Answer:
I can answer the first one the other 2 I can't make out.
Step-by-step explanation:
Firstly,
1) They are the same since they add one to the row every time
2) They are different because Megan's pattern is that they only count the first column in orange, and Kyle's pattern counts the number of blocks in each row.
3) They have the same number of blocks just in different colors in rows and columns.
Answer:
the probability is 0.125
Step-by-step explanation:
The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:
<u> 2 </u>* <u> 2 </u> * <u> 2 </u>* <u> 2 </u> = 16
1st turn 2nd turn 3rd turn 4th turn
Because the mouse can take two options at every turn, right or left.
Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:
1. right-right-left-left
2. left-right-right-left
So, the probability that a mouse will find an exit is:
Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
Answer:
The answer is x=2-(y/2)
Step-by-step explanation:
In the right triangle shown, m ∠ A = 30 ° m∠A=30°m, angle, A, equals, 30, degree and A B = 12 3 AB=12 3 A, B, equals, 12, squa

Answer:
AC = 18
Step-by-step explanation:
Given the question:
<em>In a right triangle, m∠A = 30° and AB = 12√3 (AB is the hypotenuse). How long is AC?</em>
Side AC is adjacent to angle A. Then, by definition of cosine:
cos(A) = adjacent/hypotenuse
cos(A) = AC/AB
AC = cos(A)*AB
AC = cos(30°)*12√3
AC = 18
