Answer:
first calculate the area of the arch using:
O/360×πr2
O represents theta
second calculate the area of the circle using πr2
finally minus the answer gotten from the two different areas
thats how u get the area of the shaded area
You're thinking b=1 will always give an integer, certainly true.
Then you think b=-1 will also always give an integer, so
Answer: ±1
Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers. The condition for an integer is
b | a
read 'b divides a' meaning a is a multiple of b.
Then you realize that a and b might not even b integers themselves.
Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.
Answer:
x=(10-k)÷6
Step-by-step explanation:
6x=10-k
x=(10-k)÷6
Answer:
y=12x-50
Step-by-step explanation:
Distribute 12, x, and 4
y+2=12(x-4)
1. y+2=12x-48
Subtract 2 from both sides
2. y=12x-50
An estimate helps you because you round 3.9 to 4 and 5.3 to 5 so then you can give a rough estimation
