In order to calculate your semester grade in this class, each of your two marking period grades account for 40% of your grade, while your final exam is worth the other 20%. Suppose you earned an 87 for the 1st marking period, a 74 for the second marking period, and a 90 on the final exam. What will your semester grade end up at (round to the nearest tenth)?

Step-by-step explanation:

0.12

Step-by-step explanation:

Because 12\%12%12, percent means 121212 per hundred, we can write it in equivalent forms.

\begin{aligned} 12\%&=\dfrac{12}{100} &=\dfrac{3}{25} &=0.12 \end{aligned}  

12% =  100

12 =   25

3 =0.12

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
