If I'm understanding the question correctly, this is how I would estimate the sum.
I would round each number to the nearest tens place.
33 would be rounded down to 30.
89 would be rounded up to 90.
Then I would do 90+30.
Answer:
The answer to this question is 68
Answer:
21n=
n-number and since its a number (n) and 21 you would put 21n
A=(1/2)(r^2)(sin[360/n])(n)
A=(1/2)(8^2)(sin[360/15])(15)
A=(1/2)(64)(sin[24°])(15)
A=(1/2)(64)(0.40673664)(15)
A= 195.2335872
Answer:
2.675 or 107/40
Step-by-step explanation:
- 3/4 x (2 2/5 - 5/6)
