Answer:
Probability of randomly drawing a red marble is
Step-by-step explanation:
Given 5 red marbles, 8 blue marbles, and 12 green marbles in a bag. we have to find the 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
As Probability of an event is the chances of an event to occur. It is defined as the favourable outcomes by total number of outcomes.
As no. of red marbles are 5 and
Total number of marbles are 5+8+12=25 marbles.
Hence, probability of randomly drawing a red marble is

Since the area is that of a square, you know that all side lengths are the same.
Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².
The length of the side of a square with an area of 144 in² is 12 in.

Rational number.

This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.
Plug in your leg lengths:
a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4
