Answer:

x ≈ 21.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin31° = $\frac{opposite}{hypotenuse}$ = $\frac{11}{x}$ ( multiply both sides by x )

x × sin31° = 11 ( divide both sides by sin31° )

x = $\frac{11}{sin31}$ ≈ 21.4 ( to the nearest tenth )

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the

Sergio [31]

Answer:

5.18 pounds per square inch

Complete question:

If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.

Step-by-step explanation:

According to the Gay Lussac's Law:

$\frac{P_1}{T_1} =\frac{P_2}{T_2}$

where, P and T are the pressure and temperature of an enclosed ideal gas.

Given:

Initial pressure $P_1$ = 6 pounds per square inch

Initial Temperature $T_1$ =440° F

Final Temperature $T_2$ =380° F

Final Pressure $P_2$ =?

Substituting all values in the formula

$\frac{6}{440} =\frac{P_2}{380}$

$P_2$ = $\frac{6\times380}{440}$

$P_2$ = 5.18pounds per square inch

Which equations are equivalent to 33/x+ 4 = 12? Check all that apply.

nikitadnepr [17]

Answer:

option c

x + 4 = 64

and

option e

x = 60

Step-by-step explanation:

Given in the question an expression

3∛x+4 = 12

∛x + 4 = 12/3

∛x + 4 = 4

Take cube on both sides of the equation

∛(x + 4)³ = 4³

x + 4 = 64

x = 64 - 4

x = 60

vivado [14]

Answer:printer=120$

computer=390$

Step-by-step explanation:

printer=x

computer=x × 13/4

x+x × 13/4=510

(4x+13x)/4=510

17x=510×4

x=2040÷17

x=120

y=120×13/4

=390
