Well 1A is wrong as 13+4=17 and 11+7=18 and 2B is also wrong as 6 squared is 36 and 4 squared is 16,36+16=52 6+4=10 10 squared is 100 on (6+4) squared you would do the addition as there is BIDMAS brackets indices division multiplication addition and subtraction
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.

Therefore
is an irrational number.

Therefore 6.25 is a rational number.

Therefore 0.01045 is a rational number.

The number
is a rational number.

The number
is an irrational number.

Therefore
is an irrational number. The numbers with recursive bar are always rational numbers.
180-50 would be 130.

<h3>What is data?</h3>
Data is information that has been translated into a form that is efficient for movement or processing. Relative to today's computers and transmission media, data is information converted into binary digital form. It is acceptable for data to be used as a singular subject or a plural subject.
Given:
Total students participated = 27
20 students participated in individual events
12 students took part in team events.
We have N(All students) = 27
N(individual) = 20
N(Team)= 12
So,

=20+12-27
=32-27
=5
Hence, 5 students took part in both individual and team events.

Answer:
65000
Step-by-step explanation:
(rounding to nearest thousands)
2014- 13000 sold
2015- 13000 more than 2014, so 26000
2016- same as 2016, 26000
just add them up-
13000+26000+26000= 65000
