I only know how to do # 7.
7. 4.5^2 + 6^2 = 7.5^2
20.25 + 36 = 56.25

Answer:
a) $0.500 ; (b) $5
Step-by-step explanation:
(a) 11 pound of flour =$5
1 pound of flour = $5/11
1 pound of flour = $0.500
(b) 8hours =$40
1 hour =$40/8
1 hour = $5
If I understand what you are asking, the number 5 is prime. The definition for a prime number is a number that has no factors other than itself and one. The prime factorization of 5 is 5 * 1. Since 5's factors are only itself and 1, that means that it is prime. The definition of a composite number is a number that has at least one divisor other than one and itself. This means that a number cannot be both prime and composite.
