yes the number is is proportional . 3$ a rose in sets of 3 and up . that give you a price for 15 at 45 $ so the cost of 30 Rose's would be 90$.
Answer:
9.93 liter approximately 10 liter
Step-by-step explanation:
3 days = 3/2 quart
3 week = 3/2/3 × 21 quarts
= 1/2×21
=21/2 quarts
now
1 quart = 0.946 liter
21/2 quart = 0.946×21/2 liter
21/2 quart = 9.93 liter

3-8I am right or wrong and the answer is 5
The easiest way is to try the point (-4,1), that is, x=-4, y=1,
to see which equation works.
b works.
The usual way to do it is to find the equation of the circle
standard form of a circle is (x-h)²+(y-k)²=r², (h,k) are the coordinates of the center, r is the radius.
in this case, the center is (-2,1), so (x+2)²+(y-1)²=r²
the given point (-4,1) is for you to find r: (-4+2)²+(1-1)²=r², r=2
so the equation is (x+2)²+(y-1)²=2²
expand it: x²+4x+4+y²-2y+1=4
x²+y²+4x-2y+1=0, which is answer b.
