Answer:
You have to put energy into a molecule to break its chemical bonds. The amount needed is called the bond energy. After all, molecules don't spontaneously break

Answer:
18.66521%
Step-by-step explanation:
It seems all of the numbers are duplicated, the correct number should be 7%, 14 corner kicks, and 2 opportunities.
The team has 7%(x=0.07) chance to score so that means the chance to not scoring will be: y= 1-x = 100%-7%= 93%. There are 14 opportunities and we want to know the probability to get exactly 2 scores. The calculation will be:
P(x=2)= 2C14 * x^2 * y^12
P(x=2)=91 * 0.07^2 * 0.93^12= 18.66521%
Answer: x= -10 and Y=-20
Step-by-step explanation:
If y is equal to 2x that mean you need to substitute Y=5x+30 like this 2x=5x+30
Answer:
The correct option is C) x + y + z = 180 degrees
Step-by-step explanation:
Consider the provided information.
It is given that four r, x , y and z.
If x , y and z are the interior angle then,
According to the Angle sum property of triangle: The sum of three interior angles of triangle is 180°.
Therefore, the sum of x , y and z must be equal to 180 degrees.
Hence, the correct option is C) x + y + z = 180 degrees
Answer:
The correct answers are
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
Step-by-step explanation:
Given:
Distance represented by Y axis in kilometer.
Time represented by X axis in hour,
The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).
In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.
Therefore, the given below two options are correct
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
