As per the problem,
Rhonda bought a new laptop for $800.
The laptop depreciates, or loses, 20% of its value each year.
The value of the laptop at a later time can be found using the formula

Here we have
P=$800
r=20%=0.20
t=2 years
Substitute the values in equation (1) we get

The laptop be worth in two years will be $512.

you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight. Now you need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin. You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.
at what rate per minute should the 250 cc solution be adminstered
I have a screenshot of the answer
Answer:
x = {9, -3}
Step-by-step explanation:
- 2| x-3| - 5 = 7
- 2| x-3| = 12
- | x-3| = 6
- x - 3 = ± 6
- ⇒ x= 3+ 6= 9
- ⇒ x= 3 - 6= -3
Or it can be shown as:
