Does anyone know this answer

Ivan

$\frac{1}{a} = \frac{1}{b} + \frac{1}{c} \\ \\ \frac{1}{12} = \frac{1}{b} + \frac{1}{22} \\ \\ \frac{1}{b} = \frac{1}{12} - \frac{1}{22} \\ \\ \frac{1}{b} = \frac{11}{132} - \frac{6}{132} \\ \\ \frac{1}{b} = \frac{11 - 6}{132} \\ \\ \frac{1}{b} = \frac{5}{132} \\ \\ 5b = 132 \\ \\ b = \frac{132}{5} \\ \\ b = 26.4 \\ \\ b = 26$

I hope I helped you^_^

At a school concert,the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others.

Kazeer [188]

Answer: 59.5 minutes.

Step-by-step explanation:

1. You have the following information given in the problem above:

- 8 songs are 4.25 minutes long.

- 3 songs are twice as long as each of the others.

2. Therefore, the total time of 8 songs is:

$(8)(4.25min)=34min$

3. And the total time of the 3 songs is:

$(2)(3)(4.25min)=25.5min$

4. Therefore, you have that the result is:

$34min+25.5min=59.5min$

Please help me find the angle

34kurt

Answer:

79 degrees

Step-by-step explanation:

This is because <CBF is equivalent to <GFI

So, we know two angles in that triangle; 55 and 46.

By adding these together we get 101. In a triangle, the angles all add up to 180.

So we must subtract 101 from 180 and we will have that remaining angle.
