16 % of tiles are black
<em><u>Solution:</u></em>
Given that floor tiles come in red, blue, and black
To find: percent of the tiles that are black
From given question,
number of red tiles = 16
number of blue tiles = 5
number of black tiles = 4
Therefore, total number of tiles = number of red tiles + number of blue tiles + number of black tiles
Thus total number of tiles = 25
<em><u>To percent of the tiles that are black, use the following formula:</u></em>
Thus 16 % of tiles are black
The ordered pair (-6,-9) will be located in quadrant IV.
The new points will be A' (-6,9) B'(-6,-3)C'(6,-3) then graph them. REMEMBER: if the scale factor is greater than 1 the image will shrink. If the scale factor is less than one the image will enlarge
Answer:
C)
Step-by-step explanation:
3 and 4 together have 180
Applying parallel line postulate twice
36degree=3x degree +2y degree
126 degrees=12 x degree + 2y degree
So, the two equations are:
3x + 2y = 36
and
12x + 2y = 126
Eliminate x to solve for y
-(3x + 2y)= -(36)
-3x - 2y = -36
Combine the equations
(-3x - 2y)+ (12x + 2y) = (-36) + (126)
-3x -2y + 12x + 2y = -36 + 126
9x = 90
x = 10
Plug value of x back into to the equations to solve for y
3(10) + 2y = 36
30 + 2y = 36
2y =6
y = 3
Optional
Plug x into the other equation to check for error
12(10) +2y = 126
120 + 2y =126
2y = 6
y = 3
