Answer:
There are six important properties of parallelograms to know:
-Opposite sides are congruent (AB = DC).
-Opposite angels are congruent (D = B).
-Consecutive angles are supplementary (A + D = 180°).
-If one angle is right, then all angles are right.
-The diagonals of a parallelogram bisect each other.

-4(k+2) = -k+31 i need the steps to solve it
Answer:
k = -13
Step-by-step explanation:
-4(k +2) = -k +31
you multiply the bracket by -4
-4k-8 = -k+31
Collect the like terms
-4k+k = 31+8
-3k =39
divide both sides by -3
k = -13
Answer:
k = -13
Step-by-step explanation:
Distributive property
(-4 x k + -4 x 2)
-4k + -8 = -k + 31
subtract 31 from both sides.
-4k - 39 = -k
add 4k to both sides
-39 = 3k
divide 3 from both sides
-13 = k

Which relationships have the same constant of proportionality between y and x as in the equation y = 1/3 x?
Answer:
C
Step-by-step explanation:
The x is 3 and the y is 1 so if you divide the x by 3 it is 1 which is the y.
The relationships which have the same constant of proportionality between y and x as in the equation y = 1/3x are C and E.
What is the slope of a line?The slope of a line is the ratio that determines the steepness as well as the direction of the line.
How to find the slope of a line?Let the two points on a line be [tex](x_{1} , y_{1} )[/tex] and [tex](x_{2} , y_{2 )[/tex]. The slope can be found as follows:
[tex]\frac{(y_{2} -y_{1} )}{(x_{2} -x_{1} )}[/tex]
The constant of proportionality in the given problem can be understood as the slope of the line. Thus the lines with their slopes as 1/3 will have the same constant of proportionality as the equation y = 1/3 x.
We can observe the graphs given and find their respective slopes. It can be done as follows:
Graph A:(3 - 0)/(0 + 3) = 1
Graph B:(3 - 0)/(1 - 0) = 3
Graph C:(1 - 0)/(3 - 0) = 1/3
Graph D:(29.1 - 4.8)/(9.7 - 1..6) = 3.111
Graph E:(0.8 - 0.5)/(2.4 - 1.5) = 1/3
Therefore, graphs C and E have relationships that have the same constant of proportionality between y and x as in the equation y = 1/3 x.

Otis measured the heights of several sunflowers. He found that their heights were 2,3,5,7, and 8 feet. Otis found that the mean was 5 feet and the range was 6 feet. Which numbers describe the center and spread of this data set? A. 6 feet describes the center, and 5 feet describes the spread. B. 8 feet describes the center and 2 feet describes the spread C. 5 feet describes the center, and 6 feet describes the spread D. 2 feet describes the center and 8 feet describes the spread.
Answer:

Step-by-step explanation:
The solution is : 6 feet describes the center, and 9 feet describes the spread
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.
here, we have,
The center of a data set is mostly considered as the median or the mean
Here mean is 6 (given). And median is also 6.
As 6 is exactly at the middle of the data set. (When arranged in ascending order)
Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.
Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

Find the area of the following shape
Answer:
180mm^2
Step-by-step explanation:
CB = 15^2 + 6^2 = 261, the square root of 261 is ~16mm
CB is 16mm
the area of the triangle is A=ab/2
A=45mm^2
Now you need to find the area of the rectangle
A=l×w
A= 15×9= 135mm^2
now add both areas
(135+45)mm^2=180mm^2

Justin’s tricycle wheel travels about 57 inches in 1 full rotation. What is the diameter of the wheel, to the nearest inch?
Answer:
18 inch
Step-by-step explanation:
In a full rotation, a wheel covers its full perimeter(circumference). Let the diameter be d.
=> circumference = 57 inch
=> πd = 57 inch
=> (22/7) d = 57 inch.
=> d = (57 * 7)/22 inch
=> d ≈ 18.13 inch
=> d = 18 inch (nearest inch)
