To find the unit rate, 391/17 gives us 23$ per hour time 13 hours is 299$ total.
Answer:
11.2
Step-by-step explanation:
the first thing you wanna do it's to change 40% into a real number to do that you move the decimal 2 places to TV he left and make it 0.40 then you multiply 0.40 with 8 and you get 3.2 so you add 3.2 to 8 and the answer is 11.2
The answer is 56! How you do this, is you take 80, and you multiply it by 7. Then you divide that answer by 10. Then you have your answer! I’m really bad at math but I do know how to do that!
The answer to your question is as follows
281.12
If you notice the terms, they're
7, -21, 63, -189 and so forth.
7*-3 = -21 and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.
now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 , you do have a convergent sequence.
however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.
