Serving to estimate the height of a parking garage using a 50 yards-long rope. sie oor while Sarah stands on the top level of the garage. Each holds an end of the rope. Joshua walks away until the rope is

completely dense, making a 30 angle with the floor and 60° with the garage wall.

Joshua says the height can be calculated using the function sin (30- and determines the height is 25 yards.

Sarah says the correct expression to be used is cos (60) and her calculation is that the height is 25 yards.

Which one is correct?

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

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

i cant answer this, theres no table. sorry man
