Answer:
1020 raisins
Step-by-step explanation:
Let's set up a proportion using the following setup:
raisins/bags= raisins/ bags
We know there are 680 raisins in 8 bags.
680 raisins/8 bags= raisins/bags
We don't know how many raisins are in 12 bags, so we can say x raisins are in 12 bags.
680 raisins/ 8 bags= x raisins / 12 bags
680/8=x/12
We want to find x. To do this, we must get x by itself.
x is being diveded by 12. The inverse of division is multiplication. Multiply both sides of the equation by 12.
12*(680/8)= (x/12)*12
12*680/8=x
12*85=x
1020=x
x= 1020 raisins
There are 1020 raisins in 12 bags.

The answer is: A - f(x) = 1/2 cos (x)
Assuming the vertex of the triangle shown is the center of the pentagon, and the line segment shown is an altitude of the triangle:
If we join the center of (the circumscribed circle and of) the pentagon to the 5 vertices, 5 isosceles triangles are formed, all congruent to the one shown in the figure. It is clear that these triangles are congruent, so to find the area of the pentagon, we find the area of one of these triangles and multiply by 5.
The base of the triangle is 22.3 in, and the height is 15.4 ins, thus the area of the pentagon is:
5(Area triangle)=5*[(22.3*15.4)/2]=<span>858.55 (square inches).
Answer: </span>858.55 (square inches).
