The two right scalene triangles shown are similar , but not congruent. Which statement about the triangles is not true

The correct answer is C. 604,800.

To calculate this, we can use the formula for permutations:

P(n, k) = n! / (n-k)!

In this case, we have 9 digits (0-9), and we want to create a 7-digit phone number. Since the first digit cannot be 0, we have 9 choices for the first digit, and 9 remaining choices for each subsequent digit (since numbers cannot be repeated).

So, the total number of possible phone numbers is:

P(9, 7) = 9! / (9-7)! = 9 × 8 × 7 × 6 × 5 × 4 × 3 = 604,800

Therefore, the correct answer is C. 604,800.

Answer:

Option A is the correct answer.

Step-by-step explanation:

Given  

The coordinates of point A = (2m, 2n)

The diagram is plotted on the graph, where O represents origin.

As we know that O is the origin whose coordinates are (0,0)

The formula for mid-point is:

Mid-point=((x_1+x_2)/2,(y_1+y_2)/2)

So,

The x-coordinate of mid-point of OA=(2m+0)/2

=2m/2

=m

The y-cooridnate of mid-point of OA=(2n+0)/2

=2n/2

=n

So the mid-point of OA is (m,n) ..

Answer:

96cm2

Step-by-step explanation:

Area of rhombus=1÷2×d1×d2

=1÷2×12×16

=96

96cm². The are of the rhombus of the image is 96cm².

The key to solve this exercise is breaking down the rhombus in four equals right triangles, each triangle has the sides 10cm, 8cm and 6cm. We can calculate the area of one right triangle and multiply by 4 in order to get the total area of the rhombus.

The area of a triangle is [tex]A_{t}=\frac{bxh}{2}[/tex] where b is the base and h is the height.

The base of the one right triangle is 8cm and the height is the leg adyacent to the right angle that is 6cm. Calculating the area of the right triangle:

[tex]A_{t}=\frac{8cmx6cm}{2}=\frac{48cm^{2} }{2} =24cm^{2}[/tex]

The total area of the rhombus is [tex]A = 4A_{t}[/tex]

[tex]A = 4x24cm^{2}=96cm^{2}[/tex]

Answer:

(D) 3, 3, 6

Step-by-step explanation:

The triangle inequality says the sum of the shortest two legs must be longer than the longest. In the case of {3, 3, 6}, the sum is exactly equal to the longest, so the "triangle" will look like a line segment and have zero height and zero area,

Some authors describing the triangle inequality find that to be an acceptable condition. Apparently the author of this question does not.

For this case we must find the solutions of the following quadratic equation:

[tex]x ^ 2-5x-1 = 0[/tex]

We solve by means of

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}[/tex]

Where:

[tex]a = 1\\b = -5\\c = -1[/tex]

Substituting:

[tex]x = \frac {- (- 5) \pm \sqrt {(- 5) ^ 2-4 (1) (- 1)}} {2 (1)}\\x = \frac {5 \pm \sqrt {25 + 4}} {2}\\x = \frac {5\pm \sqrt {29}} {2}[/tex]

Finally, the roots are:

[tex]x_ {1} = \frac {5+ \sqrt {29}} {2}\\x_ {2} = \frac {5- \sqrt {29}} {2}[/tex]

Answer:

[tex]x_ {1} = \frac {5+ \sqrt {29}} {2}\\x_ {2} = \frac {5- \sqrt {29}} {2}[/tex]

Answer:

[tex]y=\frac{1}{52}x^2[/tex]

Step-by-step explanation:

The focus of the parabola is (0,13)

and the directrix is y=-13.

The equation of this parabola is given by:

[tex]x^2=4py[/tex]

The vertex of this parabola is at the origin.

The value of p is the distance from the vertex to the focus.

p=13-0=13

The equation of the parabola is

[tex]x^2=4(13)y[/tex]

[tex]x^2=52y[/tex]

Or

[tex]y=\frac{1}{52}x^2[/tex]

Answer:

86 - 9x

Step-by-step explanation:

In a rhombus, adjacent angles are supplementary.  So:

∠ADE + ∠EDC + ∠DCE + ∠ECB = 180

Also, the diagonals of a rhombus are perpendicular.  Since the sum of a triangle's angles add up to 180:

∠EDC + 90 + ∠DCE = 180

∠EDC + ∠DCE = 90

Substituting:

∠ADE + 90 + ∠ECB = 180

∠ADE + ∠ECB = 90

∠ADE + 9x + 4 = 90

∠ADE = 86 - 9x

∠ADB is the same as ∠ADE, so the answer is 86 - 9x.

