Answer:
t = 22
2t = 45
Step-by-step explanation:
3t = 68
t = 68/3
Let's start with 17 seats and just bikes. That is 34 wheeles. Now, each bike we replace with a go-kart will add 2(because we take away 2 and add 4). We need to add 14 wheels. This means we will replace 7 bikes with go-karts. 7 go-karts (28 wheels) and 10 bikes (20 wheels) is the answer.
The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!
Multiply both sides by 10 : 20x + 6x = 50 - x
Collect the like terms: 20x + 6x = 50 - x
Move Variable to Left: 26x + x = 50
Collect like terms: 27x = 50
Divide both sides by 27: 50/27
Hope this helped :))
The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.
