How to convert a repeating decimal to a fraction when only 1 digit is repeating?

1 answer:

5 0

Example 0.777777

x = 0.77
10(x = 0.77) ----(10 because it is repeating by the tenth digit. if repeating by 2 digits like 0.2828, you'll multiply by 100)

10x = 7.77
-(x = 0.77)
9x = 7.00
x = 7/9

The length of one leg of a right triangle is 3 feet more than the other leg. If the hypotenuse is 15 feet find the length of eac

melamori03 [73]

Answer:

Leg1 = 9 and leg2 = 12

Step-by-step explanation:

Points to remember

Pythagorean theorem

Hypotenuse² = Base² + Height²

To find the length of each leg

It is given that, hypotenuse = 15 feet

Let base = x the height = x +3

By using Pythagorean theorem we can write,

Hypotenuse² = Base² + Height²

15² = x² + (x + 3)²

225 = x² + x² + 6x + 9

2x² + 6x + 216 = 0

x² + 3x + 108 = 0

By solving we get x = 9 and x -12

Therefore one leg = 9 and other leg = 9 + 3 = 12
