Answer:
The speed of the faster cyclist is 15 miles per hour
Step-by-step explanation:
Let the speed of the slower cyclist be x miles per hour
The speed of the faster is 3 times this
Mathematically, we have this as 3 * x miles per hour = 3x miles per hour
Now;
distance = speed * time
In 4 hours, the distance covered by the slower will be;
x * 4 = 4x miles
The faster;
3x * 4 = 12x miles
Since they are riding opposite each other, they would have covered a total distance of 80 miles when they meet
Thus, we have that;
12x + 4x = 80
16x = 80
x = 80/16
x = 5
The speed of the faster is;
3x miles per hour
Substitute the value of x here
That will be;
3 * 5 = 15 miles per hour
Answer:
x=56
Step-by-step explanation:
okay so
x=180- (64+60)
x= 180-124
x= 56
Answer:
Option A
Step-by-step explanation:
where,
is the final value
if the initial value
R is the investors rate of return
so,
so the investors rate of return is -11.8%
In the graph,
Amplitude = 1.5 units
Period = 180°
The x-intercepts are 40°, 140°, 220°, and 320°
<h3>Determining x-intercepts </h3>
From the question, we are to determine the amplitude, period and the x-intercepts of the given graph
Amplitude is the distance from rest to crest.
In the graph,
Amplitude = 1.5 units
Period is how long from crest to crest OR trough to trough
In the graph,
Period = 180°
x-intercepts refers to the points where the graph cuts the x-axis
In the graph,
The x-intercepts are 40°, 140°, 220°, and 320°
