The two numbers are 0.85 and 0.15
if you add them together you get 1, 0.85+0.15=1
and if you subtract them you get 0.7, 0.85-0.15=0.7
Answer:
15
Step-by-step explanation:
I beleive you just count the dots thats what i did
sqrt (3) * sqrt(16) = 4sqrt(3) = irrational
2sqrt(9) *sqrt(4) = 6*2 = 12 rational
7 sqrt(3)* sqrt(3) = 7*3 =21 rational
sqrt(5) * sqrt(5) = 5 rational
Answer: B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)
Step-by-step explanation:
The greatest common factor of two or more numbers is the highest number that divides all of them.
Given numbers : 72 and 81
Prime factorization of 72 and 81:
72 = 2 x 2 x 2 x 3 x 3
81= 3 x 3 x 3 x 3
GCF(72,81) = 3x 3 =9
Consider 72+81 = 9 x 8 + 9 x 9 [72= 8 x 9, 81 = 9 x 9]
= 9(8+9)
Hence, B. GCF of 72 and 81 is 9.
C. 72+81 = 9(8+9)
Answer:
1/6 but it kinda depends on how you throw it to give them all an equel chance of being the number you get.
