vivado [14]

Answer:

A.  

x + y = 28

1.68x + 2.44y = 54.64

Step-by-step explanation:

Let x = paperback books and y = hardback books

x+y =28

We know that paperbacks cost 1.68 and hardback cost 2.44

1.68x + 2.44y = 54.64

We have 2 equations and 2 unknowns

x+y =28

1.68x + 2.44y = 54.64

Vesna [10]

Answer:

D. naturalistic observation

Step-by-step explanation:

Naturalistic observation is a method of research that consists in observing subjects in their natural environment without any exterior interferences that could alter their behavior. By posing as a student, Dr. Jimand is inserting himself among the other students to observe their natural behavior. For instance, if they were told that there was a doctor observing them, the students' behavior could change and that wouldn't be a true naturalistic observation.

The area of a triangle whose height is 1 more than 6 times its base is 13 square feet. If the base of the triangle is x feet, wh
pogonyaev
We must know that the are of the triangle is given by definition by
 A = (1/2) * (b) * (h)
 where 
 b = base 
 h = height 
 Substituting the values 
 A = (1/2) * (x) * (1 + 6x) 
 A = (1/2) * (x + 6x ^ 2) 
 Since the area is 13 then 
 (1/2) * (x + 6x ^ 2) = 13 
 Clearing x we have 
 6x ^ 2 + x = 26 
 6x ^ 2 + x-26 = 0 
 (x-2) * (x + 13/6) = 0 
 As we look for the base of a triangle then x> 0 
 x = 2 
 answer 
 the base is x = 2
 
 6x ^ 2 + x = 26
