7.75+4.50
Then this equals 12.25 ; You gone want to divide this
519.25 \ 12.25 you get $42.38 or $42.39 if you round.
Or 4.50 x 60 is $270
7.75 x 30 is $232 which is closet to $519.25 which will give u $502.50

Answer:
the answer is -25
Step-by-step explanation:
-5 x -5= -25
negative x negative= negative
Answer:
The ratio of the intensities is roughly 6:1.
Step-by-step explanation:
The intensity I() of an earthquake wave is given by:
<em>where P: is the power ans d: is the distance. </em>
Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:

<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km </em>

Therefore, the ratio of the intensities is roughly 6:1.
I hope it helps you!
