No it would be $481. 80 because of the 1.5. you ar3 supposed to do 7.30 times 44 and then equals 321.20 so you times that by 1.5
Answer:
an infinite number
Step-by-step explanation:
The left side of the equation is a restatement of the right side of the equation. It is true for all values of x. There are an infinite number of solutions.
4 km/h because 10-2 because of the 2 km left which =8 then you divide that by 2 to figure out the km per hour which = 4 so 4 km/h
The general way to work this out is to solve the general expression for
the remaining quantity versus half-life, using logarithms. But that's not
necessary with these numbers.
Look at the numbers:
-- 3 mg is 1/4 of 12 mg.
-- 1/4 is the product of (1/2) x (1/2).
-- So the 3 mg is what's left of 12 mg after 2 half-lives.
The 26 minutes must be two half-lives.
-- The half-life of that substance is 26/2 = <em>13 minutes</em>.
