Answer:
14) B. 9
15) C. (7 x 3)cm
Step-by-step explanation:
14) The area of of parallelogram ABCD is 63 and the altitude is 7
divide 63 by 7 = 9
15) The length of OC is twice the length of EO so CE = 1(7) + 2(7) = 3(7)
Answer:
14. B
15. C
Step-by-step explanation:
Question 14
Area of a parallelogram = base × altitude
Given:
area ABEF = 63 cm²base = ABaltitude = 7 cmSubstituting the given values into the formula and solve for AB:
⇒ Area = base × altitude
⇒ 63 = AB × 7
[tex]\sf \implies AB=\dfrac{63}{7}[/tex]
⇒ AB = 9cm

Question 15
Median: the line segment from the vertex to the midpoint of the opposite side.
Median Theorem: the medians of a triangle intersect at a point called the centroid. The centroid is two-thirds of the distance from the vertices to the midpoint of the opposite sides.
Therefore,
[tex]\sf CO=\dfrac23CE \implies EO=\dfrac13CE[/tex]
Given:
EO = 7cmSubstituting the given values into the formula and solve for CE:
[tex]\sf \implies EO=\dfrac13CE[/tex]
[tex]\sf \implies 7=\dfrac13CE[/tex]
⇒ CE = (7 x 3) cm

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 8. If there were 6600 no votes, what was the total number of votes?
Answers
Answer:
The total number of voters = 10725
Step-by-step explanation:
The total number of votes cast was 5 + 8
The no votes ratio is 8/ 13
This question is a a proportion question.
A proportion question is 2 ratios equal to other. Three of the parts of the ratios are known and you are asked to find the fourth. In this question the no votes are known to be 8 and the total is 13.
The total no votes = 6600. So the three parts are known are
no vote ratio = 8No vote number =6600total vote ratio part = 13You are asked to find the total number of voters.8/13 = 6600/x Cross multiply
8x = 13*6600 Combine the right.
8x = 85800 Divide by 8
8x/8 = 85800/8
x = 10725
The total number of voters = 10725

Find MQ in parallelogram LMNQ .
Answers
Answer:
MQ = 16.4
By the Parallelogram Diagonals Theorem , MP = PQ
So MQ = 2 · MP
Step-by-step explanation:
Parallelogram Diagonals Theorem
The diagonals of a parallelogram bisect each other, i.e. they divide each other into two equal parts.
P is the point of intersection of the diagonals.
Therefore, MP = PQ and LP = PN
If MP = 8.2, then PQ = 8.2
⇒ MQ = 8.2 + 8.2 = 16.4

Just have a good day
The dimension of the unknown variable x of the deck is equal to 14 feet in length.
What is a Rectangle?A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°).The opposite sides of a rectangle are equal and parallel.
Given in the question is a diagram showing a plan for deck. From the data given, we can write -
Area of Deck = 511 ft.
The value of x can be found out by subtracting the area of the deck from the area of rectangle having dimensions of length 29 ft and width (16 + 4) = 20 ft. The remaining area will be equated to the sum of the area of rectangle at top right corner having dimensions of length 9 ft and width 4 ft and the area of triangle at lower right corner.
Firstly, we will find the dimensions of the triangle at the lower right. The height of the triangle will be = (20 - 9) ft = 11 ft. The base of the triangle will be = 29 - ( x + 9) ft = (20 - x) ft. Now -
[Area of Rectangle (29 x 20)] - [Area of Deck] = [Area of Rectangle (9 x 4) + Area of triangle (lower right)].
Mathematically -
580 - 511 = 9 x 4 + 1/2 × (20 - x) × 11 = 69
36 + 5.5(20 - x) = 69
36 + 110 - 5.5x = 69
146 - 69 = 5.5x
5.5x = 77
x = 14 ft
Therefore, the dimension of the unknown variable x of the deck is equal to 14 feet.

The length of a rectangle is 2ft longer than it’s width. If the perimeter of the rectangle is 32 ft, find it’s area
Answers
Answer:
Area of rectangle is 63 feet²Step-by-step explanation:
Given:
The length of a rectangle is 2ft longer than it’s width. If the perimeter of the rectangle is 32 ftTo Find:
Area of the rectangle.Solution:
Let's assume Width of rectangle be x feet and length be 2 +x. to Find the are of the rectangle firstly we need to the length and width of the Rectangle:
Using formula:
Perimeter of rectangle = 2(L + B)→ 32 = 2(x + 2 + x)
→ 32 = 2(2x + 2)
→ 32 = 4x + 4
→ 32 - 4 = 4x
→ 28 = 4x
→ 28/4 = x
→ 7 = x
Hence,
Length of the rectangle = 2 + x = 9 feetWidth of the rectangle = x = 7 feet.Now,
→ Area of rectangle = Length × Width
→ Area fo rectangle = 9 × 7
→ Area of rectangle = 63 feet²
Hence, Area of the rectangle is 63 feet²Answer:
63 sq.ft⠀
Step-by-step explanation:
⠀
As it is given that, the length of a rectangle is 2ft longer than it’s width and perimeter of the rectangle is 32 ft.⠀
So, let us assume the width of the rectangle as w ft and therefore the length will (w + 2) ft .
⠀
Now,
⠀
[tex]{\longrightarrow \qquad{ {{\boldsymbol {2 ( Length + Breadth )= Perimeter_{(Rectangle)} }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm{2(w + 2 + {w})= 32 \ }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm 2({2w + 2= 32 ) }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm{4w +4= 32 \ }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm{4w = 28\ }}}[/tex]
⠀
[tex]{\longrightarrow \qquad {\rm{w = \dfrac{28}{4} }}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ \mathfrak{{\pmb{w = 7 }}}}}[/tex]
⠀
Therefore width of the rectangle is 7 ft .⠀
Now, We are to find the length of the rectangle:
[tex]{\longrightarrow \qquad{ {{\rm{Length = w + 2 }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ {{ \rm{Length = 7 + 2 }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ { \frak{ \pmb{Length = 9}}}}}[/tex]
⠀
Now, we are to find the area of the rectangle :
⠀
[tex]{\longrightarrow \qquad{ {{\boldsymbol{ Area_{(Rectangle)} = Length \times Breadth }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ {{ \rm{ Area_{(Rectangle)} = 9 \times 7 }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ { \pmb{\boldsymbol{ Area_{(Rectangle)} = 63 }}}}}[/tex]
⠀
Therefore,
The area of the rectangle is 63 ft².⠀
