Answer:
Your answer is D. 16 3/4
Step-by-step explanation:
10 1/12 + 6 2/3 = 67
4
= 16 3/4
= 16.75
Calculation steps
Conversion a mixed number to a improper fraction: 10 1/12 = 10 · 12 + 1/12
= 121/12
Conversion a mixed number to a improper fraction:
6 2/3 = 6 · 3+2/3
= 20/3
Add: 121/12 + 20/3 = 121/12 + 20 · 4/3 · 4 = 121/12 + 80 12 = 121 + 80/12 = 201/12 = 67/4
top:
(2x - 3y)^2
= 4x^2 - 12xy + 9y^2
bottom:
(3y - 2x)^2
= 9y^2 - 12xy + 4x^2
= 4x^2 - 12xy + 9y^2 (same as top)
so
(4x^2 - 12xy + 9y^2) / ( 4x^2 - 12xy + 9y^2) = 1
Ava is not correct. If you look at the denominator on her work:
[-(2x – 3y)]^2
= [(-1 )(2x – 3y)]^2
= (-1)^2 (2x – 3y)^2
= (2x – 3y)^2
so (2x – 3y)^2 / (2x – 3y)^2 = 1
The correct answer is 1
Answer:
25%
Step-by-step explanation:
There are 4 cards. Each one is a different number.
Only one card is a 9.
p(9) = 1/4 = 0.25 = 25%
The probability of the door opening within three attempts is the answer. C
I would say it’s the first one because if you round it it is going to be approximately 12 so that is my reason and also why it isn’t number two is because if you subtract 13.26 and 7.98 you get 5. Something so that’s why
