2. Half the perimeter is 9.47, so the perimeter rounded to the nearest unit will be 19 units (C).
The sides parallel to the x-axis are 5 units long. The slanted sides have a rise of 4 for a run of 2, so are √(2^2 +4^2) = √20 ≈ 4.47 units long. Then the perimeter is 2(5 +4.47) = 18.94 ≈ 19.

In the coordinate plane, what is the length of the line segment that connects points at (4, −1) and (9, 7) ? Enter your answer in the box. Round to the nearest hundredth.
Answers
d=√(x2-x1)^2+(y2-y1)2^2
d=√(9-4)^2+(7--1)^2
d=√(5)^2+(8)^2
d=√(25)+(64)
d=√89
d=9.43 units
The length of the line segment is 9.43 units.
Final answer:
The length of the line segment connecting points (4, -1) and (9, 7) in the coordinate plane is approximately 9.43 units, when rounded to the nearest hundredth.
Explanation:
To find the length of the line segment that connects the points (4, −1) and (9, 7) in the coordinate plane, we can use the distance formula which is derived from the Pythagorean theorem:
The distance (Δ) between two points (x1, y1) and (x2, y2) is given by:
Δ = √((x2 - x1)² + (y2 - y1)²)
Substituting the given coordinates:
Δ = √((9 - 4)² + (7 - (−1))²)
Δ = √(5² + 8²)
Δ = √(25 + 64)
Δ = √89
Using a calculator, we can find that:
Δ ≈ 9.43
Therefore, the length of the line segment is approximately 9.43 units, rounded to the nearest hundredth.
find an inequality that you can use to disprove John statement. explain your thinking.
Answers
-x > 0
According to John, we multiply both sides by -1, and the inequality sign does not change direction, so we get this
x > 0
Let's use a number for x that makes the original inequality true.
Let x = -2.
-x > 0
-(-2) > 0
2 > 0
As you can see, -2 does work on the original equation.
Now let's try -2 in John's solution.
x > 0
-2 > 0 which is a false statement.
Now let's solve it again, but we will reverse the inequality symbol when we multiply both sides by -1.
-x > 0
x < 0
Try x = -2.
-2 < 0 which is true
Now it works.
John is incorrect.
If you multiply or divide an equation by a negative number, even if one of its sides is 0, you still must change the direction of the inequality symbol.

To solve this equation, you know what each angle is equal to, and all triangles add to equal 180 degrees, so you can set it up like so:
6x + 2x + 2x = 180 Then combine all the x's and simplify by dividing.
Answer:
36 °
Step-by-step explanation:
Hello
In geometry an interior angle or an internal angle is an angle formed by two sides of a polygon that sharing a common end is contained within the polygon, and the sum of these angles is given by
sum=(n-2)*180°
where n is the number of sides of the polygon,in our case n= 3 (a triangle)
Step 1
find the sum o internal angles
sum=(3-2)*108°
sum=1*180°
(1)sum=180°
step 2
find x
now, according to the graph the sum of internal angles is
sum(graph)=6x+2x+2x
(2)sum=10x
(1) must be equal to (2)
180°=10x
isolating x
x=18
Step 3
find C
by the graph ,we know
C=2x
and x=18
replacing
C=2(18)
C=36°

x = 1

Explanation:
The first given equation is:
-x + y = 5
Multiply this equation by -1, you will get:
x - y = -5 ............> I
The second given equation is:
4x + y = 10 ..........> II
Add the two equations I and II as follows:
x - y = -5
+ 4x + y = 10
..............................
5x = 5
Therefore:
x = 5/5
x = 1
Substitute with x in equation I to get y as follows:
x - y = -5
1 - y = -5
y = 1 + 5
y = 6

What is the MAD of the data set?
{13, 6, 3, 7, 11}
Enter your answer in the box.
Answers
The MAD value of the given data set is "3.2".
Mean absolute deviation (MAD)The average distance between each data value and the mean is defined as the mean absolute deviation of a data set. It is a measure of variation in a data set.
Calculation of the MAD value:
Given:
[tex]\to \{ 13, 6, 3, 7, 11\} \\\\[/tex]
Calculating the sum of the given value:
[tex]\to 13 + 6 + 3 + 7 + 11 = 40\\\\[/tex]
Calculating the average value:
[tex]\to \frac{40}{ 5} = 8\\\\[/tex]
Subtracting the average value from the given set:
[tex]\to 13 - 8 = 5\\\\\to 6 - 8 = | -2 | = 2\\\\\to 3 - 8 = | -5 | = 5\\\\\to 7 - 8 = | -1 | = 1\\\\\to 11 - 8 = 3\\\\[/tex]
Calculated set value:
[tex]\to 5, 2, 5, 1, 3\\\\[/tex]
Adding the set value:
[tex]\to 5 + 2 + 5 + 1 + 3 = 16[/tex]
Calculating the average value of the set:
[tex]\to \frac{16}{5} = 3.2\\\\[/tex]
So, the
[tex]\to \text{MAD} = 3.2[/tex]
Therefore, the final value of MAD is "3.2"

As we are looking for the perimeter of the polygon, we should understand the formula for each figure. For #2, we can clearly see that we have a square, which concludes that the perimeter for the figure is going to be 4S ('S' being the length of one side as all sides are equal).
Let's apply this to our problem.
P = 4S;
S = 6x + 3; set this up as an equation.
P = 4(6x + 3); apply the distributive property to the right side of the equation.
P = 4(6x) + 4(3);
P = 24x + 12
As we can see above, the perimeter of the square in problem #2 is going to be 24x + 12.

Adelaide paid $35 for a manicure and gave the manicurist a 20% tip How much money did Adelaide give her manicurist
Answers
$42.
Explanation:
The best way to find a total bill including tip (or tax if that is what you are looking for - it is found the same way), is to multiply the original total by 1 + the percentage of the tip.
Since the percentage is 20%, we add 0.20 to 1 to get 1.20.
Now we multiply that by the original cost to get the final answer.
1.20*35 = 42
Answer:
Adelaide gave $ 42 to the manicurist.
Step-by-step explanation:
Here, the original price of the manicure = $ 35
Since, 20% tip is given to manicurist,
Thus, the total payment for manicure = Original price of the manicure + 20 % of the original price of the manicure
= 35 + 20 % of 35
[tex]=35+\frac{20\times 35}{100}[/tex]
[tex]=35+\frac{700}{100}[/tex]
[tex]=35+7[/tex]
[tex]=42[/tex]
Hence, Adelaide gave $ 42 to the manicurist.
