Colin buys a car for £15500.
timama [110]

Answer:

£14889.30

Step-by-step explanation:

The cost of the car = £15500.

For the first year,

depreciation = £15500 x 1%

                     = £155

Its worth after the first year = £15500 - £155

                             = £15345

For the 2nd year,

depreciation = £15345 x 1%

                     = £153.45

Its worth after the second year = £15345 - £153.45

                                 = £15191.55

For the 3rd year,

depreciation = £15191.55 x 1%

                      = £151.9155

Its worth after the third year = £15191.55 - £151.9155

                                            = £15039.6345

For the 4th year,

depreciation = £15039.6345 x 1%

                     = £150.3963

Its worth after the fourth year = £15039.6345 - £150.3963

                                             = £14889.2382

Thus, the worth of the car in 4 years would be £14889.30

What is the length of segment AE?
DedPeter [7]
By looking at the bottom length of both triangles, we can determine the scale from one to the other.

C-E = 30 units
D-F = 28 units

This can be translated as the fraction 15/14.

So if we look back at the possible answers, both B and C are likely candidates for being the answer.

But to get the answer, we multiply 24 X (15/14).

Which is 25.7, or 25 and 5/7.  Your answer is C.

7. A battery manufacturer makes batteries that have a failure rate of .015. That is, 15 out of each 1,000 batteries are defectiv
azamat
The answer to this probability question is .86 or 86%. The probability that a batch of 10,000 batteries will contain at least 175 defective batteries is  86 percent. I calculated the failure rate of 10,000 batteries (10k*.015) and yielded 150, meaning there will be 150 batteries that will be defective in a set of 10,000. Then i divided 150 by 175 to get the probability.
