Answer:

Milagros tiene que pintar 78m^{2}.

Milagros debe comprar 2 botes de pintura.

Step-by-step explanation:

La pregunta está incompleta. Faltan datos. Los adjunto :

'' Milagros ha ido a casa y ha medido las paredes, el techo, las puertas y las ventanas del salón. Todo tiene forma rectangular y las dimensiones son las siguientes :

<u>PAREDES</u> :

  • 2 paredes de 6 m de largo y 3 m de alto.
  • 2 paredes de 4 m de largo y 3 m de alto.

<u>TECHO</u> :

  • 6 m de largo y 4 m de ancho.

<u>PUERTA</u> :

  • 1 puerta de 2 m de alto y 1.5 m de ancho.

<u>VENTANAS</u> :

  • 2 ventanas de 1.5 m de alto y 1 m de ancho. ''

Para la primera pregunta vamos a calcular cuantos metros cuadrados tiene que pintar Milagros haciendo lo siguiente :

Vamos a calcular el área de las paredes y del techo y al resultado le vamos a restar el área de la puerta y de las ventanas (dado que consideramos que la puerta y las ventanas no las pintará).

El área de una superficie rectangular se calcula como largo por alto ⇒

Para las paredes tenemos :

2 paredes de 6 m por 3 m y 2 paredes de 4 m por 3 m ⇒

2.(6m).(3m)+2.(4m).(3m)=60m^{2}

Para el techo tenemos :

(6m).(4m)=24m^{2}

Si sumamos el área de las paredes y el techo :

60m^{2}+24m^{2}=84m^{2}

Al área calculada le restaremos el área de la puerta y de las ventanas :

84m^{2} - área de la puerta - área de las ventanas ⇒

84m^{2}-(2m).(1.5m)-(2).(1.5m).(1m)=78m^{2}

78m^{2} es el área de pintar.

Ahora bien, si con 1 kilogramo de pintura puede pintar 8m^{2} ⇒

\frac{78}{8}=9.75 kilogramos

Encontramos que Milagros necesita 9.75 kilogramos de pintura para pintar el salón de su casa.

Si en un bote de pintura hay 5 kilogramos, necesitará de 2 botes de pintura (10 kilogramos en total) para poder pintar su salón

Candy takes 57 minutes to deliver all the paper whereas Tim takes 114 minutes. How long does it take them where they work togeth
kow [346]

-- Candy takes 57 minutes to do the whole job  ==> 
She does 1/57 of the job every minute.

-- Tim takes 114 minute to do the whole job  ==> 
He does 1/114 of the job every minute.

-- If they work together, they do  (1/57  +  1/114)  of the job every minute.
We have to add those fractions.

The least common denominator is 114.

                 (1/57  +  1/114)

             =  (2/114 + 1/114)

             =        3/114       =  1/38 .

Working together, Candy and Tim do  1/38  of the job every minute.

So it takes them  38 minutes  to do the whole job together.

I believe the answer would be angle O.

All you do to find this answer is rotate the 2nd figure so it matches the 1st one above it, and look to see which angles...I guess are where and which match each other.

You can drag in the first empty box ∡3 and get ∡2≅∡3.

In the second box you can drag '' definition of angle bisector ''.

In the third empy box you can drag ∡1 and get ∡1≅∡3.

At last empy box you can drag ''transitive property of congruence''

Good luck!!!

10 free points if you know answer to the question. always loooking to make peoples days better!
ira [324]

What you need to know in order to answer this:

       In math, the symbol " ! " is used to indicate "factorial".
       "Factorial" means the product of the integers from 1
       up to the number.

Examples:

       
2 !  =  "two factorial"  =  1 * 2  =  2

        4 !  =  "four factorial"  =  1 * 2 * 3 * 4  =  24

For this question:

  10 !  =  "ten factorial"  =  1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10

                                       =  3,628,800 .

If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.

And by the way, the points aren't 'free'.  I had to
give you some information in order to earn them.
