There is a property called "Quotient of powers property", which states that:

Where "a" is the common base and "m" and "n" are exponents.
For this case, you have:

Then, in order to find the quotient, you must apply the Quotient of powers property. You need to write the common base (in this case is 3) and then subtract the exponents.
So, you get that the quotient is:
Answer:
12.5 unit square
Step-by-step explanation:
The area of a trapezoid is calculated with the following formula:
(b1 + b2)*h/2 (b1: base, b2: base, h: height)
(4+6)*(2.5)*2 = 12.5
Answer: The rock would still weigh 90lbs
Step-by-step explanation:
No, weight has being proven to reduce by the further you move from the center of the Earth. But since even the tallest buildings in the world or tallest mountains are a tiny fraction of the Earth’s radius, the difference in weight won’t be something that can be measured as it’s a tiny fraction. So the mass of the rock doesn’t change what changes is the gravitational force ( g ). So the rock would still end up weighing 90lbs even at the top of the tower because it is still within the earths atmosphere.
Answer:
The anser is C i did this
Step-by-step explanation:
D. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
