Similarity ratio is a ratio of two figures having the same side.
Ratio can be rate but rate can never be ratio. In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.<span>

Answer:
x= -2, x= -10
Step-by-step explanation:
x^2 + 12x + 36 = 16
Began by setting this quadratic equation to 0. To do this, in this equation you must subtract.
x^2+12x+20=0
Next, we plug this into the quadratic formula, where a in this case is 1(there is nothing in front of x^2), b is equaled to 12(there is a 12 as the coeefficient of 12x), and c is equaled to 20.
The quadratic formula is as goes:
(-b+-(this means plus or minus)√b^2-4ac)/(2a)
After pluggin in and simplifying, the answer is x= -2 and x= -10
Answer:
6 hours
Step-by-step explanation:
20(for babysitting)*6=120
120+5 (for gas)=125
$125=6 hours of babysitting
In the given triangle, the slope of line BC is (C) -1.
<h3>
What is the slope?</h3>
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
A line's slope is how steeply it slopes from LEFT to RIGHT.
The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.
No matter which two locations on the line you choose, the slope of a line is always constant (it never varies).
So, the slope of line BC:
Coordinates of BC are:
B: (-2, 6)
C: (4, 0)
Slope formula: m = y2-y1/x2-x1
Now, substitute the values and calculate as follows:
m = y2-y1/x2-x1
m = 0-6/4-(-2)
m = -6/6
m = -1
Therefore, in the given triangle, the slope of line BC is (C) -1.

Step-by-step explanation:
180 Degree Rotation
When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.
