−13π/5 find the reference angle
miss Akunina [59]
I would convert to degrees first seems to make it easier.
\frac{-13 \pi }{5}×\frac{180}{ \pi }
= -468
by adding 360 twice we get the coterminal angle 252

252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72 

If necessary convert back to radians... 72( \frac{ \pi }{180} )= \frac{2 \pi }{5}

Ann [662]

Answer:

The estimate volume of the box holding the tissue boxes V;

V = nv = 9×125

V = 1125 cubic inches

Attached is an image for further understanding of the question;

Step-by-step explanation:

Given;

Volume of each tissue box v = 125 cubic inches

Number of tissues n from the attached image;

n = 3×3 = 9 tissue boxes

The estimate volume of the box holding the tissue boxes V;

V = nv = 9×125

V = 1125 cubic inches

Find the value of each variable<br> x = <br> y=
Karolina [17]

Answer:

x=9

y=9\sqrt{2}

Step-by-step explanation:

This is a special type of triangle known as a 45-45-90 triangle.

The ratio for the sides of this triangle are x:x:x\sqrt{2}

Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.

The hypotenuse, however, is the value of one side multiplied by \sqrt{2}.

In this case it is 9, so 9*\sqrt{2} = 9\sqrt{2}

What is the solution to the system of equations? -2x + y = -5 3x – 2y = 12 A) (3, 1) B) (6, 3) C) (-2, -9) D) (-2, -1)
max2010maxim [7]

Answer:

The correct answer is D) (-2, -1)

Step-by-step explanation:

In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.

-4x + 2y = -10

3x - 2y = 12

---------------------

-x = 2

x = -2

Now that we have the value for x, we can find y by plugging the x value into either equation.

-2x + y = -5

-2(2) + y = -5

-4 + y = -5

y = -1

How does 1/8 divided by 1/4 equal 1/2?
photoshop1234 [79]
When you divide a fraction by a fraction, you're really just multiplying by a reciprocal. A reciprocal is the fraction flipped around.
So, 1/8 <span>÷ 1/4 is the same thing as 1/8 x 4/1
Now, you just multiply. 1 times 4 is 4. 8 times 1 is 8.
1/8 x 4/1=4/8
4/8 simplified is 1/2
So that is how 1/8</span><span>÷1/4=1/2</span>
