Answer:
$4.5
Step-by-step explanation:
Hot dogs=h
Cheese burgers=c
2h+3c=20
2h+5c=29
There are two ways to solve-
1. Elimination- multiply the bottom by -1.
2h+3c=20
-2h-5c=-29
-2c=-9
c=4.5
2. Just move 2h, and you get 2c=9, 4.5
Answer: half life = 1.98 seconds
Step-by-step explanation:
Given that the amount of sodium-24 in the patient’s body in milligrams after t hours is given by
S(t) = 5e–0.35t.
From the equation above, decay constant K = 0.35
Half life = ln2/K
Half life = ln2/ 0.35
Half life = 1.98 seconds
6.125
=6.000+0.125
=6+125/1000
=6+1/8
