On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne

Mrrafil [7]

<h3>Answer: Choice C. (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

Question:

12345 [234]

Answer:

A. Area in square inches = 1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Step-by-step explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches = 1760 square inches

B. 1 foot = 12 inches

1 inch = $\frac{1}{12}$ feet

1 square inch = $\frac{1}{144}$ feet

∴ 1760 square inches = $\frac{1760}{144}$ feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

We are given the following conversion factor:

$10\text{ miles=}16\text{ km}$

We are asked to determine how many miles are 140 km. To do that we use the quotient of the conversion factor where the unit we want to convert to is in the numerator and the given unit in the denominator. Since we want to find miles we use the following quotient:

$\frac{10\text{ miles}}{16\text{ km}}\times140\operatorname{km}$

Solving the operations we get:

$\frac{10\text{ miles}}{16\text{ km}}\times140\text{ km=87.5 miles}$
