Step-by-step explanation:
Given that,
The area of a circle, [tex]A=36\pi[/tex]
Central angle, [tex]\theta=\dfrac{11\pi}{6}[/tex] = 330
We need to find the area of the sector. The formula for the area of sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{330}{360}\times 36\times 180\\\\A=5940\ unit^2[/tex]
So, the area of the sector is equal to [tex]5940\ unit^2[/tex].
Levi buys cookies and potatoes at the store. He pays a total of 55.69. He pays a total of 5.49 for the cookies
Answer:
Total amount pay for potatoes = 50.2
Step-by-step explanation:
Given:
Levi buys cookies and potatoes
Total amount pay for cookies = 5.49
Total amount pay by Levi = 55.69
Find:
Total amount pay for potatoes
Computation:
Total amount pay for potatoes = Total amount pay by Levi - Total amount pay for cookies
Total amount pay for potatoes = 55.69 - 5.49
Total amount pay for potatoes = 50.2
Why do you think sum or difference formulas will be helpful with finding the exact
ues of uncommon angles?
Answer:
The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

What is the solution to this equation?
8(e)^2x+1=4
Answer:
A
Step-by-step explanation:
hello :
8(e)^2x+1=4
(e)^2x+1=4/8 = 1/2
so : 2x+1 = ln(1/2)
2x = ln(1/2) - 1
x = (ln(1/2) - 1)/2
The solution to the given exponential function is x = [ ln(0.5) - 1]/2
Solving exponential equationsThe standard exponential equation is expressed as y = ab^x
Given the expression
8(e)^2x+1=4
Divide both sides by 8
(e)^2x+1=4/8
(e)^2x+1 = 1/2
Take the ln of both sides
ln(e)^2x+1 ln(1/2)
2x + 1 = ln(0.5)
2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2
Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

- 12 = 6y +18-9y
Answer:
[tex] \boxed{y = 10} [/tex]
Step-by-step explanation:
-12 = 6y + 18 – 9y
[Group like terms 6y and -9y]
-12 = (6y – 9y) + 18
[Simplify the expression]
-12 = -3y + 18
[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]
-12 = -3y + 18
–18 –18
-30 = -3y
[Divide by -3 from both sides, division property of equality, to get the variable y by itself]
-30 = -3y
÷(-3) ÷(-3)
10 = y
[Symmetric property of equality, if b = a, then a = b]
y = 10

Which names one of the legs of the triangle pictured?
Answer:
D
Step-by-step explanation:
the sides are named by the letters in the corners.
One of the legs of the triangle shown in the picture is QL.
What are legs of a triangle?The two sides of the triangle that intersect to determine the right angle are called legs of a triangle.
And the remaining side is called hypotenuse.
According to the given question
In ΔLQJ, we have
Right angle is at Q.
⇒ the sides LQ and QJ are intersecting each other to form right angle at Q.
Therefore, LQ and QJ are the legs of the given triangle LQJ.
Explanation for options
∠LJQ is an angle not a leg.Side LJ is not intersecting with other side to determine the right angle. So, LJ is not one of the leg of the given triangle.∠QLJ is an angle not a leg.QL is one of the leg of the given triangle.Hence, option D is correct. That is QL is the one of the legs of a triangle.

Katya treated everyone in theater to a pizza party. She bought 12 pizzas and six 2-liters of soda. The bill was $137.64 (before tax). The night before, Katya had bought one pizza and one 2-liter of soda for her family, and the bill was $11.95 (before tax). How much was each pizza? How much was each 2-liter of soda?
Let x = the cost of each pizza in dollars
Let y = the cost of each 2-liter of soda (in dollars)
Cost of pizza:
Cost of 2-liter:
I need help with this word problem ASAP. Show work if possible! :)
let the price of pizza and soda( per 2 litre bottle) be x and y
from 1st condition
12x+2y=137.6.....(1)
from 2nd condition
x+y =11.95.......(2)
multiply eq. (2) by 2
2x+2y=23.9.....(3)
subtracting (1) and (3)
12x+2y=137.6
2x+2y= 23.9
10x = 113.7
x=113.7/10
x=11.37
2(11.37)+2y=23.9
22.74+2y=23.9
2y=23.9-22.7
2y=1.2
y=0.6
So the prices of the pizza and soda are 11.37 and 0.6 dollars.
Each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.
Let x be the cost of one pizza, and y be the cost of one 2-liter of soda.
According to the information given, we can write the following two equations:
1. For the pizza and soda purchased for the theater party:
12x + 6y = 137.64
2. For the pizza and soda purchased for Katya's family:
1x + 1y = 11.95
Now, we have a system of two equations with two variables. We can solve it to find the values of x and y.
First, let's solve the second equation for y:
y = 11.95 - x
Next, substitute this value of y into the first equation:
12x + 6(11.95 - x) = 137.64
Now, simplify and solve for x:
12x + 71.7 - 6x = 137.64
Combine like terms:
6x + 71.7 = 137.64
Subtract 71.7 from both sides:
6x = 65.94
Finally, divide by 6:
x = 65.94 / 6
x ≈ 10.99
Now that we have the value of x, which is the cost of one pizza, we can find the cost of one 2-liter of soda using the second equation:
y = 11.95 - x
y ≈ 11.95 - 10.99
y ≈ 0.96
So, each pizza costs approximately $10.99, and each 2-liter of soda costs approximately $0.96.

A rectangular field is 36
meters long and 15 meters
wide How many more meters
18 it to walk on the sidewalk
rother than cutting through
the field diagonally?
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters
