4x = 2/5 is the same equation
Multiply 1/4 on both sides to clear the 4.
x = (2/5)(1/4) =2/20= 1/10
CHECK
(1/10)* 4= 4/10 = 2/5
Answer: 51.2 mg
Step-by-step explanation:
The exponential equation to represent decay:-
, where A is the initial value , r is the rate of decay and t is the time period.
As per given, we have
A= 400 and r= 29%=0.29
Put theses values in the above formula.
The amount left after t hours:
Put t=6 , we get
Hence, the amount of aspirin is left in her system after 6 hours= 51.2 mg
Answer:
The answer for part A: If the city is hotter in temperature more people will want the cold refreshing lemonade.
Part B: The line of best fit is a line that will have the same amount of point on each side so you should draw a straight line and then make sure it has the same amount of point on each side. To calculate the slope use Y2-Y1/X2-X1, Y-intercept is the point that intercepts the Y-intercept.
Step-by-step explanation:
Part A: Because if it is hot outside you will sweat more being less hydrated which is why more people would want a drink especially lemonade.
