Answer:
i dont see it
Step-by-step explanation:
.......................................................................................
Remember
(ab)/(cd)=(a/c)(b/d)
and

1kg=1000g=1*10^3g
hmm, I estimate, 4 of them
x=number of attoms
mass of 1 times x=1*10^3
3.95*10^-22 times x=1*10^3
divide both sides by 3.95*10^-22
x=

=

=

a million has 9 zeroes
so 24 zeroes is alot that is a <span>septillion, so there are 2.5316 septillion uranium atoms in 1kg
a. 4
b. underestimate

Answer:
a=25
Step-by-step explanation:
since angle T is 60, and angle Y is the exact same as T, it would make sense that a=25 [3(25)-15]
Answer:
0.4
Step-by-step explanation:
Probability = Favourable Outcomes / Total Outcomes
Probability (Blue socks drawn out) = Blue Socks pairs / Total Socks pairs
6 / ( 5 + 6 + 3 + 1 )
