Given; D is the Midpoint of CE / Prove DE =1/2CE

Mathematics
1 answer:
aleksley [76]3 years ago
6 0

Answer:

Check explanation

Step-by-step explanation:

Here, we want to make a prove;

Mathematically , since D is the midpoint of CE

Then;

CE = CD + DE

Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE

I.e CD = DE

Hence, we can express CE as follows;

CE = DE + DE

CE = 2 DE

Divide both sides by 2

CE/2 = DE

Hence; DE = 1/2 CE

An airplane flying with the wind takes 2 hours to travel a distance
Sever21 [200]

9514 1404 393

Answer:

  • airplane: 225 mph
  • wind: 45 mph

Step-by-step explanation:

The average speed with the wind is (540 mi)/(2 h) = 270 mi/h.

The average speed against the wind is (540 mi)/(3 h) = 180 mi/h.

Let a and w represent the speeds of the airplane and wind, respectively.

  a + w = 270 . . . . speed with the wind

  a - w = 180 . . . . speed against the wind

  2a = 450 . . . . . . sum of the two equations

  a = 225 . . . . . . divide by 2

  w = a -180 = 45

The speed of the airplane is 225 miles per hour; the speed of the wind is 45 miles per hour.

Twice a number plus twice a second number is 310. The difference between the numbers is 55. Find the numbers by writing and solv
yan [13]

The numbers are 105 and 50

<em><u>Solution:</u></em>

Let "x" be the first number

Let "y' be the second number

Twice a number plus twice a second number is 310

Therefore,

twice of x + twice of y = 310

2x + 2y = 310 ---------- eqn 1

The difference between the numbers is 55

x - y = 55 -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 2,

x = 55 + y ------ eqn 3

<em><u>Substitute eqn 3 in eqn 1</u></em>

2(55 + y) + 2y = 310

110 + 2y + 2y = 310

4y = 310 - 110

4y = 200

<h3>y = 50</h3>

<em><u>Substitute y = 50 in eqn 3</u></em>

x = 55 + 50

<h3>x = 105</h3>

Thus the numbers are 105 and 50

Suppose a universal set consists of natural numbers that
LenKa [72]

To set up a venn diagram, you need the following details below

  • Set A = ( 3, 6, 9, 12, 15 )
  • Set B = ( 1, 3, 5, 7, 9. 11, 13, 15 )
  • A∩B = ( 3, 9 )
  • U = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)

<h3>Meaning of a set and a venn diagram</h3>

A set is the orderly collection of elements, material, numbers and items that satisfy a condition.

A set could be finite or infinite.

A venn diagram is a diagramatic representation of a set using circles. it mostly represents a finite set.

In conclusion, you can use the details above to draw your venn diagram.
