Answer:
35 degrees
Step-by-step explanation:
2x+13+10x=145
2x+10x+13=145
12x+13=145
12x=145-13
12x=132
X=11
2×+13
(2×11)+13
22+13=35
Answer:
or 0.25 or 25%. Answer as instructed in the question.
Step-by-step explanation:
There are four equal parts and since the spinner is unbiased, the probabilities will be equal.
Answer:
8 m/s^2
Step-by-step explanation:
You can use the equation a = v^2 / r
That is acceleration is equal to velocity squared divided by the radius which in this problem is the length of the string. The velocity is 4m/s and the r the radius is 2 m. Now you can square 4 m/s to get 16 m^2/s^2 THEN you divide by 2 m and the m^2 turns to just m and the 16 to an 8. So, that leaves you with acceleration or in this case centripetal acceleration equals 8 m/s^2.
a = 8 m/s^2 or 8 meters per second squared.
Answer:
just add them and leave it as a positive
