Answer:
5 years
Step-by-step explanation:
We are given;
- Initial value of the car = $12,500
- Rate of Depreciation = 13% per year
- New value (after depreciation) = $6,250 (half the initial value)
We are required to determine the time taken for the value of the car to depreciate to half the original value.
- We need to know the depreciation formula;
- New value = Initial value ( 1 - r/100)^n
Therefore;
$6,250 = $12,500(1 - r/100)^n
0.5 = (1 - 13/100)^n
0.5 = 0.87^n
Introducing log on both sides;
log 0.5 = n log 0.87
Therefore;
n = log 0.5 ÷ log 0.87
= 4.977
= 5 years
Therefore, it takes 5 years for the value of the car to depreciate to half the initial value.
Answer:
100
Step-by-step explanation:
There are two washers to do linen washing.
We can fit only 5 sets of linens in one washer, and 45 mins are required to wash the linens.
Therefore, within 45 mins we can wash (5×2) =10 sets of lines.
If the shift is of 8 hours i.e. ( 8×60) =480 mins, then within this time the number of linen sets will be washed is (480/45)×10 = 106.67 ≈100 (Answer)
{Since the number of linen set to be washed will be multiple of 10}

Hi
312 bolts ⇒ 30 min
260 bolts ⇒ x min
312x = 30·(260)
312x = 7800
x = 7800/312
x = 25 min
Answer: 25 minutes
