Softa [21]

Answer:

57 °C.

Step-by-step explanation:

The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :

C=\dfrac{5}{9}(F-32) ...(1)

If T = 134° F, we need to convert the temperature in Celsius.

Put F = 134, in equation (1)

C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C

So, the temperature on that day is 57 °C.

Evgen [1.6K]

The complete question is;

A paintball court charges an initial entrance fee plus a fixed price per ball.

P represents the total price (in dollars) as a function of the number of balls used n.

P = 0.80n + 5.50

How much do 10 balls cost?

Answer:

Cost of 10 balls = 8 dollars

Step-by-step explanation:

We are told that;

total price in dollars is given as a function of the number of balls

p = 0.8n + 5.5

Where n is number of balls.

We are told that the price above is price of number of balls plus entrance fee.

Thus, 5.5 dollars is the entrance fee while 0.8n dollars is the price for n number of balls.

Thus,for 10 balls,

Price of 10 balls will be 0.8 x 10 = 8 dollars
