3 Amy wants new skirting boards in her living room.
The skirting boards will
go along the bottom of each wall
not go across the doorway
not go across the fireplace.
.
Amy has this sketch of her living room.
6.5 m
4.5 m
doorway
900 mm
fireplace
1.2m
Skirting boards come in lengths of 2.4m
The lengths of skirting board can be cut and joined.
Answer:
skirting boards lenghts 11.31 m
Step-by-step explanation:
1) find the area A=LxW
A= 6.5 x 4.5= 29.25 m2
2) Once you have found the area you subtract it from the doorway and fireplace
doorway 900 mm= 0.9
fireplace 1.2m
29.25-0.9- 1.2= 27.15 m2
3) then you find the perimeter
6.5+4.5+6.5+4.5= 22
22-0.9-1.2= 19.9
you divide the answer with the skirting board lenghts= 19.9: 2.4= 8.29
which is approximately 9m of skirting board

Which value is closest to the perimeter of the window
Answer:
9.82 feet
Step-by-step explanation:
the perimeter of the window is the circumference of a semi-circle with a diameter of 5
P = (πd)/2 (divided in half because it's only half a circle)
P ≈ 3.14(3.5) which is approx 11
11 is closest to 9.82
Answer:
9.82 Is the Closest
Step-by-step explanation:
First of all, you can see its a half circle, meaning if we make it a full circle, the length of the center is 5, so the full circle's area is about 19.5-20. Now to find the area of the half circle/windows we get 9.75 - 10. The only number between that is 9.82, which should be you answer.
Have a nice day!

Find the distance between the two points rounding to the nearest tenth (if
necessary).
(4,4) and (-2,-4)
Answer:
10
Step-by-step explanation:
d² = (x2 - x1)² + (y2 - y1)²
d² = (-2 - 4)² + (-4 - 4)²
d² = (-6)² + (-8)²
d² = 36 + 64
d² = 100
d = 10

Solve the following quadratic by
completing the square.
y = x2 + 2x – 6
x =
[?]+)
Answer:
x = - 1 ± [tex]\sqrt{7}[/tex]
Step-by-step explanation:
let y = 0
x² + 2x - 6 = 0 ( add 6 to both sides )
x² + 2x = 6
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = 6 + 1
(x + 1)² = 7 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )
x = - 1 ± [tex]\sqrt{7}[/tex] , that is
x = - 1 + [tex]\sqrt{7}[/tex] , x = - 1 - [tex]\sqrt{7}[/tex]

when a number is doubled andthen eight added it became 60 what is the number
Answer:
26
Step-by-step explanation:
All I did was 60-8
(52)
Then 52/2
26
Answer:
26
Step-by-step explanation:
1) A number is doubled. This number will be represented by X.
8 + (X • 2) = 60
2) Subtract 8 from both sides of the equation
(X • 2) = 60 - 8
3) Simplify the equation
X • 2 = 52
4) Divide each side of the equation by 2
X = 52 ÷ 2
52 ÷ 2 = 26
5) Simplify the equation
X = 26

The swimming pool shown below is a right prism with concave hexagonal bases. The owners of the pool want to paint the sides and bottom of the pool. If one gallon of paint covers 400 square feet, how many gallons of paint will be needed to paint the inside of the pool?
Answer:
2.21 gallonsStep-by-step explanation:
Area of sides:
2(10*3 + 1/2(14 + 10)*6) = 204 square feetArea of the bottom:
20(3 + 10 + 5 + 10 + 6) = 680 square feetTotal area:
204 + 680 = 884 square feetPaint needed:
884 / 400 = 2.21 gallons(x + 10) = (2x - 30).
Answer:
x = 40
Step-by-step explanation:
x + 10 = 2x - 30
40 = x
40 + 10 = 2(40) - 30
50 = 50

a sphere has a volume of 850 m^3 find its surface area
Answer:
SA ≈ 434.5 cm²
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )
The surface area (SA) is calculated as
SA = 4πr²
To find r use the volume formula
[tex]\frac{4}{3}[/tex]πr³ = 850 ( multiply both sides by [tex]\frac{3}{4}[/tex] to clear the fraction )
πr³ = 637.5 ( divide both sides by π )
r³ = [tex]\frac{637.5}{\pi }[/tex] ( take the cube root of both sides )
r = [tex]\sqrt[3]{\frac{637.5}{\pi } }[/tex] ≈ 5.88 cm ( to 2 dec. places )
Then
SA = 4π × 5.88² ≈ 434.5 cm² ( to 1 dec. place )

Help me plz and show work
Answer:
substitute the value of y into the equation 7x+3y = 35
7x + 3(x+5) = 35 (distribute 3 through the parenthesis)
7x + 3x + 15 = 35
collect the like terms
7x + 3x = 35 - 15
10x = 20 (divide both sides by 10)
x = 2
substitute x = 2 into the equation y = x + 5
y = 2 + 5
y = 7

angle c = ___ degrees
Answer:
angle c = 83 degrees
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral add up to 180 degrees.
According to the rule, <D and <B add up to 180° and same for <A and C.
This means that the sum of (x + 100) and (3x) equal 180.
Therefore (x + 100) + (3x) = 180 →
4x + 100 = 180
–100 –100
4x = 80
÷4 ÷4
x = 20.
Since x = 20, <A = 5x – 3 = 5(20) – 3 = 97.
Since <A + <C = 180.
97 + <C = 180 → 97 + <C = 180
–97 –97
<C = 180 – 97 = 83°
