Answer:

Answer:

The most correct option is;

(B) 958.2 ft.²

Step-by-step explanation:

From the question, the dimension of each square = 3 ft.²

Therefore, the length of the sides of the square = √3 ft.

Based on the above dimensions, the dimension of the small semicircle is found by counting the number of square sides ti subtends as follows;

The dimension of the diameter of the small semicircle = 10·√3

Radius of the small semicircle = Diameter/2 = 10·√3/2 = 5·√3

Area of the small semicircle = (π·r²)/2 = (π×(5·√3)²)/2 = 117.81 ft.²

Similarly;

The dimension of the diameter of the large semicircle = 10·√3 + 2 × 6 × √3

∴ The dimension of the diameter of the large semicircle = 22·√3

Radius of the large semicircle = Diameter/2 = 22·√3/2 = 11·√3

Area of the large semicircle = (π·r²)/2 = (π×(11·√3)²)/2 = 570.2 ft.²

Area of rectangle = 11·√3 × 17·√3 = 561

Area, A of large semicircle cutting into the rectangle is found as follows;

A_((segment \, of \, semicircle)) = (1)/(4) * (\theta - sin\theta) * r^2

Where:

\theta = 2* tan^(-1)( (The \, number \, of  \, vertical  \, squrare  \, sides  \ cut  \,  by  \  the  \  large  \,  semicircle)/(The \, number \, of  \, horizontal \, squrare  \, sides  \ cut  \,  by  \  the  \  large  \,  semicircle) )

\therefore \theta = 2* tan^(-1)( (10\cdot √(3) )/(5\cdot √(3)) ) = 2.214

Hence;

A_((segment \, of \, semicircle)) = (1)/(4) * (2.214 - sin2.214) * (11\cdot√(3) )^2 = 128.3 \, ft^2

Therefore; t

The area covered by the pavers = 561 - 128.3 + 570.2 - 117.81 = 885.19 ft²

Therefor, the most correct option is (B) 958.2 ft.².

This is urgent!!! Increase £400 by 3.2% how do you do it

Answers

to get 3.2% : 400 x  (3.2)/(100) = 12.8

12.8 + 400 = £412.80
10% of 400 = 40
1% of 400 = 4
0.1% of 400 = 0.4

(3 x 1%) + (2 x 0.1%) = 3.2%
3.2% = 12.8

Find the product. -mnp(3m - 5n 7p)

Answers

If you would like to find the product, you can calculate this using the following steps:

-mnp * (3m - 5n7p) = -mnp * 3m + mnp * 5n7p = -3m^2np + 35mn^2p^2

The correct result would be -3m^2np + 35mn^2p^2.

Brandie lives on the twelfth floor of her apartment building. She walks down 2 flights to visit a friend, then up 3 flights to deliver a message to a neighbor. Which integer best represents the number of flights Brandie must walk to get back to her starting point?A.–12
B.–1
C.5
D.7

Answers

Answer:

Option B. -1

Step-by-step explanation:

Brandie lives on the twelfth floor of her apartment building.

She walks down 2 flights to visit a friend = 12 - 2 = 10th floor

Then up 3 flights to deliver a message to a neighbor = 10 + 3 = 13th floor

Now Brandie walk to get back to her starting point that is 12th floor, she must walks down 1 flight.

So the answer would be option 'B' -1

B.-1 because she started on the twelfth floor she walks down 2=10 and then back up 3=13 so she has walk down 1 flight to get back.

Which value, when placed in the box, would result in a system of equations with infinitely many solutions?y = 2x – 5

2y – 4x =

Answers

For a system of equations to have infinitely many solutions it must describe identical lines.
If you multiply the first equation by 2, then move the x term to the left side, you would get 2y-4x=-10
Final Answer:
-10

Solve the following system:y = x + 3
2x + y = 9

(2, 5)
(5, 2)
(−2, 5)
(2, −5)

Answers

Hi,

y = x+3
2x+y = 9

2x+(x+3) = 9
2x+x+3 = 9
3x+3 = 9
3x = 9-3
3x = 6
x = 6/3
x = 2

y = x+3
y = 2+3
y = 5

Answer:

(x,y) = (2,5)

ahhh easy:) all we have to do is plug in y
sooo this question becomes 
2x + x + 3 = 9 
we add the xs and they become 3x
soooo
3x + 3 = 9 
now subtract 3 from both sides
3x +3 = 9 
     - 3 = -3 
they cancel out on the left hand side and the right side of the equal sign becomes a 6 
sooooo
3x = 6 
divide both sides by 3 
3x = 6 
÷3 = ÷ 3
the 3s on the left side cancel out
and the right side becomes 2
sooooo
x = 2 
but before we can answer this completely we plug it into our first equation
soooo
y = x + 3 
to this 
y = 2 + 3 
so y = 5
x = 2 
y = 5 
coordinates?
