By rewriting the weights in decimal form and applying them to the correspondent percentages, we will see that the final grade is 92.8%.
<h3>
What is Jore's final math grade?</h3>
The final grade will be given by:
G = a₁*x₁ + a₂*x₂ + ...
Where the values "a" are the weights, and the values "x" are the averages of Jeorge.
We know that the weights are:
- 30% on Quizzes.
- 10% on homework
- 40% on unit test.
- 20% on the final exam.
Then we can write the weights in decimal form:
a₁ = 0.3
a₂ = 0.1
a₃ = 0.4
a₄ = 0.2
And the scores are:
- 92% on quizzes.
- 98% on homework
- 91% on unit tests
- 95% on final exam.
So the final math grade will be:
G = 0.3*92 + 0.1*98 + 0.4*91 + 0.2*95 = 92.8%

A quadtriatel is said to contain perpendicular diagnols if four go 90 degree angles are formed at the intersection of these lines
One possible way:
-86+(4*12)=-38
-86 is the number where the diver is. 86 feet below the surface.
4*12 is the total number of feet he has ascended in 12 minutes.
Because he is ascending, so you add 4*12 (or 48) to -86.
The answer is -38, meaning he's 38 feet below the surface.
The diver is now 38 feet below the surface.
Hope this helps.
