C = children, a = adults
c + a = 700...c = 700 - a
7c + 10a = 6400

7(700 - a) + 10a = 6400
4900 - 7a + 10a = 6400
3a = 6400 - 4900
3a = 1500
a = 1500/3
a = 500

a + c = 700
500 + c = 700
c = 700 - 500
c = 200

there were 200 children and 500 adults

The_________states that the sum measures of the interior angles of a triangle is 180​
serious [3.7K]

The Triangle sum theorem states that the sum measures of the interior angles of a triangle is 180 degree

<em><u>Solution:</u></em>

We know that,  

The Triangle Sum Theorem states that if you add all three interior angles, those are the angles inside the triangle, they would always add up to 180 degrees.

It is easy to remember that we add the three angle measurements to get 180 degrees because of the word sum in the name of the theorem. To make it short and sweet:

Consider a triangle with interior angles a, b, and c. Then we can say,

\angle a+\angle b+\angle c=180^{\circ}

The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem

If the probability of surviving a head on car accident at 55 mph is 0.097, then what is the probability of not surviving
BabaBlast [244]

The probability of not surviving a head-on car accident is: 0.903

Step-by-step explanation:

The probabilities of occurrence and non-occurrence of an event add up to one.

If p is the probability that an even will happen and q is the probability that it will not happen

Then

p+q=1

Here,

Probability of surviving = p = 0.097

Probability of not surviving = q = ?

0.097 + q = 1\\q = 1 - 0.097\\q = 0.903

The probability of not surviving a head-on car accident is: 0.903
