Westkost [7]

Answer:

the width is 470 ft and the length is 730 ft.

Step-by-step explanation:

Perimeter of a flag is 2l+2w

Let w = width

Let l = w+260

2(w+260)+2w=2,400

2w+520+2w=2400

4w+520=2400

4w=1880

w=470

So, the length would be 470+260, or 730

Therefore, the width is 470 ft and the length is 730 ft.

I hope this helped and have a good rest of your day!

Please help me answer thanks.

Answer:

see explanation

Step-by-step explanation:

Given that M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportion

To find k use the condition when r = 4, M = 160, thus

160 = k × 4³ = 64k ( divide both sides by 64 )

2.5 = k

M = 2.5r³ ← equation of variation

(a)

When r = 2, then

M = 2.5 × 2³ = 2.5 × 8 = 20

(b)

When M = 540, then

540 = 2.5r³ ( divide both sides by 2.5 )_

216 = r³ ( take the cube root of both sides )

r = $\sqrt[3]{216}$ = 6
