Answer:
2/5
Step-by-step explanation:
To get the ratio as a pure number, it must be expressed as the quotient of two values that have the same units. For the purpose here, it is convenient to convert both values to units of seconds.
__
<h3>units conversion</h3>
The conversion factor between minutes and seconds is ...
1 minute = 60 seconds
Multiplying this equation by 3 gives ...
3 minutes = 180 seconds
__
<h3>ratio of interest</h3>
Then the desired ratio is ...
(72 seconds)/(3 minutes) = (72 seconds)/(180 seconds) = 72/180
= (36×2)/(36×5)
= 2/5
The ratio in its simplest form is 2/5.
For the answer to the question above, the probability that Eduardo pulls out a girl the first time is 16/26 (26 - 10 = 16) which means that pulling out a girl a second time would be 15/25. To find out the probability of both, you have to multiply the fractions together. So (16 × 15)/(25 × 26) which is 240/650. You can simplify this to 24/65, and I believe that is the furthest you can simplify it, which means that the answer is 24/65, I hope this helps!

Answer:
Step-by-step explanation:
Add 9 to both sides of the equation, and divide by the coefficient of B.
T = BA -9
T +9 = BA
(T +9)/A = B
We can rewrite that with B on the left:
B = (T +9)/A
