Answer:
The answer to your question is: Japan
Step-by-step explanation:
Mobile cost in Spain = € 352.5
Mobile cost in Japan = ¥39856
Exchange rate = £1 = €1.41
£1 = ¥188
Cost of mobile in pounds
£ 1 ------------------ € 1.41
x ----------------- €352.5
x = (352.5 x 1) / 1.41
x= £250
£1 ------------------ ¥188
x ----------------- -¥ 39856
x = (39856 x 1) / 188
x = £212
Then, it was cheaper in Japan
Answer:
Hence after period of 9 years from 1990 t0 1999 will be 61438 rabbits.
Step-by-step explanation:
Given:
Population for rabbit obeys exponential law.
120 at 1990 and 240 1991 ...after 1 year time period
To Find:
After 9 year time period how many rabbits will be there.
Solution:
Exponential law goes on present value and various value and time period and defined as ,
let Y be present value Y0 previous year value and k exponential constant and t be time period.
So
Y=Y0e^(kt)
Here Y=240 ,Y0=120 t=1 year time period
So
240=120e^(k*1)
240/120=e^k
2=e^k
Now taking log on both side, [natural log]
ln(2)=ln(e^k)
ln(2)=kln(e)
k=ln(2)
k=0.6931
For t=9 year of time period
Y0=120, t=9 ,k=0.6931
Y=Y0e^(k*t)
Y=120*e^(0.6931*9)
=120e^6.2383
=61438.48
=61438 rabbits
Answer:
The answer is -2
Step-by-step explanation:
you subtract common numbers, so:
5s - 3s = 2s
Then,
-6 + 2 = -4
You would then get
2s - 4
divide -4 by 2 which is -2
and your answer is s = -2
Answer:
3,000
Step-by-step explanation:
Create 2 expressions to represent the cost and the revenue, where x is the number of newspapers:
2x + 15,000 will represent the cost
5x + 6,000 will represent the revenue
Set the expressions equal to each other and solve for x:
2x + 15,000 = 5x + 6,000
15,000 = 3x + 6,000
9,000 = 3x
3,000 = x
So, 3,000 newspaper copies have to be sold to break even
