Hey! You just have to square root the 2 and 5 then multiply by 11 so the answer I came up with is 34.78505426185218
I hope I helped!
Answer:
A: Yes: triangle DBC is a dilated figure of DEF so their sides would be congruent is scaled to equality. Similar implies that the two triangles could be equal if you use transformations (translation, reflection, etc) and a dilation is a form of translation
B: BC; each of the sides are scaled and looking at the two triangles it is a) easy to physically determine that they are the same and b) their placements within the triangle indicate their alignment
C: C; Once again physicality and placement indicate the alignment of the two and both of them are 90 degrees

Answer:
The expression that represents the number of days until only 10% remains is T((d) 10 %) =100×
.
Step-by-step explanation:
The equation for half life is of the form
A = A₀×
.........................................................................(1)
Where
A = Final amount
A₀ = Initial amount
t = Time
h = Half life
For the equation T(d) = 100×2⁽⁻²⁾....................................(2)
We have by comparison with the equation for half life
2 ≡
and and the equation (2) can be written as
Percentage remaining after 2 half lives is
×100=100×
However if the half life of Technetium-99m is 6 hours then we have for one day
×100=100×
Therefore an expression that represents the number of days until only 10% remains is
×100=100×
= 10 %
=
= ㏑
= ㏑(
)
=
×㏑
= ㏑(
)
=
= 3.322
Therefore the expression for the number of days 10 % of Technetium-99m will be remaining is
T((d) 10 %) =100×
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
