Answer:
77.75%
Step-by-step explanation:
We just have to find the sums of the product of Joey's averages and their contribution to the total grade.
Test: 0.45 * 0.8 = 0.36 = 36%
Quizzes: 0.3 * 0.85 = 0.255 = 25.5%
Homework: 0.25 * 0.65 = 0.1625 = 16.25%
Total: 36% + 25.5% + 16.25% = 77.75%
Answer:
Row 1 -
1/3, 1/2, 1/3, 2/3, 2/3, 8/15, 1/2.
Row 2 -
3/4, 3/4, 2/7, 21/25, 5/6, 7/9, 1/3.
Row 3 -

Answer:
42
Step-by-step explanation:
168 factors into
2•2•2•3•7
two of the 2's make a perfect square
(2•2)•2•3•7
2²•2•3•7
as none of the product of the remaining factors makes a perfect square
2•3 = 6, 2•7 = 14, 3•7 = 21
we need to multiply the remaining factors together to find another perfect square
2²•(2•3•7)²
2•3•7 = 42
42(168) = 7056 = 84²
The answer would be $2.70
