A scientist finds hominid fossils in China and in Australia. Judging by the rock layers in which both the fossils were found, the scientist suspects that they are approximately the same age. What should the scientist do next to build a stronger case that the fossils are the same age?

Answers

Answer 1

Answer: Since the fossils are of hominid origin, this means that they could contain carbon. Knowing this, carbon dating could be used to determine the age of the fossil. The technique is based on the ratio on carbon-12 and carbon-14. Carbon-14 undergoes radioactive decay, which is modeled by a first-order reaction. Knowing the half-life of carbon-14, one can solve the age of the fossils.

The table and the graph each show a different relationship between the same two variables, x and y:A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,180 and 4,240 and 5,300 and 6,360. On the right of this table is a graph. The x axis values are from 0 to 10 in increments of 2 for each grid line. The y axis values on the graph are from 0 to 350 in increments of 70 for each grid line. A line passing through the ordered pairs 2, 70 and 4, 140 and 6, 210 and 8, 280 is drawn. How much more would the value of y be in the table than its value on the graph when x = 11? 110 150 215 275

If the volume of a cylinder is 75pi cubic inches and the height is 3 inches then what is the radius of the base of the cylinder?

Answers

The formula for the volume of a cylinder is:

V=π*r²*h

We already know that...

V=75π
&
h=3in
so we can solve for the radius

V=π*r²*h
75π=π*r²*3
Divide both sides by pi
75=r²*3
Divide both sides by 3
25=r²
find the square root of both sides
5in=r

The radius of the base of the cylinder is 5in

Answer= 5in.
