Dr. black is standing 20 feet from a streetlamp. the lamp is making his shadow 5 feet long. he estimates that the angle of elevation from the tip of his shadow to the top of the streetlamp is 30. to the nearest foot, the streetlamp is about

the base of the triangle would be 20 +5 = 25 feet

 the angle of elevation is 30 degrees

 multiply tan(30) by 25 = 14.433

 rounded to nearest foot = 14 feet

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
