12*$.73=$8.76-$7.68=$1.08 So it is $1.08 cheaper to buy it by the case.

Hope that helps.

Step-by-step explanation:

This problem is incorrect

the square root of 9 is two of the same numbers that are multiplied together to get 9 so $\sqrt{9}$ =3

9+1/2=9.5

Hope that helps :)

According to Charles's law, if the pressure is held constant, the volume of a gas varies directly with the temperature measure

Ksju [112]

Answer:

V₂ = 252 cm³

Step-by-step explanation:

Charles's law = If the pressure is held constant, the volume of a gas varies directly with the temperature measured on the Kelvin scale.

Mathematically, $V=kT$

$\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

We have, V₁ = 192 cm³, T₁ = 112 K, T₂ = 147 cm³, V₂ = ?

Using the above relation of Charles's law :

$V_2=\dfrac{V_1T_2}{T_1}\\\\V_2=\dfrac{192\times 147}{112}\\\\V_2=252\ cm^3$

So, the new temperature is 252 cm³.

NEED HELP QUICK!! :)

Vlada [557]

Let x and y be your two consecutive whole numbers

x < sqrt(142) < y
x^2 < 142 < y

So, we are looking for x and y such that x^2 < 142 and y^2 > 142.

The closest squared number to 142 is 144 = 12^2.
Next is 11^2 = 121.

11 and 12 are consecutive.

11^2 = 121 < 142 < 144 = 12^2

Thus, 11 and 12 are your numbers
