All the choices are correct.

_____
In our base-10 number system, moving a digit one place to the left multiplies its value by 10. Moving it one place to the right multiplies its value by 1/10.

You know already that 1,000 has 10 times the value of 100, and 1/10 the value of 10,000.

Solve to three significant digits 123= 500e ^ -0.12x

Anon25 [30]

$500{ e }^{ -0.12x }=123\\ \\ { e }^{ -\frac { 12 }{ 100 } x }=\frac { 123 }{ 500 } \\ \\ { e }^{ -\frac { 3 }{ 25 } x }=\frac { 123 }{ 500 }$

$\\ \\ { \left( { e }^{ x } \right) }^{ -\frac { 3 }{ 25 } }=\frac { 123 }{ 500 } \\ \\ { e }^{ x }={ \left( \frac { 123 }{ 500 } \right) }^{ \frac { 1 }{ -\frac { 3 }{ 25 } } }$

$\\ \\ { e }^{ x }={ \left( \frac { 123 }{ 500 } \right) }^{ -\frac { 25 }{ 3 } }\\ \\ \ln { \left( { \left( \frac { 123 }{ 500 } \right) }^{ -\frac { 25 }{ 3 } } \right) } =x$

$\\ \\ x=-\frac { 25 }{ 3 } \ln { \left( \frac { 123 }{ 500 } \right) }$

$\therefore \quad x\approx 11.7$

A teapot is

Answer:

If you mean 1/3 and 2/3; The answer is (1/2) teacup = 1 full container.

Step-by-step explanation:

(1/3)t = (2/3)c, the t for teapot and c for the container.

Multiply both sides by (3/2) in order to get 1 on the right-hand side.

(3/2)(1/3)t = (3/2)(2/3)C

(1/2) teacup = 1 full container.
