The area of the square= bxh
= 6x6= 36
The area of the rhombus is 4/5 the area of the square so 36x 4/5 = 28.8
Area of rhombus = basexheight
28.8= 6x height
Height = 28.8/6
Height =4.8

A rose garden is formed by joining a rectangle and a semicircle. The rectangle is 33ft long and 21ft wide. If the gardener wants
jeyben [28]

Answer:

The perimeter of the garden is 126.81 feet.                                      

Step-by-step explanation:

We are given the following in the question:

Dimensions of rectangle:

Length, l = 33 feet

Width, w = 21 feet

Dimension of semicircle:

Diameter of circle, d = 33 feet

r = \dfrac{d}{2} = \dfrac{33}{2} = 16.5

Perimeter of garden =

P =\text{(Length + 2(Width)) + Perimeter of semi circle}\\P =l + 2(w) + \pi(r)\\P = 33 + 2(21) + 3.14(16.5)\\P = 126.81

Thus, the perimeter of the garden is 126.81 feet.

X/5-2=x/2+3 solve for x
Makovka662 [10]
Solve for x:x/5 - 2 = x/2 + 3
Put each term in x/5 - 2 over the common denominator 5: x/5 - 2 = x/5 - (10)/5:x/5 - (10)/5 = x/2 + 3
x/5 - (10)/5 = (x - 10)/5:(x - 10)/5 = x/2 + 3
Put each term in x/2 + 3 over the common denominator 2: x/2 + 3 = x/2 + 6/2:(x - 10)/5 = x/2 + 6/2
x/2 + 6/2 = (x + 6)/2:(x - 10)/5 = (x + 6)/2
Multiply both sides by 10:(10 (x - 10))/5 = (10 (x + 6))/2
10/5 = (5×2)/5 = 2:2 (x - 10) = (10 (x + 6))/2
10/2 = (2×5)/2 = 5:2 (x - 10) = 5 (x + 6)
Expand out terms of the left hand side:2 x - 20 = 5 (x + 6)
Expand out terms of the right hand side:2 x - 20 = 5 x + 30
Subtract 5 x from both sides:(2 x - 5 x) - 20 = (5 x - 5 x) + 30
2 x - 5 x = -3 x:-3 x - 20 = (5 x - 5 x) + 30
5 x - 5 x = 0:-3 x - 20 = 30
Add 20 to both sides:(20 - 20) - 3 x = 20 + 30
20 - 20 = 0:-3 x = 30 + 20
30 + 20 = 50:-3 x = 50
Divide both sides of -3 x = 50 by -3:(-3 x)/(-3) = 50/(-3)
(-3)/(-3) = 1:x = 50/(-3)
Multiply numerator and denominator of 50/(-3) by -1:Answer:  x = (-50)/3
