Answer:
time = 1 hour 24 minutes
Step-by-step explanation:
Given that:
Eastbound train travels at a rate of 65 miles per hour
Westbound train travels at a rate of 85 miles per hour
So speed = 65 + 85 = 150 miles per hour
Total distance = 210 miles
We have to find the time
We know that
Distance = time * speed
OR
time = distance / speed
time = 210/150
time = 1.4 hours
Or it can be written as:
time = 1 hour 24 minutes

Answer:
B) - The Viceroy population remained fairly steady over the three years recorded.
C) - The average number of Zebra Swallowtails over all three samples will be less than the number recorded in year 1.
D) - If a population is increasing over time, the average will be less than the most recent count.

<h3>The value of x is 4.10</h3>
<em><u>Solution:</u></em>
Given that,
The angle Johnny holds his pen on paper creates a linear pair
Angles in a linear pair are supplementary angles
Two angles are supplementary, when they add up to 180 degrees
The measure of one angle is 13x + 7
The measure of the second angle is one less than twice the first angle
Therefore,
Measure of second angle = twice the first angle - 1
Measure of second angle = 2(13x + 7) - 1
Measure of second angle = 26x + 14 - 1
Measure of second angle = 26x + 13
Therefore,
Measure of first angle + measure of second angle = 180
13x + 7 + 26x + 13 = 180
39x + 20 = 180
39x = 180 - 20
39x = 160
x = 4.1
Thus value of x is 4.10
Answer:
C, E, F
Step-by-step explanation:
A is false because dilations can not only increase the length of line segments, but also decrease the length of line segments.
B is a true statement.
C is true because when angles undergo dilations, their "size" does not change.
D is false because dilations do not increase the measures of angles.
E is false because a triangle that underwent a dilation becomes similar, not congruent.
F is true because of E's reasoning.
