If the perimeter of a parallelogram is 140 m, the distance between a pair of opposite sides is 7 metres

Mathematics

Svetach [21]3 years ago

Answer:

10 m and 60 m.

Step-by-step explanation:

Perimeter = 140 m

Area = 210 m^{2}

Distance between pair of opposite sides = height of the parallelogram = 7 m

Area of parallelogram = \frac{1}{2} x base x height

210 = \frac{1}{2} x base x 7

420 = 7 x base

base = \frac{420}{7}

         = 60 m

The base of the parallelogram is 60 m, which is equal to the length of the opposite side.

Perimeter = 2(a + b)

140 = 2 (a + 60)

140 = 2a + 120

2a = 140 - 120

2a = 20

a = 10 m

Thus, the length of two adjacent sides of the parallelogram are; 10 m and 60 m.

Equations and inequalities!<br> solve for w <br> 11=253-w
Annette [7]

Answer:

w = 242

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • 11=-w + 253
  • -w + 253 = 11

Step 2: Subtract 253 from both sides.

  • -w + 253 - 253 = 11 - 253
  • -w = -242

Step 3: Divide both sides by -1.

  • \frac{-w}{-1}=\frac{-242}{-1}
  • w = 242

Step 4: Check if solution is correct.

  • 11 = 253 - (242)
  • 11 = 253 - 242
  • 11 = 11

Therefore, w = 242.

Have a lovely rest of your day/night.

Change this improper fraction into a mixed number: 89/9
enyata [817]
1) 11 1/8

2) 5/7

3)it would be 233/3 but since that isn't your option try going with 23/3

4) 10 / 16

5) 9/3 = 3 (aka 3/1 ) then 3/9 = 0.3.
Answer for number 5 ⬇
Therefore 9/3 would be your greatest
~the fractions doesn't equal each other~{meaning that the equal sign wouldn't be your answer} ~
~3/9 Would be lesser than 9/3~
~just make the fraction into division .it might help ~
~~~~~~~~~~~~~`~~~~~~~~~~~~~~~~~~~~~~~~~~~
For improper fraction just multiply and add
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Looking for the equivalent of the fractions... try dividing as well
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Example of a improper fraction

Problem : 12 3/5

Work: 12(5) = 60
60 +( 3 )= 63
Answer : 63/ 5
(note: don't worry about the example .... its not apart of the questions you asked.. but you can if you want to ... don't get me wrong.. if it was helpful you can use it )

Pleae help thanks a bunch
zloy xaker [14]
Hello!

You use the Pythagorean theorem to solve this

a^{2} + b^{2} = c^{2}

Put in the values it tells you to

a^{2} + 4.4^{2} = 5.5^{2}

Square the numbers

a^{2} + 19.36 = 30.25

Subtract 19.36 from both sides

a^{2} = 10.89

Take the square root of both sides

a = 3.3

The answer is 3.3

Hope this helps!

Chen has 17CDs. She gives 2 to her brother and buys 4 more. Her brother gives her 1 and she gives 3 to her best friend. How many
d1i1m1o1n [39]

Answer: she has 17 CDs now.

Step-by-step explanation:

The total number of CDs that Chen had initially is 17.

She gives 2 to her brother. This means that she would be having

17 - 2 = 15

She buys 4 more. It means that she would be having

15 + 4 = 19

Her brother gives her 1. So the number that she has is

19 + 1 = 20

she gives 3 to her best friend. Therefore, the number of CDs that Chen has now is

20 - 3 = 17
