Pennslyvania has approximately 1.28×107 people living in it. The population of the entire United States has approximately 3.28×108
people. About how many times greater is the population of the United States than the population of Pennslyvania. (write your answer in standard form)

1.28*107 = 136.96

3.28*108 = 354.24

354.24 - 136.96 = 217.28

The united stats population is 217.28 times greater than pennslyvania

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
