Answer:
16.58 feet
Step-by-step explanation:
a² + b² = c²
Think of this as a right triangle
The hypotenuse is 30, and one of the legs is 25
To find the other leg, subtract the square of the hypotenuse by the square of the given leg
30² - 25² = leg
900 - 625 = 275
Square root the answer to find the length of the missing leg
√275 = 16.583123951777
The leg is 16.58 ft.

Answer:
27.5
Step-by-step explanation:
x⠀⠀⠀⠀⠀|⠀⠀⠀⠀200⠀⠀⠀⠀|⠀⠀⠀⠀500
y⠀⠀⠀⠀⠀|⠀⠀ ⠀⠀ 11⠀⠀⠀⠀⠀|⠀⠀⠀⠀a
As x directly varies with y:
200 × a = 500 × 11
a = 5/2 × 11 = 27.5
W={a, b, c, d}
n(W) =4
No of subsets =2^n=2^4=16
The subsets are
{a, b};
{a, c};
{a, d};
{b, c};
{b, d};
{c, d};
{a};
{b};
{c};
{d};
{a, b, c};
{a, b, d};
{a, c, d};
{b, c, d},
{a, b, c, d};
