Answer:
Step-by-step explanation:
Given
Call out fee = £35
Per hour = £30
Time = 2 hours
Per light switch = 12 minutes
Required
Cost of wiring a house with 10 light switches
First, the minutes on the 10 light switches should be calculated'
If time per light switch is 12 minutes;
then
Time for 10 = 12 minutes * 10
Time for 10 = 120 minutes
[Convert to hours]
Time for 10 = 2 hours
Next is to calculate the total time spent altogether
Time = 2 hours + Time spent on 10 light switches
Time = 2 hours + Additional 2 hours
Time = 4 hours
Total Charges = Call out fee + Charges per hour * Time
Total Charges = £35 + £30 * 4
Total Charges = £35 + £120
Total Charges = £155
False, it can. I hope this helps

Answer:
13/1*7/4
Step-by-step explanation:
The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.
