Answer:
-47
Step-by-step explanation:
For this problem, we can use the rule "two negatives make a positive".
-81-(-34)
= -81 + 34
If you subtract 34 from 81, you find the opposite positive/negative answer.
81 - 34 = 47
Change all of the positive/negative signs:
-81 + 34 = -47
Answer:
18
Step-by-step explanation:
70^2 = 4900 < 5607 < 6400 = 80^2
so sqrt(5607) is a two-digit number with tenth-digit 7
71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625
so the smallest square bigger than 5607 is 75^2, which is 5625
so the number should ne 5625 - 5607 = 18
Answer:
She deposits $350 into the account at the beginning of the year.
Step-by-step explanation:
Let us assume that Keegan deposits $P into her savings account at the beginning of the year.
The account earns 3% simple interest each year and she has $360.50 in her account at the end of the year.
If Keegan did not make any additional deposits or withdrawals during the year.
So, we can write that ![P[1+\frac{3}{100} ]= 360.50](https://tex.z-dn.net/?f=P%5B1%2B%5Cfrac%7B3%7D%7B100%7D%20%5D%3D%20360.50)
⇒ P = $350 (Answer)
