Answer:
Multiply the top equation by 3
Step-by-step explanation:
Answer:
The amount remaining after 24 hours is 17.5 milligrams.
Step-by-step explanation:
The rate of decay is proportional to the amount of the substance present at a time
The equation is
Rate=k*amount remaining at(time)
Where k = constant of proportionality.
So we don't know the value of k, let's find it.
7= k(70)(6)
K= 1/60
Amount remaining after 24 hours
7= 1/60 * x* (24)
(60*7)/24= x
17.5 = x
The amount remaining after 24 hours is 17.5 milligrams.
Answer:
$541
Step-by-step explanation:
Given:
The repair bill includes $355 for parts $146 for labor and a sales tax of $40
Question asked :
what is the total amount we owed = ?
Solution:
Total cost of parts to repair = $355
Total cost of labor = $146
Sales tax =$40
By adding all the cost:
Total cost of repair = $355 + $146 + $40
= $541
Therefore, total amount we have to pay = $541
