Answer:
D) 72
Step-by-step explanation:
The way to find the area of this figure easily is to break it down in regular shapes we know. You can then see it as two horizontal rectangles on top and bottom, measuring 6 x 4 each, then a vertical rectangle in the middle measuring 4 x 6.
So, overall, we have 3 similar rectangles measuring 4x6 or 6x4... which are equivalent.
The area of each of those 3 rectangles is 24 units (6x4).
Since we have 3 of those: 3 * 24 = 72.
Answer:
(x-4)^2 + (y-2)^2 = 3^2
or
(x-4)^2 + (y-2)^2 = 9 (simplified if needed)
Step-by-step explanation:
-Equation of a circle is:
where the center is (h, k) and the radius is 
.
-Place the center and the point onto that equation:
-Then, you solve:
-So, the result is:
or
(simplified if needed)
7.50*4=30
40*4=160
160-30=130
130\4=32.5
so each boy has left 32.5 with him
Here is my friendly solution i'll skip the proof part for now. I am working on the others.
