BRAINIEST!!! only answer if you know and can give an explanation, will report for non-sense answers

Answer:

Below

Step-by-step explanation:

For a given shape to be a rhombus, it should satisfy these conditions:

● The diagonals should intercept each others in the midpoint.

● The diagonals should be perpendicular.

● The sides should have the same length.

We will prove the conditions one by one.

■■■■■■■■■■■■■■■■■■■■■■■■■■

Let's prove that the diagonals are perpendicular:

To do that we will write express them as vectors

The two vectors are EG and DF.

The coordinates of the four points are:

● E(0,2c)

● G (0,0)

● F (a+b, c)

● D (-a-b, c)

Now the coordinates of the vectors:

● EG (0-0,0-2c) => EG(0,-2c)

● DF ( a+b-(-a-b),c-c) => DF (2a+2b,0)

For the diagonals to be perpendicular the scalar product of EG and DF should be null.

● EG.DF = 0*(2a+2b)+(-2c)*0 = 0

So the diagonals are perpendicular.

■■■■■■■■■■■■■■■■■■■■■■■■■■

Let's prove that the diagonals intercept each others at the midpoints.

The diagonals EG and DF should have the same midpoint.

● The midpoint of EG:

We can figure it out without calculations. Since G is located at (0,0) and E at (0,2c) then the distance between E and G is 2c.

Then the midpoint is located at (0,c)

● The midpoint of DF:

We will use the midpoint formula.

The coordinates of the two points are:

● F (a+b,c)

● D(-a-b,c)

Let M be the midpoint of DF

●M( (a+b-a-b,c+c)

● M (0,2c)

So EG and DF have the same midpoint.

■■■■■■■■■■■■■■■■■■■■■■■■■■

There is no need to prove the last condition, since the two above guarante it.

But we can prove it using the pythagorian theorem.

Is 1044 divisible by 2,3,5,6,9 or 10
Travka [436]
1044 is divisible by 2 as it is an even number
To check whether it divides by three, just add all the digits and see if that is divisible by three, so 1+0+4+4 is 9 and 9/3= 3, so 1044 is divisible by three
Not divisible by 5 because it does not end in 5 or 0
Divisible by 6, 1044/6= 174
Divisible by 9, 1044 /9 gives 116
Not divisible by 10 because it does not end in 0

Plz help
alisha [4.7K]

The width of the actual yard is 50 feet wide. Since the scale from the drawing to real life is 1 inch for every 10 feet, simply multiply 1:10 by the same number on both sides to get an equivalent ratio using the given scale. Basically, 1 inch : 10 feet * 5:5 equals 5 inches for every 50 feet.

Alternative:

1 inch   =  5 inches

10 feet =  ? feet

If you multiply the numerator by 5, you multiply the denominator by five to ensure the ratio and scale are still accurate and equivalent. 10 * 5 = 50.
