Hello!
Here we have $21.28 total spent and paid for with $30. So 30-21.28= $8.72 so our change must equal this amount. The only choice then would be A.
Hope this helps. Any questions please ask. Thank you kindly.
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 5 revolutions per minute. 1 minute = (1/60) hour.
= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14
= 600*3.14 = 1884 radians / hour
but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile
Linear velocity, v = ωr
v = 1884 radians / hour * (10/5280) mile
v ≈ 3.568 miles / hour
Dividend is the answer which is the first one
Answer:
OPTION D
Step-by-step explanation:
It is given that the current in the circuit is given by V divided by the sum of t and T.
Denoting this mathematically we would have:
Now to solve for T rewrite the above expression.
⇒ T = - t
Therefore the answer would be Option D.
Answer:
12.5%
Step-by-step explanation:
[First Value – Second Value] ÷ [(First Value + Second Value) ÷ 2] × 100
[50 - 30] ÷ [ 50 + 30] ÷ 2 × 100
20 ÷ 80 ÷ 2 × 100
0.25 ÷ 2 × 100
0.125 × 100
