What is 48,100,000,000,000 in scientific notation?
vfiekz [6]
Scientific notation is
x*10^b where 1≤x<10 and b is an integer

b is how many spaces you had to move the decimal to the left in the original number to obtain x

so
48,100,000,000,000
to
4.8100000000000
the decimal was moved 13 spaces
so b=13
a=4.81


in scientific notation, 48,100,000,000,000 is 4.81*10^{13}

A typical sugar cube has an edge length of 1.00 cm. Imagine you have a cubical box that contains a mole of sugar cubes, perfectl
alisha [4.7K]

Answer:

844368.7 m

Step-by-step explanation:

We are given that a typical sugar cube has an edge length of 1.00 cm.

We have to find the edge length of the box in meters.

Edge length of sugar cube=1 cm =10^{-2}m (1 cm=\frac{1}{100}m)

Volume of a sugar cube=side\times side\time side=(10^{-2})^3=10^{-6}m^3

1 mole of sugar=6.02\times 10^{23}units

Volume of 1 unit=10^{-6} m^3

Volume of 6.02\times 10^{23} units=6.02\times10^{23}\times 10^{-6}=6.02\times 10^{17} m^3

Volume of box=1 mole of sugar=6.02\times 10^{17} m^3

Edge length of box=\sqrt[3]{6.02\times 10^{17}}=844368.7 m

23. The letters of the alphabet are written on
Alla [95]

Answer:

21/676

Step-by-step explanation:

The total number of letters of the alphabet will be the total outcome which is 26 alphabets.

If consonant numbers are drawn out, the probability of drawing a consonant will be total consonants/total alphabets

Total consonants in the alphabet is 21.

Probability of drawing consonants = 21/26.

Since all the consonants are replaced before drawing a Z, our total outcome will not change i.e it will still be 26.

Probability of drawing a letter Z will be 1/26.

Therefore, the probability of drawing a consonant,replacing it, and then drawing a Z will be;

21/26×1/26

= 21/676
