Choose the kind or kinds of symmetry the following figure
choose the kind or kinds of symmetry the following figure - 1

Answers

Answer 1
Answer:

Answer:

i) Line

ii) point

Step-by-step explanation:


Given is a number 3.  We have to find the kind or kinds of symmetry

On seeing 3, we find that no vertical line can divide 3 into exactly two symmetrical figures.

But if we draw a horizontal line in the middle of 3, we get two symmetrical figures up and down the line.

Hence i) symmetric about a line

Next is imaging the middle of 3 end point.

At that point we find that the figure is symmetrical on all sides of the point

Hence there is also a point symmetry

Kinds of symmetry are

i) Line

ii) point

Answer: Infinitely many solutions

Step-by-step explanation:

1. Cancel −5 on both sides.

4x−4x=0

2. Simplify 4x−4x to 0.

0=0

3. Since both sides equal, there are infinitely many solutions.

Your classmate says 8 to the tenth power times 8 to the third power is equivalent to 8 to the 30th power identify the mistake and give the correct expression#please show your work

Answers

The mistake he did was multiplying the exponents. When multiplying exponents with the same base (8), all you have to do is add the exponents. so the correct term would be 8^13.

5% of what number is 35

Answers

A % is of 100, so I'd find how many times 5 can go into 100, which is 20 times.
20 times 35 is 700. 5% of 700 is 35.
The answer is 700.
the answer to ur problem is 5% of 175 = 35

Which shape is ALWAYS a type of rectangle?

Answers

Square is always a type of rectangle! So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.

It takes Mr. Been 90 seconds to walk up an escalator when it is not moving. It takes Mr. Been 60 seconds to go up, just standing when the same escalator is moving. How many seconds does it take Mr. Been to walk up the moving escalator?

Answers

As per the unitary method, it will take Mr. Bean 120 seconds to walk up the moving escalator.

We can represent this situation as follows:

Time taken to walk up the escalator when not moving = 90 seconds

Distance covered = B * 90

When the escalator is moving, Mr. Bean's effective speed while walking up will be the sum of his walking speed "B" and the speed of the escalator "E." Therefore, he will take 60 seconds to cover the same distance while just standing.

We can represent this situation as follows:

Time taken to go up the escalator while standing = 60 seconds

Distance covered = (B + E) * 60

Now, to find how long it takes Mr. Bean to walk up the moving escalator, we need to find the time it takes for him to cover the same distance as before when it was not moving.

Equating the distances covered in both cases:

B * 90 = (B + E) * 60

Now, let's solve for "E":

90B = 60B + 60E

30B = 60E

E = 30B / 60

E = 0.5B

So, the speed of the escalator "E" is 0.5 times Mr. Bean's walking speed "B."

I think it would take an average of both the numbers so first find the average of 60 and 90 by adding and dividing by two. You will get 75 seconds. That is the answer
