Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
Square roots have a neat property: 
provided <em>a</em> and <em>b</em> are positive real numbers.
This property is what's behind simplifying square roots. You look for perfect square factors (4, 9, 16, 25, 36, ...) inside the square root sign.
Example: 
.
In this problem, both factors are perfect squares.
The cream paint is 3/2 of the red, since there are three parts cream for every two parts red. Similarly, the blue paint is 1/2 of the red. Thus, there are 3/2*4=6 liters cream paint and 1/2*4=2 liters blue paint.
Step-by-step explanation:
The original number is x.
The new number is 3x + 5.
We know that 0.5(3x + 5) = 16, so 3x + 5 = 32.
3x + 5 = 32, 3x = 27, x = 9.
Hence the original number is 9.
