Answer: D. 3/64
Step-by-step explanation:
Answer:
14 tickets. Equation form : 500- 486=x.
Step-by-step explanation:
Variables are always the unknown. What you don't know from the given information is the number of tickets left to be sold. 54*9=486. So x is equivalent to 500-486 aka 14
Answer:
12 is the number of people in each group.
Step-by-step explanation:
12 would be the number of people in each group. because as you divide 60 to 5..... 12 people are divided sperately into 5 groups.. hope this helps and if you have any questions go ahead and ask! JESUS LOVES YOU
Answer:
Slope of the line 
Step-by-step explanation:
Given that,
The point 
lies on the curve 
.
If 
is the point lies on 
.
To find:- Find the slope of line 
.
So,
The coordinates of point when it lies on
if 
then 
So, ≡ 
and many points can be calculated by given Equation.
Using the formula when two points 
.
Then, substituting the coordinates we get,
⇒ 
Therefore,
Slope of the line 
Explanation:
The Law of Cosines specifies the relationship between the three sides of a triangle and any one of the angles. If the sides are designated a, b, and c, and the angle opposite side c is C, then it tells you ...
c² = a² + b² -2ab·cos(C)
This relationship can be used to find any and all angles, given the three sides of a triangle. Or, having found one angle using the Law of Cosines, the others can be found using the Law of Sines:
sin(A)/a = sin(B)/b = sin(C)/c
_____
Typically, inverse functions are required. That is, from the Law of Cosines, ...
C = arccos((a² +b² -c²)/(2ab))
And from the Law of Sines, ...
A = arcsin(a/c·sin(C))
B = arcsin(b/c·sin(C))
_____
<em>Note on solving triangles</em>
It often works best to make use of exact values where possible. It is also a good idea to start with the longest side/largest angle. Of course, once you have two angles the other can be found as the supplement of their sum.
