Answer=C

The conversion formula between Celsius and Fahrenheit is:

°F=(9/5*°C)+32

Based on the information given, we know that °C=30. So we can solve for °F.

°F=(9/5*°C)+32
°F=(9/5*30)+32
°F=(54)+32
°F=86

30 Degrees Celcius is equivalent to 86 degrees Fahrenheit.

If a thermometer indicates 30 degrees Celsius, the temperature in degrees Fahrenheit is 86°F.

Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit.

So, if you want to convert Celsius into Fahrenheit, you will need to:
Multiply by 180/100
Add 32

Let's convert 30 degrees Celsius into Fahrenheit.
30 180/100 = 54
54 + 32 = 86

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>Solution:</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:

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

Last month, she paid $3.20 for 16 international texts

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

When four fifths 4 5 of a number is subtracted from 1414, the result is 22. find the number?

galben [10]

If we say:
x = the number we want to find
Then, we can formulate an equation using the information given:
1414 - 4x/5 = 4
Now, we just solve for x:
4x/5 + 4 = 1414
4x/5 = 1410
4x = 7050
x = 1762.5
