On Naomi's cell phone plan, the amount she pays each month for international text messages is proportional to the number of inte

Lostsunrise [7]

A) The constant of proportionality in this proportional relationship is $k = \frac{y}{x}$

B) The equation to represent this proportional relationship is y = 0.2x

<h3><u>Solution:</u></h3>

Given that,

The amount Naomi pays each month for international text messages is proportional to the number of international texts she sends that month

Therefore,

This is a direct variation proportion

$\text{ amount Naomi pays each month } \propto \text{ number of international texts she sends that month}$

Let "y" be the amount that Naomi pays each month

Let "x" be the number of international texts she sends that month

Therefore,

$y \propto x$

y = kx -------- eqn 1

Where, "k" is the constant of proportionality

Thus the constant of proportionality in this proportional relationship is:

$k = \frac{y}{x}$

<em><u>Last month, she paid $3.20 for 16 international texts</u></em>

Therefore,

y = 3.20

x = 16

Thus from eqn 1,

$3.20 = k \times 16\\\\k = \frac{3.20}{16}\\\\k = 0.2$

Substitute k = 0.2 in eqn 1

y = 0.2x

The equation would then be y = 0.2x

9^6 = x^3 x9^3 solve for x

Nat2105 [25]

Answer:

x = 9

Step-by-step explanation:

${9}^{6} = {x}^{3} \times {9}^{3}$

${9}^{6} = 729 {x}^{3}$

${x}^{3} = \frac{ {9}^{6} }{ {9}^{3} }$

${x}^{3} = {9}^{3}$

${x}^{3} = 729$

$\boxed{\green{x = 9}}$

erma4kov [3.2K]

Answer:

$\frac{2}{3}$ teaspoons of cinnamon per cup of sugar.

Step-by-step explanation:

A recipe calls for $\frac{3}{4}$ cups of sugar for every $\frac{1}{2}$ teaspoons of cinnamon.

For one cup of sugar;

1 × $\frac{1}{2}$ ÷ $\frac{3}{4}$ = $\frac{1}{2}$ × $\frac{4}{3}$ = $\frac{2}{3}$ teaspoons of cinnamon will be needed.
