Answer:
8 new chicks can be fitted in the coop.
Step-by-step explanation:
A chicken coop holds 10 hens or 20 chicks.
That means space in the coop for 10 hens = space for 20 chicks
Or space for 1 hen = space for 2 chicks
Now
th of the hens were removed from the coop.
So, number of hens removed from the coop = ![\frac{2}{5}\times 10](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%5Ctimes%2010)
= 4 hens
And space for 4 hens in the coop = space for the 8 chicks
Therefore, 8 new chicks can be fitted in the coop.

D
Step-by-step explanation:
11.1/0.01=11.1*100=1110
Answer:
see below
Step-by-step explanation:
Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.
If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:
A' = (1/2)A = (1/2)(8, 4) = (4, 2)
1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
Answer:
The rational numbers are
and the irrational functions are
.
Step-by-step explanation:
A rational number can be expressed in the form of
, where p and q are integers and q is not equal to 0. For example
.
An irrational function can not be expressed in the form of
, where p and q are integers and q is not equal to 0. For example
.
If any number is multiplied by a irrational number then the resultant number is an irrational number.
By the above definition we can conclude that:
The number
is a rational number.
![\sqrt{48}=\sqrt{16\times 3}=4\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B48%7D%3D%5Csqrt%7B16%5Ctimes%203%7D%3D4%5Csqrt%7B3%7D)
Therefore
is an irrational number.
![6.25=\frac{625}{100}=\frac{25}{4}](https://tex.z-dn.net/?f=6.25%3D%5Cfrac%7B625%7D%7B100%7D%3D%5Cfrac%7B25%7D%7B4%7D)
Therefore 6.25 is a rational number.
![0.01045=\frac{1045}{100000}=\frac{209}{20000}](https://tex.z-dn.net/?f=0.01045%3D%5Cfrac%7B1045%7D%7B100000%7D%3D%5Cfrac%7B209%7D%7B20000%7D)
Therefore 0.01045 is a rational number.
![\sqrt{\frac{16}{81}}=\frac{4}{9}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B16%7D%7B81%7D%7D%3D%5Cfrac%7B4%7D%7B9%7D)
The number
is a rational number.
![\sqrt{\frac{3}{16}}=\frac{\sqrt{3}}{4}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B3%7D%7B16%7D%7D%3D%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B4%7D)
The number
is an irrational number.
![0.\bar{42}=\frac{42}{99}](https://tex.z-dn.net/?f=0.%5Cbar%7B42%7D%3D%5Cfrac%7B42%7D%7B99%7D)
Therefore
is an irrational number. The numbers with recursive bar are always rational numbers.
