1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.
Answer: 0/5
Step-by-step explanation:
Answer: 70% or .7
Step-by-step explanation: there are 10 people total who have a brother and 7 of those people have a sister so 7/10=.7
A set of 3 nonzero whole numbers say (a,b,c) that form the sides of a right triangle and follow the pythagorous theorem

are called a Pythagorean Triple
The example of Pythagorean Triplet are
(3,4,5), (5,12,13) ,(8,15,17), etc.
Hence
A set of 3 nonzero whole numbers that form the sides of a right triangle are called a Pythagorean Triple.
