Answer:

AB = 25

Step-by-step explanation:

First things first, we know that these triangles are similar. Now let's find BC using the Pythagorean Theorem. BC = 5\sqrt5, this side is similar to the 5 side of the smaller triangle. That means each side of the larger triangle \sqrt5 times larger than the corresponding side on the small triangle. That means AB is \sqrt5 times larger than BC as well. So multiply BC by \sqrt5 get us the answer.

A compact disc player costs £50 plus 17 1/2% Vat. Calculate the total cost of the compact disc player
Shtirlitz [24]
With Calculator:
To work out the multiplier, take the percentage, divide by 100 and add 1
17.5% / 100 = 0.175
1 + 0.175 = 1.175
£50 x 1.175 = £58.75

Without Calculator:
First work out easy percentages of 50 (if needed use previous answers (such as 10) to work out smaller percentages (such as 5%))
100% = 50
10% = 5
5% = 2.5
2.5% = 1.25
10% + 5% + 2.5% = 17.5%
5 + 2.5 + 1.25 = £8.75
Add this on to the original price:
£50 + £8.75 = £58.75

The total price, including VAT, is £58.75

The answer is D. 60/100

In order to get the denominator from 5 to 100, you must multiple it by 20, meaning you also have to do that to the numerator. 3x20=60, therefore, the answer is 60/100
