27 treats per 3 minutes = 9 : 1
if the ratio is 9:1, multiply by 8, and you get
72 treats per 8 minutes
you're welcome!
X = 66 degrees. (Co interior angles are supplementary, add up to 180)
2y + 4 = y + 7
2y - y = 7 - 4
Y = 3
Let's check the dot product .
v.w = 5(4)-2(10) = 20 -20 =0
So the dot product is not 20 . And since the dot product is zero, so they are perpendicular.
And the y component of w is 10.
So correct options are first and third .
In total the bag has 6 cubes and 1 means the white cube you are pulling out from the bag so there is 1/6 chance of getting a white cube.
The radius is 6
Complete the square on the equation and get
(x-6)^2 + (y-6)^2 =36
The circle equation is
(x-h)^2 + (y-k)^2 = r^2
Center(h,k) r=radius
