Answer:
<em>24.66 mg</em><em> of medicine will be left.</em>
Step-by-step explanation:
The given exponential equation is,

Where,
A(t) = amount after time t
i = initial amount = 100 mg
r = rate of change = -14% = -0.14 (-ve is taken because the amount is decreasing)
t = time = 10 hours
Putting the values,



Answer:
A. 2y^4 over x^2
Step-by-step explanation:
4x^4y^6 ÷ 7x^8y^2
First, you will find the GCF of the equation which is: 7x^4y^2 .
Then, you will divide both of the equation by the GCF which will become:
14x^4y^6 ÷ 7x^4y^2 = 2y^4
7x^8y^2 ÷ 7x^4y^2 = x^2
Hence, the final answer is 2y^4 over x^2
Answer:

Step-by-step explanation:
The volume V of the fountain is equal to:
V = L*W*h
Where L is the lenght of the fountain, W is the width of the fountain and h is the high of the fountain
We already know that h is equal to x. On the other hand, if we cut a square with side of length x, L and W are calculated as:
L = 18 - 2x
W = 12 - 2x
So, replacing L, W and h on the equation of the volume, we get:
V = (18-2x)*(12-2x)*x
Finally, simplifying the function we get:


Answer:
$26.91
Step-by-step explanation:
11.96 divided 4 = 2.99
2.99 x 9 = $26.91
Answer:
In a survey of 2,300 people who owned a certain type of car, 1,610 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
1610/2300x100=
70%
Step-by-step explanation:
total number of people for the survey= 2300
those that wanted to buy the car= 1610
percentage= 1610/2300x 100=0.7x 100
percentage= 70%
