Answer:
first one is rational, second is also rational, third is rational, fourth is rational, and fifth is irrational.
Step-by-step explanation:
Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. The reason why 
is an irrational number is bc it's not a perfect square while
equals to 7 and is a perfect square.
Answer:b
Step-by-step explanation:
While this problem seems confusing, the answer is rather simple.
All you have to do is the reverse of what they are asking.
This is, substract 8 to 60 and then divide by 4:
So the interval which 13 falls into is 10 to 20 and the answer is b.
The given angles are forming alternate interior pair, so :
hence, value of x = 8°
a.
This is the geometric sequence: a1 = 1.5 m = 150
cm, r = 0.74
The formula now is an = a1 x r ^ n-1
Just substitute a1 = 150 cm and r = 0.74
an = 150 x (0.74) ^ n – 1
b.
The second part is:
A6 = 150 x 0.74 ^ 6-1
= 150 x 0.74 ^5
= 150 x 0.221906624
= 33.28509936 cm
