Answer:
Step-by-step explanation:
1. Exchange rate = 1 U.S. dollar per 0.9009 foreign currency
i. U.S. Currency (in dollars) = 73.00
Foreign currency = 81.03
ii. U.S. Currency (in dollars) = 20.00
Foreign currency = 22.20
2. Exchange rate = 1 U.S. dollar per 1.3699 foreign currency
i. U.S. Currency (in dollars) = 30.00
Foreign currency = 21.90
ii. U.S. Currency (in dollars) = 50.00
Foreign currency = 36.50
3. Exchange rate = 1 U.S. dollar per 1.5873 foreign currency
i. U.S. Currency (in dollars) = 25.00
Foreign currency = 15.75
4. Exchange rate = 1 U.S. dollar per 1.11 Australian dollar
i. U.S. Currency (in dollars) = 72.00
Equivalent Australian dollar = 72.00 x 1.11 = 79.92
We have 35 - 5 = 30 levels left to beat.
The question is asking us for the levels left to beat, to the ones that already have been beaten:
30 : 5
Simplified;
6 : 1
Answer: 
Step-by-step explanation:
Given
The scale factor of two similar hexagons is 5:12.
The smaller hexagon has an area of 24 square units
we know, the ratio of two similar figures is equal to the square of the scale factor.
Suppose the area of the larger hexagon is A
![\therefore \dfrac{24}{A}=\left[\dfrac{5}{12}\right]^2\\\\\Rightarrow A=\left[\dfrac{12}{5}\right]^2\times 24\\\\\Rightarrow A=138.24\ \text{square units}](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cdfrac%7B24%7D%7BA%7D%3D%5Cleft%5B%5Cdfrac%7B5%7D%7B12%7D%5Cright%5D%5E2%5C%5C%5C%5C%5CRightarrow%20A%3D%5Cleft%5B%5Cdfrac%7B12%7D%7B5%7D%5Cright%5D%5E2%5Ctimes%2024%5C%5C%5C%5C%5CRightarrow%20A%3D138.24%5C%20%5Ctext%7Bsquare%20units%7D)
