First step is to find the circumference of the wheel (pi x diameter)
The radius is half of the diameter so 2 x 30 = 60
60 x pi (3.14) = 188.4 centimeters or 1.884 meters
Changing the kilometers into meters, and diving by 3 (to reduce the 3 hours into meter per hour) you'd get the total distance covered is 36,000 meters which equates to 12,000/hour or 200 meters/minute or 3.33 meters/second.
You take 3.33 and divide it by 1.884 which will give you 1.7675
Now you multiply it by the number of degrees of the wheel (which of course is 360) so 1.7675 x 360 = 636.3
Your answer is 636.3 degrees per second.
Answer:
d
Step-by-step explanation:
Self-interest assumption means that an action taken by a person can be termed as self interest if he or she has any basis or reason behind taking such action. The individual always looks for profit and self benefit.Hence they can be treated as selfish.
So, if a person sacrifices his or her own interest so that others can be punished then such act can be termed as self-interest as person concerned is taking such action with a reason behind such act.
Hence, the correct answer is the option (d).
1. Move the negative sign to the left.
- *-50
2. Use this rule: =
-
3. Simplify -
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
Answer: Third option
Step-by-step explanation:
We have the vector u and the vector v. We must perform the operation .
To perform this operation multiply the vector u by -1 and multiply the vector v by -1.
If u = (-5,6)
So
-1u = (5, -6)
If v = (7, -3)
So
-1v = (-7, 3)
Then the sum of both vectors is done by adding the components of u with the components of v.
Answer:
A. -2, -5
Step-by-step explanation:
x^2 + 7x + 10 = 0
Factor the equation
What 2 numbers multiply to 10 and add to 7
2*5 =10
2+5 = 7
(x+2) (x+5)=0
Using the zero product property
x+2 =0 x+5 =0
x=-2 x = -5
