So 60% = 3/5
All you do is 3/5 x 10 = 30/5 and get 6
Answer:
b = 8√3 mm, a = 16 mm, x = 5 ft, y = 5√2 ft.
Step-by-step explanation:
With 30° 60° 90° triangles, one side will be a number, the other leg will be that number multiplied by √3, and the hypotenuse will be 2 times that original number.
So in this case:
The original leg's length is 8 mm. Side b will be that 8 times √3.
So, b = 8√3 mm.
Side a will be 8 times 2.
So, a = 16 mm.
With 45° 45° 90° triangles, the two legs will be the same length, and the hypotenuse will be that number times √2.
So in this case:
The original leg's length is 5 ft. Side x will be that same length.
So, x = 5 ft.
Side y will be 5 times √2.
So, y = 5√2 ft.
If Kim's age is x then Sam's age is 3*x -2 years.
There's an infinite number of equivalent ratios for 27:15, these are the ones that just came to my mind:
27:15 = 54:30 (because 27 * 2 = 54 and 15 * 2 = 30)
27:15 = 9:5 (because 27 / 3 = 9 and 15 / 3 = 5)
27:15 = 135:75 (because 27 * 5 = 135 and 15 * 5 = 75)
