Answer:
7.85km
Step-by-step explanation:
Using Sine rule
Sin57° = distance / 18km
Therefore, distance = 18 x sin57°
distance = 7.85km
Answer:
5 mph.
Step-by-step explanation:
Let the runner travel at x miles an hour , then the cyclist travels at 5/ 3 * x
= 5/3 x miles an hour.
So we have the equation
5/3 x - x = 2 ( since the cyclist was travelling at 2 mph faster).,
2/3 x = 2
x = 3/2 * 2 = 3 mph.
So the cyclists speed was 3 * 5/3
= 5 mph.
67 clients has to pay to use the website.
<u>Solution:</u>
Given, Sid runs a website.
He charges each client $54.67 to use the website.
Creating the website cost sid $116.56.
He wants to make at least $3,546.33 in profits,
