How many eighth-size parts do you need to model 3/4? explain

1 answer:

8 0

<span>The way I understand this question is: "how many of one eights (1/8) can fit into 3/4 - so mathematically we would write: 3/4 divided by 1/8. Dividing by a fraction is multiplying by its inverse, so we have 3/4 multiplied by 8, which is 3*8/4, we simplify by dividing 8 and 4 by 4: 6/1, that is 6 - the answer is 6!Hope this helps. Let me know if you need additional help!</span><span />

The logarithm of a quotient can be written as a difference of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3(u) - \log_3(v)$

You can also think of this as a combination of the product-to-sum and reciprocal/power properties of logarithms:

$\log_3\left(\dfrac uv\right) = \log_3\left(u \times \dfrac1v\right) = \log_3(u) + \log_3\left(\dfrac1v\right) = \log_3(u) - \log_3(v)$

To summarize,

$\log_b(mn) = \log_b(m)+\log_b(n)$

$\log_b\left(\dfrac mn\right) = \log_b(m) - \log_b(n)$

$\log_b\left(m^n\right) = n \log_b(m)$

Taya2010 [7]

Answer:

5 cm.

Step-by-step explanation:

Let the lengths of the other 2 sides be 13-1 = 12 and x cm.

Then by Pythagoras:

13^2 = 12^2 + x^2

x^2 = 13^2 - 12^2

x^2 = 169 - 144 = 25

x = √25

x = 5 cm.
