The district of columbia has a very high population density. there are 646,449 people in 68.3 square miles

b) alaska is 570,374 square miles in area. if alaska had the same population density as the district of columbia, how many people would live in alaska?

struggling with this question explain full detail for 20 points

This problem can be directly solved by ratio and proportion.

We know that there are 646,449 people for every 68.3 square miles, so:

646,449 people : 68.3 square miles = X : 570,374 square miles

We know that the : symbol signifies division therefore,

646,449 / 68.3 = X / 570,374

X = 5,398,502,224 people

answer: jasmine will bake 4/3 or 1 1/3 cookies in an hour

step-by-step explanation:

if u add 1/3 every 15 minutes after an hour u will have 4/3 or 1 1/3

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
