Answer:
A). 18.84 radians per minute
B). 376.80 feet per minute
Step-by-step explanation:
As we know carousal is moving with 3 revolutions per minute.
(a). Angular speed = 3 revolutions per minute
= 3 × (2π) per minute
= 6π per minute
= 6×(3.14)
= 18.84 radians per minute
B). Since linear speed = Radius × Angular speed
= 
= 20 × 18.84
= 376.80 feet per minute
Let's remember orders of operations as we go through the craze of this problem.
We need to multiply or divide from left to right.
3w-6w+3w×7×7×6×5÷9+2
3w-6w+21w×7×6×5÷9+2
3w-6w+147w×6×5÷9+2
3w-6w+882w×5÷9+2
3w-6w+4,410w÷9+2
3w-6w+490w+2
-3w+490w+2
487w+2
To check that we simplified the expression right, I like to put in 1 for w and test it in the original expression and then the simplified expression (not needed).
487+2=489
3-6+3×7×7×6×5÷9+2=489
So that expression equals 487w+2.
Yes, Bryan is correct.
Because 4 is in the hundreds place.
The value of a digit in the number is the digit multiplied by the place value.

Answer:
Step-by-step explanation:
When you reflect over the line y=-x, you flip the x and y coordinate and multiply them by negative one, so for example (2,3) would become (-3,-2) or (-1,7) would be (-7,1). Using this rule you can find the new point for each point in the figure. The point lying on (-2,1) would be reflected to (-1,2). The point on (-4,1) would move to (-1, 4). The point on (-4,-1) would be moved to (1,4). The point lying on (-3,-1) would be reflected onto (1,3). The point on (-3,-2) would be on (2,3). Lastly, the point on (-2,-2) would be reflected to (2,2). i hope this helped lol. :)
