She would have to score atleast a 74 on the test for her average to be 78
Answer:
Yes
Step-by-step explanation:
The sum must be greater than 8 it can't be 7 anyway. Sums can be 9, 10 or 12. P = (4+3+1)/36 = 3/36
Answer: D is correct, 52.9%
Step-by-step explanation:
% decrease from 340 to 160, Where 340 is the old number and 160 is the new number
Percent change = (New number - Old number) / Old number x 100%
Percent change
= (160 - 340) / 340 x 100
= (-180) / 340x 100 = -52.94%
I hope this is clear, please mark as brainliest answer.
By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
