The ratio for the number of people that use an android phone to the number of people that use an iphone is 4: 5 if 56 people in the movie theater use and android phone, how many people would you expect to use an iphone show all work including labels and write a therefore statement

70

Step-by-step explanation:

If 56 people correspond to 4 ratio units, then each of those units stands for 56/4 = 14 phone users.

Therefore 5 ratio units stands for 5·14 = 70 phone users.

70 people are expected to be using an iPhone.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

stops on an even number.
