Answer : The time taken by the element to decay to 2 grams is, 75.2 minutes
Step-by-step explanation:
Half-life = 13 min
First we have to calculate the rate constant, we use the formula :
Now we have to calculate the time passed.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant = 
t = time passed by the sample = ?
a = initial amount of the reactant = 110 g
a - x = amount left after decay process = 2 g
Now put all the given values in above equation, we get
Therefore, the time taken by the element to decay to 2 grams is, 75.2 minutes
Answer:the average this year is $13284
Step-by-step explanation:
Engineering students at riverside college last year received, on. Average, $11,070 in scholarships and grant money. This year, the average is 20% higher. The value of the increase would be
20/100 × 11070 = 0.2 × 11070 = $2214
Therefore, the average this year would be the sum of the average last year and the value of the increase. It becomes
11070 + 2214 = $13284

There are two solutions. If you factor a -p out of the equation, you can easily see this. (-p)(p + 11) = 0. The values of p that make this true are 0 and -11.
{0, -11}
