Seismologist have just registered a large underwater earthquake near sand point, alaska, that is big enough to produce a tsunami. the ocean depth is unknown but it took five hours to reach monterey california. estimate the depth of the ocean where the tsunami originated.

4002.79 m

Step-by-step explanation:

The distance between Sand Point, Alaska and Monterey California is 3,567 km. The distance velocity equation is given by

d=vt

3567=v*5

v=3567/5=713.4 km/hr=198.16667 m/s

Wave Speed Formula is given by

where g is the gravity acceleration 9.8 m/s and d is depth, solving for depth we have that

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
