Answer: 176

Step-by-step explanation:

To evaluate the equation we have to remove the parentheses and add 15 + 17...

1/2 (11)(15 + 17) =

= 11 * 32 * 1/2

Now, we have to turn it into a fraction and multiply it...

\frac{1*11*32 }{2}

= \frac{352}{2}

352 ÷ 2 = 176

I hope this helps!

Answer:

176

Step-by-step explanation:

\frac{1}{2}  \times 11 \times (15 + 17) \\  \frac{1}{2}  \times 11 \times 32 \\  \frac{352}{2}  \\  = 176

hope this helps

brainliest appreciated

good luck! have a nice day!

Which additional facts prove that RST and<br> WXY are congruent? (Geometry)
alexandr402 [8]

Answer:

Option C

Step-by-step explanation:

In the given triangles ΔRSW and ΔWXY,

m(∠S) = m(∠X) = 60° [Given]

Properties of congruence of two triangles applicable in this question,

SAS or ASA

For the congruence of two triangles by the property SAS,

"Two corresponding sides and the included angle should be congruent"

RS ≅ WX, ST ≅ XY and ∠S ≅ ∠X

Which is not given in any option.

For the congruence of two triangles by the property ASA,

"Two consecutive angles and the side having these angles should be congruent"

∠R ≅ ∠W, ∠S ≅ ∠X and RS ≅ XY

Option C will be the correct option.

Can someone explain why A is the right answer to this question? I'm unsure of how to work out this problem.
joja [24]

So firstly, we have to find the radius of the circular garden before finding the circumference (the amount of fencing needed to surround the garden). To find the radius, use the area formula (A=\pi r^2), plug in the area of the garden (36 ft^2) and solve for r as such:

36=\pi r^2\\ \frac{36}{\pi}=r^2\\ \frac{\sqrt{36}}{\sqrt{\pi}}=r\\ \frac{6}{\sqrt{\pi}}=r

So that we know the radius, plug that into the circumference equation (C=2\pi r) to solve:

C=2\pi*\frac{6}{\sqrt{\pi}}\\ C=\frac{12\pi}{\sqrt{\pi}}\\ C=12\sqrt{\pi}

Your answer is A. 12√π.

What does y equal y-16-3y=0
Afina-wow [57]

Answer:

y = - 8

Step-by-step explanation:

y - 16 - 3y = 0

Group like terms

y - 3y - 16 = 0

Add similar elements: y - 3y = - 2y

- 2y - 16 = 0

Add 16 to both sides

- 2y - 16 + 16 = 0 + 16

Simplify

- 2y = 16

Divide both sides by - 2

\frac{-2y}{-2} = \frac{16}{-2}

Simplify \frac{-2y}{-2}: y

\frac{-2y}{-2}

Apply the fraction rule: \frac{-a}{-b}  = \frac{a}{b}

= \frac{2y}{2}

Divide the numbers: \frac{2}{2}  = 1

= y

Simplify \frac{16}{-2}: - 8

\frac{16}{-2}

Apply the fraction rule: \frac{-a}{-b}  = \frac{a}{b}

-\frac{16}{2}

Divide the numbers: \frac{16}{2} = 8

= - 8

y = - 8
