A square has a perimeter of 20 cm what is the length of its diagonal rounded to the nearest tenth

Answers

-- All 4 sides of a square are the same length.
   The perimeter is 20 cm.
   So each side is  (20/4)  =  5 cm.

-- If you cut the square along its diagonal, and throw one piece away ...

   You have a right triangle.
   The legs are sides of the square ... 5 cm each.
   The hypotenuse is the diagonal of the square, which you have to find.

-- The (hypotenuse of any right triangle)²

                 = (the length of one leg)² + (the length of the other leg)² .

       (Diagonal)²  =  (5 cm)² + (5 cm)²

       (Diagonal)²  =  (25 cm²) + (25 cm²)

       (Diagonal)²  =  (50 cm²)

         Diagonal  =  √(50 cm²)  =  7.07 cm

                                         or    7.1 cm  rounded to the nearest tenth.
multiply the length of one side by the square root of 2.

   20
√2 = 28.28
Rounded to the nearest tenth:
28.28
→28.3

28.3 is the final answer

Compare and contrast the terms scale and scale factor.

The scale factor between two shapes is the same as the ratio of their perimeters.

Ok hey guys 11 its and explain so convert this into vertex form y=-2x^2 +16x-37

Answers

vertex form is y=a(x-h)^2+k

basically complete the square

isolate the x^2 and x term, then  undistribute the -2
y=-2(x^2-8x)-37
take 1/2 of -8 and square it and add 0 to inside
y=-2(x^2-8+16-16)-37
complete the squaer
y=-2((x-4)^2-16)-37)
distribute the -16 to the -2
y=-2(x-4)^2+32-37
y=-2(x-4)^2-5

What does this mean

Answers

Because the two sides opposite the 2 angles are identical, the two angles would also be identical.

Angle B would equal 52 degrees.

The answer is A.

Base angles of Isosceles triangles are equal. So, the measure of Angle B = 52°.




starting at the top if you cut a square pyramid in half using a single cut, what is the shapes of the newly-exposed section?

Answers

If you cut a squarepyramid in half using a single cut that passes through the apex (top) and the center of the square base, the newly-exposed section will be a triangle.

What is a pyramid?

A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.

The volume of a pyramid with a square base is given as:

Volume = 1/3 x base area x height

We have,

The triangle will have the same shape as the base of the pyramid, with its vertices at the midpoints of three of the original pyramid's edges.

Each of these edges will be bisected by the cut, so the triangle will have the same perimeter as the base of the pyramid, but its area will be half that of the base.

The remaining half of the pyramid will also be a triangularpyramid with the same base and congruent triangular faces.

Thus,

If you cut a squarepyramid in half using a single cut that passes through the apex (top) and the center of the square base, the newly-exposed section will be a triangle.

28/29 and 30 plz short explanation thanks

Answers

Integers are numbers like ...-3, -2, -1, 0, 1, 2, 3... and so on. So, according to this definition, let's solve this problem:


28. We know that the product of three integers is -3. So, the statement states that we have three factor, so:


a.b.c = -3


The possible values of the factors are:

  • Factors are: 3, 1 and -1 in which case:

(3)(1)(-1) = -3

  • Factors are: -3, 1 and 1 in which case:

(-3)(1)(1) = -3


29. In this problem we know two nonzero integers, that is, they cannot be equal to zero. Thus, they must have different sign, that is, one of them must be positive and the other negative.For instance:


  • -9 and 2

(-9)(2) = -18, So -18 is less than -9 and 2


Another example:


  • 1 and -8

(1)(-8) = -8, So -8 is equal to -8 and -8 is less than 1.


30. The sign of the product of two integers with the same sign is positive, that is:


(+)(+) = (+) and

(-)(-) = (+)


So, the sign of the product of three integers with the same sign are two options:

  • Option 1. The three integers are positive in which case:

(+)(+)(+) = (+), So the sign of the product is positive


  • Option 2. The three integers are negative in which case:

(-)(-)(-) = (-), So the sign of the product is negative.


This option two gives us that result because:


(-)(-) = (+) and (+)(-) = (-)
