Phillip watched a beach vollyball game from 1 p. M. To 1:15 p. M How many degrees did the minute hand turn?

90°

Step-by-step explanation:

A full rotation on a clock would be 360° like a normal circle and this would represent a full hour.

When it comes to 15 minutes therefore, to find the number of degrees the time would turn, find out the proportion of an hour that 15 minutes is then relate it to 360°.

= 15 mins / 60 mins

= 1/4 hours

If an hour is 360°, 1/4 hours must be:

= 1/4 * 360

= 90°

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
