Answer:
69
Step-by-step explanation:
If she is averaging 65% of the worth of lectures.
the lectures she had was supposedly rated out of 60. Therefore, the 65% will be 65% of 60(total grade)
0.65 * 60 = 39
On the second part, if we apply the same method, we have
0.75 * 40 = 30
All we have to do on add both together
39 + 30 = 69.
therefore, get total grade in the course is 69
Answer:
The value of x in the given figure is, 
Step-by-step explanation:
Complementary angle states that the two angles sum up to 90 degree.
From the given figure
and 
are complementary angles.
by definition of complementary angles;
Subtract from both sides we get;
Simplify:
therefore, the value of x in the given figure is,
Answer:
Step-by-step explanation:
Distribute the brackets.
Add 
on both sides.
Divide 
on both sides.
5Red + 6Blue + 4 Black
Total = 5 + 6 = 4 = 15
Probality of Blue, Blue.
P(Blue) = 6/15 = 2/5
P(Blue, Blue) = (2/5)*(2/5) = 4/25
The next 3 numbers to be highlighted would be 90, 99, and 108.
multiples of 9 is like take 1 times 9 and 2 times 9 and etc.
or you can just keep adding on 9 from the previous number like 81 + 9= 90
