A certain appliance uses w watts to run. If you run it for m minutes, and the cost per kilowatt-hour is c, the cost of running the appliance for m minutes is given by the formula (w(m/60))/1000 c. Find the cost of running an appliance that requires 500 watts for 25 minutes at a cost of $0.125 per kWh.

The cost for this appliance is $0.02604

Step-by-step explanation:

In order to solve this problem we need to apply the appliance's values to the provided formula as shown bellow:

cost = {[w*(m/60)]/1000}*c

cost = {[500*(25/60)]/1000}*0.125

cost = {[12500/60]/1000}*0.125

cost = {208.4/1000}*0.125

cost = 0.2084*0.125 = 0.02604

The cost for this appliance is $0.02604

$1.68

Step-by-step explanation:

If the function modelled for finding the cost of running the appliance for m minutes is given by the formula (w(m/60))/1000 c, and the following datas are given:

W = 500watts

m = 25minutes

c = cost per kWhr = $0.125

Cost of running an appliance that requires 500 watts for 25 minutes at a cost of $0.125 per kWh will be gotten by substituting the given data in the modelled function.

C= {500(25/60)}/1000 (0.125)

C =(500×0.42)/125

C = 210/125

C = $1.68

The cost of running the appliance will be $1.68

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
