Annie invests £9500 for 5 years in a savings account. She gets 1.8% per annum compound interest. How much money does Annie have

Trava [24]

Answer:

£10386.34

Step-by-step explanation:

The amount in an account for a principal P saved at compound interest for a period of n years at an annual rate of r% is calculated using the formula:

$A(n)=P(1+r)^n$

In this case:

Principal, P=£9500

r=1.8%=0.018

n=5 years

Therefore:

$A(5)=9500(1+0.018)^5\\=9500(1.018)^5\\=\£10386.34$

At the end of 5 years, Annie will have £10386.34

Determine whether the triangles in each pair are similar.

DerKrebs [107]

Answer:

None, they are not similar.

You can tell by trying to match ratios with others.

55:42:36

(I put them least to greatest order because triangles cannot really like change only one sides' value, so it makes it visually easier to comprehend.

8:7:5

I can't see any possible way to relate these two ratios together.

The 5 cannot go into 36 anyhow, and like the 8 and 55. The 7 can be multiplied by 6 to get 42, but 5 and 8 cannot reach their own numbers.

Step-by-step explanation:

I shall accept every question from your profile >:)
