Which of the following numbers is rational? select all that apply. 7.6 22/7 1.01 (line is over "01") pi i think its 1.01, pi, and 22/7

The rational numbers are 7.6 and 1.01 (line is over "01").

Step-by-step explanation:

Consider the provided numbers.

A number   is said to be rational, if it is in the form   of p/q. Where p and q are integer and   denominator is not equal to 0.The decimal expansion of rational numbers may terminate or become periodic.

Irrational   number: A number is irrational if it cannot   be expressed be expressed by dividing two   integers. The decimal expansion of   Irrational numbers are neither terminate nor   periodic.

Now consider the provided numbers.

7.6 has a terminating decimal expansion so the number is rational number.

22/7=3.14285714 The decimal expansion of the number 22/7 is neither terminating nor periodic. Thus the number is an irrational number.

1.01 (line is over "01") has periodic decimal expansion. Thus the number is rational.

π=3.14285714 The decimal expansion of the number π is neither terminating nor periodic. Thus the number is an irrational number.

Thus, the rational numbers are 7.6 and 1.01 (line is over "01").

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
