A. yd^2
This is because you would do 4yd * 3yd which is 12yd^2.
A rug is a flat object in this sense so you would only square it. A 3 dimensional object like a cube would be cubed or to the power of 3.

What is the average score of runa 140,96 and 13?​
scoundrel [369]

\huge\textsf{Hey there!}

\large\textsf{Formula:}

\mathsf{\dfrac{Sum\ of\ all\ terms}{Total\ number\ of\ values\ in\ the\ data}= your\ mean/average}

\mathsf{\dfrac{140+96+13}{3}}

\mathsf{140+36+13}

\mathsf{140 + 96 = \bf 236}

\mathsf{236 + 13}

\mathsf{ = \bf 249}

\mathsf{\dfrac{249}{3}}

\mathsf{= \bf 83}

\boxed{\boxed{\large\textsf{Possible answer: \huge \bf 83}}}\huge\checkmark

Find the values of x and y. Pls helpI’m helpless at math
Svetradugi [14.3K]

Answer:

  • x = 1
  • y=\frac{\sqrt{3}}{2}  

Step-by-step explanation:

From the given right-angle triangle

The angle = ∠60°

  • The adjacent to the angle ∠60° is 1/2.
  • The opposite to the angle ∠60° is y.

The hypotenuse = x

<u>Determining the value of x:</u>

Using the trigonometric ratio

cos 60° = adjacent / hypotenuse

substituting adjacent = 1/2 and hypotenuse = x

cos\:60^{\circ }=\:\:\frac{\frac{1}{2}}{x}

\cos \left(60^{\circ \:}\right)=\frac{1}{2x}

\frac{1}{2}=\frac{1}{2x}          ∵ cos (60°) = 1/2

2x=2

Dividing both sides by 2

\frac{2x}{2}=\frac{2}{2}

Simplify

x=1

Thus, the value of hypotenuse x is:

x = 1

<u>Determining the value of y:</u>

Using the trigonometric ratio

sin 60° = opposite / hypotenuse

As we have already determined the value of hypotenuse x = 1

substituting opposite = y and hypotenuse = 1

sin 60° = y/1

y = 1 × sin 60°

y=\frac{\sqrt{3}}{2}       ∵  \sin \left(60^{\circ \:}\right)=\frac{\sqrt{3}}{2}

Therefore, the value of y is:

y=\frac{\sqrt{3}}{2}      

Summary:

  • x = 1
  • y=\frac{\sqrt{3}}{2}
