There are two equation of the system
(1) The perimeter
2(w + l) = p
2(w + l) = 86
(2) The length and the width
2w = l + 2
From the second equation
2w = l + 2
l + 2 = 2w
l = 2w - 2
Subtitute l with 2w - 2 in the first equation to find the width
2(w + l) = 86
2(w + 2w - 2) = 86
2(3w - 2) = 86
6w - 4 = 86
6w = 90
w = 15
Now, find the length by subtituting w with 15
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28
The dimension of the rectangle
length = 28 cm
width = 15 cm

The angle measures of a triangle are shown in the diagram below. What is the value of x?
Answer:
30°, see explanation below!
Step-by-step explanation:
Hewo Again!
And for your question.
All of the inside angles of a triangle added together equals 180°!
So:
2x+2x+2x=180
6x=180
x=30°
Answer:
30
Step-by-step explanation:
i believe it is 60 because an equilater triangle like that has its angles as 60° and 60 ÷ 2 is 30.

Answer:
A = 1/2(10×6)
A = 1/2(16+11)×(7)
Step-by-step explanation:
The height is the hardest to find for each, so to find which goes where youd need to find what's straighter.
Like the triangle, to find the height youd need to flip it around to see what measurement is the straightest.
Same goes for the height of the Trapezoid

Step-by-step explanation:
if the volume of a cylinder is given by v=pi*h*r^2 lets find each volume and find their ratio. volume of a is 50.24 and volume of c is 200.96. so the ratio is 200.96:50.24. let's simply this by saying 200.96/50.24 to see how many of the smaller cylinders A it takes to equal 1 of the larger cylinder C. it is 4. the ratio is 1:4. 1 large cylinder C is equal to 4 smaller cylinders A
Help me please and thank you :)
Answer:
A. 74 cm
Step-by-step explanation:
First, we break the rhombus down into similar shapes,
The area of 2 triangles = The area of a square
So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,
10 multiplied by 5 =50
Thats the area of rectangle 1
Rectangle 2
3 multiplied by 6 = 18
Triangle
4 times 3 divided by 2 = 6
Thus
6 + 18 + 50 = 74

A container is shaped like a rectangular prism and has a volume of 72 cubic feet. Give four different set of measurements that could be the dimensions of the container.
Need the answer to all dem ASAP!!!
Answer:
The formula for the volume of a prism is V = Bh
where,
B is the base area
h is the height.
Since, the base of the prism is a rectangle, therefore, volume of a rectangular prism = (L * B) * h
Assumptions:
Length, L and Width, B cannot be the same.
1.
h = 4 ft
B = 2 ft
L = 9 ft
2.
h = 4 ft
B = 3 ft
L = 6 ft
3.
h = 6 ft
B = 2 ft
L = 6 ft
4.
h = 2 ft
B = 2 ft
L = 18 ft

Part A: Identify the Minimum, First Quartile, Median, Third Quartile, and Maximum for the data.
64, 53, 60
60, 56, 58
51, 55, 60
A. Minimum: 51, First Quartile: 55, Median: 58, Third Quartile: 60; Maximum: 64
B. Minimum: 51, First Quartile: 55.5, Median: 59, Third Quartile: 60; Maximum: 64
C. Minimum: 51, First Quartile 54.5, Median: 57, Third Quartile: 60; Maximum: 64
D. Minimum: 51, First Quartile: 54, Median: 58, Third Quartile: 60; Maximum: 64
Answer:
Yes! This is my area!
Step-by-step explanation:
Minimum= 51
Maximum=64
To find the median put the numbers in order
51,53,55,58,60,60,64
no cross off one by one to get the middle number
you end up with 58
first quartile is the upper half so that would be 53
third quartile is the lower half so that wou;d be 60
Hope this helps!
Answer:
D
Step-by-step explanation:
when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64
the minimum is the smallest number in the data set. the maximum is the largest number in the data set.
the median is the measure of center, which indicates the middle number in the data set
the first quartile is the center of the bottom set of the data
the third quartile is the center of the upper set of the data
(the upper and lower sets are indicated by which side of the median they are on)

Answer:
Step-by-step explanation:
Supplementary means 2 angles adding up to 180 or the line of AEF in this case
so supplementary pairs like DEH and HEF would add up to 180, same with DEJ and JEF
Answer:
Angle DEH and angle HEJ and HEK and KEF add up to 180 degrees
Step-by-step explanation:
Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.
