So simple... 3\ll=27\100 which equals 27.0 or 0.27
The initial amount of the money is £11,000 and the interest is 3.9% per year for first 3 years and then 4.5% after that. If Dan invests it for 7 years, that means the interest would be 3 years of 3.9% and 4 years of 4.5%.
The calculation would be:
total money= initial amount * interestrate1 * interest 2
total money= £11000 *(100%+3.9%)^3<span>*(100%+4.5%)^4
</span>total money= £11000 *(103.9%)^3 * (104.5%)^4
total money= £11000 * <span>1.121622319 </span>* 1.1925186
total money= £14,713.11
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.
√1² + -7² = d
d = 7.1
Cos theta = 75/115
theta = cos^-1 (75/115)
theta = 49.2 degrees
Arc length = Ф/360 * 2πr
= 30/360 * 2*3.14*10
= 1/12 * 62.8
= 5.23
In short, Your Answer would be 5.23 cm
Hope this helps!
