drug has a half-life of 4 hours. Assuming someone takes a dose of 512 mg, how much of the drug remains in the system after 36 hours?
0 1 mg
© 0.0000001 mg
O 0.5 mg
0 168 mg
Answer:
36 / 4 = 9 half-lives
2^9 = 512
Therefore after 36 hrs 512 / 512 = 1 mg remains

2. Roberto has a wealthy uncle who gives him two options to save money in a bank
account to save for a PlayStation 4, which will cost $518.
Option 1: Roberto's uncle deposits $100 in the first month and $50 for each additional month.
Option 2: Roberto's uncle deposits $5 for the first month and will double the about in the
account each month.
Which option above can be written as a geometric sequence?
A. Option 1
B. Option 2
C. Both Option 1 and 2
D. Neither Option 1 or 2
Answer:
B. Option 2 (only)
Step-by-step explanation:
A geometric sequence is a sequence of terms that have a common ratio.
Option 1The deposits are ...
100, 50, 50, 50, ...
The ratios of terms of this sequence are ...
1/2, 1, 1, 1
So, the ratio is not constant, and the sequence is not geometric.
__
Option 2The deposits are ...
5, 10, 20, 40, ...
The ratios of terms of this sequence are ...
10/5 = 2, 20/10 = 2, 40/20 = 2, ...
The ratio is constant, so the sequence of deposits for Option 2 is geometric.

Your car is worth $20,000 but it depreciates at a rate of
12% each year.
Write an equation showing how much your car is worth
each year.
A)f(x) = 20,000 - 12x
B)f(x) = 20,000 - 1.12*
C)f(x) = 20,000 -12%
D)f(x) = 20,000 - 0.88%
Answer:
D
Step-by-step explanation:
since the car value is decreasing by 12% each year, just take the original amount and multiply by 88% to get the value of the car for the next year, so on and so forth

At a NASCAR racetrack, the distance per lap is 2 miles. Lou Lambert drives his car at a constant rate of 160 miles per hour. Ralph Redding drives his car at a constant rate of 170 miles per hour. How long will it take before Ralph gains 2 laps in relation to Lou?
Answer:
24 minutes
Step-by-step explanation:
Given:
Distance per lap = 2 miles
Speed of Lou Lambert = 160 miles/hr
Speed of Ralph Redding = 170 miles/hr
Speed difference between the two = 170 - 160 = 10 miles/hr
Therefore, we can say that Ralph gains 10 miles in 60 minutes over Lou.
We have to find the time in which Ralph will gain 2 laps i.e. 2 [tex]\times[/tex] 2 = 4 miles.
Let us use unitary method to find the required time.
10 miles are gained by Ralph in 60 minutes
1 mile will be gained in [tex]\frac{60}{10} = 6\ minutes[/tex]
4 miles will be gained in 6 [tex]\times[/tex] 4 = 24 minutes
let please help me please
Answer:
p = 170
Setting up the formula:
The mean is the sum of the digits divided by the total digits in the set.
[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = \text{Mean}[/tex]
[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = 39[/tex] [Mean = 39]
[tex]\rightarrow \dfrac{25 + p}{\text{Total digits}} = 39[/tex] [Sum of digits = 25 + p]
[tex]\rightarrow \dfrac{25 + p}{5} = 39[/tex] [Total digits = 5]
Step-by step calculations:
Use cross multiplication:
[tex]\rightarrow 25 + p= 39 \times 5[/tex]
Simplify the RHS:
[tex]\rightarrow 25 + p= 39 \times 5[/tex]
[tex]\rightarrow 25 + p= 195[/tex]
Subtract 25 both sides:
[tex]\rightarrow p = 195 - 25[/tex]
[tex]\rightarrow p = 170[/tex]

The dimensions of this figure are changed so that the new surface area is exactly 1/3 what it was originally. What is the new surface area? Enter your answer as a decimal in the box. ft² Please help! tysm ♥
The new surface area is 198.79 ft².
What is Surface Area?An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.
As per the given diagram:
All the dimensions are mentioned
new surface area is exactly (1/3) of original surface area.
Original surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) + (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)
Original surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89
original surface area = 596.38 ft²
Therefore,
New surface area = (1/3) of original surface area
= (1/3) × 596.38
= 198.79 ft²
Hence, the new surface area is 198.79 ft².
