Answer:

A = 3.14 yd^2

Step-by-step explanation:

The circumference  is given by

C = 2 * pi * r

Letting pi be approximated by 3.14

6.28 = 2 * (3.14) *r

6.28 = 6.28 r

Divide each side by 6.28

6.28/6.28 = 6.28r/6.28

1=r

We can find the area by

A = pi r^2

A = 3.14 (1)^2

A = 3.14

The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m
amm1812

Answer:

%82.5

Step-by-step explanation:

  1. The final exam of a particular class makes up 40% of the final grade
  2. Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

FG=0.40*FE+0.60*0.45,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

\frac{ FG-0.60*0.45}{0.40}=FE.

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825

That is, he need al least %82.5 to obtain a passing grade.
