Answer:
168 in²
Step-by-step explanation:
The square would be 36 in²
Area of a triangle is A= 1/2 bh
A = 1/2 (11 x 6), A= 1/2 (66)
1/2 (66) = 33 in², which is the area of a triangle.
Then you multiply 33 x 4 to get the area of all the triangles, which is 132 in²
You add the area of the square to the area of the triangles, which is 168 in².
1) Well you divide the copies by 14 for the amount of friends that Ivan has helping him then multiply that to the 0.25 cents that he is playing them.
2) You multiply 1428 of the copies of flyers to the 0.10 then add that answer to the answer of number 1
It's an 11% increase. To find this, you have to subtract 85 from 94.35 and then you divide that difference by the original amount. In this case it's 85. After that, you get .11. Then you just turn it into a percent.
Differentiate the function.
