Step-by-step explanation:
You cannot assume that those are the only families that would want to go; you have to ask all the families.
I don't know the answer, but I suggest downloading the app: PhotoMath. It scans a math problem and shows you how to complete the problem. I hope this helped~!
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.
So, if you just multiply these you get 9.36*10000, which is 93600.
Answer:
Step-by-step explanation:
Using the distance formula, we see that the distance between (-4,4) and (-7,3) is .
The radius is half the diameter, so the formula would be r=d divided by 2
