Answer:

Long leg = 3√30 yards.

Step-by-step explanation:

So (6√10) / x = 2 / √3

2x = 6√10√3

x = 3√10√3

x = 3√30

Dilations help me please

8_murik_8 [283]

Answer:

D'(1, - 1 )

Step-by-step explanation:

Assuming the dilatation is centred at the origin, then multiply the coordinates of D by $\frac{1}{2}$ , that is

D(2, - 2 ) → D'( $\frac{1}{2}$ (2) , $\frac{1}{2}$ (- 2) ) → D'(1, - 1 )

The Perimeter or a regular pentagon is 41.5cm. Write and solve an equation to determine the length of each side of the pentagon

olchik [2.2K]

Answer:

8.3 cm

Step-by-step explanation:

So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.

Perimeter (P) = s+s+s+s+s (sides)

P: 41.5 cm ÷ 5 =

8.3 cm

We know this is correct because:

8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5

Hope this helps!
