Answer:
C. . how old they are
Step-by-step explanation:
Geologist are people that deal with the internal structure of the earth.
They study Rocks, and it's deposit accumulated millions of years back.
They can also give account of what happened in the past and the types of organisms that existed in the past.
Fossils are traces of event, remains of dead animals and decomposed object.
So geologist can give account of how many years a particular fossil has lived in that particular environment.
Answer:
Isosceles Right Triangle
Step-by-step explanation:
We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.
Everyone works differently in mental meth.
To calculate 9*52, we note that 9=10-1, so mentally calculate
9(52)
=(10-1)(52)
=520-52 [ subtract 20 from each number]
=(520-20)-(52-20)
=500-32
=468.
Alternatively,
9*52=9*50+9*2=450+18=468
If you're good with multiplication and division,
9*52=3*3(52)=3*156=450+18=468
Answer:
The correct answer is d) the ratio of the change in y to the change in x along the line.
We can tell this by looking at the slope formula.
m (slope) = (y2 - y1)/(x2 - x1)
