Harman [31]

Answer:

Rain is correct, calculates correctly, 238.5 square inches

Step-by-step explanation:

The given triangular pyramid is shown with the dimensions.

The surface area of the triangular pyramid is given by :

$A=\frac{1}{2}\left(a \times b\right) + 3\left(\frac{1}{2}\times b\times s\right)$

$A=\frac{1}{2}\left(10 \times 8.7\right) + 3\left(\frac{1}{2}\times 10\times 13\right)$

$A=43.5+(3\times 65)$

$A=43.5+195$

$A=238.5 \ \text{inche}^2$

Therefore, the surface area of the triangular pyramid is = 238.5 square inches.

First, add the number of total male and female students.

216 + 207 + 198 + 194 = 815 males

193 + 214 + 197 + 201 = 805 females

Second, add to find the total number of students.

815 + 805 = 1620

Third, create a ratio from females to total students

805/1620

Fourth, simplify the fraction.

805/1620 → 161/324

Therefore, the answer is A.

Best of Luck!
