Answer:
<u>1000 times more powerful</u>
Step-by-step explanation:
Each level n the scale is 10 times more intense than the previous, (10 * 10 * 10 = 1000) hence, 8 on the richter scale is 1000 times more intense than a 5 on the scale.
<u>Hope this helped :)</u>
This problem can
be directly solved by ratio and proportion.
We know that there
are 646,449 people for every 68.3 square miles, so:
646,449 people : 68.3
square miles = X : 570,374 square miles
We know that the :
symbol signifies division therefore,
646,449 / 68.3 = X
/ 570,374
X = 5,398,502,224

80 increased by 15% is 92.
80 x .15 = 12
12 + 80 = 92
Answer = 92
Answer:
<em>y = ( </em><em> )³ </em>
Step-by-step explanation:
log(y) + 3log(x) = 3
log(y) + log(x³) = 3
log(x³y) = 3
(y) + 3 (x) = 3
(y) + (x³) = 3
(x³y) = 3 ⇔ 10³ = x³y ⇔ <em>y = ( </em><em> )³ </em>
