Find the simple interest if you invest $568 at 16% for 8 months.
Lilit [14]
Ello! The answer is $60.59, because if you do

568x 0.16x 0.666667 = 60.58669696

Now, you obviously can’t type out all those numbers so you simplify which gets you 60.59!


I hope this helps you! :)

 First by breaking down the numbers:
 5,670,249,114 = 5,000,000,000 + 600,000,000 + 70,000,000 + 200,000 + 40, 000 + 9,000 + 100 + 10 + 4  which means the Value of 2 is 200, 000<span>2. Second, by using the ones words:
5,670,249,114 = 5 billion + 6 hundred million + 70 ten million + 2 hundred thousand + 4 ten thousand + 9 thousands + 1 hundreds + 1 tens + 4 ones  which means the Value of 2 is 2 hundred thousand

URGENT!!!! Find the m&lt;2.
Leto [7]

Answer:

Hello! :) I hope I’m correct!!

Step-by-step explanation:

<em>I think the answer should be the second one.</em>

<u><em>the angle with the square at the corner is obviously a right angle, 90°. opposite angles have the same angle so opposite to it, angle 3 is also 90°. then add the angle 3 and the given angle (23°). 90°+23°=113° then subtract it to 180° (since a straight line is 180°). 180°-113°=67°</em></u>

<em />

<em>The steps:</em>

<em>To solve m< 2,</em>

<em />m< 2 = 180 - (90 + 23)<em />

<em />m< 2 = 180 - 113<em />

<em />m< 2 = 67<em />

<em />

<h3><em>Therefore, I think the answer should be 67 (second choice)</em></h3>

<em>i’m not really sure if this is the answer, but I hope this was helpful!! :)</em>

<em>if you have any questions about these steps, feel free to ask!</em>
