Answer:

42

Step-by-step explanation:

let the number be x

4/7 of x

(4/7) × x

4x/7

As stated in the question:

x=4x/7+18

=x-4x/7=18

=(7x-4x)/7=18

=3x/7=18

3x= 18×17

3x= 126

x=126/3

x=42

The minimum number of balls that we need to draw to ensure that we get at least 3 even labeled balls is 4

The total number of balls is

Total = 50

Let k represent the minimum number of balls that we need to draw to ensure that we get at least 3 even labeled balls

Using the pigeonhole principle, we have

n + 1 = k

Where n = 3

So, we have

3 + 1 = k

Evaluate the sum

4 = k

Rewrite the equation as

k = 3

Hence, the minimum number of balls that we need to draw to ensure that we get at least 3 even labeled balls is 4

Answer:

  ∠1 = 36°

Step-by-step explanation:

All angles of a regular polygon are congruent, as are the sides. A regular decagon will have 10 congruent angles.

The sum of the measures of the exterior angles of a convex polygon is always 360°. This decagon has 10 congruent exterior angles, so the measure of each is given by ...

  10(∠1) = 360°

  ∠1 = 36° . . . . . . . . divide by 10

Answer:   36°

Step-by-step explanation:   Trust Me!

Answer is correct on Edge.  Good Luck! :)

In the regular decagon shown, what is the measure of angle 1?

360° is always the sum of all measures of all exterior angles of a convex polygon. A decagon have 10 sides.

Since ∠1 = 36°, then each other angle should measure the same, 36°.

In order to know whether the sum of all the angles equal 360°,
we need to multiply:  36° x 10.

36° x 10= 360°.

And sure enough the answer is correct.

Answer:

x - intercept: (3, 0)

y - intercept: (0, 9)

Step-by-step explanation:

This equation is written in standard form,

To find the intercepts it would be easier to put the equation in

slope-intercept form y = mx + b

9x + 3y = 27

subtract 9x from both sides

(9x - 9x) + 3y = 27 - 9x

3y = 27 - 9x

Divided both sides by 3

3y / 3 = 27 - 9x / 3

y = 27 / 3 - 9x / 3

y = - 3x + 9

Now we can plug in x = 0, to find y - intercept:

y = - 3(0) + 9

y = 0 + 9

y = 9

Now we can plug in y = 0, to find x - intercept:

0 = - 3x + 9

0 - 9 = - 3x + 9 - 9

-9/3 = -3x/3

-3 = -x

Answer:

Round the decimal values however needed.

Step-by-step explanation:

The uppercase letters represent the angles, while the lowercase counterparts are the side lengths opposite said angle. For example, side b is opposite angle B.

Angle B is 41 and angle C is 90 because of the square marker. The remaining angle A is...

A+B+C = 180

A+41+90 = 180

A+131 = 180

A = 180-131

A = 49

Or note that

A = 90 - B = 90 - 41 = 49

This shortcut works since we have a right triangle.

---------

That takes care of the angles. Now onto the sides.

We'll need to use trig ratios to determine the missing sides. There are a few approaches, but this is one you could take

tan(angle) = opposite/adjacent

tan(A) = a/b

tan(49) = a/15

a = 15*tan(49)

a = 17.255526 approximately

Furthermore,

sin(angle) = opposite/hypotenuse

sin(B) = b/c

sin(41) = 15/c

c*sin(41) = 15

c = 15/sin(41)

c = 22.863796 approximately

There is another trig function (cosine) that you could use. Also, you could use the pythagorean theorem once you know two sides of the right triangle.

The pythagorean theorem is a^2+b^2 = c^2

Answer:

During the Civil War, the North's heavy industrialization provided an advantage.

According to the information:

The distinct economic division between the northern and southern economies played a key role in the Union's Civil War victory. First, the vast capitalist industry was expanding, with a significant concentration of salaried labor, in full force, and on the verge of the Second Industrial Revolution (to which the development of new military technologies, such as battleships and the mass production of weapons, helped to the war. These northern bourgeois sectors were represented by the liberal nationalist new Republican Party, which worked to enact protectionist laws.

On the other hand, the south remained rooted in an economic structure that was adverse to the growth of capitalism (mechanization and hiring of workers were cheaper than the maintenance of slaves). To protect slavery would be the Democratic Party. This party, which had spearheaded the nation's significant southern expansion (pro-Mexican territorial annexation movement), now served as a proxy for the region's elites, who essentially favored the growth of the slave trade and unrestricted trade in manufactured products and raw resources.

Answer:

  -3√11

Step-by-step explanation:

If the coefficients of a polynomial are rational, any irrational root will have a conjugate that is also a root.

The root 3√11 is irrational, so its conjugate, -3√11, will also be a root.

__

Additional comments

The conjugate of a root of the form a+√b or a+bi will be the same form with the sign changed: a-√b or a-bi.

The conjugate of 3√11 = 0 +√99 will be 0 -√99 = -3√11.

__

A quadratic with rational coefficients can only have irrational roots of the form a±√b, where 'a' and 'b' may be any rational number.

3 - √11  also be a root of f(x).

A polynomial function is a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation like the quadratic equation, cubic equation, etc.

Get the conjugate of any irrational zero if you want rational coefficients.

The conjugate of 3 + √11  is  3 - √11

x = 3 +√ 11

Subtract 3 on both sides

x minus 3 = 3 + √11 - 3

x - 3 = √11

By squaring on both sides

(x - 3)² =√ 11

Now subtract 11 on both sides

(x - 3)² - 11 = 0

To factor use the difference of squares

u² minus v² = (u minus v) (u plus v)

[(x - 3) - 11][(x - 3) + 11] = 0

We get,

(x - 3) - 1 = 0 or (x - 3) + 11 = 0

Solve for x - 3 and x

Add √11 on both sides of first equation and subtract √11 on both sides of second equation

x minus 3 = √11 or x minus 3 = - √11

By adding 3 on both sides

x = 3 + √11 or x = 3 - √11

As a result,

the root of 3 - √11 must likewise be f(x).
