<u><em> </em><em>a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal </em></u><em><u>measure</u></em>

<em> Any two opposite sides of a parallelogram are called bases, a distance between them is called a height. If all angles of parallelogram are 90 degree then it can either be a rectangle or a square. ... Only opposite sides of a rectangle are equal unlike square which has all </em><em>.</em>

<em>The opposite internal angles of both a parallelogram and rectangle are equivalent. The main difference is that a rectangle always has angles of 90°, while that of a parallelogram may vary. In other words, the angles of a rectangle are always equal, or equiangular.</em>

<em>The basic difference between rhombus and parallelogram lies in their properties, </em><em>a</em><em>ll the sides of a rhombus have the same length, whereas parallelogram is a rectilinear figure whose opposite sides are parallel.</em>

If 35 gms of pure drug are contained in 150 mls, how many grams are contained in 75 mls?
Leviafan [203]

Answer:

17.5

Step-by-step explanation:

The ratio of "pure drug" to liquid is 35:150

Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2

we can then multiply 35 by the ratio 1/2

35/2=17.5

State the answer

In 75 mls there are 17.5 grams of pure drug

lana [24]

Answer:

  5 feet

Step-by-step explanation:

Add 0.25 to both sides of the equation:

  4.75 +0.25 = x - 0.25 +0.25

  5.00 = x

The original height of the water in the pool was 5.00 feet.

A jet travels 4680 miles against the wind in eight hours and 5720 miles in the wind in the same amount of time what is the rate
Kryger [21]

9514 1404 393

Answer:

  • jet: 650 mph
  • wind: 65 mph

Step-by-step explanation:

The speed against the wind is ...

  4680 mi/(8 h) = 585 mi/h

The speed with the wind is ...

  5720 mi/(8 h) = 715 mi/h

The speed of the airplane in still air is the average of these speeds:

  (585 +715)/2 = 650 mi/h . . . speed in still air

The speed of the wind is the difference between the airplane speed and the speed in the wind:

  715 -650 = 65 mi/h . . . speed of the wind

_____

<em>Additional comment</em>

If p and 'a' represent the speeds of the plane and the air, the speeds with and against the wind are ...

  p + a = with

  p - a = against

If we average these, we get ...

  ((p +a) +(p -a))/2 = (with + against)/2

  p = (with + against)/2 . . . . . . . the formula we used above

Suppose we want to choose 7 colors, without replacement, from 9 distinct colors
Digiron [165]

The number of ways to choose the colors is 36

<h3>How to determine the number of ways?</h3>

The given parameters are:

Colors = 9

Colors to choose = 7

Since order does not matter, then it is combination

This is calculated using:

^nC_r = \frac{n!}{(n - r)!r!}

This gives

^nC_r = \frac{9!}{7!2!}

Evaluate

^nC_r = 36

Hence, the number of ways is 36
