<span>1.) The polygon whose vertices in the coordinate plane are (-2,3) (2,3) (2,0) (-2,0) is a rectangle with length = 4 units and width = 3 units.
Therefore, only equiangular.

2.) </span>T<span>he polygon whose vertices in the coordinate plane are (3,3) (5,0) (5,-3) (1,-3) (1,0) is a triangle on top of a rectangle which is neither equilateral nor equiangular nor regular.
i.e. none of the above.

3.) </span>T<span>he polygon whose vertices in the coordinate plane are (5,0) (5,-3) (1,-3) (1,0) is a rectangle.

frozen [14]

In a directly proportional relationship, increasing one variable will increase another. The weight of the roof whose depth is 1.75 inches is 6,300 pounds.

<h3>What is the directly proportional relationship?</h3>

In a directly proportional relationship, increasing one variable will increase another. This directly proportional relationship between p and q is written as p∝q where that middle sign is the sign of proportionality.

Let there are two variables p and q. Then, p and q are said to be directly proportional to each other if p = kq, where k is some constant number called the constant of proportionality.

Given the hail's weight varies directly with its depth. Therefore, the relation can be written as,

Weight ∝ Depth

W∝D

Introducing the constant to remove the proportionality we will get the equation as,

W = kD

1800pounds = k × 0.5 inches

3600ponds/inches = k

Now, the weight of the roof whose depth is 1.75 inches can be written as,

W = kD

W = 3600 × 1.75

W = 6,300 pounds

Hence, the weight of the roof whose depth is 1.75 inches is 6,300 pounds.

A company is designing a new cylindrical water bottle. The volume of the bottle will be 156156 cmcubed3. The height of the water
DaniilM [7]

Answer: the radius is 2.61 cm

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

Volume = 156 cm³

Height = 7.3 cm

Therefore,

156 = 3.14 × r² × 7.3

156 = 22.922r²

r² = 156/22.922 = 6.81

Taking square root of both sides of the equation, it becomes

r = 2.61 cm

At 2pm two military convoys leave Eagle River Wisconsin one headed North and 1 headed South the convoy headed North averages 50
skelet666 [1.2K]

Answer:

The answer to the question is

1.5 hours that is;

When the distance between them is more then 135 miles is after 1.5 hours and they will lose radio contact at 3:30 p.m.

Step-by-step explanation:

We note that

The speed of the military convoy headed north =50 mph

The speed of the convoy headed south  = 40 mph

Let t be the time taken for the two convoys to be 135 miles apart

The time taken for the two convoys to be 135 miles apart is given by

50×t miles+ 40×t miles= 135 miles

That is 90×t miles = 135 miles

                  t = 135/90 = 1.5 hrs
