Multiply 145.80 by 2/3, get $97.20 in two days.
I think the correct answer will be SAS OR ASA
Answer:
61.5
Step-by-step explanation:
PEMDAS
Parentheses
Exponents
Multiplication and Division
Addition and Subtraction
There is a Parentheses so we do it first:
6.5 times 4 is 26
We don't have any exponents so it is multiplication next since we don't have any division
26 times 2.25
58.5+5-2
We go from left to right
58.5+5 is 63.5
63.5-2 is 61.5
Thus the answer is 61.5
Hope this helps!
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×
