Answer:
84
Step-by-step explanation:
they are all equal sides so what you'd do is 28+28+28= 84
That ratio will be 5/100 because it's 5 out of 100 people
Therefore the probability is <= 5%
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
To get an equivalent fraction, multiply the fraction by a whole number. For example, you can do 2/3 times 2 to both sides which is 4/6.
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
