Answer:
13 + 2n
Step-by-step explanation:
Area of a triangle equals 1/2 base times height, or 1/2bh. So it would be 5.4 times 2, equaling 10.8. Then multiply it by 1/2, which would divide it by 2, resulting in 5.4 again. Just make sure to get your units right.
Answer:
14 7/12
Step-by-step explanation:
You take 6 3/4 and subtract 1/2 cup, which equals 6 1/4. Then you take 6 1/4 and divide that by 3. Then you multiply that answer (2 1/12) by seven.
If we have 2 dices rolling, we have all 6x6=36 different ways.
But for the sum of the two being 4, we have (1;3), (3;1) and (2;2), only 3 ways.
And we calculate the probability : 3:36= 1/12
