Answer:
870,000
Step-by-step explanation:
When multiplying the two you add as many 0's to 87 as there are in 10,000
The choices you provided do not match the question!!!
Tickets ($25): x
T-shirts ($12): y
25x + 12y + 4 ≤ 130
Since she bought 3 tickets: 25(3) + 12y + 4 ≤ 130
75 + 12y + 4 ≤ 130
79 + 12y ≤ 130
12y ≤ 51
y ≤
y ≤ 4
Since you cant buy of a T-shirt, the maximum number of T-shirts she can purchase is 4.
the half-life of the drug is 4.3 hours.
<h3>
How to get the half-life?</h3>
The half-life is the time in which an initial dose reduces to its half.
Here, we know that the drug decays by 15% each hour, so the amount of drug in the body as a function of time is:
D(t) = A*(1 - 0.15)^t
Where t is the time in hours, and A is the initial dose.
The half-life will be the value of t such that:
(1 - 0.15)^t = 0.5
Now we can solve that equation for t:
0.85^t = 0.5
ln(0.85^t) = ln(0.5)
t*ln(0.85) = ln(0.5)
t = ln(0.5)/ln(0.85) = 4.3
So the half-life of the drug is 4.3 hours.

So when you divide fractions, you keep the first fraction (in this case 5/8) then change the sign from divide to multiply, then flip the second fraction (we’ll use 1/16 first)
So 5/8 times 16/1. 80/8. Simply to 10.
Now do the same with 5/8 and 1/32
5/8 times 32/1. 160/8. Simplify to 20.
So I good prediction would be 1/32 since you have to flip the divisor and multiply.
