Answer:

A. How can the equation be used in temperature conversion?

You take the conversion equation C = (5/9) (F - 32) and you replace the F by the value of Fahrenheit degrees...  then solve the calculations to get the degrees in Celsius.

For example, if you have 80°F to convert in °C:

C = (5/9) (80 - 32) = (5/9) (48) = 26.66 °C

B. How can you use the graph to find the body temp in C?

Using the graph will give a very imprecise measure due the scale of the graph.

But you would have to find 98.6 on the axis of X (it represents the °F), then go upwards until you find the line....

Then report that position on the line on the Y-axis (representing the °C) to get your measure.

<u>Answer:</u>

<u>For A:</u> The linear equation is C=\frac{5}{9}F-\frac{32}{9}

<u>For B:</u> The temperature of normal body in degree Celsius is 37° C.

<u>Explanation:</u>

  • <u>For A:</u>

Linear equations are defined as the equations in which the highest power of a variable is '1'. The general equation for a linear equation is:

y=mx+c

where,

y = Y-coordinate

m = slope of the line

x = X - coordinate

c = intercept on y-axis

For the given equation:

C=\frac{5}{9}(F-32)

The linear equation representation for the given equation is:

C=\frac{5}{9}F-\frac{32}{9}

  • <u>For B:</u>

We are given a value of temperature in degree Fahrenheit. To calculate its value in degree Celsius, we use the equation above.

Putting value of F = 98.6 in above equation, we get:

C=(\frac{5}{9}\times 98.6)-\frac{32}{9}\\\\C=37

Hence, the temperature of normal body in degree Celsius is 37° C.

2. Tomás compró una bicicleta en $199.900. Primero, canceló la mitad y el resto en 7 cuotas de igual valor, con un interés total
Papessa [141]

Answer:

Cada cuota tendrá un valor de $14,850.

Step-by-step explanation:

Dado que Tomás canceló la mitad del valor de la bicicleta, la cual costaba $199.900, el valor pagado al inicio fue de $99,950 (199,900 / 2).

Luego, para el valor restante, Tomás suscribió a una financiación con un interés de $4,000, elevando el monto a pagar a $103,950, pagaderos en 7 cuotas. Por lo tanto, dichas cuotas tendrán cada una un valor de $14,850 (103,950 / 7).
