76.475

Step-by-step explanation:

weight(%) ___Grade

Tests 55% 78.5

Homework __25% 80

Th quizzes__15% 72

Participation_5% 50

Overall score = Σ (weight% × grade)

Hence,

(55% * 78.5) + (25% * 80) + ( 15% * 72) + (5% * 50)

43. 175 + 20 + 10.8 + 2.5

= 76.475

Hence, overall score = 76.475

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
