We know, Q = m.c.Δt
Here, m = 31 g
c= 4.186 J / g C
Δt = 65

Substitute their values, 
Q = 31 * 4.186 * 65
Q = 8434.79 J

In short, Your Answer would be 8434.79 Joules

Hope this helps!

Zinaida [17]

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125
