Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
?=115-50=65°
It would be 2^12 (to the twelfth power) What you do is you multiply the power that's inside of the parentheses and the one on the outside. Since they are both negative, the power will end up being positive. And if you need to multiply it out, it would be 4096.
Answer: -1
Step-by-step explanation:
If k is equal to negative one then we can input it into it for the exponent and solve.
If multiplying exponents and they have the same base then you will just add the exponents and let the exponents stay the same.
The exponents are -3,1, and -1 add them.
-3 + 1 - 1 = -3
The base is 10 so we will raise 10 to the negative 3rd power.
Answer: 2,500 people per square mile
Step-by-step explanation:
Population density is calculated by : Population / square miles
Therefore :
Population density = 400,000/160
= 2,500
