Answer:

27. C

28. D

Step-by-step explanation:

The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

Solving this equation gives:

$\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105$

So D is the right answer for 28.

The area of the Logo 1 will be 12.48 square meters and the area of the Logo 2 will be 9.6 square meters.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Now consider the logos for Parkside Printing shown.

Determine the actual area of Logo 1 and Logo 2 in square meters will be

The area of the Logo 1 (A₁) will be

$\rm A _1 = 12 \times 8 - 6 \times 3\\\\A_1 = 78 \ cm^2\\\\A_1 = 78 \times 0.16 \ m^2\\\\ A_1 = 12.48 \ m^2$

Then the area of the Logo 2 (A₂) will be

$\rm A_2 = \dfrac{1}{2} \times 12 \times 10\\\\A_2 = 60 \ cm^2\\\\A_2 = 60 \times 0.16 \ m^2\\\\A_2 = 9.6 \ m^2$
