Answer:
90 feet
Step-by-step explanation:
320 (1/8) = 40
3/4 (40) = 30 yards
1 yard = 3 feet
30 (3) = 90 feet
<u>Answer:</u>
D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11
<u>Step-by-step explanation:</u>
We are given the following two expressions:
![3x^2-4y^2=25](https://tex.z-dn.net/?f=3x%5E2-4y%5E2%3D25)
and
![-6x^2-2y^2=11](https://tex.z-dn.net/?f=-6x%5E2-2y%5E2%3D11)
Now if we look at the option D)
and
, we can observe that the earlier part in the given expression is just a simplification of 6x^2 - 8y^2 = 50.
![6x^2 - 8y^2 = 50\\\\2(3x^2-4y^2) = 50\\\\3x^2-4y^2 = \frac{50}{2} \\\\3x^2-4y^2=25](https://tex.z-dn.net/?f=6x%5E2%20-%208y%5E2%20%3D%2050%5C%5C%5C%5C2%283x%5E2-4y%5E2%29%20%3D%2050%5C%5C%5C%5C3x%5E2-4y%5E2%20%3D%20%5Cfrac%7B50%7D%7B2%7D%20%5C%5C%5C%5C3x%5E2-4y%5E2%3D25)
and the later part
is already the same.
Therefore, the correct answer option is D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11.
Answer:
...
Step-by-step explanation:
the central angle is the same as the arc
mDE= 104°
mFE= 76°
mDEF= 180°
mCFD= 180°
mDFE= 256°
10*8=80
3*8=24
80-24=56
