D. f(x)= x*-9x^o+2x^2-4x+10
Hi there.
To start, we have to understand where the ten the place is.
Hint: it's 1 place behind the decimal point.
Now we need to know what numbers behind the tenths place make it round up or down.
If the number behind it is 4 or under, round down.
5 & up, round up.
In this case, 830.248 has 2 numbers behind the decimal, so we have to round those THEN the 2 in the tenths place.
830.25 to 830.3
Your answer is D. 830.3
I know this was lengthy, sorry. Just wanted to explain :p
Answer:69.15
Step-by-step explanation: the deviation is 6 which and 1/6 of people got the same grade as him - 100 = 69.15
(h-3k)/2k=-3/4
h-3k=-6k/4
4h-12k=-6k
-12k=-6k-4h
-6k=-4h
Solution: k=2/3h
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
Answer:
7/11
Step-by-step explanation:
Let d represent the original denominator. Then the original numerator is ...
2d-15
The new numerator is ...
(2d-15) +5
and the new denominator is ...
d+7
The ratio of these is 2/3, so we have ...
The original fraction is 7/11.
