Answer:
ROCK 2.3 kg
is about 22.5N
Step-by-step explanation:
To convert kg>>>>N
You multiply by 9.8 (this is good for estimating, but use more decimal places like, 9.80665 for more exact calculations).
You can divide N÷9.8 to find kg
see image
The answer is (-2,-10) you just need to plug them in.

Answer:
A ≈ 530 cm²
Step-by-step explanation:
The swept area equals the total area covered by the blade minus the unswept area.
The area of a sector with radius r and angle θ is:
A = (θ / 360) πr²
So the swept area is:
A = (θ / 360) πR² − (θ / 360) πr²
A = (θ / 360) π (R² − r²)
A = (150 / 360) π (21² − 6²)
A ≈ 530 cm²
B.
because {1,1,3,5,8}
{2,2,4,6,9}
you're just counting the numbers after the one that was given to you.
