I have no clue but im going off a limb and say 56878
Answer:
Composite
Step-by-step explanation:
A whole number that can be divided exactly by numbers other than 1 or itself. Example: 9 can be divided exactly by 3 (as well as 1 and 9), so 9 is a composite number
Answer:
Your answer is 29.
Step-by-step explanation:
pythagorean theorem: a^2+b^2=c^2
equation: 20^2+ 21^2=x^2
next, simplify it to 400+441=x^2 and you would get 841.
now we must find the square root of 841 to get 29
The coefficient is the number that is beside the variable so that answer is 18 . The constant is the number that has no variable so that one is 36.
The amount remaining after 171 hours is 18.75 grams
<h3>How to calculate Exponential Decay?</h3>
Nuclear half-life expresses the time required for half of a sample to undergo radioactive decay. Exponential decay can be expressed mathematically like this:
A(t) = A₀(¹/₂)^(t/t_1/2)
where;
A (t) - the amount left after t years;
A₀ - the initial quantity of the substance that will undergo decay;
t_1/2 - the half-life of the decaying quantity.
We are given;
t_1/2 = 57 hours
t = 171
A₀ = 150
Thus;
A(171) = 150 * (¹/₂)^(171/57)
A(171) = 150 * 0.125
A(171) = 18.75 grams
Thus, the amount remaining after 171 hours is 18.75 grams
