The decay of 277 mg of an isotope is described by the function A(t)= 277e-0.019t, where t is time in years. Find the amount left

UNO [17]

The decay of 277 mg of an isotope is described by the function
A(t)= 277e-0.019t,
where t is time in years.
To find the amount left after 64 years,

We substitute t = 64 in the expression.
A(t=64)= 277e-0.019(64)
or A(t=64) = 277 * e-1.216
= 277 * 0.29
= 82 mg

Here are Xavier's bowling scores:

SpyIntel [72]

Answer:

151

Step-by-step explanation:

Given the following scores

132,140,130,190,112,200,185, 172,163,151,149 . What isn’t the median ?

Median can be gotten whenever we arrange a set of scores in ascending or descending order.

Arranging the above scores in the ascending order, we have

112,130,132,140,149,151,163, 172,185,190 and 200

Median = 151

Diane runs 10 miles in 55 minutes, how many minuets does she take per mile?

Brut [27]

Step-by-step explanation:

Hi!!

 It's simple, you can do it easily. 

no. of miles = 10 miles

time = 55 mins.

now,

no. of mins for 1 mile = no. of miles/ time

 = 10 /55

 =0.18181818 min.

so, she takes 0.181818 or 2/11 min per each mile.

Hope it helps...
