68y </span>+ <span>−3.75y</span></span><span>)
</span></span><span>
</span><span>Your answer:
</span><span>−<span>2.3x</span></span>−<span>8.43<span>y</span></span>
Answer:
Total sales = $3600
Commission earned on $3600 = $576
Commission rate can be calculated as =
= 16%
Hence, the commission rate is 16%
