Ash from the volcano settled out of the atmosphere and covered an area of 157,000km ^2 assuming the ash was 1.00mm deep and evenly spread over the circular area centred on the volcano what is the volume of ash erupted from the volcano answer in m^3 and scientific notation

The magnitude M of an earthquake is given. a. Find the earthquake intensity I in terms of the zero-level earthquake intensity lo- b. Find the energy released by the earthquake. M = 7.3

The length (in centimeters) of a typical Pacific halibut t yr old is given approximately by the following.  f(t) = 210 (1-0.959e-0.2t) What is the length of a typical 8-yr old Pacific halibut?  (Round your answer to the nearest whole number.) ______________cm

If a 1.0 mm thick piece of plastic sheeting is being placed around a ball to represent 75 percent of the mass of Earth's atmosphere, what is the diameter of the ball needed to model Earth? Use 1.2756 x 10 km for the Earth's diameter and 12 km for the thickness of 75 percent of the mass of Earth's atmosphere. Express the answer in standard scientific notation. Dpall x 10 cm

An earthquake occurs 6,875 km from a seismograph. The P-waves arrive 11.6 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.8 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. vP = d  s vP = km/s

A tank has a rectangular base of 20 cm by 10 cm and a depth of 6 cm.    Estimate dV if you only fill it up to 5.5 cm.

W meters L meters A town has a large unused field, A rectangular portion of the field will be enclosed by a fence for a dog park, The park will be W meters wide and L meters long, where the length is two times the width. The park will be enclosed by a fence on all 4 sides, with an additional segment of fence running through the middle of the park, dividing it into two square areas. If a total of 1,400 meters of fence is used to enclose the park and divide it into the two square areas as described, which of the following systems of equations could be solved to determine the width and length of the park? W = 2L A 1 2W + 2L = 1,400 W = 2L 3W + 2L = 1,400 B

Was really confused on this and needing help please. I need to know what the trend line equation is, accepted value of the slope, and the % error for both objects.    Attaching all info below. Thank you so much!
