Answer:

\sin(47)  =  \frac{y}{5}  \\ 0.7  \times 5 = y \\ y = 3.5

{5}^{2}  =  {3.5}^{2}  + y {}^{2}  \\  \\  {x }^{2}  = 25 - 12.25 \\ 12.75 \\  = 3.5

Gnesinka [82]

Answer:

17 / 18

Step-by-step explanation:

1/9 + 5/6 needs to be converted to a different equivalent fraction so that the denominators are the same, so;

1/9 = 2/18 and 5/6 = 15/18

2/18 + 15/18 = 17/18!

A certain bacterial culture is multiplying in a culture dish, doubling in size every 6 minutes. It takes exactly an hour to fill
Furkat [3]
Doubling in size,

if the whole dish is filled in an hour (all of it)
how long does it take to fill 1/2 dish?

notice that
1/2 doubled=1/2 times 2=2/2=1 whole dish
therefor it only doubled one more time from the 1/2 point

1hour=all
1hour-6mins=1/2 dish

1hour-6mins=60-6=54 minutes


answer is 54 minutes
