Answer:

B

Step-by-step explanation:

~ symbol refers to similarity. ∆ABC ~∆XYZ means that the two triangles are similar(Same shapes, not the same size).

3(x-4)(2x+5)

= 3×(x-4)×(2x+5)

= (3x-12)(2x+5)

= 6x²+15x-24x-60

= 6x²-9x-60

[tex]3( {2x }^{2} + 5x - 8x - 20) \\ 3( {2x}^{2} - 3x - 20) \\ {6x}^{2} - 9x - 60 \\(6x + \frac{5}{2} )(x - 4)[/tex]

The angle B will be equal to ∠B=53.13 degrees.

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.

It is given that:-

Three sides of the triangle are:- a= 3, b=4  and c =5

The angle B will be calculated by the following formula;-

[tex]\angle B=Cos^{-1}\dfrac{a^2+c^2-b^2}{2ac}\\\\\\\angle B=Cos^{-1}\dfrac{3^2+5^2-4^2}{2\times 3\times 5}\\\\\\\angle B=Cos^{-1}(0.6)\\[/tex]

∠B=53.13 degrees

Hence the angle B will be equal to ∠B=53.13 degrees.

Connect C and E with a straightedge is the next step in order to complete the construction of an equilateral triangle.

It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)

We have:

Circle with centre P and point A along the circle's edge, arcs along the circle at points B, C, D, E, and F in alphabetical order, and a line segment connecting points A and C.

A triangle with three sides that are all the same length and three angles that are all the same size (60°) is called an equilateral triangle.

Connect C and E with a straightedge is the next step in order to complete the construction of an equilateral triangle.

Thus, connect C and E with a straightedge is the next step in order to complete the construction of an equilateral triangle.

Mixed Number Form: x = 1 45/299

Decimal Form: x = 1.15050167…

Step-by-step explanation:

Sum of the interior angle of any triangle must equal to 180 degrees thus :

[tex]53 + 90 + t = 180[/tex]

[tex]143 + t = 180[/tex]

[tex]t = 37[/tex]

Thus angle T has a measure of 37° .

Answer: 37

Explanation: Angle S is a right triangle because ST is tangent to circle Q.
180 - 90 - 53 = 37

Explanation:

There are 8 red marbles out of 22 total

8/22 = 4/11 is the probablity of randomly selecting red.

If the first marble is put back, then that probability will not change.

The probability of two red marbles in a row is (4/11)*(4/11) = 16/121

Side note: 16/121 = 0.1322 = 13.22% approximately

Answer:

The next term of the sequence is represented by the point (5, –64)

Step-by-step explanation:

From inspection of the graph, the first four terms of the sequence are:

Each x-value increases by 1 for each consecutive term.

Each y-value is the previous y-value multiplied by -2.

Therefore, it is a geometric sequence with a common ratio of -2.

Following the above rule, if the last term in the sequence is (4, 32), then the next term in the sequence will be:

So, the next term of the sequence is represented by the point (5, –64)

Step-by-step explanation:

Answer:

  $8,287,429

Step-by-step explanation:

The total profit will be the sum of a geometric series. The formula for that sum is ...

  Sn = a1 × (r^n -1)/(r -1)

where a1 is the first term, r is the common ratio, and n is the number of terms.

__

Here, the series has first term $140,000, common ratio 1+0.20 = 1.2, and we want the total of 14 terms. The total profit is ...

  S14 = ($140,000) × (1.2^14 -1)/(1.2 -1) ≈ $8,287,429

In the first 14 years of operation, the total profit would be $8,287,429.

Find the area of the triangle side, then multiply by the length of the prism.Area of triangle = 1/2 x height x baseArea  = 1/2 x 2 x 3 = 3 square cmVolume = 3 x 4 = 12 cubic cm.Answer is A)

Step-by-step explanation:

The volume of the cone is 254.85 cubic units

The side length of the equilateral triangle is given as:

l = 12√3

Calculate the radius (r) of the cone using:

r = l/2

r = 12/2√3

r = 6√3

Calculate the height of the cone using:

[tex]h = \sqrt{l^2 + (l/2)^2[/tex]

This gives

[tex]h = \sqrt{(12\sqrt 3)^2 + (6\sqrt3)^2[/tex]

Evaluate

[tex]h = \sqrt{540[/tex]

h = 22.24

The volume of the cone is then calculated as:

V = 1/3πr²h

This gives

V = 1/3π * (6√3)² * 22.24

Evaluate

V = 254.85

Hence, the volume of the cone is 254.85 cubic units

speed = distance/time

distance = speed × time.

so, for the first 4 hours

distance = 60 m/h × 4 h = 240 miles

and for the next hour

distance = 40 m/h × 1 h = 40 miles

she traveled therefore

240 + 40 = 280 miles

If the scale factor is 3/4. Then the perimeter of the original triangle will be 66.67 units.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

A triangle with a perimeter of 50 units is the image of a triangle that was dilated by a scale factor of 3/4.

Then the perimeter of the preimage, the original triangle, before its

dilation will be

Let c be the perimeter of the original triangle.

Then we have

Answer:

Let x be the number of left handed female students and let y be the number of left handed male students.

Then the number of right handed female students will be 5x and the number of right handed male students will be 9y. Since the total number of left handed students is 18 and the total number of right handed students is 122, the following system of equations must be satisfied.

x+y=18 and 5x+9y=122

Solving this system gives x=10 and y=8.

Thus, 50 of the 122 right handed students are female. Therefore, the probability that a right handed student selected at random is female is   the fraction  50/122

which to the nearest thousandth is 0.410.
