saul85 [17]2 years ago
3 0

Answer:

option 3- 5 square root 2

Step-by-step explanation:

\sin 45° = \frac{BY}{OY} \\  \\  \frac{1}{ \sqrt{2} }  =  \frac{BY}{10}  \\  \\ BY =  \frac{10}{ \sqrt{2} }  \\  \\ BY =  \frac{10 \times  \sqrt{2} }{ \sqrt{2} \times  \sqrt{2}  }   \\  \\ BY =  \frac{10 \sqrt{2} }{2 }   \\  \\  \huge \red{ \boxed{BY =  5 \sqrt{2} }}

viva [34]

Answer:

hailey played the game longer (1/3 hour).

Step-by-step explanation:

You are deciding which is greater: 1/6 or 1/3.in this case, a smaller denominator (such as 3) produces a greater value.1/3 has a smaller denom. than does 1/6, so 1/3 is greater than 1/6.hailey played the game longer (1/3 hour).

△ABC is a right isosceles triangle, the centers of two arcs are the midpoint of AB
mel-nik [20]

Answer:

  0

Step-by-step explanation:

Let's define 3 areas:

  • S = area of semicircle with radius 6 in (diameter AB)
  • T = area of quarter circle with radius 6√2 in (radius AC)
  • U = area of triangle ABC (side lengths 6√2)

The white space between the "moon" and the triangle has area ...

  white = T - U

Then the area of the "moon" shape is ...

  moon = S -white = S -(T -U) = S -T +U

The area we're asked to find is ...

  moon - triangle = (S -T +U) -U = S -T

__

The formula for the area of a circle of radius r is ...

  A = πr²

So, ...

  S = (1/2)π(6 in)² = 18π in²

and

  T = (1/4)π(6√2 in)² = 18π in²

The difference in areas is S -T = (18π in²) -(18π in²) = 0.

There is no difference between the areas of the "moon" and the triangle.
