Answer:

125

Step-by-step explanation:

y = 1k/x^3  I am trying to find the constant k.  I will use the information that I have been given to find k

1 = k/5^3

1 = k/125  Multiply both sides by 125

125 = k

Now, we will find y when x = 1

y = 125/1^3

y = 125

Answer:

  $2.59

Step-by-step explanation:

Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...

  b +5m = 16.24

  3b +2m = 15.05

Subtracting the second equation from 3 times the first, we have ...

  3(b +5m) -(3b +2m) = 3(16.24) -(15.05)

  13m = 33.67 . . . . . . simplify

  m = 2.59 . . . . . . . . . divide by 13

The cost of a milkshake is $2.59.

Answer:

a). 59.049°C

b). 2.1179 seconds

Step-by-step explanation:

Expression representing the final temperature after decrease in temperature of the metal from 100°C to T°C is,

T = 100(0.9)^{x}

where x = duration of cooling

a). Temperature when x = 5 seconds

T = 100(0.9)⁵

  = 59.049

  ≈ 59.049°C

b). If the temperature of the metal decreases from 100°C to 80°C

Which means for T = 80°C we have to calculate the duration of cooling 'x' seconds

80 = 100(0.9)^{x}

0.8 = (0.9)^{x}

By taking log on both the sides

log(0.8) =log[(0.9)^{x}]

-0.09691 = x[log(0.9)]

-0.09691 = -0.045757x

x = \frac{0.09691}{0.045757}

x = 2.1179

x ≈ 2.1179 seconds
