Determine if 0.68 is rational or irrational and give a reason for your answer.

Answers

Answer 1
I believe it is, because the decimal is not endless
Answer 2

0.68 is a rational number because it is a finite decimal number.

0.68 is a rational number because it is a finite decimal number and all finite decimal numbers have undoubtly an equivalent rational number, that is, a real number of the form [tex]\frac{a}{b}[/tex], where [tex]a \in \mathbb{R}[/tex] and [tex]b \in \mathbb{R} - \{0\}[/tex]. In this case, 0.68 is equivalent to the rational number [tex]\frac{68}{10} = \frac{34}{5}[/tex].

In a nutshell, 0.68 is a rational number because it is a finite decimal number.

Find the measurement of one of the vertical angles .

Answers

Answer:

x = 15 degrees, one vertical angle is 165 degrees

Step-by-step explanation:

3x = x + 30

3x - x = 30

x(3-1) = 30

2x=30

x=15

All the angles need to add up to 360 degrees.

15 + 15 + 2y = 360

11+15+17+19+20+24

HELP!!! vlogger who is just starting out made three videos. So far, she has 312 subscribers, who watched one, two, or all three videos. The three videos got a combined total of 740 views. Assuming each subscriber only viewed a particular video once, how many more subscribers watched all three videos than only one video?

Answers

Answer:

116 more people

Step-by-step explanation:

Let a, b, c signify the numbers of subscribers who watched 1, 2, and 3 videos, respectively. So we can say that:

a +b +c = 312 this means that there are 312 subscribers, total

a +2b +3c = 740 this means that there were 740 total views

Next, deduct the double the first equation from the second.

(a +2b +3c) -2(a +b +c)

= (740) -2(312)

this will give us: c -a = 740 -624 = 116

Therefore, 116 more people watched all three videos than watched one video.

hope this helps

16777216

= 16,777,216

Step-by-step explanation:

-4^5 *  -4^7

we add powers in all circumstances where both powers would naturally stay inside brackets = (4^5)x( 4^7) = 4^12

(-4 x-4 x-4 x-4 x -4 )  x  (-4x-4x-4x-4x-4x-4x-4)

= -1024 x -16384 = 16777216

because

1024 x 16384 = 16777216

if one was shown as (4^5)^7 then it would be a completely differnet question and then we would multiply the powers but symetrical multiplications like -4^5 x -4^7 we add them.
