Answer:
1
Step-by-step explanation:
Given triangle ABC with vertices at points A(2,-4), B(4,-4) and C(4,-2).
1. Rotate this triangle anticlockwise by 90° angle over the origin. This rotation has the rule
then
2. Reflect triangle A'B'C' across the y-axis. This reflection has the rule
then
These are vertices of triangle 1
Before it rebounds n times we have the inequality
36 (3/4)^n < 1
(3/4)^n < 1/36
n ln 3/4 < ln 1/36
n < ln 1/36 / ln 3/4
n < 12.46
so n = 12
answer is 12 bounces
20×3 is 60 and if Sarah counted 45 beats in 20 seconds you'd multiply 45 by 3 so it would be 135.
Answer:
The answer is: The largest number is 15.
Step-by-step explanation:
Let n = the number
n + (n + 1) + (n + 2) + (n + 3) = (n + 4) + (n + 5) + (n + 6)
4n + 6 = 3n + 15
n = 9
Proof:
9 + 10 + 11 + 12 = 19 + 23 = 42
13 + 14 + 15 = 27 + 15 = 42

The probability of one head must be 3/8. I believe there is a 50% chance of getting a toss of more then 1 head in 3 tosses.
