Answer:

Step-by-step explanation:

I use the Pythagoras theorem.

$\sqrt{a^{2} +b^{2} } =c^{2}$

$4^{2}{x}6^{2} = c^{2}$

16 x 36= 576

$\sqrt{576} = 24$

A machine makes 600 candies a minute. At this rate, how long will it take this machine to make 1800 boxes, each of which contain

Marta_Voda [28]

1800 boxes with 24 candies each

Total = 1800 * 24 = 43 200 candies

The machine makes 600 candies in 1 minute

   1 candy would take (1/600) minute

   43 200 candies would take 43200 * 1/600 = 72

   = 72 minutes.

Therefore the 1800 boxes would be done in 72 minutes.

Answer:

D) b = $\frac{S-2ac}{2a + 2c}$

Step-by-step explanation:

First, move all the terms that do not include b to the left side with S:

S = 2ab + 2bc + 2ac

S - 2ac = 2ab + 2bc

Now, factor out 2b from the right side:

S - 2ac = 2b(a + c)

Divide both sides by 2(a + c):

b = $\frac{S-2ac}{2(a + c)}$

Finally, multiply out the denominator:

b = $\frac{S-2ac}{2a + 2c}$
