Answer: 7 years
Step-by-step explanation:
= In2 / ∧
since the half life is given , we have :
22 = In 2/ ∧
∧ = In2/22
∧ = 0.032
Recall the formula for half life:
= 
Therefore:
0.80 = 
Take the In of both sides
In 0.80 = - 0.032t
t = In 0.80 / - 0.032
t = 7 years
Where is the diagram? How do we answer without it?
You really just need the little table they provide to figure this one out, but here we go!
<span>First, you must find what class the person falls under. For this, it would be Class 3 since it is used for business purposes, but no male under 25 has driven it. You then find the premium for 100/300 under class 3, which is $549.70 and the property damage of 25,000 (The 25 in 100/300/25 means the damage in thousands), which is $98.20 and add the two together. So the total premium would be $647.90 in total annual premium.</span>
Answer:
12
Step-by-step explanation:
12 dimes is $1.20, so your total for the quarters is $3.25. Since there are 25 coins total and 12 of them are dimes, 25 - 12 = 13, so you have 13 quarters. 13 times its value of 25 cents leaves you with $3.25, fulfilling your needed total.
There likely was an easier way to do this, but I'm unfamiliar with it so I ended up doing this.
