Test Grades: 60, 68

If the teacher weights homework at 10%, Quizzes at 20%, Tests at 60%, what is her current class average? Please be careful with this one the categories don’t sum to 100% because she hasn’t taken her final exam yet.

Question 5 options:

a) 81

b) 76

c) 69

d) 72

C

Step-by-step explanation:

First we need to find the average in every section, such as the Hw, quiz and tests.

(76+82+85)/3=81 Hw

(74+80+80)/3=78 quiz

(60+68)/2=64 test

Hw is weighted at 10% so it is 81×1=81.

Quizzes are weighted at 20% so 78×2=156

Tests are weighted at 60% so 64×6=384.

Add them all up then divide them by 9,

(81+156+384)/9= 69%

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
