We'll solve this equation in order to find the score of the 4th test, which we denote with x.
. Solving it we find that x=63. And it is the final answer for this problem.
Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
Answer:
10 minutes = 1.047198 radians
10 minutes = 60 degree
Step-by-step explanation:
we know that
There is 60 minutes in an hour
so it is This is 2 Pi radians
so 10 minutes is 
or 
th of an hour
and here we know the hand will travel of the full circle
and we know A full circle measures 2 Pi radians
2 × pi radians = 360 degrees
10 minutes = × 2 × pi radians
10 minutes = 
× pi radians
10 minutes = 1.047198 radians
10 minutes = 60 degree
First, you should make a graph plotting "h" as the y-axis and "t" as the x-axis. Then, you can plot the equation they give you in the question.
Part A is asking about the slope of the graph. Basically, you need to find the rise over the run each second.
Part B is asking about the "h"-intercept, or the y-intercept. When Johnny first began his ride, exactly 0 seconds passed, and he was at the top of the hill.
Part C is asking you to find how long it will take to travel a third of the way down the hill. (I think the answer should be 5 seconds, but I'll leave it to you to figure out why.)
