Answer:
3.29ft/mi
Explanation:
The gradient of a river is the slope through which a river flows. It measures the vertical drop in elevation of river to the horizontal distance.
Mathematically;
River gradient = 
Elevation = 1229ft
Horizontal distance = 373miles
River gradient = 
= 3.29ft/mi
Well if you mean what does the controlled part of a scientific investigation, it is the part of the investigation that will be your control or your base, untouched, original, data and such.
The tax to $2.99 would be the extra 1 cent you would have to pay so that it would become $3.00. Additional tax may be added like 6 cent or something but that only depends on the store or place you go to.
Answer:
Before opening another location in a new city, business owners need to research and determine various factors that could impact future sales and profit margins such as labor costs, tax implications,and logistics.
To find the epicenter (the point on the earth's surface where an earthquake begins) during earthquakes, one need to view the seismogram (a record of the ground motion), and at least two other seismographs recorded for the same earthquake. Other instruments such as a map, a compass for sketching circles on the map, a ruler, and a pencil will also be used.
The following are the steps of the triangulation process in the correct order to find the epicenter during earthquakes:
Step 1: Subtract the time of P wave arrival from S wave arrival.
Step 2: See what the time difference is equal to in distance on a seismic wave chart.
Step 3: Draw circles representing the distances from at least three seismograph stations to the epicenter on a map.
Step 4: Find the point where all 3 circles intersect, and you've found the earthquake's epicenter.
