Answer:
c
Step-by-step explanation:
The tree diagram shows that there are a total of six sample
spaces.
math------science
art
science---math
art---math

math
science---art
Based on the tree
diagram, the probability that the science project is first is two over six.
This is because science appears first in two out of the six sample spaces (boldened).

4. To determine if a triangle is a right triangle, given that you know the length of its sides, you have to check if its lengths follow the Pythagorean theorem.
This theorem states that the square of the hypothenuse (c) is equal to the sum of the squares of the legs of the triangle (a and b), following the expression:

The triangle is:
We have to check that a²+ b² is equal to c².
The square of the hypothenuse is:

The sum of the squares of the legs of the triangle is:

As you can see, the sum of the squares of the legs of the triangle is 100, which is the same as the square of the hypothenuse. The triangle follows the Pythagorean theorem and can be considered a right triangle.
The first 5 multiples of 15 are: 0, 15, 30, 45, 60
