Using pythagoras theorem formula, c² = a² +b²  We can see that the two shorter sides have the same length which is 5cm

Since all the sides of the triangle are the same, hence the two triangles are congruent.

What is Pythagoras' theorem ?

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

The two shorter sides have the same length which is 5cm

Since all the sides of the triangle are the same, hence the two triangles are congruent.

Let the sides of the triangles be a, b and c. According to Pythagoras theorem;

c² = a² +b²

where:

a is the hypotenuse (longest side)

For triangle A:

c = 13

b = 12

Get "a"

13² = 12² +b²

b² = 25

=> b = 5 cm

Similarly for triangle B:

c² = 5² +12²  = 169

=> c=13 cm

We can see that the two shorter sides have the same length which is 5cm

Since all the sides of the triangle are the same, hence the two triangles are congruent.

Answer:

D' (9, 10)

E'( 12,-1)

F'(7,8)

Step-by-step explanation:

The coordinates of triangle DEF will be D(9,10), E(12,-1), and F(7,8) after the translation.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

The given triangle DEF has vertices D (3,5), E(6,-6), and F(1,3).

Triangle DEF has translated 5 units up and 6 units right.

This means that the x-coordinates of the vertices D, E, and F will each be increased by 6, and the y-coordinates of the vertices will each be increased by 5.

After the translation, the coordinates of vertex D will be (3 + 6, 5 + 5) = (9, 10)

After the translation, the coordinates of vertex E will be (6 + 6, -6 + 5) = (12, -1)

After the translation, the coordinates of vertex F will be (1 + 6, 3 + 5) = (7, 8)

So after the translation, the coordinates of triangle DEF will be D(9,10), E(12,-1), F(7,8)

Answer:

$519

Step-by-step explanation:

We know that the one day sale price of the ski set is $324 and the markdowns are specified.

A markdown means a reduction in price, so to find the original selling price we need to add the amount of markdown to the sale price.

The markdown of the ski set is $75 + $120 = $195

So, to find the original selling price we need to add the markdown amount to the sale price:

$324 + $195 = $519

Therefore, the original selling price of the ski set was $519

The missing vertices of the square are B(x, y) = (- 2, 1) and D(x, y) = (6, - 7), respectively.

Squares are quadrilaterals with four sides of equal length and four internal right angles. This kind of quadrilaterals have two diagonals perpendicular to each other. In this case, we know the coordinates of the endpoints of diagonal AC and we need to determine the location of points B and D.

This can be done by means of the following definition: A(x, y) = (a, b), C(x, y) = (c, d), B(x, y) = (a, d), D(x, y) = (c, b). If we know that a = - 2, b = - 7, c = 6 and d = 1, then the location of points B and D are, respectively:

B(x, y) = (- 2, 1), D(x, y) = (6, - 7)

Answer:

x=1

Step-by-step explanation:

To solve the equation, we'll need to get the square roots on one side and the non-square root terms on the other side.

First, we'll add √x to both sides to get:

√2x+4 - √x + √x = 2 + √x

√2x+4 = 2 + √x

Next, we'll square both sides to get rid of the square roots:

(√2x+4)^2 = (2 + √x)^2

2x+4 = 4 + 2√x + x

Then, we'll simplify the right side of the equation:

2x+4 = 4 + 2√x + x

2x+4 = 4 + x + 2√x

Now we'll subtract 4 from both sides

2x = x + 2√x

x = 2√x

Finally, we'll divide by x on both sides

1 = 2√x/x

x = √x

x = 1

Therefore, the solution of the equation is x=1

Answer:

To solve the equation √2x+4 - √x = 2, we can first square both sides of the equation to eliminate the square roots.

Squaring both sides gives: (√2x+4)^2 - (√x)^2 = 2^2

Simplifying the left side gives: 2x+4 - x = 4

Next, we can add x to both sides of the equation to get:

2x+4 = 4 + x

then we can subtract 4 from both sides of the equation to get:

2x = x

then we can divide both sides by x

2 = 1

However, it is not possible to divide by zero, so x = 0 is not a valid solution.

This equation is an extraneous solution because the assumption that x is not equal to 0 led to a valid solution, but when x = 0, the equation is not defined.

Therefore, the solution of √2x+4 - √x = 2 is x = any value except 0.

Answer: D) 7 3/4

Step-by-step explanation:

With averages, we add all the values and divide by the number of values. Here, we know three out of the four days, let's label the day we don't know x. There are four days, so we can divide by four. 7 1/4 is the average, so we can set the equation equal to 7 1/4.

7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x) / 4

Let's multiply both sides by 4 to get rid of the fraction. Let's also add what is in the parentheses

29 = 21 1/4 + x

Now we can isolate x by subtracting 29-21 1/4

so

x = 7 3/4 thus the answer is D

Answer:

D) 7 3/4

Step-by-step explanation:

Let x = amount of last feeding.

7 1/4 = (7 1/2 + 7 3/8 + 6 3/8 + x)/4

4 × 7 1/4 = 7 1/2 + 7 3/8 + 6 3/8 + x

28 + 1 = 7 4/8 + 7 3/8 + 6 3/8 + x

29 = 20 10/8 + x

(20 10/8 is the same as 20 + 10/8 = 20 + 8/8 + 2/8 = 20 + 1 + 1/4 = 21 + 1/4 = 21 1/4)

29 = 21 2/8 + x

29 = 21 1/4 + x

x = 29 - 21 1/4

x = 28 4/4 - 21 1/4

x = 7 3/4

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

A table is given where the first column represents the number of hours a student studied math and the second column represents the number of students.

So, sum of the second column is 35. so it is the total number of students

and, only 9 of them studied mathematics for 5 hours.

Therefore, The probability that a student studied for 4 hours is,
