Answer:
9/2
Step-by-step explanation:
2/3 + 3/4 + 5/6 + 4/8 + 3/12 + 3/2 =
= 16/24 + 18/24 + 20/24 + 12/24 + 6/24 + 36/24
= 108/24
= 54/12
= 9/2
Answer:
4 Books
Step-by-step explanation:
3+1 = 4
16 - 4 = 12
3x4 = 12
Answer:
All I know for a fact is that number 10 is C
Step-by-step explanation:
Root root 20^2 - 4^2
X = 2
Answer:
2 sqrt(19)
Step-by-step explanation:
We know that the angle between the two hands
360 /12 *2 = 60 degrees
We divide by 12 because there are 12 number and multiply by 2 because there are 2 number between 10 and 12
This is a triangle where we know 2 sides and the angle between them.
We can use the law of cosines to determine the third side
c^2 = a^2 + b^2 -2abcosC
Where C is the angle between sides a and b
a =4 and b = 10 C = 60 and we are looking for side c
c^2 = 4^2 + 10^2 -2*4*10 cos60
c^2 =16+100 - 80cos 60
c^2 = 76
Take the square root of each side
sqrt(c^2) = sqrt(76)
c = sqrt(76)
c =sqrt(4) sqrt(19)
c =2 sqrt(19)
