Answer:
x = 4.5
Step-by-step explanation:
a^2 + b^2= = c^2
4^2 + 2^ = c^2
16 + 4 = c^2
20 = c^2 --> find square root of 20 and round to nearest tenth*
4.47 = c
round up to 4.5
Answer:
£ 14,430
Step-by-step explanation:
Costing Price = £13,000
Increase = 11% of 13000
=> 11/100 × 13000
=> 11 × 130
=> £ 1430
Increased Price = 13,000+1430
=> £ 14,430
Rational numbers are those numbers that are integers and can be expressed in the form of x/y where both numerator and denominator are integers whereas irrational numbers are those numbers which cannot be expressed in a fraction. ... The denominator of a rational number is a natural number(a non-zero number).
Rational numbers and irrational numbers are mutually exclusive: they have no numbers in common. Furthermore, they span the entire set of real numbers; that is, if you add the set of rational numbers to the set of irrational numbers, you get the entire set of real numbers.
Answer: If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.
