The area would be 9 because the perimeter of the regular quadrilateral would be 3 and if you multiply 3 by 3 you have 9.
Answer: 6
Step-by-step explanation:
A'B' = AB, and B'C' = BC. So A = (1/2)(3)(4)=6.
Answer:
So after the second tablet there is 360-mg of drug in the body.
So after the third tablet there is 372-mg of drug in the body.
Step-by-step explanation:
We know that a doctor prescribes a 300-mg antibiotic tablet to be taken every eight hours. Just before each tablet is taken, 20% of the drug remains in the body.
We know that 20%=0.2.
We conclude that after the first pill, 300mg of the drug is in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the second tablet:

So after the second tablet there is 360-mg of drug in the body.
We have the following formula, to calculate how much mg of the drug is in the body after the third tablet:

So after the third tablet there is 372-mg of drug in the body.
Step-by-step explanation:
earbuds
we have a 1in : 0.2in scale of drawing to reality.
0.2 = 2/10 = 1/5
so, 1in in the drawing is actually 1/5in in reality.
how long are the 4in in the drawing ?
well, 4 times the 1in thing.
4×1/5 = 4/5 = 0.8in long
again the similar triangles
similar triangles means that each pair of corresponding lines (sides, heights, ...) in the triangles follows the same scaling factor for the length.
so, what do I need to multiply the side of the large triangle with to get the corresponding side length of the small triangle ?
27 × x = 9
x = 9/27 = 1/3
and that is the scale factor.
