Answer: the length of the flag is 770ft.

The width of the flag is 350 ft

Step-by-step explanation:

Let L represent the length of the national flag.

Let W represent the width of the national flag.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the flag is 2,240ft. This means that 2240 = 2(L + W)

Dividing through by 2, it becomes

1120 = L + W- - - - - - - - - - - -1

if the length is 420 ft greater than the width, it means that

L = W + 420

Substituting L = W + 420 into equation 1, it becomes

1120 = W + 420 + W

2W + 420 = 1120

2W = 1120 - 420 = 700

W = 700 / 2 = 350

L = W + 420 = 350 + 420

L = 770

State if each pair of ratios forms a proportion 12/24 and 3/4
raketka [301]

Answer:

Step-by-step explanation:

12/24 reduces to 1/2, whereas 3/4 does not reduce.  This pair of ratios does not form a proportion.

If both ratios reduced to the same common value, that would represent a proportion.

The point (x, y) is proportional to the point (2, 5). Select all the true statements.
Mnenie [13.5K]

Step-by-step explanation:

(x, y) is a solution to y = 5/2X

(x, y) is a solution to y=x+3.

The ratio of Y/X is equivalent to 5/2

Point (x, y) is the same point as (5, 2).

A straight line through points (2, 5) and (x, y) will pass through the origin.