Angle ∠ADB is 41°.

It is a polygon that has four sides and four corners. The sum of the internal angle is 360 degrees. In Rhombus opposite sides are parallel and all sides are equal. And its diagonals intersect at the right-angle.

Given

A rhombus ABCD,

∠DCA = 13x - 16

∠ACB = 9x + 4

The measure of ∠ADB.

We know that the angle ∠DCA and  ∠ACB are equal.

13x - 16 = 9x + 4

13x - 9x = 4 + 16

       4x = 20

         x = 5

So the angle ∠DCA and ∠ACB will be

∠DCA = 13x - 16 = 64 - 16 = 49

∠ACB = 9x + 4 = 45 + 4 = 49

The sum of the internal angle is 360 degrees

∠ABC + ∠BCD + ∠CDA + ∠DAB = 360

∠CDA + ∠BCD + ∠CDA + ∠BCD = 360

                            ∠ABC + ∠BCD = 180

                                  ∠CDA + 98 = 180

                                          ∠CDA = 82

So we know

2 x ∠ADB = ∠CDA

2 x ∠ADB = 82

     ∠ADB = 41

Thus, Angle ∠ADB is 41°.

An equation for the number of trinkets in the warehouse after x days:

8,000 + 3,000x = 50,000

How many days will it take to fill the warehouse?

8,000 + 3,000x = 50,000

3,000x = 42,000

x = 14

Answer: Multiply 100 to both the numerator and denominator.

The problem is simplifying a sequence of numeric addition. It involves finding the average of a range of sequential odd and even numbers and dividing the two averages. This simplifies to 100/101.

The problem presented is to simplify the sequential addition of odd numbers from 1 to 199, divided by the sequential addition of even numbers from 2 to 200. This is also known as calculating the average or mean of a set of sequential numbers, a concept in statistics.

To solve this, we need to understand that the average of a set of sequential numbers can be found by taking the sum of the first number and the last number, dividing it by two. Therefore, the sum of odd numbers from 1 to 199 can be simplified as (1+199)/2, and the sum of even numbers from 2 to 200 can be simplified as (2+200)/2.

Simplifying these gives us 100 for odd numbers and 101 for even numbers. Therefore, the simplification of the presented sequence is 100/101.

Choice C is correct

Step-by-step explanation:

The first step is to re-write the equations in exponential form.

The first equation can be written as;

[tex]\frac{M}{N}=10^{4}[/tex] since the base is 10 and 4 the exponent.

The second equation can be written as;

[tex]\frac{P}{N}=10^{5}[/tex]

The second step is to make N the subject of the formula in both equations.

Solving for N from this equation [tex]\frac{M}{N}=10^{4}[/tex], yields;

[tex]N=\frac{M}{10^{4}}[/tex]

Solving for N from the second equation [tex]\frac{P}{N}=10^{5}[/tex], yields;

[tex]N=\frac{P}{10^{5}}[/tex]

Therefore;

[tex]\frac{M}{10^{4}}=\frac{P}{10^{5} }\\\\P=10M[/tex]

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). 6.9

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables. As opposed to this, an equation with variables is an algebraic equation.

Answer:

Angle 8 = Angle 4

Step-by-step explanation:

Answer:

4.  ∠3 and ∠5

5.  75°

Step-by-step explanation:

4. Same-side interior angles.

If you look at the figure, the INTERIOR angles are those between the two parallel lines (JL and MP), these are angles #3, #4, #5 and #6. The other angles are exterior angles.

The question asks for same-side... meaning both on the left of NK or on the right side of it.  So, the two sets that match this are: 3 with 5 and 4 with 6.

The last option gives you ∠3 and ∠5, so that's your answer.

That makes sense since angles 1 and 2, present in all other choices, are exterior angles.

5. If ∠4 = 75 degrees, what's the value of  ∠8?

Since JL and MP are parallel lines crossed by another line (NK), we know that  ∠4 and ∠8 will have the same measurement.  Those two angles are located on the same position compared to each other and one of the parallel line.

So, since  ∠3 = 75°,  ∠8 also has to be 75°, same for their opposing angles 2 and 5.  While the other angles are complements... so they're 105 degrees angles.
