Answer: 93 and 4/5
Step-by-step explanation:
6 7/10 divided by 1/14
= 67/10 divided by 1/14
= 67/10 x 14/1
= 67/5 x 7/1
= 469/5
Answer:
100.... my kind sir
Step-by-step explanation:
Answer:
Y=3
Step-by-step explanation:
-1= 1/2
1/2=-1
x=-1
y=3
Hope this helps!
the standard form for a horizontal ellipse is
X^2/a^2 + y^2/b^2 = 1
Substitute 54 for b and and use (8,18) as the
point to find a
x=8
y=18
8^2/a^2 + 18^2/54^2 =1
64/a^2 + 324/2916 = 1
324/2916 reduces to 1/9
64/a^2 + 1/9 = 1
64/a^2= 1-1/9
64/a^2 = 8/9
64*9/8 = a^2
576/8 = 72
A^2 = 72
A = square root(72) = 8.485
So formula
would be x^2/72 + y^2/2916 =1
In both problems, the sum of side lengths is the perimeter. Opposite sides of a parallelogram (or rectangle) are equal in length, so you can find the perimeter by doubling the sum of adjacent sides.
