the breadth of a rectangular handkerchief is 10 cm shorter than its length .if the perimeter of the handkerchief is 100cm. find its length and breadth..
plz help me​

Answers

Step-by-step explanation:

Perimeter = 2(l+b)

2(x+x-10)=100cm

(x+x-10)= 100 divided by 2

(x+x-10)=50

2x-10=50

2x=50+10,60

x=60 divided by 2

X =30

Length = 30cm

Breadth= 30-10= 20cm

PLEASE MARK MY ANSWER AS THE BRAINILIEST!

Answer:

solution given:

length[l]=xcm(let)

breadth [b]=(x-10)cm

perimeter of rectangle [P]=100cm

we have

P=2[l+b]

100cm=2[x+x-10]

2x-10=[tex] \frac{100}{2} [/tex]

2x=50+10

x=[tex] \frac{60}{2} [/tex]

:.x=30cm

So

length[l]=x=30cm

breadth [b]=(x-10)=30-10=20cm

The ratio of the perimeter of a square A and square B is 4:3. The side of square B is 3 m less than the side
of square A. What is the length of the side of square A?
please answer

Answers

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12

  (a)  A'(-2, 1), B'(-4, -3), C'(-7, 0)

Step-by-step explanation:

If X is the center of rotation, the coordinates of point P are transformed like this:

  P' = -(P -X) +X

  P' = 2X -P

  (x, y) ⇒ (2(-5) -x, 2(3) -y)

  (x, y) ⇒ (-10-x, 6-y)

__

Your points are transformed to ...

  A(-8, 5) ⇒ (-10-(-8), 6-5) = A'(-2, 1)

  B(-6, 9) ⇒ (-10-(-6), 6-9) = B'(-4, -3)

  C(-3, 6) ⇒ (-10-(-3), 6-6) = C'(-7, 0)

These coordinates match the first choice.

Find the value of x.

Answers

12^2+x^2=15^2
144+x^2=225
- 144 -144
=81= 9
X=9

Answer:

x=9

Step-by-step explanation:

Use Pythagorean Theorem -> a^2 + b^2 = c^2

a^2 + b^2 = c^2

(12^2) + b^2 = (15^2)

144 + b^2 = 225

225 - 144 = 81

√81 = 9

x = 9

Memories of a MemoryHave you ever witnessed something amazing, shocking or surprising and found when describing the event that your story seems to change the more you tell it? Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things.First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which phrase from the text most clearly explains the main idea of the third paragraph?Group of answer choices:Memory uses general knowledgeOther memories and other storiesWhen telling a friend about the eventRather than the actual participant Elizabeth bought 5 packets of sunflower seeds.
