Algebra Find the value of x.

Answer:

∠a = 35°  ∠b = 65°

Step-by-step explanation:

a = 35 ° ( alternate interior angles )

( the line x is parallel to line yz hence we can consider XY as a transversal)

∠b + 35° + 80° = 180 ° ( angle sum property of triangle)

∠b+ 115° = 180°

∠b= 180 - 115

∠b = 65°

Answer:

3rd choice: sec(a) = 1.06

Step-by-step explanation:

sec(a) = (hypotenuse)/(adjacent leg)

The statement that is accurate for the right triangle shown below is C. sec(a) = 1.06

The accurate statement is the one that can help us arrive at the correct angle in the diagram. That is sec(a) = 1.06. The formula is given as follows:

(hypotenuse)/(adjacent)

In the question we have, the hypotenuse is 50 while the adjacent is 47. Note that the hypotenuse is the longest side of the triangle, and the adjacent is often represented by the base.

So, we have;

50/47 = 1.06

Thus to find the angle for alpha in the triangle shown, the right statement would be; sec(a) = 1.06.

The complete factor of the polynomial expression is (x² + 9)(x – 1)(x + 1), then the correct option is B.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The expression is given as

x⁴ + 8x² – 9

Then by the factorization, we have

x⁴ + 8x² – 9

x⁴ + 9x² – x² – 9

x²(x² + 9) – 1(x² + 9)

(x² + 9)(x² – 1)

The equation that can be solved to determine x, the number of hours after which the costs would be the same is; 50x + 250 = 75x + 100

The general formula for the slope intercept form of an equation is;

y = mx + c

We are told that;

Charge per hour = $50

Ownership rights = $250

Thus, for the first company, total cost is;

y = 50x + 250

For the second company;

Total cost is;

y = 75x + 100

Thus, at same cost, we have;

Answer:

36 m

Step-by-step explanation:

PT = x

This is True because of similar sides  [tex]\frac{8}{x} = \frac{7}{14}[/tex]

solve for x to get PT and you get 16

Then to find the perimeter you would do P = PR + PR + PT = 6m + 14m + 16m = 36m

Answer:

36 m

Step-by-step explanation:

Line QS = (1/2) Line PT

8 m = (1/2) Line PT

Line PT = 16 m

Perimeter = 3 + 3 + 7 + 7 + 16

P = 36 m

Using the slope concept, it is found that rhe blade's length is of 90 feet.

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem, the horizontal change is of 440 feet.

At the highest point, the angle is of 38º, hence:

[tex]\tan{38^\circ} = \frac{h_1}{440}[/tex]

[tex]h_1 = 440\tan{38^\circ}[/tex]

[tex]h_1 = 344[/tex]

At the lowetst point, the angle is of 30, hence:

[tex]\tan{30^\circ} = \frac{h_2}{440}[/tex]

[tex]h_2 = 440\tan{30^\circ}[/tex]

[tex]h_2 = 254[/tex]

Hence, the difference is:

[tex]h_2 - h_1 = 344 - 254 = 90[/tex]

The blade's length is of 90 feet.

Answer:

what you mean about circles but i do know probability

Step-by-step explanation:

conditional probability is a measure of the probability of an event occurring, given that another event has already occurred.

A heptagon has seven sides. The measure of the final interior angle of the heptagon is 124°.

A heptagon, sometimes known as a septagon, is a seven-sided polygon. The heptagon is also known as the septagon, which combines the prefix "sept-" with the Greek suffix "-agon," which means "angle."

A heptagon has 7 sides therefore, the sum of the interior angle of the heptagon can be written as,

[tex]\text{Sum of intetrior angles of a polygon with n sides} = (n-2)\times 180^o\\\\\text{Sum of all the angle of heptagon} = (7-2) \times 180^o = 900^o[/tex]

As it is said in the problem that the sum of the all the angles of the heptagon  except one is 776°, therefore, the measure of the last angle of the heptagon is,

The measure of the last angle = 900° - 776° = 124°

Hence, the measure of the final interior angle of the heptagon is 124°.

Based on given information about pressure from table and geometry of the solid shape, the total volume of the solid shape is approximately 21073.745 cubic centimeters. [tex]\blacksquare[/tex]

In this question we must apply the concepts of pressure (P), in newtons per square meter, cross section area (A), in square meters, and volume (V), in cubic meters, to determine that  Let assume that the bottom experiments an uniform pressure due to a reaction force (F), in newtons, from the table, whose formula is described below:

P = F/A = 4 · F /(π · D²)     (1)

If we know that F = 4 N and P = 100 N/m², then the diameter of the cylinder is:

[tex]D = 2\cdot \sqrt{\frac{F}{\pi\cdot P} }[/tex]  

D ≈ 0.226 m²

And the volume of the solid shape is: (H = 0.45 m)

V = 0.25π · D² · H + (π/12) · D³

V = 0.25π · (0.226 m)² · (0.45 m) + (π/12) · (0.226 m)³

V ≈ 0.021 m³ (21073.745 cm³)

Step-by-step explanation:

The easiest common denominator to find is the product of the denominators you have.

__

The difference is ...

  [tex]\dfrac{5}{6}-\dfrac{1}{8}=\dfrac{5}{6}\cdot\dfrac{8}{8}-\dfrac{1}{8}\cdot\dfrac{6}{6}\\\\=\dfrac{40-6}{48}=\boxed{\dfrac{34}{48}}[/tex]

__

Additional comment

The difference numerator and denominator have a common factor of 2, so can be reduced to 17/24. The denominator 24 could have been used as the common denominator from the start.

  5/6 -1/8 = 20/24 -3/24 = 17/24 . . . . reduced result

__

Using the least common denominator does not always result in a reduced sum or difference. If some other denominator is used (as here), then you can be assured that the result will need to be reduced to get to lowest terms.
