Hi 0101sj,
Your Question:
Avril types essays for students from her home. On average, she can type a page in about 10 2/3 minutes. she spends 54 1/2 minutes typing on essay, how many pages if this essay?
Answer:
1 PAGE = 10 2/3 = 10.20
Essay = 54 1/2 = 54.50
54.50 / 10.20 = 5.34313...
She approximately wrote 5 pages.
Completing the square:
x^2 - 18x + y^2 + 8y = -5
x^2-18x +81 - 81 + y^2 + 8y + 16 - 16 = -5.
Then, (x-9)^2 + (y+4)^2 = -5 + 81 + 16 = 92
Then the desired equation is (x-9)^2 + (y+4)^2 = 92.
Answer:
15
Step-by-step explanation:
200-25=175
175/12=14.58333333...
Round up to 15
X-12=-4
x=-4+12
x=8
The answer is A
