Answer:
864
Step-by-step explanation:
Volume of cup = ⅓pi×r²×h
Diameter = 2, radius = 1
= ⅓×3.142 × 1² × 4 = 4.1893333333 in³
To empty the sink, 864 scoops will be required
(3617/4.1893333 = 863.383)
(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
Answer:
7/16
Step-by-step explanation:
Let the fraction be x/y
(x+5)/(y+5) = 4/7
7x + 35 = 4y + 20
7x + 15 = 4y
(x-1)/(y-1) = 2/5
5x - 5 = 2y - 2
2y = 5x - 3
7x + 15 = 2(5x - 3)
7x + 15 = 10x - 6
3x = 21
x = 7
2y = 5(7) - 3
2y = 32
y = 16
x/y = 7/16
Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)
