When a certain over the counter drug enters the bloodstream, it gradually dilutes, decreasing exponentially. You take a 200 mg d

ose at 8:00PM, and by 11:00PM, there is only 75 mg remaining.
If the drug is only effective with at least 65 mg in the blood stream, about what time should you take another dose?
Assume you don’t take another dose after 8:00PM, how much would be left in your blood stream after 10 days?

75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.

The area of a triangle is 1,4440 cm^2. The base of the triangle is 5 times the height. What is the height of the triangle?
DochEvi [55]

Answer:

h = 24 cm

Step-by-step explanation:

The formula for area of a triangle is

A = (1/2)bh     where b is the base and h is the height.

We are told that the base is 5 times the height, this translates to

b = 5h, so we can rewrite our formula to

A = (1/2)(5h)(h)  or

A = (1/2)5h²

We are given A = 1,440, so plug that in and solve for h...

1,440 = (1/2)5h²

    2,880 = 5h²    (multiply both sides by 2 to get rid of the fraction)

      576 = h²    (divide both sides by 5 to get the h value by itself)

         24 = h     (take the square root of both sides)

What is the solution to 2(-4x+1)=2/3(x+2)
Rzqust [24]

Hello!

The answer to your problem is: x=1/13

<u>Simplify both sides of the equation</u>

(2)(-4x)+(2)(1)=(2/3)(x)+(2/3)(2) (Distribute)

-8x+2=2/3x+4/3

<u>Subtract 2/3x from both sides</u>

-8x+2-2/3x=2/3+4/3-2/3x

-26x+2=4/3

<u>Subtract 2 from both sides</u>

-26/3x+2-2=4/3-2

-26/3=-2/3

<u>Multiply both sides by 3/(-26)</u>

(3/26)*(-26/3x)=(3/-26)*(-2/3)

<u>Get your answer</u>

x=1/13

Hope This Helps!
