The land area of Florida is 170 000 square kilometres, this is because 1 700 000 divided by 10 is 170 000.
Answer:
dA/dt = k1(M-A) - k2(A)
Step-by-step explanation:
If M denote the total amount of the subject and A is the amount memorized, the amount that is left to be memorized is (M-A)
Then, we can write the sentence "the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized" as:
Rate Memorized = k1(M-A)
Where k1 is the constant of proportionality for the rate at which material is memorized.
At the same way, we can write the sentence: "the rate at which material is forgotten is proportional to the amount memorized" as:
Rate forgotten = k2(A)
Where k2 is the constant of proportionality for the rate at which material is forgotten.
Finally, the differential equation for the amount A(t) is equal to:
dA/dt = Rate Memorized - Rate Forgotten
dA/dt = k1(M-A) - k2(A)
Answer:
Step-by-step explanation:
The room is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = length × width
The rectangular hotel room is 3 meters by 5 meters. The area of the room would be
Area = 3 × 5 = 15 square meters
The owner of the hotel wants to re carpet the room with carpet that cost $15.00 per square meter. This means that the cost to re carpet the room would be
15 × 15 = $225
Total amount of money paid
=11 x 15
=$165
total amount of money sold
=25 x 15
=$375
difference
= 375 - 165
=$210
Answer:
Actual length = 36
Step-by-step explanation:
<u>0.5 inches</u> = <u>12 inches</u>
1.5 = x
0.5x = 18 Solve for x
x = 36
