Answer:

2 inches

Step-by-step explanation:

First, find out how many times 3 feet goes into 24 feet. You should get 8 times. Then, multiply 1/4 times 8, and the answer should be 2. For every 2 inches, on the blueprint, it will be 24 feet in real life. Hopefully this helps!

What is the area of this figure?
KatRina [158]
Hi!

I have attached 2 images that should help you understand :)

First, look at the edits I made to the image you posted. I separated the shape into smaller shapes so that we can find the area of each individual one. 

Let's start with the rectangle.

To find the area of a rectangle, multiply the width times the height. 
10 · 4 = 40

Rectangle = 40cm

Next up, the red triangles.

I have included another image showing the triangles combined into rectangles. So we can find the area of the triangles just like we would rectangles!

(let me know if you don't understand how I found the width + height of the triangles)

5 · 10 = 50

Red triangles = 50cm

And finally, the green triangles.

8 · 7 = 56

Green triangles = 56cm

Add it all together and you get...

40 + 50 + 56 = 146

The answer to the question is 146cm.

Next time you are having trouble with something like this, picture the triangles as rectangles! :)

Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t
Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to \frac{-1}{2}

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle 330^{\circ} is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle =360-angle

As the angle is 330°

So the reference angle will be =360-330=30^{\circ}

Now we have to find the value of

sin(330°) =sin(2\pi -30)=-sin(30)=\frac{-1}{2}

And now cos(330^{\circ})=cos(2\pi -30)=cos30=0.866
