Hello,
10*10=100>89
n=89 is prime if it not divisible by all prime less then its square root
0<89<100 ==>0<√89<10
The primes to test are 2,3,5,7.
89 does not end with a even digit ==> 89 is not divisible by 2
8+9=17 if not divisible by 3 ==>89 is not divisible by 3
89 does not end with 0 or 5 ==>89 is not divisible by 5
3*8+1*9=33 is not divisible by 7 ==>89 is not divisible by 7
So: 89 is prime.
Answer:
I think 3 ,4 ,and 5 are to only correct ones

The Midsegment Theorem states that the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side.
The answer would be B) 1.04%
Answer:
178
Step-by-step explanation:
Perimeter = distance all the way around the outside of a 2D shape
Missing vertical length = 45 - 14 - 17 = 14
Missing horiztonal length = 44 - 8 - 29 = 7
⇒ perimeter = 45 + 8 + 17 + 29 + (45 - 14 - 17) + (44 - 8 - 29) + 14 + 44
= 45 + 8 + 17 + 29 + 14 + 7 + 14 + 44
= 178
