The answer is B because before mixing the solution together nothing happened and it wasn’t warm, now that kayden mixed the solutions causing a chemical reaction making it to become warm. There for it will be B

Answer:




Step-by-step explanation:
Given





Solving (5): E and F
Sets of E and F = E n F

List out common elements

<em>They are not mutually exclusive because </em>
<em />
Solving (6): F and G
Sets of F and G = F n G

List out common elements

<em>They are not mutually exclusive because </em>
<em />
Solving (7): F or G and P(F or G)
Sets of F or G = F U G

List all elements without repetition

Solving P(F U G)



Hence;

Divide by 3

Answer:
Step-by-step explanation:
In the first equation, -4 x -b should be postive 4b, so +4b, because a negative times a negative equals a postive
Question 1:
We can use the rule of exterior angle of triangle, where the exterior angle is equal to the sum of the other 2 interior angles of the triangle except for the adjacent one.
So, we can calculate angle 1 by adding up the 2 given angles.
Angle1 = 62° + 57°
=119°
=answer C.
Question 2:
We can also apply the rule above, but first we have to calculate the remaining angle of the triangle first.
For this, we have to use the angle sum of triangle. All 3 interior angles of triangle should add up to 180°.
Let that remaining angle be x.
X = 180° - 62° - 57°
X=61°
Now we can apply the rule of exterior angle of triangle.
Angle 1 = 62° + 61°
=123°
=answer D.
