√x&lt;4 A.20 B.12 C.2 D.-1 E.5. F. No solution
evablogger [386]
We know that for √x to be meaningful, we must have x ≥ 0.

If we square both sides of the inequality, we have
  x < 4²
  x < 16

Thus the whole solution is
  0 ≤ x < 16

The following choices are valid solutions to the inequality:
  B. 12
  C. 2
  E. 5

The amount of time it takes p people to paint d doors varies directly with the number of doors and inversely with the number of
Talja [164]

Step-by-step explanation:

time ∝ number of door 1

time . ∝ 1/number of people. 2

compare equation 1 and 2

time . ∝ number of door / number of people

put k as constant

time = k number of door / number of people. 3

time =2. people=4 door = 10

putting in equation 3

2 = k (10)/(4)

2×4/10 = k

8/10 =k

4/5 =k

putting in equation 3

time= 4/5 number of door / number of people

now time =5 door= 25 people=?

5=4/5 (5)/ (number of people)

number of people =4/5 ×25/5

number of people= 4
