Sue graphed the formula for converting temperatures from Fahrenheit to Celsius. If the temperature is 50 degrees Fahrenheit, wha

KATRIN_1 [288]

Answer:

Second Option (10° Celsius)

Step-by-step explanation:

There is a formula to convert the temperature which is in degree Celsius into degree Fahrenheit and vice versa. The formula to convert the temperature in degree Fahrenheit into degree Celsius is:

C° = (F° - 32) * 5/9.

It is given that the temperature is 50° Fahrenheit. Therefore, F° = 50°. Substituting F° = 50° in the formula gives:

C° = (50° - 32) * 5/9.

Further simplification results in:

C° = 18 * 5/9. Therefore, C° = 10°.

So the correct answer is 10° Celsius!!!

*5 POINTS* plz help i need both of them

yuradex [85]

Answer:

see explanation

Step-by-step explanation:

(a)

(f + g)(x) = f(x) + g(x)

f(x) + g(x) = 6x - 2 + 2x + 4 = 8x + 2

(b)

(f - g)(x) = f(x) - g(x)

f(x) - g(x) = 6x - 2 - (2x + 4) = 6x - 2 - 2x - 4 = 4x - 6

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is

Sloan [31]

Answer:

$x \approx 21.080\,ft$ , $y = 29.080\,ft$

Step-by-step explanation:

The total area of the pool and the walkway is:

$(x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}$

$(x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}$

$x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}$

$x^{2} + 20\cdot x - 866\,ft^{2} = 0$

The roots of the second-order polynomial is:

$x_{1} \approx 21.080\,ft$ and $x_{2} \approx -41.081\,ft$

The only possible root is:

$x \approx 21.080\,ft$

The other dimension of the pool is:

$y = x + 8\,ft$

$y = 21.080\,ft + 8\,ft$

$y = 29.080\,ft$
