Step-by-step explanations:
B. Karen only
ice cream : $8 a gallon
$8 times 5 equals $40
paperback novels: $8 each
$8 times 5 equals $40
$40 plus $40 equals $80 and Karen is the only one with $80.
Answer:
angle BEF = 100 degrees
Step-by-step explanation:
For a regular 9-sided polygon (nonagon),
each exterior angle = 360/9=40 degrees
each interior angle = 180-40 = 140 degrees.
Referring to diagram, in the trapezoid (trapezium) BCDE, the base angles are 180-140 = 40 degrees.
Therefore angle DEB = 40 degrees
that leaves BEF = 140-40 = 100 degrees
The second sentence above helps with this answer. The y-intercept is the initial height of the plant before any documentation of time and growth was collected. Since the plant was initially 5 cm high, we can use it as a starting point for the data. For example, using x=0 indicates 0 day and if we substitute it in you will see that we are left with a solution of 5. This will let those reading the data to understand that the plant was already at 5 cm when the experiment began.
