In the 2000 Summer Olympics Russia earned twice as many gold medals as Australia. Italy earned three less than Australia. They earned 61 gold medals in total. How many gold medals did Italy earn?
(PLEASE ANSWER!!)

Answers

Answer: x = 16

Step-by-step explanation: Let X stand for Australia.

2x for Russia

x for Australia

x-3 for Italy

Equation: 2x + x + x - 3 = 61

Combine: 4x - 3 = 61

Add 3: 4x = 64

Divide: x = 16

But it back: 2(16) + 16 + 16 - 3 = 61 --> 64 - 3 = 61

So the answer is x = 16.

Find the coordinates of midpoint F.
(Enter answer in simplified form.)
A(-3a, b)
B3a b)
F= ([?],[])
Midpoint Formula : M = ()
Ca 5b

Answers

Answer:

The coordinates are (0,b)

Step-by-step explanation:

Here, we want to find the coordinates of the midpoint F

as we can see, F is between A and B

we proceed to use the midpoint formula

The midpoint formula is;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

(x1,y1) = (-3a, b)

(x2,y2) = (3a, b)

The substitution of these values will thus yield;

(-3a + 3a)/2, (b + b)/2

= (0/2), (2b/2)

= (0, b)

Pythagorean theorem

Answers

a²+b²=c² is pythagorean theorem :)

Pythagorean theorem

in the right angle triangles there is a relationship that governs the length of the three sides. if we knows the length of any two sides, the third side may be calculated by the use of the Pythagorean theorem.

This theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

we only use Pythagorean theorem to find the length of the missing side of a right angled triangle only.

Which similarity transformation could map ADEF to AD'E'F'? dilation and reflection dilation and translation rotation and dilation o rotation and reflection

Answers

Answer:

The correct answer is indeed C. Rotation and dilation :)

The similarity transformation that maps ΔDEF to ΔDEF is rotation and dilation.

What is dilation?

Dilation involves scaling an object by multiplying the distance between all of its points and a fixed point, called the center of dilation, by a constant factor.

The factor can be greater than 1, in which case the object gets larger, or it can be between 0 and 1, in which case the object gets smaller.

The center of dilation can be located anywhere in the plane.

We have,

Rotation and dilation are both transformations in geometry that can be used to change the size and shape of an object.

Rotation involves rotating an object around a fixed point, called the center of rotation.

The object remains the same size and shape, but its orientation changes.

Dilation involves scaling an object by multiplying the distance between all of its points and a fixed point, called the center of dilation, by a constant factor.

Now,

We see that,

There is rotation and dilation on ΔDEF.

Thus,

The similarity transformation that maps ΔDEF to ΔDEF is rotation and dilation.

If Triangle ABC~trIangle DEC, find the value of x and y."

Answers

Answer:

The right answer would be (D) x = 1.

Step-by-step explanation:

So since triangles ABC and DEC are congruent to each other, your gonna try to find the value of x. So from the figure we know that AB = 4x - 1, BC = 4, AC = 5, DE = x+2, CE = 4 and EC = 5. And since ΔABC ≅ ΔDEC the corresponding sides would be equal. And after, we will have :

AB = DE

4x - 1 = x + 2

4x - x =2 + 1

3x = 3

x = 1

So, as it shows, the value of x is one. So (D) x = 1 is the right answer. Hope this helped! :)

What does distance preserving mean

Answer:

A rotation is distance preserving. All points in space are rotated but the distance between any 2 points before and after the rotation is preserved.

Answer: A map f : X → Y is called an isometry or distance preserving if for any a,b ∈ X one has. An isometry is automatically injective; otherwise two distinct points, a and b, could be mapped to the same point, thereby contradicting the coincidence axiom of the metric d.
