Answer:
1595 ft^2
Step-by-step explanation:
The answer is obtained by adding the areas of sectors of several circles.
1. Think of the rope being vertical going up from the corner where it is tied. It goes up along the 10-ft side. Now think of the length of the rope being a radius of a circle, rotate it counterclockwise until it is horizontal and is on top of the bottom 20-ft side. That area is 3/4 of a circle of radius 24.5 ft.
2. With the rope in this position, along the bottom 20-ft side, 4.5 ft of the rope stick out the right side of the barn. That amount if rope allows for a 1/4 circle of 4.5-ft radius on the right side of the barn.
3. With the rope in the position of 1. above, vertical and along the 10-ft left side, 14.5 ft of rope extend past the barn's 10-ft left wall. That extra 14.5 ft of rope are now the radius of a 1/4 circle along the upper 20-ft wall.
The area is the sum of the areas described above in numbers 1., 2., and 3.
total area = area 1 + area 2 + area 3
area of circle = (pi)r^2
total area = 3/4 * (pi)(24.5 ft)^2 + 1/4 * (pi)(4.5 ft)^2 + 1/4 * (pi)(14.5 ft)^2
total area = 1414.31 ft^2 + 15.90 ft^2 + 165.13 ft^2
total area = 1595.34 ft^2

Parallelogram EFGH has vertices at E(1,3), F(0,2), G(4,0), and H(5,1). How many units is the perimeter of parallelogram EFGH?
Answer:
the answer wold be 10.129
Step-by-step explanation:
Perimeter of the parallelogram EFGH is 11.76 units
What is Perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length.
What is Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides.
Given,
The coordinates of the parallelogram = E(1,3), F(0,2), G(4,0) and H(5,1)
We know that,
In parallelogram EF=HG and EH=FG
Perimeter of the Parallelogram = 2(a + b)
Distance between EF = a = [tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1}})^{2} }[/tex]
[tex]=\sqrt{(0-1)^{2} +(2-3)^{2} }\\=\sqrt{1+1} \\=\sqrt{2}[/tex]
a =1.41 units
Distance between EH = b =[tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1}})^{2} }[/tex]
[tex]=\sqrt{(5-1)^{2} +(1-3)^{2} }\\=\sqrt{16+4} \\=\sqrt{20}[/tex]
b =4.47 units
Perimeter of the Parallelogram = 2(a + b)
=2(1.41+4.47)
=11.76 units
Hence, the Perimeter of the Parallelogram EFGH is 11.76 units

Jeff read 3/8 (three-eighths) of a chapter of his history book in 20 minutes. At this rate, how many chapters of his history book can he read in 1.5 hours? Explain how he got 27/16?
Answer:
27/16 chapters completed in 1.5 hours
Step-by-step explanation:
Jeff read 3/8 part in minutes = 20
He read complete chapter in minutes =[tex]\frac{20}{\frac{3}{8}}=\frac{20}{3} \times 8 = \frac{160}{3} minutes[/tex]
60 minutes = 1 hour
[tex]\frac{160}{3} minutes = \frac{160}{3} \times \frac{1}{60}=\frac{8}{9} hours[/tex]
So, No. of chapters completed in[tex]\frac{8}{9}[/tex] hours = 1
No. of chapters completed in 1.5 hours = [tex]\frac{1}{\frac{8}{9}} \times 1.5=\frac{27}{16}[/tex]

What is the slope of a line that is perpendicular to the graph of
y = 5/3x +8
Answer:
-3/5
Step-by-step explanation:
The slope of a perpendicular line is always the negative reciprocal of the slope of the original line.
1/(5/3) * - 1 = -3/5
The slope of the line that is perpendicular to the graph of y = 5/3 x + 8 is -3/5.
What is the Equation of line in Slope Intercept form?Equation of a line in slope intercept form is y = mx + b, where m is the slope of the line and b is the y intercept, which is the y coordinate of the point where it touches the Y axis.
Given a line,
y = 5/3 x + 8
Comparing with the slope intercept form,
Slope of the given line = 5/3
Any line perpendicular to the given line has a slope which is the negative reciprocal.
Slope of the perpendicular line = -3/5
Hence the required slope is -3/5.

5. The radius is 40.5
6.The radius is 81
7. The diameter is 18
8.The diameter is 81
9. The diameter is 162 Help please
Answer:
The equation of a circle having the center (a, b) and radius r could be formulated by:
(x - a)^2 + (y - b)^2 = r^2
A circle, which has equation form: (x + 3) ^ 2 + y ^ 2 = 81, can be turned into:
(x - -3)^2 + (y - 0)^2 = 9^2

Q10 A student wants to raise £100 for charity.
He will sell hot dogs at a disco.
The Supermarket
He will make 150 hot dogs.
Hot dog sausages tin of 8 50p
Hot dog buns packet of 6 90p
He buys ingredients at The Supermarket
If he sells all the hot dogs, what is the minimum price he must charge to make a profit of £100?
Show all your working
Answer:
He must charge minimum £0.84 for one hot dog.
Step-by-step explanation:
Ingredients cost for hot dogs at the supermarket,
Price of dog sausages tin of 8 = 50p ≈ £0.5
Price of dog bun packs of 6 = 90p ≈ £0.90
Number of tins required for 150 hot dogs = [tex]\frac{150}{8}[/tex] = 6.25
So student will purchase 7 tins.
Cost of 7 tins = 7 × 0.5
= £3.5
Number of dog buns packets required = [tex]\frac{150}{6}[/tex] = 25
Cost of 25 packs = 25 × 0.9
= £22.5
Total cost of the material used for 150 buns = 22.5 + 3.5
= £26.0
Let the selling price of each hot dog = £x
Then selling price of 150 hot dogs = £150x
Students wants the profit = £100
So, Selling price - Cost price = profit
150x - 26 = 100
150x = 126
x = [tex]\frac{126}{150}[/tex]
x = £0.84
Therefore, he must charge minimum £0.84 for one hot dog.

The probability of pulling a classic rock CD is 0.71 and then without replacement probability of pulling Country side CD is 4.
What is Probability?Probability is the chance that something will happen, or how likely it is that an event will occur.

According to the given question
we have
a bag which contains ,
country music CDs = 4
pop music CDs = 8
classic rock CDs = 5
total number of CDs = 4+8+5 =17
probability of pulling a classic rock CD = [tex]\frac{5}{17}[/tex] =0.71
without replacing
total number of CDs left = 17-1 =16
probability of pulling a country music CD =[tex]\frac{4}{16}[/tex]=4

Mom and her siblings have inherited a 30000 (Square miles) of land. She has 9 sisters and 3 brothers. Each brother has inherited double what each sister has inherited. How many (Square miles) of land mom has inherited?
Answer:
1875 square miles
Step-by-step explanation:
There are a total of 10 women and 3 men. Let's define two variables:
w: land inherited by a womanm: land inherited by a manGiven that they inherited a 30000 (square miles) of land and that each brother has inherited double what each sister has inherited, we can establish the next equations:
2*w = m
10*w + 3*m = 30000
Replacing the first equation into the second one, and solving for w:
10*w + 3*2*w = 30000
16*w = 30000
w = 30000/16
w = 1875 square miles
Your mom, and all of her sisters, inherited 1875 square miles each
