today a boat valued at $45,000.Thebvalue is expected to decrease at a rate of 8.5% each year.What is the value of the boat expec
Stels [109]

Current value of the boat = $45000

Rate at which the value decrease = 8.5%

Value decreased after 1 year = \frac{8.5}{100}\times45000=3825

Hence, value becomes = 45000-3825=41175

Value decreased after 2nd year =

\frac{8.5}{100}\times41175=3499.875

Hence, value becomes = 41175-3499.875=37675.125

Value decreased after 3 year =

\frac{8.5}{100}\times37675.125=3202.385

Hence, value becomes = 37675.125-3202.385=34472.74

So, value of the boat after 3 years becomes $34472.74

£250 in the ratio 4 to 1
Andrej [43]
In the event that you are asking to devide parts, we will use the equation   

·X+X²=Y

We Plug in our parts

·4x+1x=5x(Y)

We then substitute

·4x+1x=250(5x)

Then we devide Y(250) by the number of parts total.

·5 parts total.

·250/5=50

·1 part=50.

Next we substitute.

·200(4)+50(1)=250(5)

-In conclusion your answer is 50£:200<span>£, i hope this is the answer you are looking for, feel free to post your questions here in brainly in the future.</span>
