Step-by-step explanation:
A regular n-sided polygon has n lines of symmetry. If n is odd, each line of symmetry passes through only one vertex. If n is even, half the lines pass through two vertices, and half pass through none.
So if a line passes through two vertices, the polygon must have an even number of sides.

A bank gives two dollars in eastern caribbean currency for one united states dollar. Given 1% tax is charged on all foreign exchange transactions, calculate the amount in ec currency which a tourist receives in exchange for us 1200
Answer:
A tourist receives 2376 ec currency in exchange for us 1200.
Step-by-step explanation:
This can be calculated as follows:
Tax rate = 1%
Amount of us currency = 1200
Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400
Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24
Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376
Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.
Therefore, a tourist receives 2376 ec currency in exchange for us 1200.
A boat goes 3/4 hours with a speed of 8mph and 1/3 hours with a speed of 12mph. What distance did the boat cover in all this time?
Answer:
10 miles
Step-by-step explanation:
Distance d = v t
v - speed/velocity
t - time
d = [tex]\frac{3}{4}[/tex] (8) + [tex]\frac{1}{3}[/tex] (12) = 6 + 4 = 10 miles

Which number is divisible by 5 and 10?
A.24503
B.24305
C.23450
D.23405
Answer:
C
Step-by-step explanation:
a number is divisible by 5 if it ends in 5 or 0
since we know that, we know that A is not correct.
a number is divisible by 10 if it ends in 0
from this, we can see that C is the correct answer because it ends in a 0
answer=c

Using the information given, select the statement that can deduce the line segments to be parallel. If there are no
then select none.
When m7=24
AB || DC
AD II BC
none
Answer:
b. AD II DC
math is annoying, a lot of the stuff they teach we don't use in the real world lol
Answer:
If anything, AB DC seems like it would be right because AD BC doesnt line up with angles real well. Im not entirely sure; educated guessing.

Simplify. Use the distributive property. 5(3x+1)
Answer:
15x+5
Step-by-step explanation:
First you distribute the 5 to the 3x ( 5 times 3x=15x)
Next you distribute the 5 to the 1 (5 times 1=5)
Finally you put the two answers together 15x+1
you cant simplify it anymore because you cannot add 15x to 1
[tex]\huge\boxed{Hello\:there!:)}[/tex]
The Distributive Property states that
a(b+c)=ab+ac (we multiply a by b and c)
Let's use this fantastic property to solve our problem:
5(3x+1)
15x+5
That's our final answer.
Remember, we can't add variables and numbers together.

What is an equation of the line that passes through the points (0,8) and (-5,4)? Put your answer in fully reduced form.
X+y=8 You can find more Solutions by replacing x with other values and then solving for Y. For example, let X = 6. What is y? ... the solutions of x+y=8 x is 5 and y is 3
Answer:
Step-by-step explanation:
x + y = 8 ⇔ y = - x + 8
If x = 6 , then y = - 6 + 8 = 2
( 6, 2 )
If x = 0 , then y = 0 + 8 = 8
(0, 8)
If x = 8 , then y = - 8 + 8 = 0
(8, 0)

A line includes the points (-39,49) and (0,0). What is its equation in slope-intercept form?
Answer:
The equation in the slope-intercept form will be:
[tex]y=-\frac{49}{39}x+0[/tex]
Step-by-step explanation:
Given the points
(-39,49) (0,0)Finding the slope between the points using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-39,\:49\right),\:\left(x_2,\:y_2\right)=\left(0,\:0\right)[/tex]
[tex]m=\frac{0-49}{0-\left(-39\right)}[/tex]
[tex]m=-\frac{49}{39}[/tex]
We know that the point-slope of the line equation is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting [tex]m=-\frac{49}{39}[/tex] and (-39,49) in the equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]
Now writing the equation in slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
[tex]y-49=\frac{-49}{39}\left(x-\left(-39\right)\right)[/tex]
[tex]y-49=\frac{-49}{39}\left(x+39\right)[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]
[tex]y-49=-\frac{49}{39}\left(x+39\right)[/tex]
[tex]\mathrm{Add\:}49\mathrm{\:to\:both\:sides}[/tex]
[tex]y-49+49=-\frac{49}{39}\left(x+39\right)+49[/tex]
[tex]y=-\frac{49}{39}x+0[/tex] ∵ [tex]y=mx+b[/tex]
Where
[tex]m=-\frac{49}{39}[/tex] and the y-intercept i.e. [tex]b=0[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=-\frac{49}{39}x+0[/tex]

Answer:
x=12
Step-by-step explanation:
(2x-4)/5=4
We move all terms to the left:
(2x-4)/5-(4)=0
We multiply all the terms by the denominator
(2x-4)-4*5=0
We add all the numbers together, and all the variables
(2x-4)-20=0
We get rid of parentheses
2x-4-20=0
We add all the numbers together, and all the variables
2x-24=0
We move all terms containing x to the left, all other terms to the right
2x=24
x=24/2
x=12
Answer:
x = 12
Step-by-step explanation:
Given
[tex]\frac{2x-4}{5}[/tex] = 4 ( multiply both sides by 5 to clear the fraction )
2x - 4 = 20 ( add 4 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12

Answer:
Solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]
Step-by-step explanation:
We need to solve:
[tex]6^2-(1.1+7.4)+1.5[/tex]
First solving brackets
[tex]=6^2-(8.5)+1.5\\=6^2-8.5+1.5\\[/tex]
Now solving 6^2
[tex]=36-8.5+1.5\\[/tex]
Now subtracting 8.5 from 36
[tex]=27.5+1.5[/tex]
Now adding the above values
[tex]=29[/tex]
So, solving [tex]6^2-(1.1+7.4)+1.5[/tex] we get [tex]\mathbf{29}[/tex]
