Break the shape up into parts. I break it up into a right triangle at the top, a rectangle in the middle, a tiny rectangle on the left, and a medium rectangle on the bottom.

Area of triangle: 17*5/2=42.5 mi

Can you do the rest?

You are very welcome!

A full circle is 2pi radians. 1.25 pi radians goes 5/8 around the circle.

I think you can solve from there - just find the area of the circle and multiply by 5/8.

You are very welcome!

There is no specific value since the circle can change

10 grams

Answer: 12 (metres)

Explanation:

Let the length be a. Then the width is a-7.

Now, the perimeter is 2(a-7)+2(a)=4a-14, which is 34.

a=12 meters.

You are very welcome!

D: 100.

This happens if 40 is the common angle.

Just saying, I know this is from sparks academy cuz I'm in that same class

Answer to #3: 1,260

Explanation:

Since order doesn't matter, we can use the choose function.

2 are yellow, 3 are green, and 4 are blue.

\({9 \choose 2}=36\), since we are choosing 2 yellow out of 9 total.

Then \({7 \choose 3}=35\), 3 green out of 7 remaining.

4 out of 4 blue is 1.

36*35=1260.

You are very welcome!

(Can someone double check? Thanks)
