What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The formula for circumference of circle is 2πr
The area of circle is πr²
Area of large circle
Given:
circumference = 50.24 m
50.24 = 2 × 3.14 × r
r = 8 m
Therefore Area = 3.14 × 8²
= 200.96 m²
Area of small circle
Given circumference = 25.12 m
⇒ 25.12 = 2 × 3.14 × r
⇒ r = 4 m
Therefore Area = 3.14 × 4²
= 50.24 m²
Area of shaded path area = area of large circle - area of small circle
= 200.96 - 50.24
= 150.72 m²
Hence, the area of the walking path is 150.72 m²

Solve: sin(11pi/2 +x) =-1/2 for [pi, 2pi]
Answer:
Step-by-step explanation:
Given the expression sin(11pi/2 +x) =-1/2
Take the arcsin of both sides
sin⁻¹[sin(11pi/2 +x)] =sin⁻¹(-1/2)
11pi/2 + x = -30
x = -pi/6 - 11pi/2
Find the LCM
x = (-pi-33pi)/6
x = -34pi/6
x = -17pi/3
Since x is negative and sin is negative in the fourth quadrant
x = - 17pi/2
x = -1530⁰+1440⁰ (scaling down the angle)
x = -90
x = 360 - 90 (fourth quadrant)
x = 270⁰
x = 270pi/180
x = 27pi/18
x = 3pi/2
Hence x the solution of x is 3pi/2

Solve this equation. Enter your answer in the box.
–4(x – 26) = –200
Answer:
x = 76
Step-by-step explanation:
Distributive property:-4(x-26) = -4x + 104
Subtract 104 from both sides.-4x + 104 = -200
-4x = -304
Divide -4 from both sides.x = 76
The solution of the equation is x= 76.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given, equation –4(x – 26) = –200
–4(x – 26) = –200
-4x + 104 = -200
-4x = -200-104
-4x = -304
x = 304/4
x= 76
Therefore, the solution of the equation is x= 76.

Explain why the product of 4 x 500 has three Os, not just two Os.
Answer:
because 4 is being multiplied by 500 which has two zeros because it is a multiple of 100
Step-by-step explanation:
Answer:
Because when you multiply 500 by 4 you start with the first 0. 4x0 is 0, now you move on to the second 0. 4x0 is 0, so that one is 0 too. Now you multiply the 5. 5x4 is 20. You put the 20 first, followed by the two 0s, And you get 2,000.

Answer:
25
Step-by-step explanation:
The sum of all of the angles inside of a triangle is 180 degrees. That means we know that:
[tex](x+26)+(x+14)+(4x-10)=180[/tex]
We can then combine like terms:
[tex]6x+30=180[/tex]
We want to get 6x alone, so we can subtract 30 from both sides:
[tex]6x=150[/tex]
Then we want to get x alone, so we can divide both sides by 6:
[tex]x=25[/tex]
Now we know that x is 25.

Step-by-step explanation:
The area of the given triangle JKL is 16 units square.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Given vertices form a triangle in the coordinate plane ;
Base = 3 + 5 = 8 units
Height = 9 - 5 = 4 units.
Since the area of a triangle is given as (1/2) × base × height.
So,
Area = (1/2) × 8 × 4 = 16 unit square.
Hence "The area of the given triangle JKL is 16 units square".

need answers don't know how to do any of them
Answer:
N + B + D = 90 sum of ages is 90 (I)
B = 2 D B is twice as old as D
N + 3 D = 90 using above equations
(N + 10) + 3 D = 100 add 10 to both sides
B + 3 D = 100 Brian is 10 yrs older than Nigel
2 D + 3 D = 100 Brian is twice the age of Dean
5 D = 100
D = 20 Dean's age
Brian = 2 D = 40 Brian's age
90 - 60 = 30 = Nigel's age
Check:
N + 10 = B = 30 + 10 = 40 = Brian's age

The percent of the bin would be filled for 30 gallons of amounts of waste is 60 percent.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a garbage bin can hold 50 gallons of waste.
Waste (gal) = 5
Percentage = 5/50 ×100
= 10%
Waste (gal) = 30
Percentage = 30/50 ×100
= 60%
Waste (gal) = 45
Percentage = 45/50 ×100
= 90%
Therefore, the percent of the bin would be filled for 30 gallons of amounts of waste is 60 percent.

In a café there are 5 different sandwiches, 4 different desserts and 6 different drinks. Two of the desserts are sugar-free and three of the drinks are sugar-free. A meal combination is selected at random work out the probability that both dessert and drink are sugar free
Answer:
the probability that both dessert and drink are sugar free = ¼
Step-by-step explanation:
We are told that there are 5 different sandwiches, 4 different desserts and 6 different drinks.
Now, since Two of the four desserts are sugar free, then the probability that the dessert chosen is sugar free is;
P(desert sugar free) = ½
Now, three of the the 6 drinks are sugar free, then the probability that the drink chosen is sugar free is;
P(drink sugar free) = 3/6 = ½
Thus, the probability that both dessert and drink are sugar free is;
P(both sugar free) = ½ × ½ = ¼

Below.Does it matter the order in which the store applies the discount? In other words, is 70% off and then 20% off equal to 20% off and then 70% off? Give your answer and an explanation below. Make sure to show calculations to support your answer
Answer:
No it does not matter in which order the store applies the discount.
Step-by-step explanation:
Suppose we have the cost price = $ 100
Then 70 % off means 70% of 100= 70 $ discount
And the remaining $ 30 is again given a discount of 20 % . That would be 20 % of $ 30= $ 6 discount giving the discounted price of $ 24.
Now if we apply the discount of 20 % first that would give $ 80 discounted price and again applying 70 % to $ 80 would give $ 56 discount and a discounted price of $ 80 - $ 56= $ 24
Hence the order in which the discount is applied does not matter.

Show your work or explain your answer. B. What is the difference in total population of California and Alaska? Express your answer in scientific notation. Show your work or explain your answer.
Answer:
A. Total area of Alaska is considerable larger than total area of Connecticut.
B. Population of California is considerably larger that population of Alaska.
Step-by-step explanation:
A. What is the difference in total area of Alaska and Connecticut?
According to the US government, total areas of Alaska and Connecticut are 663,268 square miles ([tex]6.633\times 10^{5}[/tex] square miles) and 5,567 square miles ([tex]5.567\times 10^{3}[/tex] square miles), respectively.
The difference between both quantities is:
[tex]x = 6.633\times 10^{5}\,mi^{2}-5.567\times 10^{3}\,mi^{2}[/tex]
[tex]x = 6.577\times 10^{5}\,mi^{2}[/tex]
Which means that total area of Alaska is considerable larger than total area of Connecticut.
B. What is the difference in total population of California and Alaska?
According to the US government, total populations of California and Alaska are 39,512,223 people ([tex]3.951\times 10^{7}[/tex] people) and 710,249 people ([tex]7.103\times 10^{5}[/tex] people), respectively.
The difference between both quantities is:
[tex]x = 3.951\times 10^{7}\,people - 7.103\times 10^{5}\,people[/tex]
[tex]x = 3.880\times 10^{7}\,people[/tex]
Which means that population of California is considerably larger that population of Alaska.
