Answer:

[tex]m=2[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in 2 coordinates into the slope formula to find slope m:

(0, 0)

(1, 2)

[tex]m=\frac{2-0}{1-0}[/tex]

[tex]m=\frac{2}{1}[/tex]

[tex]m=2[/tex]

Step-by-step explanation:

7 blue cars out of 38 cars.

To find the percentage you just divide using your calculator and you should get something like this :

[tex]\frac{7}{38}[/tex] = 0.1842105263

Then you just round that to the nearest hundredth.

If you round 0.184 to the nearest hundredth, it will be 0.18 (You have to round down since the number 4 in the thousandth place is smaller than 5)

A line of symmetry will connect a vertex and a midpoint on an opposite side of a regular heptagon  has 7-fold symmetry.

" Symmetry is defined as the line which divides the geometrical shape into two equal proportion."

According to the question,

Regular heptagon is a polygon with 7equal sides.

Line of symmetry will connect a vertex and a midpoint of an opposite sides.

There are seven such possibilities.

Number of lines of symmetry in regular polygon is same number of sides of polygon.

Hence, regular heptagon has 7-fold symmetry.

Answer: The perimeter is doubled

Step-by-step explanation:

When you double the length and width you have 2l as length and 2w as width. The new perimeter is 2(2l)+2(2w)=2(2l+2w). This means that when you double both sides, the perimeter is doubled.

Answer:

the answer willl be 50%  

The 60 percent of 50 equals 30.

To find what number is 60 percent of 30, you can set up the following equation:

0.60 * x = 30

Here, 'x' represents the unknown number that is 60 percent of 30. To solve for 'x,' divide both sides of the equation by 0.60:

x = 30 / 0.60

Now, perform the division:

x = 50

Therefore, 60 percent of 30 is 50. In other words, 50 is the number you are looking for, which is 60 percent of 30. You can verify this by calculating 60 percent of 50:

0.60 * 50 = 30

As expected, 60 percent of 50 equals 30.
