Answer:
3 and 1 over 3.
Step-by-step explanation:
We divide 5/6 by 1/4.
5 /6 / 1/4
= 5/6 * 4
= 20/6
= 3 2/6
= 3 1/3.
Answer:
x=67.5
Step-by-step explanation:
A full circle is 360°, and the right angle is 90°. The rest of the angle is 270°, or 4x (from 3x+x).
4x = 270
<u>x=67.5</u>
(5, -2) because y=(x-5)^2-2 is really y=x^2-10x+23 after you foil then take the derivative which is y'=2x-10 solve for x and you get 5 then put 5 in the original equation and you get -2 so the answer is (5, -2)<span />
Answer: The number of points added for r right answers is 12r. The number of points taken away for w wrong answers is 4w, so Olga's total points will be
... 12r -4w
To win, she needs this number to be more than 400. Your inequality is ...
... 12r -4w > 400
Assuming you mean 244+?=269, the answer is 25. Hope this was right
