Step-by-step explanation:
The final grade is the average of the two semesters.
70 = ½ (60 + x)
x = 80
So Catherine needs a Semester 2 grade of 80%.
The average of RC3 and RC4 is ½ (62 + 53) = 57.5. This accounts for 90% of the Semester 2 grade. The other 10% is the Spring final.
80 = 0.90 (57.5) + 0.10 (x)
x = 282.5
Catherine would have to score 282.5% on the Spring final in order to pass.
Answer:
9.777777778
Step-by-step explanation:
7/9 written as a decimal is 0.777777778 when we add this on to the whole number 9, we get 9.777777778.

X 307/ty;sm thats is mathematical thingy
F(x) = -3(x + 2)(x - 5)^3 > 0
(x + 2)(x - 5) > 0
x + 2 > 0 or x - 5 < 0
x > -2 or x < 5
-2 < x < 5
Therefore, the stated interval is false.
They are vertical angles and here’s why.
Vertical angles are a pair of opposite angles formed by intersecting lines.
Supplementary angles are two angles that equal 180 when added together.
Adjacent angles are two angles that have a common side and a common vertex.
Complementary angles are two angles that add up to 90 degrees.
Hope this helped!
