Assuming that this happened at the same environment like the time of day, then we can use ratio and proportion. We relate the height of the tree with its shadow by using the ratio of the biologist's height to his shadow.
Height of tree/Height of its Shadow = Height of biologist/Height of his Shadow
Height of tree/28 = 7/2
Height of tree = 7*28/2
Height of tree = 98 feet
The answer is D.

Answer:
Option D.
, 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal
so

substitute values and solve for OD


therefore
the coordinate of point D is 
the scale factor is equal to 
Answer:
Step-by-step explanation:
Ruth's salary is s(j), where s represents salary and j the number of jars she sells.
At the very beginning, she receives $50. Only answer 'd' could be correct.
But also, the equation has the variable part 0.65j, or
$0.65j, which is directly proportional to the unit price of the jars of jelly.
*
Summing up the fixed and variable parts, we get
s = $50 + ($0.65j), or s = $50 + ($0.65/jar)j This is Answer D.
