If the ratio of boys to girls in a class is 8:5 you will not be able to tell how many students are in the class because there could be 8 boys and 5 girls in the class or there could be 16 boys and 10 girls.
Alright, so you know that the formula for the area of a triangle is a=bh/2
First start out by identifying your base and height.
Base is the side that the shape is "standing on", in this case, that would be 9cm.
Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.
Now, plug these values into your formula
(12)(9) /2 = 54 cm squared! hope this helps :)
The distance between the two points is 
Explanation:
Given that the two points are 
and 
We need to determine the distance between the two points in simplest radical form.
The distance between the two points can be determined using the distance formula,
Let us substitute the coordinates and in the above formula, we get,
Simplifying the terms, we get,
Squaring the terms, we get,
Adding, we get,
Simplifying, we have,
Thus, the distance between the two points in simplest radical form is
Answer:
[2.5 ,4]
Step-by-step explanation:
The graph in this interval has a vertex while opening up wich means it's a minimum
You can use the Angle-Side-Angle (ASA) Congruence Postulate to prove the triangles are congruent.
