Answer:
Step-by-step explanation:
X = the number of students in Megan's class
4/7 X = the number of girls in the class (G)
4/7 * 2/3 = the number of girls in the class who participate in sports
4/7 * 2/3 = 8/21 of girls in Megan's class participate in sports
Using the Heron's formula, the area of the triangle is: D. 95 square inches.
<h3>What is the Heron's Formula?</h3>
Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.
Given the following:
s = semi-perimeter = 1/2(50) = 25 in.
a = length of side a = 22 in.
b = length of side b = 13 in.
c = length of side c = 50 - 22 - 13 = 15 in.
Plug in the values
Area = √[25(25 - 22)(25 - 13)(25 - 15)]
Area = √[25(3)(12)(10)]
Area ≈ 95 square inches.
