Answer:

563 - (563x0.25) = 422.25 -> 422

422 -(422x0.25) = 316.5 -> 317

317 - (317x0.25) = 237.75 -> 238

238 - (238x0.25) = 178.5 -> 179

28 (continue the step by step process)

134.25 -> 134

100.5 -> 101

75.75 -> 76

42.75 -> 43

32.25 -> 32

Step-by-step explanation:

the time interval has to keep skipping by four hours because the medicine is filtered in that amount of time.

The multiplying by 0.25 part must be done first in order to show how much the kidney has filtered.

after this, you need to subtract that from how many milligrams of medicine are left in your system

note that if you do not subtract, you will only be showing how much the kidney has filtered. the question asks for how much is left in the SYSTEM overall, so subtracting is quite necessary to completely answer the question.

I hope this helped.

Advocard [28]

Answer:

The diameter of the ride is 44 feets.

Step-by-step explanation:

We have,

The circumference of the frame is about 138 ft.

It is required to find the diameter of the ride.

The circumference of means that the outer covering of the circle. It is given by the formula as follows:

$C=2\pi r$

r is radius

Since, 2r = d, diameter of circle

$C=d\pi \\\\d=\dfrac{C}{\pi}\\\\d=\dfrac{138}{3.14}\\\\d=43.94\ ft$

d = 44 feets

So, the diameter of the ride is 44 feets.

Answer:

56%

Step-by-step explanation:

To find a percentage, you need to take a ration of the value you want and the total. In this case, 28 is the value and 50 is the total, right? Then, to make it a s

proper percentage, you multiply by 100. As such:

$\frac{28}{50} \times 100 = \frac{14}{25} \times 100 = \\ = 14 \times 4 = 56$
