The number of chairs on a ski lift is inversely proportional to the distance between them a lift has 70 chairs when there’s spac

Answer:

Space between 80 evenly spaced chairs = 21m

Step-by-step explanation:

So, according to the given statement, we have the following expression:

No. of chairs ∝ $\frac{1}{Distance.Between.chairs}$

70 chairs are 24m apart, so it can be written as:

70 ∝ $\frac{1}{24}$

For, 1 chair , we divide both sides by 70

$\frac{70}{70}$ ∝ $\frac{1}{24(70)}$

1 ∝ $\frac{1}{24 (70)}$ -----------------------(Equation 1)

For 80 chairs:

Multiply both sides of Equation.1 by 80

80 ∝ $\frac{80}{24 (70)}$

80 ∝ $\frac{1}{21}$

So according to the above relation,

80 evenly spaced chairs will have a space of 21 m between them.

Find the area of the polygon.

mart [117]

11x3= 33
3x3=9x2=18
The area would be 51 because you can cut off the two squares making the sides be 3by3 then the rectangle would be 3by11. And you would do HxL. So the area is 51cm
