It’s 2x the size I believe :)
D.the number of times the drug has removed a certain percentage of fluid from the patient's lungs
Step-by-step explanation:
the introduction of a fraction tells us that we are dealing with multiplications, and therefore a geometric sequence (where every new term is created by multiplying the previous term by a constant factor, the ratio r).
I think your teacher made a mistake, or you made one when typing the question in here.
there is no factor r that creates
15×r = 9
and
9×r = 5/27
it would mean that
15 × r² = 5/27
r² = 5/27 / 15 = 5/27 × 1/15 = 5/405 = 1/81
r = 1/9
but 15 × 1/9 = 5 × 1/3 = 5/3 is NOT 9
and 9 × 1/9 = 9/9 = 1 is NOT 5/27
so, this can't be right.
on the other hand
15 × r = 9
r = 9/15 = 3/5
and then
9 × 3/5 = 27/5
so, either the sequence should have been
15, 5/3, 5/27
or (and I suspect this to be true)
15, 9, 27/5
under that assumption we have
s1 = 15
r = 3/5
sn = sn-1 × r = s1 × r^(n-1) = 15 × (3/5)^(n-1)
s10 = 15 × (3/5)⁹ = 15 × 19683/1953125 =
= 3 × 19683/390625 = 59049/390625 =
= 0.15116544 ≈ 0.151
Answer:
80 degrees
Step-by-step explanation:
The only given angle here is angle 4, which measures 100 degrees.
<u>1) Identify angle relationships</u>
Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.
<u>2) Solve for angle 6</u>
180-Angle 4=Angle 6
180-100=Angle 6
80=Angle 6
Therefore, the measure of angle 6 is 80 degrees.
I hope this helps!
Answer:
25.9%
Step-by-step explanation:
Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose
let the dimension of the cylinder be
radius= 3in
height= 5 in
Step two
The expression for the total surface area of a cylinder is
T. S. A. =2πrh+2πr2
substitute
T. S. A. =2*3.142*3*5+2*3.142*3^2
T. S. A. =94.26+56.556
T. S. A. =150.816 in^2
Now let us find the error
%error= actual -expected/expected*100
%error= 190 -150.816/150.816*100
%error= 39.184/150.816*100
%error= 0.259*100
%error= 25.9%
Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above
