As far as I know 0 IS a rational number. The only ones that are not rational are negative numbers. :) Though I could be wrong.....
Answer:
Step-by-step explanation:
The 2 in 2.6 is in the ones place so we know that it equals 200. The 6 in 2.6 is in the tenths place so we know that it equals 60. Add 200 with 60 to get 260/10. The denominator is 10 because 2.6 only extends to the tenths place.
Answer:
x= 42.5°
The angle shown in the figure is a right angle.
x+3x+10=180°
=>4x= 170°
=>x= 170/4= 42.5°
I truly don’t know the answer but i think it is 837 feet
Answer:

Step-by-step explanation:
First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.
Plug in the information we have to get the equation for this sequence:

Then, you can solve for the 15th term:

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.
