Mathematics

Answer:

The smallest share is 10 birds.

Step-by-step explanation:

To find the smallest share, we must find the smallest number in the ratio. We divide this by the sum of the individual numbers in the ratios; and multiply by the amount to be shared.

The calculation is done as follows;

\frac{smallest share}{ total ratio}* quantity to be shared \\   \frac{2}{8 + 5 + 2} * 75 \\  \frac{2}{15}* 75  \\   \frac{150}{15} \\ 10

The rest can be calculated by;

\frac{8}{15}  \times 75 = 40 \\  \frac{5}{15}*75 = 25

As a check, adding the three quantities gives you 75

40 + 25 + 10 = 75

Answer:

10

Step-by-step explanation:

The total parts are:

8 + 5 + 2

= 15

Divide 75 with 15.

= 5

Multiply the ratio with 5.

8×5:5×5:2×5

40:25:10

The smallest share is 10.

Can some one solve this (squar roots) ​
Inessa05 [86]

Answer:

2\sqrt{6}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{96}

= \sqrt{16(6)}

= \sqrt{16} × \sqrt{6} = 4\sqrt{6}

\sqrt{24}

= \sqrt{4(6)}

= \sqrt{4} × \sqrt{6} = 2\sqrt{6}

Thus

\sqrt{96} + 2\sqrt{6} - 2\sqrt{24}

= 4\sqrt{6} + 2\sqrt{6} - 4\sqrt{6} ← collect like terms

= 2\sqrt{6}
