Answer:
<h2>
AC = 21</h2>
Step-by-step explanation:
Collinear points are points are points that lies on the same line. If point B is between A and C, then AC = AB+BC
Given AC = 21x, AB = 11 and BC = 11x-1, in order to find the value of x, we will substitute the given parameters in the relationship above to have;
Subtracting 11x from both sides;
Since AC = 21x
substituting x = 1 into AC,
AC = 21(1)
AC = 21
Answer:
Option C is false.
Step-by-step explanation:
Theoretical probability doesn't change with experiments.
Lets set up some variables:
- 1st envelope:
- 2nd envelope:
- 3rd envelope:
Now let us set up some equations based of the facts:
Now we could try some numbers out since there isn't really any other way I could solve this so far...
but we do know that the sum of and must be even since they equal
After you tried it out for a little bit, when = 2, then = 8, and . These three values meet the criteria and we have our answer.
Hope that helped!
Answer:
D. 73.48 m.
Step-by-step explanation:
The diagonal distance across the meadow
= √(30^2+30^2)
= √1800
tan 60 = h / length of the diagonal (where h = height of the pillar).
h = √1800 * tan 60
= 73.48 m
