Riley just opened a checking account at the bank. within the first month, she deposited three checks for $34.98, $51.02, and $51.22. she withdrew $5.23 for new pencils, $10.22 for earbuds, and $7.89 for movies from her account in the same month. write riley’s withdrawals as negative rational numbers and her deposits as positive rational numbers. order the rational numbers from least to greatest and explain your reasoning. at the beginning of the month riley’s balance was $128. what was her balance at the end of the month after all of her deposits and withdrawals? show your work

Look below

Step-by-step explanation:

Write Riley’s withdrawals as negative rational numbers and her deposits as positive rational numbers.

Deposits: (Q1)

 -34.98, -51.02, -51.22

Sum of negative rational numbers:

-137.22

Withdrawal's (Q1)

+5.23, +10.22, + 7.89

Sum of withdrawal's: 23.34

(Q2)-

W: 5.23, 7.89, 10.22

D: -51.22, -51.02, -34.98

Reason: Negative #'s go from lowest to highest (if you are ordering them from highest to lowest) because -34.98 is closer to 0 then -51.02

(Q2) If you are trying to order including each set of #'s it would be:

From least to greatest -51.22, -51.02, -34.98, 5.23, 7.89, 10.22.

(Q3) First, find her sum of the deposits and withdrawals.

Add these: -51.22, -51.02, -34.98, 5.23, 7.89, 10.22.

The answer to that would be $-113.88

Don't forget the tricky negative there. That means that she WOULD be in debt 113.88 dollars. But

Her balance at the beginning of the month was $128. So from there all you have to do is subtract 128-113.88 which gets you a total o: $14.12 .

Lol I worked rly hard on this. Could you do ya boi a favor and give it a big thx ;P or brainliest even?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

i belive those are the ones that are under 90 degreese.
