Answer:

21,753 is divisible by 3 and 9

Step-by-step explanation:

A number is  divisible by 2 if last digit of a number is 0, 2, 4 ,6 ,8

A number is  divisible by 3 if sum of digits is divisible by 3.

A number is  divisible by 5 if last digit of a number is 0 or 5

A number is  divisible by 9 if sum of digits is divisible by 9

A number is  divisible by 10 if last digit is 0.

So,  according to these rules  option (a) 3 ,9 is correct

Therefore , 21,753 is divisible by 3 and 9.          

Answer:

[tex](x - y)(x + y + 1)[/tex]

Step-by-step explanation:

[tex]x(x + 1) - y(y + 1)[/tex]

[tex]=> x^{2} + x - y^{2} - y[/tex]

Lets re-arrange it.

[tex]=> x^{2} - y^{2} + x - y[/tex]

Now , lets expand x² - y².

[tex]=> (x + y)(x - y) + (x - y)[/tex]

Taking ( x - y ) common ,

[tex]=> (x - y)(x + y + 1)[/tex]

Answer:

[tex]x(x + 1) - y(y + 1) \\ → {x}^{2} + x - {y}^{2} - y \\→( {x}^{2}- {y}^{2}) + (x - y) \\→ (x - y)(x + y) + (x - y) \\→ \boxed{ (x - y)(x + y + 1)}✓[/tex]

Answer:

Simplify both of them

Step-by-step explanation:

After simplify we get both ratio 2:7 and 10000:35000 are equal.

What is Ratio?

A ratio indicates how many times one number contain in another number.

Given that;

Both ratio are;

2:7 and 10000:35000

Now, Solve the ratio for simplifying;

Ratios are 2:7 and 10000:35000

First ratio is 2 : 7.

Clearly, This is already in simplest form.

Second ratio is 10000:35000

It can be written as;

10000:35000 = 10000/35000

                     = 10/35

                     = 2/7

Thus, After simplify we get both ratio 2:7 and 10000:35000 are equal.

Answer:

C.

Step-by-step explanation:

We have 2 probabilities: Theoretical probability and Experimental probability.

We cant know what will happen as it's just probability but both joe and Jill are making educated guesses based on probabilities, just different kinds.

y + (2x -12) = 180 (since they are supplementary angles)

(2x-12) = 96 ( since they are alternate exterior angle)

2x = 96 + 12

2x = 108

x = 108/2

x = 54.

y+( 2x-12)=180

y+(2× 54 -12) = 180

y + (108-12) = 180

y + 96 = 180

y= 180-96

y = 84.

Step-by-step explanation:

I would take the second job because you will make more. And it has sick time in addition to vacation.

First job:

$15x40=$600 then add in overtime which will be paid at $22.50 (time and half) so $22.50x5=$112.50. Add the two together $600+112.50=$712.50 weekly.

Answer:

(- [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )

Step-by-step explanation:

Given the2 equations

6 - 2x = y → (1)

14 + 3x = y → (2)

Substitute y = 14 + 3x into (1)

6 - 2x = 14 + 3x ( subtract 3x from both sides )

6 - 5x = 14 ( subtract 6 from both sides )

- 5x = 8 ( divide both sides by - 5 )

x = - [tex]\frac{8}{5}[/tex]

Substitute x = - [tex]\frac{8}{5}[/tex] into either of the 2 equations for the corresponding value of y

Substituting into (1)

y = 6 - 2(- [tex]\frac{8}{5}[/tex] ) = [tex]\frac{30}{5}[/tex] + [tex]\frac{16}{5}[/tex] = [tex]\frac{46}{5}[/tex]

solution is ( - [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )

Answer:

The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.

Step-by-step explanation:

According to this question, we have a regular hexagon with a surface area of [tex]18\sqrt{3}\,in^{2}[/tex]. From Geometry, we know that all regular hexagons can be formed by six regular triangles, since the angle of one complete revolution (360º) divided by the number of triangles is equal to the internal angle of each triangle (60º). Then, the area of each triangle is found after dividing the complete area by the number of regular triangles:

[tex]A_{\triangle} = \frac{18\sqrt{3}\,in^{2}}{6}[/tex]

[tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex]

The area of the triangle as a function of the length of the side of the hexagon ([tex]l[/tex]), measured in inches, is determined by this equation:

[tex]A_{\triangle} = \frac{\sqrt{3}}{4} \cdot l^{2}[/tex] (1)

If we know that [tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex], then the length of the side of the hexagon is:

[tex]\frac{4}{\sqrt{3}}\cdot A_{\triangle} = l^{2}[/tex]

[tex]l^{2} = \frac{4\cdot \sqrt{3}}{3} \cdot A_{\triangle}[/tex]

[tex]l = 2\sqrt{\frac{\sqrt{3}}{3}\cdot A_{\triangle} }[/tex]

[tex]l = 2\sqrt{3}\,in[/tex]

The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.

Step-by-step explanation:

Answer:

Angle A = 65

Angle B = 78

Step-by-step explanation:

This is a triangle, and the total angles in a triangle is 180 degrees. What you can do is make all of the angles equal 180 and then solve for x.

180 = (2x +4) + (2x - 9) + x

180 = 2x +4 + 2x - 9 + x

180 = 4x -5 +x

180 = 5x - 5

185 = 5x

37 = x

Now, plug in x to solve for the angles.

Answer:

The positive integer is 3.

Step-by-step explanation:

Let 'x' be the integer

Given that five times of a positive integer is less than twice its square by 3.

so

5 times of x = [tex]5x[/tex]

3 less than twice of the square of x = [tex]2x^{2} - 3[/tex]

so the equation becomes

[tex]5x = 2x^{2} - 3[/tex]

[tex]2x^2-5x-3=0[/tex]

Factorise

[tex]\left(2x+1\right)\left(x-3\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]2x+1=0\quad \mathrm{or}\quad \:x-3=0[/tex]

solving

[tex]2x+1=0[/tex]

Subtract 1 from both sides

[tex]2x+1-1=0-1[/tex]

Simplify

[tex]2x=-1[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{-1}{2}[/tex]

Simplify

[tex]x=-\frac{1}{2}[/tex]

Also solving

[tex]x-3=0[/tex]

Add 3 to both sides

[tex]x-3+3=0+3[/tex]

simplify

[tex]x=3[/tex]

Thus, we got integers:

x = 3 or x = -1/2

Therefore, the positive integer is 3.

Answer:

The equation of the line passing through the points (4, 6) and (0, 6) will be:

The graph of the equation y = 6 is also attached.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the points

Finding the slope between (4, 6)and (0, 6).

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [6 - 6] / [0 - 4]

               = 0 / -4  

               = 0

Thus, the slope of the line = m = 0

The slope m = 0 means the line is horizontal.  Because the slope of the horizontal line is 0.

As the y-values are not changing with respect to the x-values.

Therefore,

The equation of the line passing through the points (4, 6) and (0, 6) will be:

The graph of the equation y = 6 is also attached.
