What can an archaeologist conclude about artifacts found in the same "strata" (a layer or a series of layers of rock in the ground)?
a
b
The artifacts were from a people with no technology.
Different people made the artifacts
The remains are from the same time period
The remains are from a different time period
С
d

The remains are from the same time period

Explanation:

Geological strata are rock layers that are formed through time. As time passes, new stratas are formed upon the old ones.

If an archeologist finds several artifacts in the same strata, it indicates that the artifacts are very likely to be from the same time period. This is why archeologtists study geology, and give great importance to the understanding of geological strata.

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

the first action that caused many creek indians to turn against william mcintosh was when mcintosh a) supported the united states during the creek war of 1813–1814. b) attempted to stop the sale of creek land to the u.s. government. c) seized control of over 1,000 acres of land belonging to the creeks.
