Answer:

24

Step-by-step explanation:

This is just a radical.

3\sqrt{64}.

Radicals are formed by dividing a number into a perfect square, then taking the square root of it and putting it outside the sign.

This means that the value for this will be \sqrt{3^2 \cdot 64}

3^2 = 9\\\\64\cdot 9 = 576

And the square root of 576 is 24 (as 24\cdot 24 = 576).

Hope this helped!

Mariela recolecto 625 mililitros de agua que gotea de su caño en 10 minutos, ella desea saber ¿cuanta agua gastara en una semana
mario62 [17]

Answer:

En una semana gastará 705,6 litros.

Step-by-step explanation:

Con la información proporcionada, puedes calcular cuánta agua gastará por día usando una regla de tres teniendo en cuenta que un día tiene 24 horas y estas equivalen a 1440 minutos. Además, puedes convertir los 700 ml a litros, considerando que 1 litro son 1000 mL, lo que significa que los 700 mL equivalen a 700/1000=0,7 Litros.

 10 min    →  0,7 L

1440 min →       x

x=(1440*0,7)/10

x=100,8 L

Ahora que conoces la cantidad de agua que gastará por día, puedes multiplicar esta cantidad por 7 que es el número de días en una semana:

100,8*7=705,6 L

De acuerdo a esto, la respuesta es que en una semana gastará 705,6 litros.

Each year the seventh graders who study life science participate in a special field trip to the city zoo in 2010 the school paid
juin [17]

Answer:

Yes, the price the school pays each year in entrance fees is proportional to the number of students entering the zoo

Step-by-step explanation:

Relationships between two variables is proportional if their ratios are equivalent.

In 2010, the school paid $1,260 for 84 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1260:84=15:1

In 2011, the school paid $1,050 for 70 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1050:70=15:1

In 2012, the school paid $1,395 for 93 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1,395:93=15:1

As 1260:84=1260:84=1,395:93=15:1,

the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.
