Think of a real-life situation, different from the situations already described in this activity, where knowing the percent

Illusion [34]

Answer:

Suppose the next case.

You want to buy an object from another state or country, you know that the cost of this object is C, and for bringing it from another place, you need to pay a tax, such that you do not know the exact value of the tax, you know that this can be between 3% and 9%.

Then the tax can be written as:

6% ± 3%

then the error is 3%, this means that the percent error is:

(3%/6%)*100% = 50%

Then you know that there is an error of 50% in the tax.

This can be helpful so you can estimate the maximum and minimum cost of tax that you will pay for this purchase.

Also there are a lot of situations where the percent error give us a lot of information.

"a measure of 10 cm with an error of 1 cm"

The percent error is: (1cm/10cm)*100% = 10%

And in a measure of 3cm with an error of 1cm we have:

(1cm/3cm) = 33.33%

In both cases we have the came error, but different percent error.

Then the percent error also tell us how much the error affects our measure.

Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de l

Setler79 [48]

Answer:

En la primera habitación son usadas 1200 baldosas.

En la segunda habitación son usadas 600 baldosas.

Sobraron 200 baldosas.

Step-by-step explanation:

Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.

Para la primera habitación se han gastado $\frac{3}{5}$ de las baldosas. Esto se expresa como:

$\frac{3}{5}*2000$

Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción $\frac{n}{1}$ . Luego se multiplica los numeradores y denominadores. En este caso:

$\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}$

Para reducir la fraccion, divide 40 entre 10

$\frac{6000}{5} =$ 6000 ÷5= 1200

Entonces en la primera habitación son usadas 1200 baldosas. Por lo que las que quedan se calcula como:

2000 - 1200= 800 baldosas

De esta cantidad de baldosas que quedaron, $\frac{3}{4}$ son usadas para embaldosar la segunda habitación. Esto se expresa como:

$\frac{3}{4}*800$

Resolviendo de igual manera que en el caso de la primer habitación se obtiene:

$\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}$ = 2400 ÷ 4= 600

Entonces en la segunda habitación son usadas 600 baldosas. Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:

800 - 600= 200 baldosas

Sobraron 200 baldosas.

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 13,257 gallons of water, and is leaking at a rat

andre [41]

12,165 gallons
After multiplying 14 and 78 which will equal all the gallons leaked
You will get
1,092
After that just subtract
13,257
With 1,092
Which equals 12,165
