HOW CAN THE DISTANCE FORMULA HELP ME DETERMINE WHETHER A QUADRILATERAL ON A COORDINATE PLANE IS A PARALLELOGRAM

1 answer:

The distance formula is derived from the Pythagorean Theorem because the length of one leg of the triangle will always be the difference of the x-coordinates, and the length of the other leg will always be the difference in the y-coordinates<span>

Joanie's curtain company is making curtains for a local hotel. She wants each curtain to be 48 inches long. At the fabric store,

Dima020 [189]

Answer: 224 feet

Step-by-step explanation:

Each curtain is 48 inches long, and she wants to make 56 curtains.

However, the fabric store sells by the foot.

There are two ways to do this:

1) You can convert beforehand.

48 inches= 4 feet because 1 inch=1/2 foot.

Multiply 48 by 1/12 to find how many feet are in 48 inches.

= 48/12

So 48 inches= 4 feet

Now, each curtain is 4 feet. There are 56 curtains to be made.

Now multiply by 4 to find how many feet are in 56 curtains.

56x4=224 feet.

Answer= 224 ft

Or: You can convert afterwards

48x56= how many inches in 56 curtains

= 2,688 inches

Then, convert to feet!

1 inch= 1/12 foot

2688 multiplied by 1/12:

=2688/12

=224 feet

Answer= 224 feet

Either way, you both get 224 feet.

The diagram shows a circle and an equilateral triangle. One side of the equilateral triangle is a diameter of the circle. The ci

Lemur [1.5K]

Answer:

$Area = 101.4 cm^2$ (3 S.F)

Step-by-step explanation:

Diameter of circle (D) = one side of the equilateral ∆

Circumference of the circle = πD = 48 cm

Thus:

πD = 48

Divide both sides by π

D = $\frac{48}{\pi}$ = 15.3 cm (approximated to nearest tenth)

Since all sides an equilateral ∆ are equal, therefore, and the diameter, D, of the circle given is the same as the length of one side of the ∆, therefore, all sides of the equilateral triangle would be 15.3 cm.

Recall that the area of a triangle can be found if we know lengths of the two sides of the ∆ and the measure of the included angle between both sides.

Since an equilateral ∆ has equal angles, each measuring 60°, then we already have all the information needed to calculate the area of the ∆.

Thus:

Length of the two sides = 15.3 cm and

15.3 cm

Included angle = 60°

Use the following formula:

$Area = \frac{1}{2}ab \times Sin(C)$

Where,

a = 15.3 cm

b = 15.3 cm

C = 60°

Plug the values into the formula to find the area.

$Area = \frac{1}{2} \times 15.3 \times 15.3 \times Sin(60)$

$Area = \frac{1 \times 15.3 \times 15.3 \times Sin(60)}{2}$

$Area = 101.4 cm^2$ (3 S.F)
