Answer:
C. 55s
Step-by-step explanation:
I'll refer to Wyndham as W and Michael as M.
Also, we will be assuming constant speed for both runners.
So, first of all, W ran with a speed of 8m/s;
400m/50s = 8 m/s
M ran with speed 9.2635.... m/s;
400m/43.18s = 9.26.... m/s
The difference is 1.26.... m/s, meaning every second, the distance between M and W would increase by 1.26.....m, starting from 0 at the start line;
9.26... - 8 = 1.26....
So, to find the desired distance, we simply multiply 1.26... by 43.18;
1.26... × 43.18 = 54.560....
(Rounded up to 55s)
Answer:
About 706.5 ft.
Step-by-step explanation: The formula for area of a circle is the radius squared (multiplied by itself) times 3.14. So 15 times 15= 225, times 3.14=706.5
Answer:
<span>If two lines intersect, then their intersection is exactly one point
Explanation:
Let's take a look at the choices:
Choice A: </span><span>A line contains at least two points.
The statement is true. However, it is not related to intersection between lines. Therefore, this choice is wrong
Choice B: </span><span>Through any two different points, exactly one line exists
This postulate is true. However, it does not relate directly to the intersection between lines. Therefore, this choice is wrong
Choice C: </span><span>If two lines intersect, then their intersection is exactly one point.
This statement is known as theorem 1-1. It describes the intersection between two lines.
Therefore, this statement is correct.
Choice D: </span><span>If two lines intersect, then exactly one plane contains both lines.
The conclusion given is related to points created due to intersection between lines. This option is therefore excluded as it describes planes.
Hope this helps :)</span>
Answer:
Dream Studio offers music lessons at $12 per lesson. Fox Studio offers music lessons at $9 per lesson. The better deal here would be Fox Studio. This is because Fox Studio offers cheaper lessons. For eight lessons at Dream Studio it costs $96, where as eight lessons at Fox Studio costs only $72.
Explanation:
Step 1 - Find the cost per lesson at Dream Studio
60 / 5 = 12
So, $12 per music lesson at Dream Studio.
Step 2 - Find the cost per lesson at Fox Studio
72 / 8 = 9
So, $9 per music lesson at Fox Studio.
Step 3 - Find out which offers a better deal
•Dream Studio = $96 for eight music lessons
• Fox Studio = $72 for eight music lessons
