Answer:
The answer are
A.
B.
Step-by-step explanation:
To find the infers we do that
Answer:
1/343
Step-by-step explanation:
If you multiply 1/7*1/7*1/7 (1/7^3) then you would get 1/343.
L=7+w
P=(12x+14)=2(6x+7)
l+w= P/2 = 2(6x+7)/2= 6x+7
l+w=6x+7
2l = 6x+7
l = (6x+7)/2
l=7+w
-> w= l-7
= [(6x+7)/2] -7
= (6x+7-14)/2
= (6x-7)/2
Start from Start Here square, the pointer to the next question to resolve is given by the solution to the equation in the current square
The values of the Maze are as follows;
- x = 10
- x = 8
- x = -9
- x = 5
- x = 11
- x = 3
- x = -5
- x = 9
- x = 7
- x = -7
Reason:
The solutions are;
10·x + 15 = 12·x - 5 by alternate interior angles theorem
6·x + 6 = 5·x + 14 by alternate exterior angles theorem
x + 109 = 100 by corresponding angles theorem
11·x + 5 + 120° = 180° by same side interior angles theorem
11·x - 1 = 10·x + 10 by corresponding angles theorem
35·x + 5 = 110 by corresponding angles theorem
x + 85 + x + 105 = 180 by same side interior angles theorem
7·x - 3 + 12·x + 12 = 180° by same side interior angles theorem
19·x - 3 = 130 by alternate interior angles theorem
x + 67 = 60 by alternate interior angles theorem

Hello from MrBillDoesMath
Answer:
[email protected] = - sqrt(7)/ 4
which is choice B
Discussion:
This problem can be solved by drawing triangles and looking at ratios of sides or by using the trig identity:
([email protected])^2 + (sin2)^2 = 1
If [email protected] = 3/4
, the
([email protected])^2 + (3/4)^2 = 1 => (subtract (3/4)^2 from both sides)
([email protected])^2 = 1 - (3/4)^2 = 1 - 9/16 = 7/16
So...... taking the square root of both sides gives
[email protected] = +\- sqrt(7)/ sqrt(16) = +\- sqrt(7)/4
But is [email protected] positive or negative? We are told that @ is in the second quadrant and cos(@) is negative in this quadrant, so our answer must be negative
[email protected] = - sqrt(7)/ 4
which is choice B
Thank you,
Mr. B
