Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :
Also,
Where
is the angular speed
So,
Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
Thank you for posting your question here at brainly. The answer to the above question is the first one in the choices which is 15. Below is the solution:
<span>
3x + 10 = 55
Subtract 10 from each side...
3x = 45
Divide by 3...
x = 15</span>

with what lol?
Step-by-step explanation:
Answer:
d in (-oo:+oo)
(5/9)*d = 9/10 // - 9/10
(5/9)*d-(9/10) = 0
(5/9)*d-9/10 = 0
5/9*d-9/10 = 0 // + 9/10
5/9*d = 9/10 // : 5/9
d = 9/10/5/9
d = 81/50
d = 81/50
Step-by-step explanation:
To check which of the quotients is correct, multiply 43 times 20 and add the remainder. The result must be equal to 876.
First, notice that 20 times 43 equals 860.
A)
The remainder is 17. 860 + 17 = 877, which is not equal to 876.
B)
The remainder is 16. 860 + 16 = 876, which is equal to 876.
C)
The remander is 7. 860 + 7 = 867, which is not equal to 876.
D)
The remainder is 6. 860 + 6 = 866, which is not equal to 876.
Since 20*43 + 16 = 876, then the correct quotient is shown in option B:
876 ÷ 43 = 20 r 16
