A rectangle has an area of 73.5m2 one of the sides are 1.5m in length work out the perimeter of the rectangle
Answer:
101m
Step-by-step explanation:
area of a rectangle is given by length × width
73.5÷1.5 gives us the other side=49

Answer:
0.3 ft DISCLAIMER
Step-by-step explanation:
DISCLAIMER: I am not 100% sure if I am correct. I think I am but there is a chance I am not. I just thought ONE answer would be better than none. Feel free to disregard this if you don't want to try.
If you multiply the starting height (4.5 ft.) by .73 (73%) then you would get the second bounce. I just did that until I got to the 10th bounce and rounded it to the nearest tenth which ended up being 0.3
A circular concrete patio has a circumference of about 53 yards. The patio has a diameter of d yards. Which expression best represents the value of ?.
Applying the expression for the circumference of circle, we found the diameter as 16.86 yards
Mensuration of Flat shapeGiven Data
Circumference = 53 yardsDiameter = d yardsLet us apply the expression for the circumference of a circle
Circumference = 2πr----------1
But r = d/2
hence put r = d/2 in the expression above
Circumference = 2πd/2----------2
Circumference = πd
Substitute our given data
53 = 3.142*d
Make d the subject of formula we have
d = 53/3.142
d = 16.86 yards

What is the area of a circle with a radius of 10.2 feet? 10.2
what is the area of this figure?
Answer:
234 square millimeters
Step-by-step explanation:
You want the area of the irregular polygon shown.
CompositionThere are always several ways you can find the area of a figure like this. In the attachment we have shown extensions of the vertical and horizontal lines that will divide the figure into a triangle and two rectangles.
Triangle areaThe triangle has a base of 12 mm and a height of 13 mm. Its area is ...
A = 1/2bh
A = 1/2(12 mm)(13 mm) = 78 mm²
Rectangle areaThe upper rectangle has a width of 8 mm and a length of 14 mm. Its area is ...
A = LW
A = (14 mm)(8 mm) = 112 mm²
The lower rectangle has a width of 4 mm and a length of 11 mm. Its area is ...
A = (4 mm)(11 mm) = 44 mm²
Total areaThe area of the figure is the sum of the areas of its parts:
total area = triangle area + upper rectangle + lower rectangle
total area = 78 mm² + 112 mm² + 44 mm² = 234 mm²
The area of the figure is 234 square millimeters.

To the nearest cubic meter, what is the total volume of snow used in the snowman?
Considering the spherical snowballs, the total volume of snow used in the snowman is of 126 m³.
What is the volume of an sphere?The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this problem, there are three spheres, of radius r = 1 m, r = 5 m and r = 2 m, hence:
[tex]V_1 = \frac{4\pi}{3} = 4.19[/tex]
[tex]V_2 = \frac{4\pi \times 5^2}{3} = 104.72[/tex]
[tex]V_3 = \frac{4\pi \times 2^2}{3} = 16.76[/tex]
The total volume, in cubic meters, is of:
V = 4.19 + 104.72 + 16.76 = 125.67.
Rounding, the total volume of snow used in the snowman is of 126 m³.

bellamy is building a gate to put on a fence. the gates measurements are 7 feet by 7 feet a diagonal wooden brace is going to be attached to keep the gate rigid what is the length of wood bellany needs to cut for the brace leave your answer in simplified radical form
The length of the diagonal is the hypotenuse of the fence
The length of the wood is [tex]7\sqrt{ 2[/tex] yards
How to determine the length of the wood?The dimensions of the fence are:
7 ft by 7 ft
The length (L) of the diagonal is calculated using:
[tex]L = \sqrt{a^2 + b^2[/tex]
This gives
[tex]L = \sqrt{7^2 + 7^2[/tex]
Express as products
[tex]L = \sqrt{7^2 * 2[/tex]
Express as radical
[tex]L = 7\sqrt{ 2[/tex]
Hence, the length of the wood is [tex]7\sqrt{ 2[/tex] yards

8x +y = 4
-23 – 8= y
Answer:
(2,-12)
Step-by-step explanation:
Correct equations:
8x+y=4
-2x-8=y
------------------
Rearrange the first equation:
8x+y=4
y=4-8x
Now use this value of y in the second equation:
-2x-8=y
-2x-8=4-8x
6x = 12
x = 2
When x = 2:
y=4-8x
y=4-8(2)
y = -12

time switching classes:
w = 7/10

y - 6x - z - w = 0
6x = y - z - w
x = (y - z - w)/6
x = (76/10 - 5/10 - 7/10)/6
x = (76 - 5 - 7)/(10*6)
x = (64)/(10*6)
x = (2*2*2*2*2*2)/(2*5*2*3)
x = (2*2*2*2)/(5*3)
