Answer:
<h2>А. 3, 5, 7</h2><h2 />
Step-by-step explanation:
Because
7 - 3 = 4
7 + 3 = 10
then
7 - 3 < 5 < 7 + 3
the 3 other cases don’t fit with this rule.
Answer:
14.99 hours
Step-by-step explanation:
The formula for half-life is given as,
R/R' = 2ᵃ/ᵇ...................... Equation 1
Where R= Original mass of sodium-24, R' = mass of Sodium-24 after disintegration, a = Total time taken for sodium-24 to disintegrate, b = half-life of sodiun-24.
Given: R = 1 kg, R' = 0.0156 kg, a = 90 hours
Substitute into equation 1 and solve for b
1/(0.0156) = 2⁹⁰/ᵇ
Taking the log of both side
log[1/(0.0156)] = log(2⁹⁰/ᵇ)
log[1/(0.0156)] = 90/b(log2)
90/b = log[1/(0.0156)]/log2
90/b = 6.0023
b = 90/6.0023
b = 14.99 hours
b = 14.99 hours.
Hence the half-life of Sodium-24 is 14.99 hours
Answer:

Step-by-step explanation:
$1250 divided by 10 months to figure out how much he payed each month.
Answer:
A = Heterozygous
B = Capital
C = Capital
G = Heterozygous
Step-by-step explanation:
Depends on which is dominant (Captital Letter)
If both are the same (lowercase or uppercase) eg TT, or tt They are capital
If different casings, they are Heterozygous.
(DUE TO Brainly disliking the word please refer Capital as H,o,m,o,z,y,g,o,u,s
