Answer:
Weighted mean grade: 81.2
Letter grade: B
Step-by-step explanation:
5 regular tests:
(63+91+88+84+79) / 5 * 60%
= 405 / 5 * 0.6
= 48.6
Final exam:
86 * 10% = 8.6
Project:
90 * 15% = 13.5
Homework:
70 * 15% = 10.5
So her weighted mean grade is
48.6 + 8.6 + 13.5 + 10.5 = 81.2
12.8 is the answer to this problem
Given:
The graph of triangle PQR and triangle P'Q'R'.
To find:
The transformation that will map the triangle PQR onto P'Q'R'.
Solution:
From the given graph it is clear that the triangle PQR is formed in II quadrant and its base lies on the negative direction of x-axis.
The triangle P'Q'R' is formed in IV quadrant and its base lies on the positive direction of x-axis.
This is possible it the figure is rotated 180 degrees about the origin.
Therefore, the correct option is A.
The first decimal point is tenth. 4.88
when rounding, we just look at the number right after the number you want to round to. it's 8 right? since 8 is closer to 10 than 0,
we round it to 4.9
(4.8 + 0.10)
Answer:
Hope this step-by-step helps:
Step-by-step explanation:
In a two-variable problem rewrite the equations so that when the equations are added, one of the variables is eliminated, and then solve for the remaining variable. Step 1: Multiply equation (1) by -5 and add it to equation (2) to form equation (3) with just one variable.
