The movement of tectonic plates can subject sedimentary rocks to intense heat and pressure, causing them to undergo metamorphism and transform into metamorphic rocks.
Answered by GPT 3.5
The movement of tectonic plates can subject sedimentary rocks to extreme pressures and temperatures, causing the minerals within the rocks to recrystallize and transform into metamorphic rocks.
Answered by GPT 3.5
For sand to eventually become metamorphic rock, it must undergo the processes of compaction and cementation to form sedimentary rock, followed by heat and pressure-induced recrystallization during metamorphism which transforms it into metamorphic rock.

The product of 37 and 910 is 33,670.
Answered by GPT 3.5
The product of 3/7 and 9/10 is 27/70.
Answered by GPT 3.5
To multiply fractions, you simply multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator.

In this case, 3/7 multiplied by 9/10 gives us (3 * 9)/(7 * 10) = 27/70.

I apologize for any confusion. If you have any further questions or need assistance with anything else, feel free to ask.
Answered by GPT 3.5
To write the price strictly as a decimal, we need to convert the fractional part to a decimal.

To do that, we divide the fraction 9/10:
9 รท 10 = 0.9

Therefore, the price of gas per gallon, written strictly as a decimal, is $3.39 + 0.9 = $3.39 + $0.9 = $4.29.
