Answer:

$3.78

Step-by-step explanation:

Given: The first group bought 6 slices of pizza and 4 soft drinks for $ 28.28.

The second group bought 5 slices of pizza and 4 soft drinks for $ 24.50.

To find: The cost of one slice of pizza.

Solution: Let the cost of one slice of pizza be $ x, and the cost of one soft drink be  $ y.

As per question,

6x+4y=28.28 ...(1)

5x+4y=24.50 ...(2)

On subtracting equation 2 from 1 we have,

x=28.28-24.50

x=3.78

Hence, one slice of pizza costs  $3.78.

When a cold drink is taken from a refrigerator, its temperature is 5°C. After 25 minutes in a 20°C room its temperature has incr
Andrews [41]

Answer:

  (a)  13.85 °C

Step-by-step explanation:

The temperature difference is a decaying exponential function of time. Here, it decreases from an initial difference of 15 °C to 10 °C after 25 minutes. So, that temperature difference can be modeled as ...

  ΔT = 15(10/15)^(t/25)

We want to find the value of this at t=55. It is ...

  ΔT = 15(2/3)^(55/25) ≈ 6.15

This is the amount the temperature of the drink is below room temperature.

  drink temperature = (20 - 6.15) °C = 13.85 °C

The temperature of the drink after 55 minutes is about 13.85 °C.
