Answer:
28.2941 feet
Step-by-step explanation:
First we need to imagine a triangle with Justin and his shadow, and the tree and its shadow (as shown in the figure attached)., and then calculate the relation between Justin's height and his shadow's height
The relation between the opposite cathetus (height of Justin) and the adjacent cathetus (height of the shadow) is the tangent of the angle, so:
tan(angle) = 74/102 = 0.7255
The tree and its shadow will have this same angle and therefore this same relation, so:
0.7255 = tree / 39
tree = 0.7255 * 39 = 28.2941 feet

Step-by-step explanation:
she could make 9 mugs, (3/4 x 9 = 12)
she could make 1 small bowl, 1 small plate, 2 large bowls and 2 mugs. (2.5 + 1.5 = 4, 3.25 x2 = 6.5 .75 x 2 = 1.5; 4+ 6.5= 10.5 10.5 + 1.5 = 12) etc
If a student tells me that an argument that has a false hypothesis cannot be valid, I would reply that we need to look carefully at the meaning of validity in the context of logic. In everyday speech, we tend to use “valid” to mean the same thing as “true” or “accurate.” In logic, this is not the way the term is used.
