Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
Hence, the rotational speed is 0.38 rotation per second.
Answer:
Step-by-step explanation:
Let, the numbers = x, (x+2), (x+4)
x+x+2+x+4 = 63
3x+6=63
3x=57
x = 19
so, smallest number would be 19
You have a bunch of interesting figures there (check the diagram):
- square (in red)
- parallelogram (in green)
- Isosceles trapezoid (in yellow)
- Isosceles triangles (blue, and purple)
Notice that you have more than one of the same figures: a bunch of small isosceles triangles, tow isosceles trapezoids, two big isosceles triangles... etc.
If the interst rate is 2% per year and she paid it back after 3 years , it means she paid an extra 6% of $2000 just in interests.
Now we just need to find how much 6% is and add to 2000.
to discover the value of 6% of 2000 we can divide it by 100 ( to find 1%) and then multiply it by 6 ( to find 6%) :
2000 ÷ 100 = 20
1% = 20
6% = 20 × 6
6% = 120
Now add 120 to 2000 to find out how much she paid in total:
2000 + 120 = 2120
Awnser : She paid the total of $2120 over 3 years
I hope you understood my brief explanation. And please consider marking this awnser as Branliest. Thank you ! :)
