Solution:
The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides.
Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.
Therefore, perimeter of quadrilateral = 5 cm + 7 cm + 9 cm + 11 cm
= 32 cm

D. Graph D
9514 1404 393
Answer:
C. Graph C
Step-by-step explanation:
All of the graphs show the boundary line with the correct slope and y-intercept. To figure which graph, you can ignore everything except "y" and the inequality symbol. That means we're looking at ...
y >
So, the values of y that are solutions are greater than those on the boundary line. The values on the boundary line are not included. This means the shading of the solution area is above the dashed boundary line, as shown in Graph C.
$5.95-$2.29 explained step by step
Answer:
$3.66
Step-by-step explanation:
5.00-2.00 = 3.00
0.95-0.29 = 0.66
3.00 + 0.66 = $3.66 which is the answer
Ok,so:
We don’t need the $ sign now.
So.
1. 5.95 -2.29 which is 3.66!
5 - 2 is 3, and 0.95 - 0.29 is 0.66.
So now add :3 + 0.66 is 3.66
So $3.66!
Hope this helped!

Answer:
558
Step-by-step explanation:
The sum of the first n numbers is ½n(n + 1)
which is the left most number in each row number n
so finding the row containing 526
½n(n + 1) > 526
½n² + ½n > 526
n² + n > 1052
n² + n - 1052 > 0
n > (-1 + √(1² - 4(1)(-1052))) / 2(1)
n > 31.938
so 526 is almost to the end of the 32 row.
The end of that row is ½(32(33)) = 528
so 526 resides two spaces to the right of 528
The end of the row below it, row 33, is ½(33)(34) = 561
As each row is one number longer than the previous row, we count back
2 + 1 = 3 numbers from the end to find what is under 526
561 - 3 = 558

Step-by-step explanation:
The trend line properly describes the data relationship in the scatterplot is plot A.
What is Trend line?A trend line is also known as a line of best fit, and it is used to illustrate the behaviour of a set of data to assess if it is in a given pattern. So, a trend line is an analytical technique that is frequently used in conjunction with a scatter plot to determine whether or not there is a relationship between two variables.
As, per the plots.
The scatter plot A have the points distributed symmetrically on the both side of line.

Does (5, 4) make the equation y = –7x true? Yes Or No
Answer:
No
Step-by-step explanation:
Given point ,
(5,4)Substitute ,
y = -7x 4 = -7*5 4 = -35 ( Not true )Answer:
No
Step-by-step explanation:
Substitute the x- coordinate into the equation and if the value equals the y- coordinate then it makes the equation true.
y = - 7(5) = - 35 ≠ 4
Thus (5, 4 ) does not make the equation true

Answer:15
Step-by-step explanation:
Consider and define which type of slope the line has.
Answer:
think of the numbers as the grid. zero being the middle and each square being 1 2 3 4 5 6 etc to the right of 0 are your positive, -1 -2 -3 etc move to the left of that line, your other access from zero goes up to positive one positive 2 positive 3 etc, from zero down you would be negative one negative 2 negative 3 etc
Answer:
1) (-7, 8) and (-7, 0) - Undefined Slope.
2) (3, 5) and (-1, 2) - Positive Slope.
3) (2, 4) and (5, 1) - Negative Slope.
4) (6, -3) and (4, -3) - Zero Slope.
1) In the coordinates (-7, 8) and (-7, 0), we can see that the first number in both coordinates (the x point) is -7. If the x values are the same, that means that the line does not change at all horizontally/on the x-axis. The only solution to a line that passes through these points would be a vertical line. Vertical lines always have an undefined slope. To test, use the slope formula with the coordinates. y2 is the y in the second coordinate, y1 is the y from the first coordinate, x1 is the x from the first coordinate, and x2 is the x from the second coordinate.
[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]
[tex]\frac{0 - 8}{-7 - (-7)} = slope[/tex] 0 - 8 = -8 and -7 - (-7) = -7 + 7 or 0. Any number divided by 0 is undefined.
2) In the coordinates (3, 5) and (-1, 2) there isn't any obvious abnormality in the coordinates that may cause undefined or 0. We can use the slope formula to find if it has a positive or negative slope.
[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]
[tex]\frac{2 - 5}{-1 - 3} = slope[/tex] 2 - 5 = -3 and -1 - 3 = -4. [tex]\frac{-3}{-4}[/tex] simplifies to 3/4, so the slope is positive.
3) (2, 4) and (5, 1) also don't have any repeating numbers in the coordinates so we can find the slope using the formula.
[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]
[tex]\frac{1 - 4 }{5-2} = slope[/tex] 1 - 4 = -3 and 5 - 2 = 3 [tex]\frac{-3}{3}[/tex] = -1, so the slope is negative.
4) (6, -3) and (4, -3) have the same y values in them, -3. If the y value stays constant then that means the line does not move along the y-axis. This means that it must be a straight line through 1 point on the y-axis. It is a horizontal line. The slope of a horizontal line is always 0 because is straight. You can check using the slope formula.
[tex]\frac{y2 - y1}{x2 - x1} = slope[/tex]
[tex]\frac{-3 - (-3) }{4 - 6} = slope[/tex] -3 - (-3) = -3 + 3 = 0 and 4 - 6 = -2. [tex]\frac{0}{2}[/tex] = 0. The slope is 0.

1. A new drill is used to dig a hole in the ground. At noon, the hole is 13.2 feet deep when the new drill is turned on for the first time that day. At 2 p.m., the drill has dug the hole to be feet deep. The new drill dug 1.5 times as much of the hole as the old drill would have in the same length of time.
(a) What expression represents the number of feet the new drill dug?
(b) How many feet would the old drill have dug in the same length of time? Show your work. Answer the question in a complete sentence.
Using the subtraction and division operation, the depth dug by the new drill, and the depth that would have been dug by the old drill are 29.05 feets and 19.37 feets respectively.
The expression for the number of feets dug by the new drill can be calculated thus :
Final depth - Initial depthDepth dug = 42.25 feets - 13.2 feets
Depth dug = 29.05 feets
The new drill dug 1.5 times the depth that woukd have been dug by the old drill :
Depth dug by old drill = 29.05 / 1.5
Depth dug by old drill = 19.37 feets
Therefore, the depth dug by old drill will be 19.37 feets
