6m - 8 = 1/2(-4m + 16)

faltersainse [42]

Answer:

m=2

Step-by-step explanation:

6m - 8 = 1/2(-4m + 16)

Distribute

6m -8 = -2m +8

Add 2m to each side

6m-8+2m = -2m +8+2m

8m -8 = 8

Add 8 to each side

8m-8+8 = 8+8

8m = 16

Divide each side by 8

8m/8 = 16/8

m=2

Andrew is building a ramp for a snowboarding competition. The rules of the competition say that the height of the ramp must be 8

lara31 [8.8K]

Answer:

The length of the third piece of the ramp is;

D. 9.24 feet

Step-by-step explanation:

The given parameters are;

The height of the ramp = 8 feet

The angle between the piece that forms height and the base = 90°

The angle formed by the third piece connecting the height of the ramp to the furthest point and the 8 foot piece = 30°

Let 'y' represent the 8-foot piece forming the height, and let 'r' represent the third piece, by trigonometric ratio, we have;

$cos(30^{\circ}) = \dfrac{y}{r}$

Therefore, we get;

$cos(30^{\circ}) = \dfrac{8}{r}$

$r = \dfrac{8 \ feet}{cos(30^{\circ})} = \dfrac{8 \ feet}{\dfrac{\sqrt{3} }{2} } = \dfrac{16 \cdot \sqrt{3} \ feet}{3} \approx 9.24 \ feet$

The length of the third piece, r ≈ 9.24 feet
