How would the following problem be represented using colored tiles? -7 + (-3) seven red tiles plus three blue tiles seven red ti

Lelechka [254]

Answer:

Ok, we have the equation:

-7 + (-3)

Both numbers are negative, so the solution of this will be:

-7 + (-3) = -7 - 3 = -10.

Now, how we can represent it with tiles?

First we need to define, which tiles are the ones representing negative numbers?

We can use:

Red = positive

Blue = negative.

Then:

-7 is represented with seven blue tiles

-3 is represented with tree blue tiles

then:

(-7) + (-3)

will be represented with seven blue tiles, plus tree blue tiles.

When we add them, we have a total of 10 blue tiles, and as blue tiles represent negative numbers, 10 blue tiles is equal to -10.

The percent error is 6.25%

Step-by-step explanation:

Percent error is given by:

$Percent\ Error=\frac{|Experimental\ Value -\ Accepted\ value|}{Accepted\ value}*100$

Here,

Accepted value = 80.0°C

Experimental Value = 75.0°C

Putting the values in the formula

$Percent\ Error=\frac{|80.0 -75.0}{80.0}*100\\=\frac{|5.0|}{80.0}*100\\=\frac{5.0}{80.0}*100\\=0.0625*100\\=6.25\%$

Hence,

The percent error is 6.25%
