List the 3-membered subsets of the set {1,2,3,4,5,6).

The water level at Lake Penny changed −1 1/10 in. this year. Next year, it is predicted to change another −1 2/5 in. What is the

romanna [79]

add 1 1/10 + 1 2/5

first get both fractions with the same bottom number: 2/5 = 4/10 ( multiply both numbers by 2)

so now you have 1 1/10 + 1 4/10 = 2 5/10

5/10 reduces to 1/2

so answer is 2 1/2 inches, and since the level is going down it would be negative 2 1/2 inches

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Leg a = 9

Leg b = b

Leg c = 12

Step 2: Solve for b

Substitute in variables [Pythagorean Theorem]: 9² + b² = 12²
[Subtraction Property of Equality] Isolate b term: b² = 12² - 9²
Evaluate exponents: b² = 144 - 81
Subtract: b² = 63
[Equality Property] Square root both sides: b = √63
